well as environmental and social,
Until relatively recently, concepts such as "sustainability", "green
transport" and "greenhouse gas emissions" too often tended to be
dismissed as the doomsday ravings of a few deluded fanatics
preaching that the end of the world was nigh.
Today, confronted with unprecedented challenges to our global
climate and economy, we are acutely aware that, without a rapid
shift towards more forward thinking and sustainable lifestyles, we
may indeed be on the verge of a major planetary reckoning.
Hard facts and mounting scientific evidence have replaced the
extremist preaching.
Alongside other sectors, the transport industry must assume its
share of responsibility. The seriousness of the situation calls for our
sector to rise to the challenges and opportunities of the emerging
green economy, so as to reduce the road industry's impacts on the
environment and enable it to contribute pro-actively to a more
sustainable future.
Already, modern road transport systems increasingly reflect the
commitment of road builders, scientists and city planners in these
respects - as well as their growing ingenuity in efforts to ensure
and safeguard a better living environment. Sustainability is
becoming a major watchword, not only at the design phase but
also in the construction and implementation stages of road
schemes. The potential effects of a given road on the environment
are assessed in terms of visual, landscape, biodiversity and other
possible impacts. Factors such as recycling of materials as well as
risks of water contamination, noise pollution and greenhouse gas
emissions are also comprehensively taken into account, alongside
detailed consideration of appropriate measures to avoid or remedy
any issue that may arise.
Whilst there can be no room for complacency, everything seems to
be moving in the right direction, and we are making encouraging
progress on the path to sustainable roads. The legislative climate is
Intr
oduc
tion changing, materials are being recycled, eco-driving awareness is
being promoted and carbon trading and offsetting are gradually
becoming standard practice. More research is being carried out
and more efficient technologies are being made available to
enhance the sustainability of road schemes. And this is only the
beginning. The necessity of sustainable roads has been firmly
established and universally acknowledged. It is now simply a
matter of how many will follow and how quickly.
This publication highlights a series of projects, products and
practices from around the world that have demonstrated
exemplary commitment to the environment and dedication to road
sustainability. It is hoped that they will help set new standards
throughout the road sector, as well as stimulate ongoing progress.
The featured innovations range from advanced traffic signaling
and pavement recycling right down to wildlife protection systems.
They serve as a first reference compilation of model design
considerations, technologies and research applications.
Furthermore, they provide a comprehensive overview of the
various aspects of environmental impact mitigation as they apply
to the road industry, with the aim of setting practical examples and
establishing a basis for the development of best practices.
It is our hope that innovations like these will guide and further
inspire - not only our industry but also the full range of
stakeholders, including the public sector and governments -
regarding the clear economic, as
benefits of sustainable road schemes and eco-friendly projects.

Next to the manufacturing advantages offered by microprismatic sheeting in
general, this product offers additional benefits to road authorities in reducing
investment and maintenance costs for certain traffic signs, as well as reduced
operational energy cost. This is achieved without compromising road safety in
any way. Traditional reflective sheeting processes are based on a multi-layer
coating process. Lower molecular weight polymers are dissolved in various
solvents, coated and dried, where the solvent needs recycling by condensation
and cleaning, or is simply incinerated or released.
A microprismatic manufacturing process uses higher molecular weight polymers
which are extruded on specially embossed cylinders. No solvents are required.
The ability to use high molecular weight polymers during the manufacturing
process provides a better UV and weather resistant retro-reflective film
construction. This results in traffic signs than offer a longer effective life cycle.
Warranties have increased from a maximum of seven years to ten years or more.
In addition to the benefits attributed to standard microprismatic sheeting,
Diamond Grade DG³ sheeting allows the replacement of illuminated signs with
no negative impact on driver behaviour. Replacing illuminated signs by high
performance retro-reflective signs enables authorities to reduce investment and
maintenance costs, and energy consumption.
Environmental BenefitsMicroprismatic retro-reflective sheeting manufacturing uses an innovative process
that minimizes environmental impacts. It reduces VOC emissions by 97%,
consumes 77% less energy, and generates 46% less solid waste compared to a
traditional, beaded reflective sheeting manufacturing process.

3M Diamond Grade DG³ Reflective Sheeting
The benefits for end users and for the environment can be
illustrated by an Illinois Department of Transportation
(IDOT) road agency case study. The agency have begun
switching out all overhead signs on the state's roadways to
use high performance sign sheeting that will improve
visibility. The new signs will also save the state money by
allowing IDOT to remove lighting fixtures used on
overhead signs. The new signs will be put up as old ones
need to be replaced, so the change-over to the higher
performance reflective sheeting is expected to take at least
10 years. The cost is USD 74,000 per year. Once the project
is complete the state could save USD 1 million a year in
maintenance and energy costs. In early spring of 2006,
IDOT installed new sign sheeting on overhead guide signs
along the Illinois Route 15 corridor in St. Clair County. The
purpose was to test this high performance sheeting for
safety, visibility and cost effectiveness. Due to the success
of this pilot project, IDOT is using the new sign sheeting on
replacement signs on the Upgrade 74 project in Peoria and
Chicago's Dan Ryan expressway reconstruction. The

MIMAR is an AEC initiative to improve the knowledge of road users in the
environmental aspects of roads. In Spain and other countries there is a growing
concern about road accidents in which animals are killed. Such accidents are
serious, not only for the species involved but also for the safety of drivers,
passengers and others along the route. Wild boars and foxes are among the
animals frequently involved in accidents. MIMAR is a map, providing road users
with information on: road sections with a high risk of disturbing animals in their
natural surroundings and, consequently, a high risk of accident involving animals;
areas with a high environmental value, due to the diversity of animals or plants
and protected areas. Using MIMAR, road users can increase their general
awareness and adapt their driving accordingly.
Environmental BenefitsMIMAR is part of a wider AEC project developed as the "Programme for
sustainable road maintenance" during 2006 and 2007, with the support of
European Social Funds and Fundación Biodiversidad. The project promotes
environmental training for road maintenance professionals, by developing
training material and additional information in a specific website. The following
environmental impacts of road maintenance operations were analysed:
atmospheric emissions, noise, residues, water spills, water consumption, energy
consumption, soil, wildlife, vegetation, visual.
AEC is the Asociatión Española de la Carretera - the Spanish Road Association. A non profit organisation founded in 1949 to defend and promote the interests of road builders, it became a public utility in 1998. Its current focus is on: road safety, the environment, new technologies, urban mobility and infrastructure service quality. The Association initiates many activities related to technology, education, social campaigns and research - in the form of congresses, seminars, training courses, publications, and information exchange with similar organisations and companies, both nationally and internationally. AEC has been a member of IRF since 1949; it is also the founder member of the Latin-American Institute (IVIA), grouping research and technology centres in South America, and collaborates with the EU, the European Transport Safety Council (ETSC) and OECD.

For each of these impacts, a detailed set of guidelines were developed in order to avoid or minimize the consequences. For
example, for pavement maintenance operations, the environmental effects relate to air pollution, contribution to climate
change, negative impact for population, animals and vegetation and gas emissions. So the following management guidelines
are suggested: avoid tipping materials from high places; use water to lay dust, especially under windy conditions; avoid high
speeds; inform workers, so they know that burning of residues is forbidden; maintain vehicles to a high technical standard.

