路段行人过街设施的合理间隔

Reasonable Distance of Pedestrian Crossing Facilities for Road Sections

通过对路段行人过街设施的合理间隔进行分析,发现如果路段行人过街设施间隔过大,会导致行人绕行距离过长,行人乱穿道路的现象加剧;如果过小,则车辆行驶时频繁启停,行车延误增大。以行人延误和机动车延误之和最小建立目标函数,求解得到行人过街设施的合理间隔。路段行人过街设施的合理间隔与行人交通量、机动车交通量、路段长度以及行人过街宽度有关,充分考虑行人过街设施设置的各种影响因素。路段行人过街设施依据合理间隔进行设置,可以有效降低行人和机动车延误。

The reasonable distance of pedestrian crossing facilities for road sections is analyzed.If the section of the distance of pedestrian crossing facilities is too long,it will make the pedestrian bypass long distance.As a result,the phenomenon of pedestrian crossing irregularly will be aggravated.If it is too short,vehicles will start and stop frequently,and thus delay will be increased.Based on vehicle delay and pedestrian delay,the minimum objective function is established.The objective function is solved and reasonable distance of pedestrian crossing facilities of road sections is obtained.The reasonable distance of pedestrian crossing facilities of road sections has to do with the volume of pedestrians and vehicles,length and width of road sections.Therefore,full consideration should be given to the impact of various factors of the design of pedestrian crossing facilities.If the distance of pedestrian crossing facilities of road sections is set up reasonably,it will decrease the delay of pedestrians and vehicles.
