基于遍历剪枝算法的干线绿波协调控制参数自动计算系统

针对当前交通干线绿波协调控制参数求解过程复杂、计算耗时较长等不足,基于遍历剪枝算法和SVG技术,构建由干线参数配置、绿波时距图展示、绿波参数自动计算模块等组成的干线绿波协调控制参数自动计算系统。并选取无锡市梁清路4个交叉口进行测试应用,实地验证系统的可行性。应用测试结果表明:该系统能够大幅简化干线绿波协调信号配时参数的设置流程,提高配置干线双向绿波协调参数的实施效率。

AUTOMATIC CALCULATION SYSTEM OF TRUNK LINE GREEN WAVE COORDINATED CONTROL PARAMETERS BASED ON TRAVERSAL PRUNING ALGORITHM

Aiming at the shortcomings of the current traffic trunk line green wave coordinated control parameters, such as complex solving process and long calculation time, we constructed an automatic calculation system of the trunk line green wave coordinated control parameters based on traversal pruning algorithm and SVG technology, which was composed of trunk line parameter configuration, green wave time-distance map display and automatic calculation module of green wave parameters. We selected four intersections of Liangqing Road in Wuxi City for testing and application, and verified the feasibility of the system on the spot. The application test results show that the system can greatly simplify the process of setting the timing parameters of the trunk line green wave coordination signal, and improve the efficiency of implementing the two-way green wave coordination parameters of the trunk line.