Roads are the backbone of a flourishing economy. Thanks to new technologies,
they can be built even more environment-friendly. A major step in this direction is
reducing the asphalt temperatures, which has been achieved by new mixing
technologies. As a consequence, asphalt laying asks for faster compaction
technologies. Ammann provides proven solutions to the construction industry for
both of these new challenges.
Asphalt is an ideal material for the construction of high-quality roads, which
consist of several layers of asphalt and gravel. The preparation of the asphalt is
usually done in a central mixing plant, where minerals are dried, heated up and
mixed with bitumen. The hot asphalt is delivered to the road construction side in
lorries and a paving machine is laying the material on the prepared ground.
Finally compactors effect consolidated layers and durability.
Environmental BenefitsLowering the maximum temperature of the asphalt during production and
mixing allows a reduction of fuel consumption at the mixing plants, since less
energy is needed to heat the minerals and the bitumen. The second advantage
of lower temperatures is the significant decrease of asphalt smoke that
construction workers are exposed to.
The Ammann Compaction Expert (ACE) enables the operator of a roller to
choose the optimal vibration mode on the road construction site. Very fast
compaction is achieved and the current level of compaction is measured
Ammann is a leading supplier of machines, systems and services to the construction industry, with core expertise in asphalt and road building worldwide. Driven by an entrepreneurial spirit, the family-owned business founded in 1869 is now in the fifth generation. Ammann develops asphalt plants integrally, from analysis to construction, to maintenance. In addition, it develops and produces compaction machines. The decentralised service points enable fast reaction times.

constantly. Excessive or over-compaction is prevented and in addition, the energy consumption of the machine itself is
minimized. Ammann's intelligent compaction with high-tech measurement and control equipment therefore is a key
enabling technology for the wider application of low-temperature asphalt.
Mere optimisation of the compaction itself is often insufficient to achieve sufficiently fast compaction. Therefore, today's
compaction machines can be controlled using GPS positioning technology (e.g. ACEplus of Ammann). Real-time displays of
machines' current positions, compaction work done and positions were additional compaction is necessary, allow drivers
and construction coordinators to plan the use of their machines. Staying within the narrower time slot for compaction is
now possible. The combination of intelligent compaction modes, positioning technology and on-machine displays allow the
new low-temperature asphalts to be applied on road construction sites. Energy savings thanks to lower process
temperatures can now be realized.

Environmental BenefitsRunning through Snowdonia National Park, Arup's design of the
A470 trunk road in Wales (previous page) provided a safe and
reliable route for road users and preserved a landscape of lush
pastures and diverse flora and fauna. The Shenzhen Western
Corridor (previous page) demonstrates how the planning, design
and construction of a major road can be completed in record
time without compromising the water quality or cultural heritage
of a region's ecologically sensitive area.
The Bingley Relief Road shows how effective community
engagement and sustainable innovative design can reduce traffic
in urban areas and improve a community's quality of life.
Complex challenges included crossing a protected peat bog -
where direct access for construction plant was denied - and
ensuring minimal disturbance to its delicate hydrological and
ecological balance. Sustainability was at the heart of the design
for the M6 Toll Road. Three million tonnes of sand and gravel
excavated from the site was re-used as special fills and aggregates
for concrete and drainage, saving 400,000 lorry journeys to and
from the site. Measures were taken to mitigate the effects of the
route on the local environment including the translocation of
heath land; the relocation of rare plants and wildlife and planting
over one million new trees and shrubs.
At Arup we demonstrate how well considered infrastructure can
be truly sustainable, improve people's lives, enhance the
environment and leave a legacy for the benefit of future
generations.

Attica Tollway is the 65 km stretch of motorway which forms the Athens ring
road, a pioneer project constructed on a concession basis. It is one of the largest
co- financed road projects in Europe. Attica Tollway has two directionally
separated carriageways, each including 3 lanes, plus an emergency lane. It is a
unique piece of European road infrastructure, since it is essentially a closed toll
motorway within a metropolitan capital where the problem of traffic congestion
had been acute. Additionally, heavy traffic conditions were a main cause of
reduced air quality in the surrounding environment.
Environmental BenefitsAttica Tollway has studied and implemented significant noise protection
measures, depending on the configuration and the requirements of each area.
More specifically, noise barriers have been installed, covering an area of several
thousand square metres, as well as buffer zones, and specially planted slopes and
embankments. In order to constantly monitor the levels of air and noise
pollution, six noise measurement stations and eight air pollution measurement
stations operate at key locations along the motorway. The presence of the
motorway has achieved a significant reduction in air pollution and traffic
noise in the city of Athens by reducing congestion. Studies by the local
authorities suggest significant savings in fuel consumption - as free flowing
traffic moving along the motorway consumes on average 60% less fuel
than that travelling on the local urban network. Extensive sewage and
flood protection works were created to collect superficial water run-off, since the
rapid increase of human activity in the area allowed few remaining natural
receptors. This resulted in enhanced flood protection for Athens, transferring
Motorway concessionaires are actively incorporating environmental mitigation into their strategic objectives, considering the issue at every stage of the project's life cycle (from the design and construction to the operation) and bringing infrastructure up to date with modern day norms and standards, incorporating new technology and management practices. Attica Tollway provides positive examples of how environmental management can be incorporated into the construction and management of a motorway, mitigating the impact on the natural environment and bringing environmental and social benefits to the surrounding area.

M6 Toll Road, EnglandEnvironmental BenefitsThe ecoprofile approach requires the use of indicators to evaluate the environmental/health impacts of a product throughout
its life cycle. Somaro typically look at greenhouse gas emissions (climate change), Volatile organic compound (VOC) emissions,
eutrophication of the aquatic environment (asphyxia of aquatic fauna), energy consumed, potential toxicity and waste
generation. The environmental/health balance sheet for the water-based road paint Typhon show impacts at least 30%
lower than for a typical solvent-based paint. Atmospheric VOC emissions are an impressive 88% lower, especially
during the application phase. The PROSIGN G400 airless line marker shows several clear advantages, compared to other
machines/systems: superior operator ergonomics and safety; excellent application quality; centralised control
station management of the main marking work; optimum reliability, safety and service life; lower noise levels.
The two Ostrea products replace the use of quarry lime - eliminating the need for extraction and much of the raw material
transport. They reduce the use of non-renewable petroleum resources and reduce greenhouse gas emissions by
20% on application and over the whole product life cycle and eliminate packaging waste.

The Caterpillar D7E is a new track-type tractor (bulldozer) with electric drive that
increases dozing efficiency by 25% (cubic meters/liter), and lowers operating
costs by 10%. This revolutionary integrated powertrain reduces fuel consumption
by 10 to 30% and uses fewer parts and fluids during its useful life. The D7E also
helps the environment by reducing CO2 and gaseous emissions. The D7E is an
innovative solution that will impact the customer's bottom line and their
environmental footprint.
Environmental BenefitsThe D7E is an innovative new track-type tractor designed to deliver powerful
performance and precise maneuverability while consuming fewer resources. The
most significant design feature is an AC electric drive train, which replaces the
power shift transmission that is typically used in these size track-type tractors.
Electric drive trains have been utilized in other types of construction equipment
(such as off-highway trucks) and other types of transportation equipment (such
as locomotives). The D7E electric drive train is the first of its kind, specifically
designed to meet the demands of a variety of dozing applications, such as
frequent changes in direction, working in harsh conditions and the need to have
very powerful electrical components in a small amount of space (power density).
In addition to the electric drive train, the D7E features a beltless design. The
accessory systems, like air conditioning and the water pump, are electrically
powered so there is no need to repair, adjust or replace engine belts. Additional
innovations such as a center post cab which is combined with a single lift cylinder
For more than 80 years, Caterpillar Inc. has

and aligned with the exhaust stack and the pre-cleaner,
offer a huge increase in visibility. The cab is larger, it's more
comfortable, and there's a 50% reduction in noise for the
operator.
The D7E improves operating efficiency and this is very
important since finding qualified labor is a significant issue
in the construction industry. New operators can be trained
quickly and can be more efficient in a shorter amount of
time. In addition, the D7E comes grade control ready from
the factory and performs extremely well when a grade
control system is utilized. The grade control system utilizes
either laser or GPS signals to help the operator move the
material in an efficient manner and achieve grade. This
improvement in material \movement was not factored into
the reductions but typically results in an additional 30%
improvement in the time to complete a job (due to moving
the material efficiently).

