Bus Punctuality Control Model Based on the Phase Margin Time at Intersections

Abstract:

To improve the bus punctuality rate, this study presented a method to control bus arrival time to the downstream bus stop by optimizing the upstream intersection signal timing scheme. The deviation between bus actual and scheduled departure time at the upstream signalized intersection was adjusted by introducing the intersection phase margin time, and the bus punctuality control model based on the phase margin time was established. The bus arrival scheduled timetable was generated via a comprehensive optimization of common cycle length and offsets along the artery. The simulation results show that the developed control model can guarantee the bus punctuality, and the bus timetable can get a good control effect.
