Comfortable application has been one of the popular research topics in ITS recently. In this thesis, we propose a dynamic Traffic-Signal Control method and a vehicle-based intelligent routing method to increase the efficiency of the vehicle transportation. And the proposed scheme is explored in a real road topology and vehicle mobility model to investigate the routing performance.
The car-following model, include the driver’’s behavior, is based on the speed limits and the safety distance headway to adjust the speed. Therefore, it can better simulate the real traffic flow. Then, we use Webster equation to design the traffic signal cycle, and decide the time intervals of traffic light according to the flow condition. Finally, an intelligent routing method is based on the pre-scheduling number of vehicles to predict the speed when arrive at the target segment. And then, use the predicted traveling time on each segment to determine the routing path according to the Dijkstra’s algorithm. The simulation results show the performance of proposed method and the shortest path algorithm especially in the heavy traffic load.
