This paper takes passenger waiting time cost and bus operation revenue balance as the optimization objectives and establishes a bus timetable optimization model with the constraints of bus full load rate and departure interval. Taking Nanning No. 26 bus line as an example for analysis, the optimized bus timetable is compared with the status quo bus timetable, the cost of passenger waiting time is reduced, and the bus operating income and full load rate are improved, which proves the feasibility of the model and algorithm.展开更多
