Abstract:

 Aiming at the traffic signal timing in oversaturted traffic conditions,a bi-level programming（BP） model for the area coordinated control of traffic signals is presented based on the dynamic subarea division,with the maximum total throughput and the minimum delay time of all entrance lanes at each interaction as the objectives.Then,the effects of queue length,entrance traffic volume and phase sequence on the area coordinated control are analyzed,and the constraint formulas describing the relationships among the intersection phase difference,the effective green time and the dynamic traffic volume are established.Finally,the proposed model is solved by using the hybrid optimization strategy of genetic and simulated annealing algorithms,thus improving the reliability and computational effi-ciency of the global optimal solution.Simulated results indicate that the proposed model accords well with the practical situation.
