| 摘 要： | 提出了基于改进粒子群优化的关联交叉口协调控制方法。建立了关于排队长度的交通流模型和协调控制目标函数,利用改进粒子群算法对各交叉口绿信比和考虑双向绿波的相位差进行求解,实现了关联交叉口的最优控制。以实际采集的几个关联交叉口的交通数据仿真表明,相比单向绿波控制和感应控制,所提方法可有效减少延误和平均排队长度。

| Abstract: | This paper proposed a coordinate method for relative intersections based on improved particle swarm optimization.The traffic flow model of queuing length and control object function were built.The signal split and the phase offset were optimized by improved particle swarm optimization.The simulation result shows that the method is an effective and practical method,which can effectively reduce delay time and shorten queuing length. |
