| 摘 要： | 分析传统交通信号控制系统中周期时长优化存在的问题，为适应混合交通自适应控制系统进行区域或干线战略控制和战术控制的需要，构建了基于双层规划的信号周期时长优化模型，借助分层迭代的思想，通过改进粒子群优化算法求解双层规划模型。利用Vissim仿真长春某一实验路网的不同交通状态，对模型和算法的有效性进行对比验证。

| Abstract: | Based on the analysis of traffic signal cycle optimization method in convention traffic signal control system,a model of the signal cycle optimization based on bi-level programming was established so as to adapt strategic and tactical control in area or arterial coordination control in mixed traffic adaptive signal control system.By the idea of the hierarchical iteration,a modified particle swam optimization algorithm was put forward to solve the bi-level programming.Finally,VISSIM was used to simulate diff... |
