| 摘要： | The bus network design problem refers to a determination of optimizing the network of bus routes, usually in urban areas. The optimal routes must comply with a given passenger demand matrix and attain a compromise best solution from the user, the operator, and the community. This paper proposes the use of a genetic algorithm as a tool to handle the complexity of the bus network design problem. The methodology developed considers a mechanism to maintain as many satisfactory routes of the existing network as possible and, at the same time, to incorporate experience-based suggestions, such as minimizing of the number of transfers required by a passenger, into the revised bus network. The solution method, using genetic algorithm, has four steps: (1) generating a set of potential routes, (2) designing the bus network, (3) checking the routes for implementation, and (4) examining the extension of routes for improvement. The proposed method is validated through a benchmark bus network and a case study. The result of the case study, with a bus network serving a city with a population of 3.2 million, shows an improvement of 26.36％ in the objective function value over the existing bus network. This improvement was realized by modifying only 36％ of the routes while the remaining 74％ of the existing network remained intact. |
