Abstract

Bus Rapid Transit (BRT) is a highly effective traffic mode to relieve urban traffic congestion. To improve the operational efficiency of the BRT, a new schedule optimization model for BRT is proposed by using minimizing the travel time as the objective, in which the schedule at each bus stop and the passive signal priority control at each intersection along the line are optimized simultaneously. A mixed-integer nonlinear problem model is formulated to capture real-world operational constraints. The model is solved by the nondominated sorting genetic algorithm. Extensive sensitivity analysis and case study results validate the promising effectiveness of the proposed model. The results show that more than 15% delay reduction can be obtained when the departure interval is more than 360 s, the traffic volume is less than 300 veh/h/ln, and the total number of nodes (including bus stations and intersections) is less than 60.
