  • In order to study the influence of traffic guidance information on driver's behavior, the causes of traffic congestion shift under real-time guidance were analyzed from the aspects of guidance proportion, the number of alternative routes, the rationality of alternative route and the traffic distribution of road network, three methods were proposed to prevent from congestion shift, which included escalating guidance proportion, adding disturbance to linkcost data and providing K alternative routes to driver, and the methods were evaluated and compared by using traffic simulation software named Vissim.Simulation result shows that in a road network with local congestions, the methods have the ability to alleviate or eliminate congestion shift, the performance of providing K alternative routes is the best; the performance of escalating guidance proportion is the second; although the performance of adding disturbance to linkcost data is the third, it is much better than the conditions of completely guiding driver and adopting no guiding measurement.
