A Simulation Study of Multiple Routes Guidance System in a Road Network

Traffic congestion has been a serious problem in urban road networks. The dynamic route guidance system is regarded as an important strategy in relieving the congestion.This paper discusses on the effectiveness of the dynamic route guidance system. First, we propose the route choice model and the traffic flow model for simulation analysis. Secondly, we propose the simulation framework to evaluate various types of dynamic route guidance in a large scale road network. Simulation results show that the multiple routes guidance is better than the dynamic shortest route guidance in high system penetration rate because of autonomous dispersions of each vehicle.
