遗传算法在丁字路口信号灯配时优化控制中的应用

Application of Genetic Algorithms in the Optimized Control For the Allocation of Time by Traffic Light on T-shaped Road Junctions

建立了丁字路口交通流的动态模型 ,并利用遗传算法对丁字路信号灯配时进行实时优化。由实例仿真结果可见 ,该方法在交通分配不对称的情况下能实时修正各相位的配时 ,具有较好的控制效果。

A dynamic model of the stream on T shaped road junctions has been constructed in this article, and a real time optimized allocation of traffic time by the traffic lights on T shape road junctions has been achieved by means of genetic algorithms. Judging from the results of the simulation test based on real traffic conditions, we can ensure better arrangements of the optimized real time allocation system in multiphase traffic allocations.
