摘要: 引入行人过街等待容忍极限时间作为信号配时优化的约束条件之一,提出了线控路段上交叉口之间人行横道信号参数的信号协调控制优化方法.该方法先以两相邻交叉口共红时间作为行人过街绿灯时间,当共红时间不足时,利用路段机动车车队的离散性和流率关系建立延误函数,以机动车在人行横道处造成的总延误最小为目标求解配时优化参数.结果表明,该方法保证了行人过街的安全性,降低了行人延误.

Abstract: This paper proposed the traffic signal optimization method for the midblock street crosswalk between coordinated adjacent intersections which introducing the pedestrian waiting tolerance limit time as one of the constraints of the signal timing optimization. The method takes the common red time of the two intersections as the crosswalk’s green time at first. If the common red time is not sufficient for the pedestrian crossing safely, it builds delay functions by using of motorcade dispersion and traffic flow rate relationship, and works out timing optimization parameter whose objective is to minimize the total vehicle delay. The result shows that this method may ensure the pedestrian crossing safety and reduce the pedestrian delay.
