随着我国城市轨道交通网络的不断扩大以及高质量发展要求，对网络化运营组织提出了更高的要求。对 于不具备越行条件的线路，如何通过停站方案优化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 3 类列车可同时提高列车运行速度且所有乘客无换乘的 方案。首先，基于可乘坐列车类型对 OD 进行划分，对各类客流占比、所乘列车占比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 6 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 at the operational and organizational levels. For 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 an A/B/C skip-stop mode to achieve a time-saver without transfers. First, the characteristics of all trips under various stopping patterns are investigated, and a mixed-integer programming model with stopping patterns and frequencies as decision variables is constructed. Additionally, a genetic algorithm was developed based on this 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 the waiting time is not considered, the in-train time can be reduced by 14.25%.
