Signal Control Model for Mid block Pedestrian Crossing with Consideration of Downstream Intersection

Abstract:

In order to deal with the confliction between the safety of the pedestrian crossing and the efficiency of the vehicle traffic on urban arterial, this paper proposes a method for signal designing of mid block pedestrian crossing, which provides an appropriative signal phase for the pedestrian by using the red time of the vehicle at downstream intersection. The method is formulated as a mixed integer linear programming. The control objective is to maximize the duration of green for pedestrian on the basis of ensuring the safety of the pedestrian crossing and maintaining the efficiency of the vehicle traffic in status quo. The effect and the maneuverability of the control method are tested by VISSIM simulation and case study. Results show that in the case of successive crossings, the pedestrian crossing can be located at anywhere of the road section and the suitable signal timing can always be made. And in the case of non stop crossing, the designing of the location of pedestrian crossing and signal control should be considered synchronously.
