Comparing Driver Information Systems in a Dynamic Modeling Framework

Abstract

A modeling framework is developed to assess the performance of driver information systems. The two main components of the framework are a route choice module and a traffic simulation module. In the route choice module, three types of driver information systems are studied: the pretrip information service, the in-car route guidance system, and the variable message signs. The traffic simulation module controls the dynamics in a road network as traffic evolves over time in response to driver information. The dynamic properties of the framework are demonstrated in a test network and a simplified Singapore road network. The results suggest that there could be an optimal level of subscription to driver information or market penetration. Subscription to real-time driver information services is recommended, but a high level of subscription may result in extra delay. Variable message signs are not as effective as either pretrip information or in-car route guidance at their respective optimal levels of market penetration.