conventional mixes. Vegeflux does not emit volatile organic compounds. 3E asphalt mix saves between 10% to 20%
energy and reduces greenhouse gas emissions from 15% to 25%. Colas recycling techniques save aggregates, transport,
energy; 5 million m2 of roads were recycled by Colas in 2008.
EcologicieL allowed for a 15,000-metric ton reduction in equivalent in CO2 emissions in 2008.

By 2010 Switzerland's CO2 emissions have to be reduced to 90% of those of
1990 (Federal law on CO2 emissions reduction, 1999). Road construction
companies will contribute to this objective. In line with this common aim, Colas
Switzerland developed in 2006 a new asphalt concrete, which is both economic
and ecologically sound. The new product is a cold asphalt concrete, based
entirely on reclaimed asphalt aggregate - VALORCOL The binder used is also a
cold asphalt emulsion, so there is no need for heat during preparation and
mixing. VALORCOL can be used for sub-base course, base course and, in some
conditions, for surface courses. Asphalt aggregates result from the crushing and
sorting of old road superstructures. Gravels, stones and bitumen parts of the
aggregates are of high and proved quality. VALORCOL is manufactured in a
dedicated and simple plant and laid in a traditional way, using normal
equipment. The thicknesses of the layers are comparable to those of traditional
hot asphalt and depend on the result desired.
Environmental BenefitsResource saving. As it uses mainly reclaimed asphalt, VALORCOL saves natural
resources of gravel and stones, which are becoming scarce. It is commonly said
that the first source of granulates in future could be the old road itself! The use
of fossil resources is limited to the bitumen in the emulsion, which is only some
2% of the final product. Traditional asphalt concrete uses between 4 and 6% of
bitumen. The regeneration of old granulates lessens the need for waste disposal.
Limiting transportation: The sources of reclaimed asphalt are commonly closer
to the road work than a quarry. So transportation of materials can be greatly
reduced.

Energy consumption and GHG emission reduction. Through use of cold emulsion, simply prepared aggregates, and
unheated mixing, energy consumption and emissions are both reduced. For the plant in Geneva, it has been calculated that
the GHG emissions are reduced by 300 tons of CO2 each year, if a mere 10% of its asphalt concretes are replaced by
VALORCOL.
A recent roadworks in the Jura used 12,000 square metres of base course and 3,000 tonnes of VALORCOL. Energy and
CO2 savings of nearly 48% were obtained, compared to the traditional use of transported hot bitumen and extracted
aggregates. The energy saving was equivalent to 530 Swiss families' electricity consumption for lighting during one year. The
CO2 saving was 84 tonnes, which is the equivalent CO2 output of a 30 tonne truck covering 87,000 kilometres.

Tyre pile - a basic source of raw material
International Road Federation Innovative Practices for Greener Roads 19
Traffic noise has been identified as a key concern for the public. Noise emissions
from highways adversely affect the quality of life of nearby residents, create
communication difficulties and lower real estate values. In order to reduce noise,
it is first necessary to understand where these emissions are occurring. Studies
have shown that the majority of noise produced from a highway is due to the
tyre/pavement interaction. The mechanisms by which noise is generated in the
tyre/pavement interaction vary, and will be dependent on the match between
tyre characteristics and pavement properties. However, certain effects are
proven: smooth surfaces are quieter than rough surfaces; porous are quieter than
non-porous; elastic are quieter than non-elastic. ECOPATH has sought to achieve
smoothness, porosity and elasticity in paving surfaces in an eco-friendly way.
The pioneering work done by Charles McDonald in the 1960s showed that that
the addition of finely ground scrap tires (crumb rubber) to asphalt yielded an
excellent crack sealant. Since then, CRM binder has emerged as an efficient and
"green" alternative to conventional polymer modified binders, due in part to a
growing environmental sustainability movement, dwindling natural resources,
increased environmental issues, and the quest for improved paving materials.
Research has shown that crumb rubber modification of asphalt binder has many
similar effects to conventional polymer modification. The major changes noted by
researchers are seen with the increase in the high temperature stiffness, these are
often seen to exceed levels normally achieved by conventional polymer
modification. It is this property that is one of the keystones behind the success of
implementing CRM binder in quiet pavements.
ECOPATH is a leading resource for equipment, process design and formulation technology for asphalt rubber (AR) and polymer modified asphalt (PMA) binders. They are prepared to meet customer needs through their scalable technology transfer package. ECOPATH also provides training, project planning, maintenance programmes and blending equipment to satisfy any modified asphalt paving project or requirements.

Environmental BenefitsOne of the principal reasons behind the success of using CRM binder quiet pavements lies in its ability to maintain the "open"
structure of the open graded mixes typically used in quiet pavements. While conventional asphalt binders are typically more
prone to permanent deformation, CRM asphalt binders have been shown in numerous studies to withstand greater
temperatures without deforming. It is not uncommon for crumb rubber concentrations of 20% to be used in CRM binder
formulations; these high concentrations of crumb rubber explain, in part, the significant increase in elasticity typically seen in
pavements using CRM binder.
The need for improved paving surfaces increases, as populations increase, budgets tighten, and environmental consciousness
gains momentum. Therefore, cutting edge materials are necessary to fulfill these requirements; CRM asphalt binder is a
"green" paving a material which exhibits excellent qualities with respect to these demands. Many US state agencies have
achieved significant noise reductions through the use of appropriate pavement design and CRM asphalt binder. The success
of CRM asphalt binders lies in their capacity to provide improved engineering properties, such as reduced noise,
through an environmentally sustainable process.

The Egnatia motorway is a priority project of the Trans-European transport
network and is the communication link spanning northern Greece from its
western to eastern border. Being a collector axis of the Pan-European north-
south corridors, it is of great geostrategic importance for both the Balkans and
south-eastern Europe. The Egnatia motorway is one of the first large-scale public
works to apply a system of environmental management, that is, a method of
organising and implementing environmental protection and mitigation measures
in the design, construction, and operation stages of the project. This covers
heritage protection, impacts on ecosystems, noise, waste, energy,
cleaning/maintenance/restoration, pollutant gases, and water.
Environmental BenefitsThe Egnatia motorway follows traces of the ancient Via Egnatia. Along its route
and within a 1,000m wide zone, 270 sites of historical interest have been
identified. Egnatia Odos S.A. protected all these, where feasible. The company
works with environmental organisations and scientists to minimise the
motorway impact on ecosystems and fauna. A monitoring programme
for noise is set up in residential districts; where necessary, appropriate protection
measures are applied. The concentration of pollutant gases is continually
measured - even in most of the tunnels; air quality management is a priority
- to protect quality of life and mitigate global warming. Skilled staff gather
and dispose surface waste, based on existing environmental legislation. Action is
taken to limit energy consumption, via: a programme of light measurements
and energy management in tunnels; a regular maintenance programme; a time-
schedule for lighting; limitation of electricity consumption based on timely
Egnatia Odos S.A. is the company responsible for the design, construction, operation, maintenance and exploitation of Egnatia motorway. Egnatia Odos S.A. also manages the design and construction of additional projects and has extended its activities abroad, by participating in international tenders and undertaking contracts for the management and supervision of designs and construction works, mainly of large infrastructure projects.

