多时段可变导向车道设置与信号优化方法
|
摘要
提出进口道满足设置条件均需设置可变导向车道的假设,设计了一种各控制时段采用不同最优车道功能和信号控制组合方案的方法,使各控制时段交叉口的运行指标达到最优。以西安市友谊东路-文艺北路交叉口为例,采用该方法确定了研究时段的最优组合方案。仿真结果表明:优化方案能提高交叉口通行能力4.8%,降低车均延误10.4%,有效地提高了交叉口的运行效率,验证了该方法的可行性。
The hypothesis that variable inlet lanes need to be set for the inlet conditions to meet the set conditions is designed. A method of using different optimal lane functions and signal control combination schemes for each control period is designed to optimize the operation index of intersections in each control period. Taking the intersection of Youyi East Road and Wenyi North Road in Xi'an as an example, the optimal combination scheme of the study period is determined by this method. The simulation results show that the optimization scheme can improve the traffic capacity of the intersection by 4.8% and reduce the average delay of the vehicle by 10.4%. The efficiency of the intersection is improved and the feasibility of the method is proved.
