| 摘 要： | 根据相邻路口间相互关系,利用混杂自动机模型确定路口信号周期单元,利用道路车流运动模型确定2个相邻交通路口的信号延时参数,并提出了一种信号灯优化策略来协调控制方案。在此条件下,寻找相邻交叉路口信号灯在动态交通条件下的最佳轮转次序和最佳绿信比。仿真结果表明,此方法可以有效地协调两相邻路口的红绿灯信号,在一定程度上改善了路段的交通状况。

| Abstract: | Traditional traffic control algorithms have been focused on isolated road intersections.However,this paper proposed a new optimization scheme for traffic signal based on the estimated interaction of two adjacent intersections.The hybrid automata model is applied to determining the signal cycles,therefore,the offset parameter can be determined by using vehicle travelling model.Under such circumstances,an optimal switching scheme and optimal order of phases of traffic light in dynamic traffic conditions are f... |
