| 摘 要： | 在分析现有信号交叉口控制算法的基础上,提出一种基于petri网的信号交叉口控制方法,此方法基于一典型信号交叉口的混合petri网模型,采用遗传算法,对信号配时进行优化。用M atlab对方法进行编程和仿真,得到最优配时方案,结果显示此算法可一定程度上减少交叉口延误,有较好的实际应用效果和通用性。

| Abstract: | This paper proposed a method of signalized intersection control based on Petri net and genetic algorithm after analyzing the existing control strategy.The method optimizes signal timing strategy with genetic algorithm based on the hybrid Petri net model of a typical signalized intersection.Then we program and simulate the method with Matlab and achieve the optimal signal timing strategy.The result show the method can reduce intersection delay in a certain extent and achieve good practical effect and universal application. |
