动态更新相序和时长的交通灯智能控制算法
Intelligent Traffic Light Control Algorithm Based on Dynamic Phase and Time

针对现行的固定配时交通灯控制系统的相位绿灯时长固定和同相位不同方向车辆通行时长差异大的弊端，本文提出了动态更新相序和时长的交通灯智能控制算法，基于交通路口流量信息，通过实时计算优先相位和关联相位产生一个当前状态下的最优控制方案来调整交通灯的相位和相序，改变相位的绿灯时长，从而避免了固定配时方案下的空等现象，提高了道路的资源利用率。
As the disadvantages of the fixed timing traffic light control system, such as the fixed phase and traffic duration in different directions vary in the same phase, this paper proposes an intelligent traffic light control algorithm that dynamically updates the phase sequence and duration. Through real-time calculation of priority phase and correlation phase, an optimal control scheme is generated to adjust the phase and phase sequence of traffic lights, and change the green light duration of the phase, so as to avoid the empty phenomenon under the fixed timing scheme and improve the resource utilization of road.
