Abstract
This paper describes how microscopic traffic simulation is used to determine the network effects of traffic information. A route choice model is developed and applied that simulates the route choice decisions of individual drivers, both pre-trip and during the trip, based on the traffic information received by the drivers. The results are presented in terms of total travel time in the network, and in terms of individual travel times. Conclusions are drawn about route choice model and about the advantages of in-car traffic information and dynamic route information panels (DRIPs) and compared to a situation without traffic information.