In 2007-2008, a part of the motorway E34 near Antwerp was rehabilitated with
a double-layered CRCP (continuously reinforced concrete pavement). The
original road pavement of 1977 consisted of concrete slabs, laid on a base of
lean concrete. Although the slabs were initially dowelled, serious step forming
originated at the joints. The road became very uncomfortable, particularly on the
right-hand lane carrying heavy traffic. In recent years there were also increasing
numbers of cracked slabs that had to be repaired. Even if the number of cracked
slabs remained within reason, general renovation became necessary because of
poor driving comfort.
The Roads and Traffic Agency (AWV) of the Flemish Government had drawn up a
list of potentially innovative applications for road-building. The use of recycled
aggregates in road paving was one of them. For this E34 renovation, it was
decided to apply two-lift concrete with recycled aggregates in the lower course.
Continuously reinforced concrete pavement was chosen, thereby giving the best
guarantees of a long and maintenance-free service life. The technique of
double-layered concrete or two-lift paving consists of dividing the concrete
pavement into a bottom lift of approx. 80 % of the total design thickness, and a
top lift of approx. 20 % of the total thickness. The thinner upper course makes it
economically justifiable to use fine, hard but also more expensive stones.
As a result, a high-quality upper course can be obtained with excellent safety and
driving comfort properties. Because the lower course does not reach the surface
the strict polishing resistance requirement no longer applies, and less noble and
cheaper aggregates can be used. This permits the use of recycled aggregates.
EUPAVE, the European Concrete Paving Association, was formed in 2007 to promote all cement and concrete products for transport infrastructure and to publicise to the maximum all technical information related to publications, studies, and worksite visits. The cement and concrete applications include: in situ cast concrete, concrete paving blocks, flags and other pre cast items, hydraulically bound base and sub-base layers, soil improvement and stabilisation and in situ pavement recycling. All transport surfaces are the subject of EUPAVE efforts - from motorways to bicycle paths and from airfield runways and railways to safety barriers and noise-reducing devices.

Maximising Sustainability in Concrete Road Construction
Environmental BenefitsAfter construction, the surface characteristics were
evaluated. The evenness, measured using a Longitudinal
Profile Analyser, was excellent with the exception of some
sections where, in the right-hand lane, the profile had to
match the level of the adjacent old hard shoulder. For the
coefficient of evenness CE 2,5 a maximum value of 35
is required, but 90 % of the results were below 25
and 70 % below 20. The skid resistance was checked
with the SCRIM. The transverse friction coefficient
must be at least 0.48. The results varied between 0.60
and 0.87 with 84 % of them above 0.70.
In terms of rolling noise, a reduction of more than 3
dBA was achieved with the two-lift paving technique
compared to the traditional single-layer exposed aggregate
concrete with a maximum aggregate size of 20 mm.

Eurovia developed GAIA as an environmental decision-making tool for use
by contracting authorities when evaluating the technical solutions proposed by
companies bidding on roadworks projects. Gaia uses recognised, published
European databases. The tool compares the environmental assessments of
different solutions for a given road worksite and utilisation. The system then
calculates the environmental impact of each solution. The impact categories used
to evaluate the solutions are taken from the French NFP 01-010 standard for
construction materials (resource depletion, GHG emissions, atmospheric
acidification, etc.) and from an additional list of "customised" impacts (for
example: local road transport (tonnes/km), excavated materials removed for
recycling, etc.).
Eurovia also created RECYCLOVIA®, an in-situ pavement recycling process
involving the use of a cold bituminous binder, emulsion or foamed bitumen. The
technique can be used to refurbish flexible and semi-rigid pavement surfacings to
a depth of approximately 150 mm.
TEMPERA® is a third current Eurovia product family with large potential.
TEMPERA® is a range of warm mixes that are produced and laid at
temperatures 30°C to 50°C below those of conventional mixes. The TEMPERA®
range is suitable for use in virtually almost all applications - wearing courses and
base courses - whatever the binder, modified and non-modified. Warm mixes are
suitable for all types of traffic, from motorways to urban streets.
Operating primarily in Europe and North America, Eurovia - a subsidiary of the VINCI Group - is a world leader in the construction and maintenance of transport infrastructure. Heir to a century of roadwork tradition, making the most of specialised expertise whilst driving innovation, Eurovia is supported by its 39,000 employees working in nearly 1,000 industrial and commercial entities in 14 countries. Eurovia's activity is centred on four complementary businesses: roadworks, materials production, quality of life developments and infrastructure-related services. Eurovia seeks to go beyond the traditional rôle of a roadworks company. It has developed new business approaches, providing more added value and technical content, meeting new needs voiced by customers and road users. Eurovia's dual ambition is to be the expertise benchmark in its business lines and the special partner of its contracting authorities.

Creating New Methods and Materials for 21st. Century Roads
Environmental BenefitsThe GAIA worksite environmental assessment tool now provides customers with a reliable environmental criterion that can
be used to support decision-making. Beyond the tables of results generated by the system for a given call for tender, the GAIA
tool enables both the roadworks company and the customer to ask the right questions in order to reduce
worksite environmental impact. Specifically, the tool makes it possible to systematically take global warming issues on
board and, for large projects, to make greenhouse gas emissions and resource conservation part and parcel of the
road structure design process. The RECYCLOVIA® process offers substantial environmental benefits: the process
requires no added aggregates; the technique offers energy savings of some 40%; a reduction of greenhouse gas
emissions by 20 to 40%; the worksite generates no waste; the use of a cold technique inherently limits the emission of
odours; there is limited disruption to the surrounding community. The TEMPERA® process is particularly suitable for
urban worksites since disruption to the surrounding community - odours, fumes, delays in re-opening the road to traffic -
during application are reduced. The absence of steam emissions also enhances safety for motorists driving near
worksites. The process lends itself to night work and worksites with long transport times, since the workability of the product
is maintained longer than that of a conventional mix. Over 700,000 tonnes have been laid since 2001. Performance values
measured in-situ have proven equivalent to those of conventional solutions, ensuring the durability of structures using these
products.

