Mutual Influence Research on Crossing Pedestrians and Moving Vehicles on Major-Street in TWSC Intersections

Typical configuration of two-way stop-controlled intersection is a four-legged intersection, where the major-street is uncontrolled, while the minor-street is controlled by stop signs. The aim of this research is to study the effects of crossing pedestrian volume on the delays that major-street’s vehicles experience when yielding to pedestrians. The intersection boundaries for a two-way stop controlled (TWSC) intersection analysis are assumed to be that of an isolated intersection. In this study, sample data with moving vehicles’ arrival time, departure time and pedestrians’ waiting time and crossing time are analyzed with statistics theories. Firstly, crossing pedestrians are divided into two types, including without causing vehicles’ stop and with vehicles’ stop. Analysis results show that these two types have different performance, for example, first type of pedestrians always walked slower than second type of pedestrians. In the other way, stopped vehicles on major-street because of yielding to crossing pedestrians at intersections are classified three types, such as “Active Yielding Vehicles”, “Following Stopped Vehicles” and “Passive Stopped Vehicles”. These vehicles experienced different stop delay because of “before (related to arrival time) or after” relationship with crossing pedestrians. Usually, stop delay of “Passive Stopped Vehicles” are lower than others. Lastly, interval times of vehicles for crossing pedestrians are analyzed, showing that no vehicles experienced stop delay with more than 12 seconds of “P/V Interval”. Some “before” vehicles would choose to be “Active Yielding Vehicles” before a crossing pedestrian arrived at the intersection, because the drivers saw the pedestrian earlier in front of stop line. The results of this research can be used in operational analysis to obtain realistic estimates of TWSC intersections’ capacities taking into account the impact of pedestrian crossings.
