This model can minimize the total of waiting time of passengers and the running cost of school buses with several constrains including the passengers’ numbers and the longest endurance time. Moreover, the data from Wuhan University of Technology, used as an example, verify the feasibility of the model. At last, the whole results are calculated by the Particle Swarm Optimization.展开更多