The ultimate goal of this tool is multifaceted:
- Performing a detailed environmental analysis
of road projects;
- Setting the stage for a comparative analysis of
various road-building techniques and
materials;
- Optimising the road construction site supply
scheme regarding raw materials providers,
choice of suppliers, delivery locations and
materials transport modes;
- Deriving a detailed estimation of GHG
emissions specifically ascribable to the road
construction industry.
The GHG is designed to be consistent, transparent, and credible in its coverage of emissions sources. It is fully
compatible with International Panel on Climate Change (IPCC) guidelines and the emission standards used are regularly
cross checked and validated. The basis module for road construction and maintenance will be completed with more
specific modules, such as barriers, road signs, ITS and waste. The IRF GHG Calculator tool is available for purchase in
electronic version and as a CD Rom. Updates will be regularly available.
The International Road Federation, in conjunction with a number of technical partners, has designed a methodology for
the calculation and modelling of emission estimates in carbon equivalency for road construction and maintenance
projects. The Greenhouse Gas Calculator aims to harmonise the procedure for calculating CO2 and other greenhouse
gas emissions from road construction projects, with a view to achieving energy savings and rationalising emissions data
reporting. This new tool provides an accurate, consistent and accessible inventory system for companies or
administrations measuring the GHG footprint of their projects. It is a vital addition to the inventory of cost-efficient
solutions.
The International Road Federation (IRF) is a nongovernmental, not-for-profit organisation with the mission to encourage and promote development and maintenance of better, safer and more sustainable roads and road networks. As a unique global platform bringing together public and private entities (from leading civil engineering companies and planners through to government ministries, public authorities, financial institutions and research institutes etc.), we are committed to disseminating timely information and global best practices to enhance knowledge as well as to offer expert knowledge, business opportunities and training.
Founded 60 years ago, the IRF is an important and recognised source of expertise and contacts. Its work is organised around a number of core activities, including notably, a comprehensive programme devoted to Environment. Since the beginning of 2009, IRF manages an important new project, the global Transport Knowledge Partnership (gTKP) a DFID (UK Department for International Development) initiated and funded project which offers a platform for improving road infrastructure and road transport in developing countries and transition economies through knowledge sharing and dissemination of recognised best practices around eight distinct themes, including Environment and Climate Change.

Environmental BenefitsSustainable roads can only be built by practitioners who are
fully aware of the environmental impacts of their activities,
as well as the possibilities for reducing this impact. The new
IRF GHG Calculator will enable this.
The tool is based on an input/output modelling approach.
The calculation model is composed of a simple set of
equations and enables estimating the total GHG emissions
(outputs) generated by each of the identified and quantified
emission sources (inputs). The calculations undertaken refer
to the full life-cycle of the road infrastructure and are
repeated for different scenarios and different construction
techniques. Three basic phases can be identified:
preconstruction, road construction and road maintenance.
Among the data collected, distinctions are drawn between
- The inventory of the emissions sources;
- Data and standards relative to the evaluation of these emissions sources;
- The database of emissions factors pertaining to the set of identified sources.
The calculator's output provides an incentive for innovation and advancement of current construction practices, aiming at
reducing emissions and generating corporate economies. In particular, it will help to identify intensive energy consumption
practices that can be replaced by more energy-efficient techniques and technologies.
The IRF would like to thank its technical partners for their valued assistance in the development of the Greenhouse Gas
calculator: 3M, Ammann Group, COLAS, EPFL, Scott Wilson, Volkmann & Rossbach.

Greenhouse gas emissions, especially CO2 emissions, are the main cause of
anthropogenic climate change. The transport sector is responsible for the highest
increase in greenhouse gas emissions. Within the EU-15 greenhouse gas
emissions rose by 26% between 1999 and 2004 (European Environment Agency,
2006). This development demands clear political decisions at both national and
European levels.
In this context congestion and traffic effectiveness are significant keywords -
because the European Commission foresees a growth of 55% in commercial
traffic and 35% in passenger traffic on European roads in the years to 2015. The
adverse environmental effects of the traffic must be diminished. In trying to do
this, it has to be recognised that upgrading of road infrastructure can be
ecologically limited in its effects and expensive. So traffic management comes
into its own.
Today traffic management consists of traffic lights, key information for the driver
about traffic conditions, and systems for influencing routes and road networks.
The goal for traffic management today is to control driving behaviour and choice
of vehicle, route and departure time. Road user charging can contribute to
achieving that goal. The most appropriate concept uses differentiated fees
according to the vehicles' emission class. An integrated road user charging
system based on GPS/GNSS and GSM/GPRS and DSRC technologies is the
most advanced and suitable solution.
The Kapsch Group was founded in 1892 by Johann Kapsch in Vienna. Its early activity consisted of manufacturing telephones and telegraphs. In the 1970s Kapsch entered the analogue railway communications business. In the late 1980s the company began developing as an international communications solutions group. In the early 1990s it entered the road traffic telematics business, through selective strategic acquisitions in Europe. Since 2002 that business has a worldwide dimension, through establishment of subsidiaries and through further acquisitions.

results of a study of urban road-user charging on travel behavior, the environment and the economy - Impact Analysis of
Urban Road-Use Pricing on Travel Behaviour, the Environment and the Economy. Reductions in travel times and traffic
volumes achieved by tolling lead to decreased congestion, fuel consumption, emissions, noise and traffic
accidents.
Another study published by the Austrian Institute of Economic Research investigated various measures that can be taken in
the transport sector, such as substantial improvements in public transport, road pricing, increases in fuel tax, and promotion of
bio fuels. Road pricing turned out to be the most effective measure in reducing CO2 emissions.

With a fleet of 7,000 buses and
coaches, Stagecoach Group, a
Michelin Fleet Solutions customer, is
one of the United Kingdom's largest
coach operators.
Michelin Fleet Solutions offers large truck fleets all-inclusive tyre management
services, providing the customer with numerous advantages: instead of buying
tyres, customers purchase travel mileage. Designed for large European and
North American truck fleets, Michelin Fleet Solutions is a full service offer that
includes tyre availability and supply, maintenance and monitoring to provide the
customer with streamlined management, budget control and improved
productivity. The "Fleet Solutions" system is based on the principle of the sale of
a service replacing the sale of a product. It features a new economic model
in which the invoicing unit is the mile or kilometre travelled. The market for this
type of offer is strong since transportation companies strive to focus resources on
their core business, particularly by outsourcing vehicle maintenance. Michelin
Fleet Solutions is a business model well adapted to the current era of high energy
costs. The virtuous circle of sustainable development is in place: top economic
performance goes hand in hand with a lower environmental impact for the
benefit of all.
Environmental BenefitsEnvironmental benefits accrue directly and via advantages for both the customer
and the company. Fewer materials and energy are consumed for more activity.
Tyre performance is optimized, thereby cutting fuel consumption. Fewer end-
of-life tyres need to be recovered, thus reducing energy use and other disposal
costs. Customers know their tyre budget up front and no longer fund their tyre
stock. Former fixed costs become variable costs and the rate of unscheduled
downtime time is reduced.
Michelin is at the forefront of all tyre markets and mobility-related service markets: its mission is to contribute in a sustainable way to progress in the mobility of both people and goods by constantly making travel safer, easier, more enjoyable, more economical and more respectful of the environment. The company in a nutshell: 131, 529 employees; a sales network covering 170 countries; 68 production sites in 19 countries; technology centres on 3 continents (Europe, Asia, North America); net sales of 16.9 billion

Preventive servicing makes it possible to reduce repair costs, thereby reducing the cost price of the service. Servicing time is
reduced - thanks to the preventive work carried out during maintenance, thereby improving vehicle productivity and
helping customers to focus on their core business. For Michelin, fewer tyres are manufactured for an equivalent or superior
activity, with more customers and a good loyalty rate. At the end of the day, the environmental impact of transportation
is reduced. Michelin Fleet Solutions key figures: more than 280 M in sales; more than 500 contracts covering more
than 300,000 vehicles; 850 Michelin employees dedicated to the activity, in 22 countries.

