The invention discloses a traffic signal coordination control system based on VISSIM, relates to the technical field of intelligent traffic, and solves the technical problem that the predicted vehicle driving behavior is inaccurate due to the fact that the driving psychology of a driver is not analyzed when the time length of a signal lamp is optimized according to the actual road condition in the prior art. According to the method, the vehicle driving behavior at the current intersection is predicted, the condition that the driver starts to decelerate when reaching the psychological safety distance is predicted, the vehicle driving behavior can be predicted more truly, and a coordination optimization scheme of the signal lamp can be more accurate; according to the method, the weight coefficient of the intersection is obtained by calculating the number K of vehicles capable of passing through the intersection, the effective green light duration of each intersection is obtained by combining the proportion of the weight coefficient of the intersection with the signal lamp period, and the signal lamp duration is optimized according to the effective green light duration. The obtained signal lamp coordination optimization scheme is more reasonable, and the vehicle passing efficiency can be improved.
本发明公开了一种基于VISSIM的交通信号协调控制系统,涉及智能交通技术领域,解决了现有技术中在通过实际道路状况优化信号灯时长时,没有分析驾驶员驾驶心理而导致预测的车辆驾驶行为不准确的技术问题;本发明通过对当前路口车辆驾驶行为进行预测,预测驾驶员在到达心理安全距离时开始减速,能够更加真实的预测车辆的驾驶行为,能够使得对信号灯的协调优化方案更加准确;本发明通过计算能够通过路口的车辆数量K来得到该路口的权重系数,通过将路口权重系数所占的比例与信号灯周期结合,得到各路口的有效绿灯时长,根据有效绿灯时长对信号灯时长进行优化,使得到的信号灯协调优化方案更加合理且能够提高车辆通行的效率。
