随着我国城市轨道交通网络的不断扩大、推动高质量发展的需求，对网络化运营组织水平都提出了更高的要求。对于不具有越行条件的线路，如何通过优化列车停站方案来提高列车运行速度，是一个重要的研究方向。在对传统A/B跨站停运营模式优劣分析的基础上，提出了通过开行A/B/C三类列车可同时实现列车运行速度的提高以及所有乘客无换乘。首先，基于可乘坐列车类型对OD进行划分，对各类型客流占比、可乘坐列车概率以及出行时间进行了探析。构建了以跨站方案和发车频次为决策变量的混合整数规划模型，并设计遗传算法进行求解。最后，以北京地铁六号线为例进行算例分析。算例结果显示，A/B/C跨站停运营模式下乘客无需换乘，总出行时间和在车时间可分别减少2.15%和6.79%。若不考虑等车时间，总在车时间可减少14.25%。

With the rapid development of urban rail transit and the need to promote high-quality development, higher requirements have been put forward for the operation and organization level. For the lines without overtaking facilities, it is important to improve the train speed by optimizing the train stopping plan. Based on the traditional A/B skip-stop mode, this paper proposes A/B/C skip-stop mode to achieve time-saver without transfers. Firstly，the characteristics of all trips under various stopping patterns are investigated, and an mixed integer programming model with stopping patterns and frequencies as decision variables are constructed. Additionally, a genetic algorithm (GA) is developed based on the model. Finally, the effectiveness of the proposed model and heuristic algorithm is verified through a set of real-life instances based on the Beijing Metro Line 6. The results show that the travel time and in-train time can be reduced by 2.15% and 6.79% respectively without transfers. If taking no account of waiting time, the in-train time can be reduced by 14.25%.
