摘要
针对行人斜穿信号交叉口的实际过街需求,利用时距图分析了不同信号相位相序设置和行人过街组织方案的运行效果,提出了行人连续横穿信号交叉口的绿波带设计方式。根据行人到达和离开位置点的时刻线,推导了行人沿顺时针、逆时针以及不固定方向连续过街的延误模型,建立了总的行人连续过街延误模型通式。算例分析和仿真试验结果表明:本文提出的行人连续过街延误模型能够准确计算行人斜穿信号交叉口的延误时间,获取最佳的信号相位相序和行人过街组织方案,从而实现了行人连续过街的绿波通行,减少了行人连续过街的延误时间。
Considering the real demand for pedestrian diagonal crossing at signal intersection, the operation effects of different signal phase settings and pedestrian crossing organization schemes were analyzed using the time-space diagram. Then, a design approach of pedestrian green wave for continuously crossing signalized intersection was proposed. According to the pedestrian arrival and departure time, the delay model of pedestrian continuous crossing along the clockwise, counterclockwise and unfixed directions were deduced. Finally, the general delay model for pedestrian continuous crossing was established. The results of case study and simulation show that the general delay model can predict the delay of pedestrian diagonal crossing accurately. This model can also help to acquire the best signal phase sequence and pedestrian crossing organization scheme. Therefore, the green wave can be obtained and the delay of the pedestrian diagonal crossing can be reduced.