This project is but one example among many, of the work conducted by the
Agency. It is chosen because water assessment and management has not been
accorded its rightful place in the environmental pantheon until relatively recently.
Water management is now a leading concern of the World Business Council for
Sustainable Development, of the World Meteorological Organisation, of national
transport authorities and of academic research. With climate change, unusual
storm events are becoming increasingly frequent. Good design has to cope with
this, in addition to ameliorating the effects of normal run-off into sensitive
receiving areas; both surface and ground water, through better collection,
conveyance and treatment systems. But the starting point for any action has to
be evidence-based decision making.
The starting point for a recent assessment under the Stormwater Management
Programme of the Agency was that road water run-off was considered to
account for 40-50% of urban metal contamination to aquatic ecosystems. A
comprehensive study of vehicle kilometres travelled (VTK), VTK per catchment
area, VKT discharge to surface water, VKT discharge to groundwater and the
regional distribution of waterbody crossings by VTK was modelled for the
national state highway network. Analysis of this data led to identification of
estuarine hot spots in receipt of highway discharge from the Auckland road
network. Based on NZ data, the relative amount of vehicle contamination can be
differentiated from other sources by using a fingerprinting technique developed
from Grafton gully storm water tank which exclusively collects highway
discharge. Analysis of two dependent variables - vehicle-derived (zinc and
copper) and road-derived (polynuclear aromatic hydrocarbons, or PAH). PAH
sources include coal tar, exhaust and pyrogenic origins. Hopane, a steroid found
Not a company, but a Crown entity established in 2008, the NZ Transport Agency brings together the functions of Land Transport New Zealand and Transit New Zealand to provide an integrated approach to transport planning, funding and delivery. Working in partnership with regional and local authorities, the transport industry and communities, the NZ Transport agency is focused on delivering four key outcomes: integration, safety, sustainability and value for money. The Agency provides a vital link between government policy making and the operation of the transport sector.

in bacteria, is found only in bitumen. The ratio of hopane:
PAH is indicative of road-derived sediment from bitumen
surfaces.
Environmental BenefitsThe study showed that PAH concentrations from
predominantly road surfaces is significantly lower
than non-road derived PAH. Based on 50 samples from
five locations the contribution of zinc, copper and PAHs
to estuarine contamination may be much less than
that which was previously expected, when compared
to other urban sources.
Of themselves, such findings are not of immediate
environmental benefit. The benefit derives from the fact
that the relative amounts of contamination may be better
identified, as to source. Such identification is the
building-block upon which public policy, in terms of
any necessary amelioration, may be built. The study
will be expanded to a wider range of road conditions and
receiving environment to further develop the hypothesis.

Conservation of Energy by means of Intelligent Aquifer Utilisation Conservation of Energy by means of
Intelligent Aquifer Utilisation
Asphalt pavements have gained acceptance in recent years as an interesting new
renewable energy source. As asphalt pavements can heat up to 70 degrees
Celsius during solar irradiation, a comparison with solar hot water systems seems
obvious. Given the enormous area of asphalt pavement that is available, the
thermal energy potential therefore appears infinite. This heat can be utilized in
different ways. Generally the energy will have to be stored over seasons, for
example in an aquifer. Several designs have been developed to extract heat from
an asphalt pavement. Most available solutions apply a heat exchanger design by
incorporating tubes in the asphalt pavement. This type of asphalt pavement in
the Netherlands is known as ´asphalt collector´. Demand comes from buildings,
supply from the asphalt pavement. Through the use of an aquifer, the difference
in timing between seasonal supply and demand is covered to a large extent.
Environmental BenefitsIn addition to its energy potential, the advantage in using an asphalt collector is
the maintenance of the pavement. In summer time the maximum temperature of
the asphalt pavement can be reduced so that the chance of permanent
deformation is mitigated. In winter time, it is possible to avoid slippery roads by
increasing the minimum pavement temperature. Snow-free pavement is the
result, requiring no salt or other environmentally hazardous contaminants.
Though these additional advantages of the use of an asphalt collector may be
obvious, interest in such a collector is mainly focused on the energy potential and

the application of this energy in the built-up environment.
In terms of cost-effectiveness, this aspect is most
important. Thus, environmental gains with RES® include
less use of fossil fuel, reduced CO2 emissions and
elimination of use of salt on icy pavements, thus
reducing the environmental impact of salt or other
similar contaminants. These are among the reasons that,
since its introduction ten years ago, RES® has been
successfully applied in several road and airport projects in
the Netherlands, Belgium and Scotland - and there is a
growing interest and demand for the technology in the US
and China.

PB's Highway Sustainability Checklist was selected by the American Association
of State Highway and Transportation Officials (AASHTO) as the winning US entry
in the Sustainable Development category for the 2007 World Road Association's
(PIARC) International Competition. The checklist was developed in response to
growing interest in an objective, non-prescriptive, broad-based tool that would
support the integration of environmental stewardship practices and CSS into day-
to-day highway-related practices. The checklist is a compendium of possible
measures associated with various phases of highway projects-from planning to
design, through construction, operations and maintenance. It is meant to
facilitate decisions about the extent to which highway improvements might
incorporate measures that go beyond satisfying minimum functional
requirements by addressing contextual factors which contribute to sustainability
of the natural, built, and human environments.
Environmental BenefitsSustainability is as much a frame of mind as it is a body of technical knowledge.
The checklist is intended to be used not as a "mechanical" approach to
determining what would make a highway project more sustainable but rather to
instill a frame of mind by triggering questions that may otherwise be overlooked
and debate that might otherwise not occur. The idea is to plan, design, manage,
implement, operate and maintain highways in a way that does not simply avoid
or minimize harm (this is considered necessary but not sufficient) but creates net
benefits that transcend transportation functionality - benefits in terms of the
natural, built and social environments. The fact that so much highway work
involves improving existing facilities that were not necessarily held to the higher

The concept of 'green' roadways and buildings is sweeping the nation. The US
Green Building Council (USGBC) and its initiative for including green elements in
its construction projects is growing in importance for communities. In an effort to
become more environmentally friendly, every owner, engineering firm, and
construction supplier is looking for ways to use new 'green' concepts. Resource
International is at the forefront of this.
Environmental BenefitsThe City of Colorado Springs, Colorado is experimenting with a new pavement
method, Terminal Blend Tire Rubber Asphalt (TBTRA), on select roadways.
The goal was to not only create quieter and safer driving conditions, but also
provide the most durable surface while creating a more environmentally-
friendly atmosphere. After extensive research, the City learned that using
"wet" and "dry" tire rubber asphalt manufacturing processes led to excessive
smoke and aroma being released into the atmosphere at asphalt plants.
However, opting for the terminally blended manufacturing process proved to be
the most environmentally-friendly option. TBRTA is produced in a closed-system
plant, preventing smoke and particulates from entering the atmosphere.
In addition to being smoother, quieter, and safer-particularly during rainstorms,
the TBTRA has proven to have a significantly lower concentration of
roadway pollutants running into the roadside ditches compared to
contaminated stormwater runoff of other asphalt pavement.
Resource International, Inc. (Rii) has been operating since 1973 as a Female Business Enterprise in Columbus, Ohio. As CEO and Chair of the Board, Farah Majidzadeh built a company from the corporate HQ that began in her basement in 1973 into a broad-based, multi-disciplined, professional engineering consulting firm specializing in construction management, IT, and planning and design of buildings and infrastructure projects valued in excess of USD1 billion annually. Today, the Columbus-based corporate headquarters and its branch offices throughout the Midwest and abroad employ over 130 engineers and professionals and list a large roster of completed projects for federal and state government, education, healthcare and sports and entertainment. The firm has received consistent and widespread acclaim for its work. As one example - the Michael A. Fox Highway contract in Butler County, Ohio earned the IRF's Global Road Achievement Award and the American Road and Transportation Builders Association and Transportation Development Foundation's 2000 Globe Award for Environmental Excellence, the Build America Award for the Best New Highway in America, the Excellence in Concrete Paving Award in Ohio and the Quality Asphalt Pavement Award in Ohio. To date, it remains one of the only Ohio projects of its size to be completed ahead of schedule.

