Optimization of Network Signal Timing Based on Dynamic Traffic Guidance

Under the condition of dynamic traffic guidance, the path selection behavior of divers would results in the new road network traffic condition, and then the influence of traffic flow on network signal timing optimization must be taken into account in the process of matching. This paper presented the scheme of network signal timing, and then the algorithm of integer programming and mountain climbing was used to optimize the network signal timing in dynamic traffic guidance. At each research point, the path equalization was carried out to make the calculated target function - the road network performance index. At last, this algorithm was used to calculate the road network instance, and the results showed that the proposed algorithm could optimize the scheme of equalization network signal timing.
