• Overview of Gauteng Freeway Management System (FMS) – ITS Extent in Gauteng

• FMS Functional Areas

• Challenges/Lessons Learned

• Future Initiatives

• Way Forward

INTELLIGENT TRANPORT SYSTEMS (ITS) BACKGROUND

• Historically, road authorities like SANRAL responded in supplying infrastructure in meeting growing traffic demands

• There’s been a Shift in the traditional/conventional approach towards a Network Management and Operational focus with emphasis on Network Optimization by effectively utilizing existing capacity

• Internationally referred to as the “Big Shift” from a Road Construction Only focus to an integrated approach of Road Network Optimization and Road Construction

• This Optimization is realized through cost effective and smarter Traffic Management, Traveler Information and Incident Management strategies

• This refocus is consistent in developing sustainable transportation networks, critical to economic success and at the same time being environmentally sensitive

GAUTENG OVERVIEW • This refocus is consistent and aligned with SANRAL’s vision and mission as an

implementing road authority.

• Severe traffic congestion is experienced on the Gauteng Freeway Network with sections of the network having: – Traffic flows between 100 000 180 000 ADT – More than 6000 vph per direction – Peak periods extending to 3hrs – Average speeds of 2050km/h

• These factors negatively impact • Quality of life • Running vehicle costs • Stifle economic growth • Environment (air quality) • Productivity

• The cost of congestion is too great to ignore and the implementation of Intelligent Transport Systems (ITS) is a cost effective means to optimize existing road infrastructure and manage congestion.

GAUTENG OVERVIEW

• Sanral implemented the 1 st Freeway Management System (FMS) officially launched by Minister of Transport, Hon. Jeff Radebe – October 2006.

• Aim of FMS: – Improve Road Safety – Manage & optimise Traffic Flow – Reduce Delays due to recurring and

nonrecurring congestion – Inform road users with timely &

accurate traffic conditions – Coordinate traffic operations

amongst roleplayers through the application of ITS strategies

ITS network extent: 200 km of freeway network

• N1 Western Bypass from N12 to Buccleuch • N1 Buccleuch to N4 east Donkerhoek • N3 South Buccleuch to Heidelberg • N12 southern bypass from N1 to N3 • N12 east from N3 to Snake Road • N17 from N3 S to Rondebult Road • M1 & M2 (JRA)

FMS components comprise of:

• Traffic Management Centre (TMC) • Fibre communications backbone • 220 CCTV cameras • 60 Variable Message signs (VMS) • Tactical Signs • Ramp Metering • Shoulder Lane Control • Inductive loops – ORT data (future)

KEY FUNCTIONAL AREAS

CONCEPT OF OPERATIONS

INCIDENT MANAGEMENT USE CASE

GAUTENG FMS FOCUS • Current FMS largely focuses on managing

and improving workzone challenges. These include implementation of :

1. ITS TRAVELLER INFORMATION STRATEGIES

2. ITS CONTROL STRATEGIES

3. ITS INTERVENING STRATEGIES

Persons in our Work Zones are at a high RISK of being killed due to exposure to the construction environment

Challenge is applying ITS strategies given the

environmental constraints to improve Safety within work

zone?

Applying ITS strategies to better communicate/ inform

and calm user fears?

FMS DELIVERY

Direct liaison with dispatching units Coordinated, structured response to incidents Reduce unnecessary & duplicating dispatch

Coordinate traffic operations amongst agencies

TRAVELER INFO

CONTROL

INTERVENING

FMS STRATEGY

Disseminate information via VMS, website, e mail, sms

Inform Road Users with timely information

Control inflow through ramp metering Manage throughput through Shoulder Lane Control Implementing Advisory Speed Control

Manage Traffic Flow

Prompt detection of incidents through visual, detector surveillance Inform, Warn, Regulate through VMS, tactical signs

Manage Incidents

Incident Management to reduce the incident timeline and occurrence of secondary incidents Identify Hazlocs based on accident trends and identify safety improvement measures

Improve Road Safety

FMS DELIVERY OBJECTIVE

CHALLENGES/LESSONS LEARNED SUBTASKS

Needs to be a shift from a Design/ Construct to Operate/ Maintain Regime – Often, opening a TMC is the catalyst to shift and focus on operations. – Requires shift towards performance monitoring and customer service,

Involve appropriate stakeholders in planning & development to ensure buyin, collaboration & establish clear operational roles from the onset

Identify an ITS Programme Champion & Coordinator to drive ITS programme –To overcome separate “silo” mentality in public agencies

Keep public/ media informed of aim & benefits of ITS strategies

• Institutional

• Agreements, MOU, SLA

• Awareness & Outreach

• Media Coordination

LEADERSHIP & PARTNERSHIPS


Realize that stakeholder policies, standards, systems are critical to ensure consistency in an integrated system

Understand the issues, user needs their priorities, strategies, tradeoffs that motivate agencies in partnering

Plan your system to accommodate future enhancements & expansion applicable hardware & software

Within this category limitations exist in skills & expertise in developing institutional requirements

• Architecture

• Policy, Standards

• Concept of Operations

• System Requirements Development

• Performance Monitoring

POLICY & PLANNING


Rapid deployment of field devices Use of standards based technology ito communications protocols (NTCIP Based Devices) State of the practice technology ito field equipment