Five projects illustrate Scott Wilson's efforts to deliver sustainable road solutions.
They are: the A30 Bodmin to Indian Queens trunk road in Cornwall, UK; post-
consumer tyre rubber in rights of way and road surfacings; and two instances of
the use of hydraulically bound mixtures.
Environmental BenefitsThe A30 trunk road was a single carriageway with flows of 25,000 vpd, well in
excess of capacity. It also severed the Goss Moor National Nature Reserve, a
Special Area of Conservation protected under European Law. The objective was
to produce a solution which reduced congestion and improved road safety
whilst minimising the impact on environmental areas, all within the delivery
target of 5 years from award of the Early Contractor Involvement contract to
completion. The scheme has been commended as an example of cooperation
for the successful delivery of highways projects in sensitive environmental areas.
Continuous dialogue with stakeholders has driven the delivery of a solution
which enhanced and improved the environment.
Scott Wilson led two projects which explored the use of post-consumer tyre
rubber in rights of way and road surfacings. The first, a demonstration project,
involved the development and testing of a number of potential surfacings for
impact-absorbing rights of way. A bridleway in Nottinghamshire (UK) was
reconstructed using recycled rubber, recycled aggregate and quarry by-products.
The trial proved that the use of rubber provides a cost-effective and
durable alternative surfacing which is equally acceptable to cyclists,
walkers, and horse-riders, and can be applied in route maintenance or in full

Delivering The Right Highways Using The Right Materials
route reconstruction. This beneficial approach to using tyre waste has been adopted by the the rights of way
management sector and is being taken forward. The second project involved a desk study and a suite of laboratory testing
on Rubberised Asphalt (RA) to UK standards, using a range of UK materials. Consultation with industry experts for the
purposes of the study led to identification of information on the practical issues associated with RA for road
surfacing applications.
Recycled aggregates from construction and demolition materials (including highway arisings), and quarry by-
products, often perceived as waste material, can be used to manufacture Hydraulically Bound Mixtures (HBMs)
for a range of applications, up to and including base layers within major trunk roads and motorways. WRAP (Waste &
Resources Action Programme) commissioned Scott Wilson to examine the performance of HBMs in road construction and
trench reinstatement. HBMs can be mixed and placed using conventional paving equipment. They have the potential to
increase materials resource efficiency; they reduce demand for traditional primary materials; and they provide cost savings
over traditional primary aggregates. The use of HBMs for trench reinstatement is also the subject of a technical report
prepared by Scott Wilson. Following on from this work, Scott Wilson have undertaken in-situ compaction trials and produced
a guidance document on the use of recycled materials.

Many factors can contribute to traffic congestion. The most basic explanation is
that the number of drivers trying to use the same road is so high that it goes
beyond the road's capacity to handle cars. Unfortunately, the underlying reasons
for too many cars in one place at one time are complicated. University
departments and civil engineers dedicate hundreds of hours to understand how
traffic congestion forms and what can be done about it. The important thing is
to do what needs to be done - quickly. Very often, what needs to be done is to
change the number and availability of traffic lanes.
The QMB innovative system prevents tail-backs at motorway exits, allowing for
rapid movement of the safety barrier delimiting motorway deviations and lanes.
In the USA, the QMB System is used for both construction sites and fixed plant,
where the flow of commuter traffic is in different directions in the morning and
evening. The system involves a machine that shifts the barrier sideways at a rate
of 9 and 15 km/h. The barrier is made from shaped concrete elements very
similar, for example, to the New Jersey guard-rail. The top section is T shaped,
making it possible for the machine to lift barrier elements by a few centimetres,
thanks to a system of rollers that passes under the two side wings.
Snoline was set up in 1955 with the aim of finding a new, easy way to produce long-lasting road markings. The result was the pre-formed tape that today accounts for half the company's turnover, produced in its factory in Trezzo sull'Adda, on the Milan-Venice motorway, 20 kilometres from Milan. The company's mission is to improve road safety. To this end, other types of road marking, plastic and rubber products for lane separators, warnings for drivers and passive safety devices that reduce the consequences of impact with fixed obstacles, have all been developed.

Quickchange Moveable Barriers (QMB)
Environmental BenefitsReconfiguring the roadway to expand the work zone without permanently closing lanes accelerates construction and relieves
congestion. Using the movable barriers system during construction can: reduce congestion by adjusting traffic flow, reduce
accidents due to positive separation, increase work-zone size during off peak periods to increase contractor productivity,
significantly reduce overall construction time which leads to lower costs, reduce fuel consumption and, therefore, air pollution
and carbon dioxide emissions, avoid stress and frustration to motorists and avoid congestion on secondary roads

As a result of a "cradle-to-grave" life cycle analysis (using ISO 14040
methodology) of former traffic light and VMS generations, SWARCO FUTURIT
designed and developed a new traffic signal named FUTURA and a new
generation of VMS. The assessment considered raw material extraction,
processing into semi-finished product, production of finished product, use phase
(incl. energy consumption) and the end-of-life management. For the variable
message sign with a 4x3m freely programmable full-colour display, a use phase
of 10 years, a switch-on rate of 20% and an average brightness of 50% were
assumed in order to calculate energy requirements. For end-of-life management,
the recycling of metals and a thermal treatment of plastics - in accordance with
most European waste regulations - were specified. Since the LED module of the
FUTURA traffic light remained unchanged, efforts concentrated on simplifying
the housing design of the new signal head, with a significant reduction in
material inputs while not compromising the signal's stability. Material extraction
and emissions during the production and recycling phases were reduced, too.
For the VMS, major changes have been made to the sign housing, energy supply,
heating and cooling systems and the LED modules; surface mounted technology
(SMT) based printed circuit boards and components are used for the new
generation.
Environmental BenefitsExpressed in terms of global warming potential (GWP) the overall reduction
achieved by both new product generations compared to the previous ones is
around 60%. The environmental impacts arising from material consumption and
SWARCO, headquartered in Austria, is a growing international group providing the complete range of road safety and traffic management products, systems, services and solutions. As the world's largest traffic signal producer and the number two in reflective glass beads, SWARCO has comprehensive know-how in LED-based signalling technology and road marking systems with excellent night visibility. The group offers innovative solutions in adaptive urban and interurban traffic control, static and dynamic signage, parking, public transport priority, infomobility as well as road marking materials and contracting. A sound environmental approach has always been an important motivation of the Group and its business activities.

production are dominated by the production of the
housings. The optimisation of the housing and related
reduction in material demand for aluminium (VMS) and
polycarbonate (FUTURA) have significantly improved the
result for both phases. The improvements will benefit
SWARCO customers, particularly through reduced energy
needs during the life of FUTURA and the new VMS. But
the principal beneficiary of SWARCO FUTURIT's eco-design
initiative is the environment. The redesign of the variable
message sign will lead to a reduction of 25.5 tons of CO2
emissions over the VMS 10-year life cycle. To put this in
perspective - a modern passenger car emitting 160g of
CO2 per kilometre will have produced 5.5 tons of CO2
having travelled almost 160,000 km, equivalent to 4
journeys around the globe.

