Abstract:

In order to improve the critical volume conditions of pedestrian signal, the delay model of no signal branch road section under condition of the equal right of way for pedestrians and vehicles was built. Moreover, the partitioning standards of pedestrian group and the calculation method of conversion coefficient of pedestrian crowd and vehicles were put forward. Based on that, the arrival rate of pedestrian crowd was converted to the arrival rate of vehicles, and equilibrium phase delay formula was used to calculate the delay of signalcontrol branch road section. The critical volume curves of pedestrian signal for branch road section were obtained by comparing the delay under branch road section condition with or without traffic signal.

Key words: engineering of communications and transportation system, branch road section, pedestrian signal, conversion coefficient, critical volume curve
