Abstract

This paper outlines the requirements of simulation for modelling DRG (dynamic route guidance) and describes the enhancements made to the CONTRAM traffic assignment model for this purpose. These include new assignment strategies for unguided drivers, to reflect route choice "inefficiency" and their reaction to traffic incidents, separate assignment strategies for guided vehicles (e.g. based on LISB techniques) and facilities for analysing different levels and use of the DRG network. Evaluation criteria have also been extended. Sample results from the modelling are discussed. In particular, typical journey time savings for guided and unguided vehicles, and for the overall network, are illustrated for variations in the proportion of guided vehicles, the guided vehicles assignment, the DRG network available and incident characteristics. Much of the development and testing of the model has been undertaken outside of DRIVE, with the current use of the model to develop control strategies being undertaken in V1011.