Long Island Sound is an estuary where saltwater from the Atlantic mixes with
fresh water from New York and Connecticut rivers. The Sound is 110 miles long
and up to 21 miles wide, and located in one of the most densely populated
regions of the US, with 10 percent of the nation's population living within 50
miles of its shores. Increasing development in the region has resulted in extensive
habitat degradation. Funded by a USD 35,000 grant from the National Fish and
Wildlife Foundation, 45 Transpo's EnviroSafe Modular Catch Basin Filtration
Systems were fitted into storm drains at Veterans Memorial Park in Norwalk CT.
EnviroSafe can be retrofitted to fit flat-grated, combination curb-grated catch
basins as well as curb only inlets. Comprised of a basin housing a filter cartridge,
the unit is mounted at the grate (the point of entry). The large basin traps debris,
while inside the cartridge, the modular construction includes open cell foam that
is treated with an antimicrobial shield. In addition to filtering sediment this foam
is highly effective against microorganisms like bacteria, fungus, and mold. The
subsequent layers incorporate coagulant-based and ion-exchange processes for
filtering hydrocarbons, oils, grease and heavy metals like cadmium, lead, copper
and zinc.
Since 1968, Transpo Industries of New Rochelle, NY, has manufactured and supplied "smart solutions" products for bridges, roads, tunnels, railroad crossings and airport runways. Their safety products and polymer concrete materials are widely recognised for quality and performance. As a long time provider of road surface products, the company has realised another growing demand - controlling storm water run-off. Unchecked growth of impervious surfaces is contributing to exponential increases in run-off volumes and pollutant loadings.

Keeping Run-Off Pollutants Out of Long Island Sound
Environmental BenefitsWhen the filters were cleaned after six months of operation, each filter had an average of 54 pounds of trash, or 15,000
pounds total. Norwalk has been testing influent and effluent for E. coli and oil and gas to determine the efficiency of the
filters and is happy with the quality of sediment removal. If the city can keep sediment from reaching the marina, it will
increase the amount of time between dredging of the harbour. Since the last dredging cost the city approximately USD
250,000, any extension of time between dredging operations is a money saver. The catch basin insert filters are the most
cost-effective solution because maintenance of the filters is a simple task. The time required to clean each filter is 10 to 15
minutes, which is considered quite acceptable. The filters have killed 80-90% of the bacteria that would have entered Long
Island Sound - obviating the need to close beaches and avoiding local shellfish. The various filters have captured the
equivalent of a major marine oil spill. The company has entered a partnership with local municipalities on a coastal education
centre, to teach the next generation the importance of the Long Island Sound ecosystem.

Amphibians - frogs, toads, salamanders and newts - are regarded by many
scientists as early indicators of ecosystem health. Their sensitivity to
environmental change make them one of the first organisms in an ecosystem to
show signs of damage to the broader environment. Amphibians also play a vital
ecological role by moving nutrients - in the form of their own bodies - from rich
aquatic habitats to relatively nutrient-poor adjacent areas. They also serve as a
crucial link in the food chain by eating insects and through being eaten, in turn,
by hawks and foxes, for example. Amphibians make periodic mass migrations,
particularly during their breeding seasons. At such times, local populations can
suffer 50-100% mortality rates from passing vehicles when they attempt to cross
even lightly travelled roads. The road industry has in recent years become aware
of the fact that it can safeguard amphibian populations through special fencing
and the provision of channelled road crossing points.
Environmental BenefitsVR amphibian rescue fences and channels provide safety for amphibians by active
protection with environment and landscape-friendly profiles. They have an
optimal price-performance ratio through use of patented construction kits
assembled by qualified personnel, adapting the products to any topography.
Typically, the animals are held back before they reach the road and then
channelled into tunnels connecting the different parts of their habitat. VR thus
helps to sustain natural species diversity and contributes to the environmental
sustainability of roads, even in natural and unspoiled areas.
Volkmann & Rossbach has contributed to road safety for more than 40 years. Its product range includes mobile steel barriers (such as MiniGuard® and VarioGuard®), guardrail systems, road marking (with paint, tapes, hot and cold plastics and agglomerates), amphibian-protection systems and under-ride protection for motor-cyclists.
VR is made up of different companies for manufacturing and service. They cover the entire range of business activities from product development up to installation, from project design to maintenance.

Amphibian Rescue Fences
The fence system
The Amphibian-Guard® guiding device consists of 400 cm long elements. The steel plates are hot dipped galvanized and so
have an average durability of over 20 years. The elements' height of 40 cm and the overhanging edge of 7cm makes the
system invincible for toads, frogs and also small mammals. The large bottom area forms a vegetation-free running surface that
channels the animals into safe crossing areas. The elements are fitted gap-free so that animals do not get trapped or try to
climb. An additional underground barrier makes it impossible to tunnel under the system. The system can be adjusted to the
topography both vertical and horizontal. The elements can be connected in any angle and so guarantee continuous
assembling even under difficult circumstances.
Additionally, Amphibian Guard® can be combined with a robust wire mesh fence that is invincible for larger animals like wild
deer or boars. This space saving solution protects animals of all kinds and sizes from accident with cars on open roads that
lead through their habitats.
Thus, VR Amphibian Guard® offers an easy, long-lasting and very efficient way to make roads friendlier to the environment.

One of the key causes of pollution and traffic congestion are unplanned incidents
including accidents. Reducing accidents and making our roads safer and
facilitating traffic flow are key elements in promoting efficiency and improving
environmental performance. Transport and travel by sustainable modes is almost
a cultural pre-requisite now, but one of the main challenges for transportation is
of balancing individual benefits with those of society as a whole. For instance
when considering Eco driving (increasing vehicle efficiency compared to fuel
usage). them most fuel efficient route (distance) might appear to be through a
town centre (particularly for vehicles fitted with automatic stop and go systems)
but the town bypass may be a road with fewer junctions and a speed-flow
profile that is much more fuel efficient. There is a risk that urban traffic systems,
or a traffic control room or even in-car systems, can adversely affect the road
users if traffic solutions do not factor in the human element. Often users
experience visual and cognitive distractions, mental overload and a reduction in
awareness of their surroundings. This of course can have negative connotations
for safety.
At WSP Group our global transport planning experts combine with our specialists in civil engineering, intelligent transport systems, and human factors to ensure that we develop and implement sustainable transport and information services and systems for our clients and their customers. Our Group approach to sustainable business operations is mirrored in the advice we provide to our clients to make best use of their, and the world's, global resources. Internally we have pioneered the development of car sharing software, innovative "smart working" initiatives, and working closely with community leaders to promote sustainable living in our local environments.
At WSP our combined approach includes the selective application of Intelligent Transport Systems (ITS) and Human Factors as a way to change behaviour by providing management and information to enable better decision making. The current generation of technology can be evaluated not with just a view to modify if need be but to promote new design ideas. This in turn facilitates next generations of technology that further enhance the safety of 'end' users. It is by understanding all aspects of transport and user behaviour that we are able to develop successful systems and services.

Combining Human Factors with Intelligent Transport Systems
Environmental BenefitsITS is helping to address many of today's transport issues by harnessing technology to make our transportation safer, more
efficient, easier to use and more environmentally acceptable. ITS provide greater returns when end users have confidence in
the information. There research and evaluating the human interaction with road technology or policy will improve usage,
acceptance and compliance with such systems.
Ultimately this will contribute to for more efficient and greener transportation based on knowledge and understanding.
