The invention discloses a signal control intersection pedestrian signal advance phase setting method. The method comprises the following steps: S1, deducing a pedestrian-vehicle conflict number estimation model according to a pedestrian-vehicle interaction mechanism and a probability theory; s2, constructing a pedestrian-vehicle conflict delay model and a traffic comprehensive delay model according to a pedestrian-vehicle random arrival distribution theory and a traffic flow theory; s3, constructing an intersection pedestrian signal advance phase comprehensive cost optimization model by introducing unit safety cost and unit efficiency cost and combining the pedestrian-vehicle conflict number estimation model and the traffic comprehensive delay model; and S4, solving the model by taking the pedestrian signal advance time and the green light time of each phase as variables according to the change of the pedestrian traffic flow at the intersection so as to determine the pedestrian signal advance phase setting condition at the intersection. According to the method, the influence on the running efficiency of the intersection is reduced to the maximum extent while the safety of pedestrians crossing the street is improved.

    本发明公开了一种信号控制交叉口行人信号提前相位设置方法,包括:S1、根据人车交互机理和概率论推导出人车冲突数估计模型;S2、根据人车随机到达分布理论和交通流理论,构建人车冲突延误模型及交通综合延误模型;S3、通过引入单位安全成本和单位效率成本,结合人车冲突数估计模型和交通综合延误模型,构建交叉口行人信号提前相位综合成本优化模型;S4、根据交叉口人车流量的变化,以行人信号提前时间和各相位绿灯时间为变量对模型进行求解,以此确定交叉口行人信号提前相位设置条件。根据本发明,提升过街行人安全的同时最大限度降低对交叉口运行效率的影响。
