Flexibility of scheduling and operation are important factors of bus rapid transit (BRT). Determining the headway and routes combinations according to the travel demand is the key in schedule optimization of BRT. This paper analyzes the existing model and establishes optimal mathematical model for BRT scheduling. This helps to determine the optimal bus headway and routes aiming to minimize the total travel time of passengers and operating costs of BRT. A genetic algorithm (GA) which applies two-dimensional 0–1 coding to represent pass-by stops sets and frequency was designed to solve the problem. Different schedule is determined by one-point crossover of GA. Finally, the model and the algorithms are illustrated as B1 of BRT in Guangzhou. Paramics-based simulation and evaluation results show that the method can improve BRT scheduling optimizing efficiency.
