Abstract: This paper analyzed the running characteristics of vehicles and pedestrian under different crossing conditions by studying the three conditions of pedestrian crossing including crossing freely, crossing in non-signalized crosswalk and crossing in signalized crosswalk. Vehicles delay was studied under the three conditions on the assumption that the arrival gap between pedestrian and vehicle obeys negative exponential distribution and the calculation method of delay under different condition is described. The result indicates that, selecting appropriate crossing mode for pedestrian can decrease vehicle delay effectively, especially when the traffic of pedestrian and vehicle is heavy, setting crosswalk (including signal control and non-signal control) can greatly decrease vehicle delay.

Key words: vehicle delay, pedestrian crossing, crosswalk, signal control
