Abstract

Phase sequence and pedestrian cross pattern have significant impacts on the capacity of intersection. This paper concentrates on realigning a signal phase sequence to design a new pedestrian twice crossing (PTC) pattern providing additional time for pedestrians. To fully evaluate the operational performance of such an intersection with applying the realigned signal phase and the new PTC pattern, another two similar intersections with different signal phase sequences and cross patterns are established using VISSIM. One applies a typical 4-phase signal sequence∗, and pedestrians only can cross the street in vehicle-through phase. The other applies the same vehicle signal sequence as model 1, but pedestrians apply a normal PTC pattern to cross the street. Five indices such as vehicle average travel time (VATT), vehicle average delay (VAD), pedestrian average travel time (PATT), pedestrian average delay (PAD), and the number of vehicles and pedestrians crossing the intersection per hour are employed to evaluate the performance of these three developed scenarios. The simulation results show that three models have very little gaps in VATT, VAD and the number of vehicle and pedestrian crossing the intersection. The New PTC pattern, however, makes a significant progress in pedestrian PATT and PAD compared with other two patterns. © 2017 The Authors. Published by Elsevier B.V.
