Abstract: A method was provided for setting the minimum bus headways in order to solve the high-frequency of bus operation with the target of realizing the minimum operation costs and maximum benefits of passengers based on description of high-frequency of bus operation and analysis of the causes． This model has been applied to the No． 81 Route bus in Chengdu by surveying data and proved to be feasible and effective．

Key words: high-frequency of bus operation, minimum departing interval, operating costs, passengers’traveling costs

摘要： 在分析公交列车化现象及其产生原因的基础上，从考虑约束发车间隔下限出发，以缓解公交列车化现象为约 束条件，以公交企业运营成本最小和乘客利益最大为目标函数，探讨了公交车最小发车间隔的确定方法。用成都市 81路公交车调查数据验证了该模型的可行性和有效性。
