A Study of Warrant for Staggered Pedestrian Crossing

Green time of pedestrian crossings on wide roadway is usually long due to corresponding pedestrians' crossing time. Especially, where a crosswalk is placed at an intersection at which minor roadway with a low traffic flow rate and major roadway with a high traffic flow rate cross, right-of-way for minor roadway is allocated more unnecessarily for the low traffic to provide minimum green time for pedestrians. A staggered crossing is used where length of crosswalk is too large. A staggered crossings can be also used for reducing delays of vehicles at intersections by giving different green phases to pedestrians directionally and allocate green times to vehicles of major roadways efficiently. This research describes a method to calculate delays of vehicles and pedestrians, and shows criteria to install staggered pedestrian crossings for some traffic conditions.
