摘要
文中提出了面向出口车道数不足交叉口的信号控制优化方法.考虑交叉口几何尺寸、分流和合流车辆对驶离流率的影响,基于多输出高斯过程回归分析了驶离流率的变化.考虑驶离流率的变化特征,构建了以车均延误最小为目标的初始信号配时模型;并以当前和下一周期车均延误最小为目标建立绿灯补偿模型.结果表明:相比于对照方案,优化方案的车均延误减少7.72%~10.84%,冲突次数减少71.42%~75.00%.
An optimization method of signal control for intersections with insufficient exit lanes was proposed.Considering the influence of intersection geometry size,shunting and merging vehicles on the departure flow rate,the change of departure flow rate was analyzed based on multi-output Gaussian process regression.Considering the changing characteristics of departure flow rate,an initial signal timing model with the goal of minimizing the average delay of vehicles was constructed.The green light compensation model was established with the goal of minimizing the average delay of vehicles in the current and next cycle.The results show that compared with the control scheme,the average vehicle delay of the optimized scheme is reduced by 7.72%~10.84%,and the number of conflicts is reduced by 71.42%~75.00%.
