摘　　要：公交串车优化主动性差会造成公交线路准点率低、乘客需求响应度差的问题.本文首先对公交串车的状态过程演化描述和公交串车防治手段进行了分析,提出1种基于自适应动态规划提出面向单路段的公交串车优化策略,实现了公交滞站、速度引导、信号调整3种手段的组合调度,最后经过仿真验证发现,能本文方法能使线路累计偏移降低76.83%,实现串车防治控制.The poor initiative in bus-bunching optimization can result in low punctuality rate of bus routes and poor response to passenger demand.This paper first analyzes the evolutionary description of the state process of bus-bunching and the means of bus-bunching prevention and control,proposes a bus-bunching optimization strategy based on adaptive dynamic programming for a single road section,realizes the combined scheduling of three means of bus dwell,speed guidance and signal adjustment.After simulation and verification,it was found that this method was able to reduce the cumulative line offset by 76.83%and achieve bus-bunching optimization.
