【摘要】 针对信号交叉口行人和机动车对配时要求不一致以及我国行人相位清空时间不足的问题,借鉴HCM的做法给出了行人绿灯最小时间和行人闪时间的计算公式.根据是否将绿灯间隔时间作为行人清空时间,研究了行人随机动车一起放行时的行人相位和机动车相位的设置类型,探讨了不同类型的适用情况,建立了不同情况下行人绿灯时间的调整模型和行人信号配时方法,并进行了实证分析.改善了信号交叉口传统配时方法对行人重视不够的问题.更多还原

【Abstract】 The pedestrian timing at signalized intersections was studied aiming at the problems of the inconsistency of the vehicular and pedestrian timing requirements and the insufficiency of pedestrian clearance.The formulae of WALK indication(WALK) and Flashing DON’T WALK indication(FDW) were presented profiting from HCM.The relationship between pedestrian signal indications and vehicular signal indications was discussed according to whether the vehicular intergreen interval was composed in pedestrian clearance interval when pedestrians were discharged with vehicles at the same time.The applicability of every case was discussed.Then,models of the pedestrian green adjustment and methods of pedestrian timing for different cases were established.An example illustrated the application.The study pays more attention on pedestrians.更多还原
