Optimal Layout of Bus Rapid Transit Stops at Intersections Based on Delay Analysis

Abstract:

In order to enhance the operation efficiency of the bus rapid transit (BRT) system, the optimal layout of BRT stops at intersections was discussed. Theoretical models were established for estimating the delay and queue length at the end of the green time with the consideration of signal control delay, dwell time and the waiting time for boarding and alighting service. Two scenarios of BRT stop locations, near side and far side bus stops were taken into account. The models were tested by VISSIM simulation. Results of extensive numerical analysis show that the position of the BRT stop has no effect on delay when the volume of BRT vehicles is low and the bus stops should be disposed at the intersection approach when the volume is high.
