交叉路口中一种智能的车辆实时调度算法

针对城市道路交通拥堵问题,提出了一种基于智能交通信息环境下的车辆实时调度算法。该算法在现有信号相位设计的基础上,根据当前道路的相对滞留率进行相位的选择,然后针对每个被选中相位,调整交叉路口的交通信号周期,尽可能使更多车辆在各自车道上安全行驶。实验结果表明,提出的算法的车辆平均等待时间低于现有算法。...

Summary:针对城市道路交通拥堵问题,提出了一种基于智能交通信息环境下的车辆实时调度算法。该算法在现有信号相位设计的基础上,根据当前道路的相对滞留率进行相位的选择,然后针对每个被选中相位,调整交叉路口的交通信号周期,尽可能使更多车辆在各自车道上安全行驶。实验结果表明,提出的算法的车辆平均等待时间低于现有算法。

This paper proposed a vehicle real-time scheduling algorithm under the intelligent transportation information environment to resolve traffic congestion in modern cities. At first,it selected traffic signal phase according to relative backlog rate on the basis of the existing design of the signal phase. And then,it adjusted traffic signal cycle at intersection for the being selected signal phase in order to move vehicles as much as possible without traffic collision. Simulation results show that this algorithm has lower average waiting time than previous works.
