What is FVD®®?What is FVD®®?

FVD units

ITIS developed the concept of the Floating Vehicle Data Unit based on vehicle mileage travelled and driving patterns, whereby:

–average driver = 1 FVD® unit, –a business driver = 3 FVD® units –truck/coach = 30 FVD® units.

Through selective mixing and statistical modeling it can be shown that the ITIS FVD system requires a smaller sample to provide high quality data.Ie. focusing on data collection on the busiest roads at the busiest times.

The combined fleet within the ITIS FVD® system is approximately 50,000 vehicles. To achieve this level ITIS targeted a number of high profile FVD® probe fleets, including:

 Annual mileage

FVD® Units

AA patrol > 100 million 31,500

National Express > 80 million 16,000

Eddie Stobart > 100 million 22,500

In addition to the above fleets ITIS signed data supply contracts with large telematics companies that track vehicles for logistics and fleet management purposes. ITIS also targets probe vehicles that may be required to increase data quality in a more localised urban or inter-urban area, such as a local haulage or taxi operators.

How did ITIS build an FVD network?

Unique technology featuresUnique technology features

• Travel time, not velocity. – The technology is based on extracting travel time information and not velocities from the supplied data. This

has the advantage of providing extremely accurate journey time information.

• Merging of historic and real-time data. – The system does not consider traffic information to be static but combines both historic and real-time traffic

information to generate accurate predictions of traffic congestion.

• Advanced GIS modelling. – Advanced GIS techniques are used to model the topology of the road network taking account of the

different turning options within a given network. This means the system can provide accurate traffic information in complex road networks such as dense urban areas.

• Data independent.– The technology is not dependent on any single positioning technology and can be adapted to take almost

any form of location information. The algorithms have been developed to cope with inaccurate locations and very noisy data to achieve the accuracy and comprehensive road coverage required to provide high quality traffic information.

• Data fusion. – Data can be fused from different information sources including mobile and static sensors and journalistic

data reports.

• Knowledge-based algorithms.– A series of learning-based algorithms have been developed which constantly update the historic traffic

patterns used within the system.

TELCO WAP/SMS

ITIS currently provide two WAP traffic services, for Vodafone Live! and Orange World.

Vodafone customers are able to browse for the latest traffic information directly from their handsets

as well as being able to request AA recommended routes complete with any relevant traffic delays.

Orange customers are able to receive constantly updated traffic flow information displayed in colour,

and can scroll up and down affected segments of any UK motorway to see a colour-coded scale that

shows current traffic conditions.

Text TRAFFIC to shortcode 82085 GetMeThere.co.uk will send you a map, via WAP push, showing current traffic conditions in the area you are located for only £1!

A web based application offering a number of travel and

traffic related services.

ITIS currently supplies web based traffic and mobile

based traffic services.

Traffic Reports

•  Fast desktop application•  All major UK routes covered•  Extra detail for UK traffic hotspots•  Traffic alerts updated every 10 mins•  Audio and visual alerts for     traffic incidents

Automotive

• RDS-TMC sends live, real-time traffic information to the satellite navigation system - automatically, 24 hours a day.

• Information is sent via an FM radio signal that can be received even if the car radio is switched off.

• This   constant supply of traffic  information enables the satellite navigation system to give the driver advanced warning of congestion and traffic problems ahead.

• More importantly, because traffic information is integrated directly into the satellite navigation system, the driver is automatically given the unique option to take an alternative route to avoid the problem ahead - dynamic route guidance, at the touch of a button.

• Available in two formats: – Free – RDS-TMC – Conditional Access RDS-TMC

Radio Data Signal – Traffic Message Channel

RDS-TMC

ITIS currently provides “free” RDS-TMC services to over

120000 customers in the UK for over 15 different vehicle

brands including:

•Toyota

•Lexus

•Ford

•BMW

•Mercedes Benz

•Nissan

•Vauxhall (GM)

•Subaru

•Porsche

•ITIS are also launching an GPRS/RDS-TMC service for

personal navigation devices:

Motoring organisations

Automobile association

• The AA is the UK's largest motoring organisation with over 12 million members.

• In May 2002 ITIS and Automobile Association Developments Limited, part of the Automobile Association (the AA) announced a significant strategic relationship.

• Under the terms of the deal, ITIS became responsible for supplying real time traffic flow information to AA Roadwatch, the leading provider of traffic and travel news in the UK.

• This relationship was strengthened in October 2002 when ITIS also became responsible for operating the AA's short dial IVR traffic information service under the AA Roadwatch brand, as well as providing real time traffic flow information to the AA's website.

• At the same time, the AA agreed to provide ITIS with location data from its AA patrol vehicle fleet, providing a valuable source of data for the ITIS Floating Vehicle Data system (FVD®).

Data Sources

• GSM– Advanced negotiations ongoing with two network operators.

• GPS– Outline access agreements to 2000 commercial vehicles agreed.

• Journalistic– Agreement in place with VicRoads

– Undergoing negotiations with RTA and Dept Main Roads of Qld.

– Agreement in place with major roadside assistance company.

• Mapping– Licence in place.

• Expect all initial supply agreements to be in place by Q4 2005.

Analysis platform and outputs

• Initial network analysis for CFVD to be undertaken by ITIS in the UK.

• Ongoing implementation to be undertaken by Traffic Intelligence in Australia.

• Data Centre (1) to be set up in Sydney• Data Centre (2) to be set up in Melbourne

• Expected to be output ready for– Melbourne by February 2006– Sydney by April 2006– All east Coast metro by July 2006– Australia wide by December 2006.

• Dependent upon customer funding

Conclusion

• Through the use of ITIS technology, by end 2006, Traffic Intelligence will be the ONLY national Australian provider of quality detailed real time and historic road traffic information generated through proven technology.

• This traffic information will provide:– Urban and rural travel times– Congestion indexing– Vehicle flow volumes– Origin/destination information– Network management and performance information– Incident information

• This information will in time be supplemented by videos of incidents (Drivecam)

• Due to the “imported” nature of the technology, Traffic intelligence is unable to access any state or federal grants to assist in implementation, so is keen to work with “foundation” clients.
