在车辆基地发车能力逐渐成为提高早高峰正线运营水平的瓶颈、部分城市开始探索建设ATC车辆基地的背景下，针对现有收发车能力计算方法难以应用于ATC车辆基地的问题，进行ATC车辆基地咽喉区通过能力计算方法研究以弥补上述不足。在ATC灭灯模式下，本文通过比较得到不同列车发车顺序下的最小列车总发车时间，进而计算得到ATC车辆基地的最大咽喉区通过能力。选取广州萝岗车辆基地为案例，分析结果表明，本文方法能够有效求解ATC灭灯模式下车辆基地的咽喉区通过能力，为评估车辆基地设计方案提供数据参考。对比分析结果表明，ATC灭灯模式能够大幅提高车辆基地早高峰发车能力，更好地满足早高峰正线的运营需求。

Under the background that the departure capacity of depot has gradually become the bottleneck to improve the operation level of the main line in the morning peak, and some cities have begun to explore the construction of ATC depot, aiming the problem that the existing calculation method of vehicle sending and receiving capacity is difficult to apply to ATC depots, the throat area capacity calculation method of ATC depots is studied to make up for the above shortcomings. Under the ATC light-off mode, compared with the total train departure time in different train departure sequences to obtain the minimum total train departure time, and then the maximum throat area capacity of the ATC depot is calculated. Guangzhou Luogang depot is selected as a case study. The case results show that the method presented in this paper can effectively solve throat area capacity of the depot under the ATC light-off mode and provide data reference for the evaluation of the depot design plan. The comparative analysis results show that the ATC off-light mode can significantly improve the morning peak departure capacity of the depot and better meet the operation requirements of the morning peak line.