Adopt Systems Engineering Process for traceability, verification & validation against high level requirements

Anticipate project delays, allocate sufficient time & funding to address key project variables; i.e electrical wayleaves, contaminated chips in hardware, theft etc)

Study areas of topographical encumbrances and radio interference when deploying wireless communications, consider vertical/ horizontal alignment, line of sight, radio frequency interference & latency issues

– Project Management

– Requirements & Design

– Standards & interoperability

– Quality assurance & Testing

– Design Tools & Models

DESIGN & DEPLOYMENT


Ensure accurate, timeous & reliable data to road user and external roleplayers – Critical in maintaining system and agency credibility

Build & strengthen relationships/ partnerships with public safety agencies – Capitalize and build relationships around triggering & special events to coordinate and manage operations

– Presidential Inauguration, IM Simulation test readiness, GFIP work zones, CONFED cup, 2010 FIFA World Cup

Operations manual and clear procedures is a key tool in leveraging effective operations. – Operational procedures lend consistency to daytoday activities, improve interagency working relationships;

– Establish effective communication protocols – Develop Performance measures, which brings accountability – Use available datasets to interpret & monitor system performance, don’t wait to collect “perfect” data

– Sound Information Leads to Sound Decisions – When You Measure, Measure Like You Mean It – Measure Where You Can, Model Everything Else

Data Accuracy, Data Storage

Operational Procedures

Performance Monitoring

MANAGEMENT & OPERATIONS


Consider long term operations & maintenance responsibilities & costs

–System maintenance, monitoring, and security procedures improve resource utilization, this increases system availability & reliability

ITS deployment is complex & may be subject to changes in technology and market forces (shipping delays, custom clearance)

Find innovative funding resources to finance operations

Partnering/ Commercial opportunities exist with private sector to share/ fuse data

–Data collection, analysis and warehousing procedures & policies support facility performance improvements and planning efforts.

•Agency

•Interagency

•Private

•Innovative Financing

FUNDING


Evaluate project by level of complexity & risk to determine appropriate ITS procurement package

Use appropriate procurement methods when outsourcing operations, maintenance & security support

Design ITS procurement process to ensure best outcome for vendor selection & performance

Procurement methods needs to consider growing local industry with the view of stimulating competition in local market in both consulting and contracting services to manage risks

Method of Award

Type of Contract

Performance/ Outcome Based/ SLA

Competition

PROCUREMENT


Develop written policies to address Liability Issues

Develop written policies to address Privacy Issues

Develop a formal ITS sharing policy for your agency

Protect data privacy by implementing user authorization levels for sensitive information

Privacy

Rules & regulations

Disputes & Claims

Intellectual Property Rights

LEGAL ISSUES


Ensure that staff resources and leadership capabilities are commensurate with scope and complexity of operations

Anticipate the need for Training, develop a training plan addressing short & long term training needs.

Select training & documentation methods which match operational objectives. Limited or lack of skills development initiatives and partnerships with tertiary institutions to develop focused ITS training curricula

TMCs often don’t provide a clear and progressive career path for personnel.

Compounding this problem is the highstress work environment & the shift from conventional working hours to a 24/7 environment

Recruiting & Staffing

Retention & Turnover

Training

HUMAN RESOURCES

FUTURE INITITIATIVES • INSTITUTIONAL

– Developing SANRAL ITS (all regions ) institutional requirements

– These key institutional requirements will develop a vision for the SANRAL ITS programme

– This will establish a strong institutional foundation to coordinate inter agency efforts in a coordinated and focused manner to build on the investments to date providing SANRAL the opportunity to better manage the transportation network nationally

– To provide the user with a single integrated system ito Traveler Information

FUTURE INITIATIVES

Implementation of 10 satellite service centres distributed along network (12 min. response time) to address and improve enforcement & Incident Management

• Intend partnering private sector in delivering service

Improving INCIDENT MANAGEMENT through:

• Deployment of Incident Response • Incident Recovery Services

Improving ENFORCEMENT MANAGEMENT through:

• Deployment of dedicated freeway enforcement unit

• Services will be managed by the NMC utilizing:

• Computer Aided dispatch (CAD)

• Automated Vehicle Identification (AVI)

• Automated Vehicle Location (AVL)

FUTURE INITIATIVES cont. Dedicated freeway enforcement unit

First Responders: Incident Response Service

Incident Recovery Service

ENVIRONMENTAL CHALLENGES

WAY FORWARD • Coalition building is amongst transportation agencies, private sector, and the public

to effect change and mitigate congestion is key.

• A transition needs to occur from a public works mentality to a mobility service mentality. A transition of this magnitude requires leadership driven by Policy leaders & buyin and the will of decision makers.

• Network Operations needs to be defined and institutionalized in agencies’ planning policies, in their processes and in their programs.

• This new focus will require a customer performance point of view rather than just a facilities performance point of view.

• Establishment of performance measures will be required. This action necessitates interagency consensus, collaboration and cooperation.

• Network Operations needs to be considered an essential part of a funding and staffing continuum that also include planning, design, construction and maintenance.
