Reasonable Distance of Pedestrian Crossing Facilities for Road Sections

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.
