Abstract: In the study of customized bus planning for non-real-time response, the network planning of passenger direct-arrival of single-origin-destination and single-type is emphasized, while the development of diversified line operation mode is often neglected. Based on the planning theory of conventional bus, the Vehicle Routing Problem(VRP)is referred and the operated characteristics of customized bus are combined. Then this paper constructs the network design model of customized bus in diversified operation of multi-origin-destination and multi-type vehicle and passengers mixed load. Besides, the genetic algorithm is applied to improve the coding rules and to solve the multi-objective combinatorial optimization problem. Finally, an example is used to analyze the method. Compared with the conventional bus, the average stop number is reduced, the full-road ratio is increased, the average travel time is shortened, and the average travel speed is improved. The result shows that the model can get the ideal line operation schemes. The research results enrich the operation mode of customized bus. In the expansion of passenger travel demand coverage, the new method increases the flexibility of the vehicle deployment and line integration. At last, the research can effectively improve the demand response of passengers and the enterprises’ benefit.
