Conception et application d'un modèle de l'information routière et ses effets sur le trafic

Abstract : Traffic conditions on a road network often suffer from congestion. According to sources, the traffic congestion can be classified into two categories : recurrent congestion determined by the physic laws of traffic and non-recurrent congestion due to incidents, accidents or other hazards on the road. Thanks to the advancement of technologies, including computers, communications and data processing, the traffic operator is now able to detect disturbances, to measure the effects and even to anticipate traffic conditions to better match traffic management activities. Dynamic information on traffic conditions enables users to reduce discomfort and make their route choice decision more reasonable. For the operator, the service user information may be used as a traffic management tool. We investigated the potential contribution of dynamic traffic information for the benefit of individual users and system performance by taking into account : i) recurring congestion and non-recurring ; ii) different route choice behaviours based on accessibility to information service ; iii) other traffic management actions taken by the traffic operator. A theoretical model with an analytical application on a simple two-parallel-road network, an origin-destination pairs and two user classes, respectively-informed or non-informed has given many conclusions : i) an excessive distribution of traffic information with a « neutral » content damages both the individual profit and system performance ; ii) traffic information with some « cooperative » content may help optimize the system performance without causing acceptability problem ; and iii) dynamic information and other traffic management tools interplay in a complementary manner to optimize the traffic
