Abstract: The proper and effective optimal model of the departing interval is the key to the dispatching scheme optimization and the bus service improvement. Based on the existing model and the alteration rule of the passenger movement, this paper has adopted the thoughts of handling the departing interval by the multi-objective assembled optimizations to build the model of departing interval on bus dispatch aiming at the minimal fee of the passengers and bus companies. The model has been applied to the bus demonstration route of Guangzhou based on the local bus surveying data and proved to be feasible.

摘要： 合理有效的公交车辆发车间隔优化模型是优化调度方案、改善公交服务的关键，因此，本文在分析现有模型的基础上，根据客流变化规律，对发车间隔采用分时段多目标组合优化处理的思想，建立了以乘客和公交企业运营费用最小为目标的公交车辆调度发车间隔模型，并采用广州市公交调查数据对该模型进行了验证，实验表明该模型可行。
