摘　　要：结合传统的方案生成式和方案选择式交通控制方法的优点,提出了一种基于启发式搜索和反馈修正的单路口控制方法.在对交通流的实际控制中通过搜索-反馈修正的过程寻找最优方案,并利用反馈修正监控和应对交通流的时变.最后通过两组仿真实验,证明了该方法的控制效果优于定时和感应控制,并且具有对初始参数和人工维护依赖小,适应性强的优点.We raise a traffic signal control method for isolate intersection based on heuristic search and feedback correction by combining ideas of the decision-generating traffic control methods and the decision- selection traffic control methods. The method searches the optimal control strategy by heuristic search and feedback correction in the practical control procedure. It can also detect and manage the change of the traffic flow dynamics through feedback correction. We verify the method by two kinds of numerical simulation experiments, the results show that our method is better than fixed-time control and actuated control, and it also has an advantage for it needs few initial configurations and manual settings.
