摘　　要：合理的确定城市轨道交通行车间隔时间是优化轨道交通运营调度方案的关键。在介绍列车开行间隔影响因素的基础上,根据客流在时间上变化的规律,从轨道交通乘客和轨道交通运营企业双方利益最大化出发,建立以乘客的等车费用、车内费用和运营企业变动费用总和最小为目标的轨道线路行车间隔非线性优化模型,并详细介绍了模型的构建和简化过程。最后用matlab对所给的算例进行了计算和结果的分析,证明了模型的可行性,得到了当行车间隔在(0,6.3]的范围内时,总成本是随着行车间隔的增加而减少,当行车间隔在(6.3,+∞]的范围时,总成本是随着行车间隔的增加而增大。Determining a reasonable headway time of urban rail transit is a key to optimizing scheduling schemes of urban rail transit. On the basis of introducing the influential factors of headways, a Single-rail nonlinear optimization model of headways which minimizes the total of the passengers＇ waiting costs, the passengers＇ costs on board and operational enterprise＇s variable costs is established from maximizing the interests of both passengers and operators according to characteristics of time about passenger travel. The process of establishing and simplifying model is described in details. Finally, a given example is calculated and analyzed by employing matlab, which proves the feasibility of the model. A conclusion is reached that the total cost will decrease while headway time which is within range from 0 to 6.3 increases and will increase while headway time which is within range from 6.3 to ＋∞ increases.
