摘要： 在城市轨道交通首班车接续关系中，不存在两交路无法接续的情况，仅需考虑等待时间。因 此，客流分布规律、服务水平对首班车的发车时刻编排具有决定意义。通过分析首班车衔接优化研 究的重要性，提出将各个换乘方向的换乘客流量作为权重定量衡量首班车协调层次的方法。以列车 运行组织、换乘站到发时刻等为约束条件，以首班车乘客加权换乘等待时间最小化为衔接优化目 标，建立首班车衔接优化模型。利用遗传算法思想，运用MATLAB对模型进行求解。最后，以北 京市部分地铁线网为例验证了模型的可行性。

Abstract： The first trains of two crossing lines of urban rail transit can be always connected to each other. All that matters is the waiting time. Therefore, the distribution of passenger flow and level of service is significant to the scheduling of the departure time of the first train. By analyzing the importance of research into optimizing the connection of the first daily service, this paper proposes a method in which the passenger flow at different transfer directions is used to quantitatively weigh the coordination level of the first train. Based on the constraint conditions of railway transportation management and the arrival and departure time of transfer stations, the paper develops a model of first daily train' connection to minimize the weighted waiting time and transfer time of passengers on the first train. Using the principle of genetic algorithm, the model is solved by MATLAB. Finally, case studies conducted in several subway lines in Beijing are presented to demonstrate the model application.
