Integration of Dynamic Route Guidance and Traffic Control System

Cel

Infrastructure based dynamic route guidance systems will provide valuable information for the traffic control authorities and in turn information from traffic control systems will be required by the guidance system in order that its routing advice is appropriate. This project's goal is the integration of the dynamic route guidance and traffic control systems (TCS).
The project CAR-GOES, for the past 3 years, has been investigating the integration of infrastructure-based dynamic route guidance (DRG) systems with existing forms of urban traffic control (UTC). The performance of different levels of integration have been studied, principally by simulation, for various types of dynamic route guidance, ranging from centralized to distributed (but excluding systems where route optimisation is performed in the vehicle), as well as various types of urban traffic control, ranging from fixed time to traffic responsive. Some attention has been given to multirouteing, which would be required with increasing rates of market penetration. The prediction of link travel times has been looked at, and the need for dynamic assignment coupled with the estimation of origin destination flows, particularly under high market penetration scenarios, has been pointed to.
Research within CAR-GOES has led to recommendations and designs for integrating centralised and decentralised DRG systems with a range of UTC systems used throughout Europe, and has illustrated the benefits which can be obtained. A range of strategies have been formulated for various levels of integration, based primarily on existing forms of UTC but allowing for new forms of DRG. The performance of some strategies have been studied by simulation for various levels of penetration.

The work is split into four work areas:
A. deals with the state-of-the-art in TCS and route guidance systems with a view to the new data exchange requirement. It includes an analysis of established TCS and DRG (Dynamic Route Guidance) by all partners. On the basis of this Work Area A creates the framework for the rest of the project. Input from various other DRIVE Tasks will be required, e.g. advanced parking control, road pricing systems.
B. concerns strategies for dynamic guidance and driver information systems and route optimization techniques. It will specify, develop and simulate strategies and algorithms appropriate for an integrated TCS & DRG environment.
C. will establish specifications for a common roadside infrastructure based integrated guidance and traffic control system. The work will include:
- a review of the existing systems to establish the starting situation;
- an investigation of the requirements of the various actors and user groups to determine functional requirements and constraints;
- a recommended system design and specifications for implementation.
D. covers the implementation aspects and recommendations for a series of field trials.
