| Abstract: | To find the optimal layout of bike rental stations,from the aspect of residents＇ travel demand and traffic facility supply,the current characteristics and existing problems of the usage of public bike are analyzed.Then a bi-level programming model combined of self adaptive genetic algorithm and the combined feedback modal-spilt assignment model is built to solve the problem.The optimal layout plan can minimize regional travel cost and the construction cost of public bike system.A case is used to test and verify the practicability of the model.The result shows that the model can effectively solve the layout problem of bike rental stations and can offer suggestions for related planning. |
