摘　　要：周期化运行图列车开行模式指“相同种类的列车以固定周期间隔到达、出发或通过运行途中各车站”的模式,目前中国高速铁路除部分线路开行少量带有周期性质的整点大站停列车外,周期模式的应用尚处于起步阶段,缺乏针对周期模式优化设计的定量研究。旨在根据各线路运营条件和客流特点,研究合理设定周期长度和周期化水平的方法。建立整数线性规划模型求解基于不同周期长度的列车开行方案,以最少的列车方案线数量为最多的客流OD提供直达服务,提出周期化水平、客流直达率、换乘时间等周期模式评价指标的计算方法,对沪宁城际铁路及京沪高速铁路开展实例研究,验证模型的有效性。为有效解决周期模式特别是关键参数周期长度的定量优化提供了方法。The train operation mode of cyclic timetable means that trains with same stops arrive,depart or pass through stations on their way at regular intervals.Currently,its application in high-speed railways in China is still in its infancy,with the exception of some lines operating a small number of cyclic trains stopping at high-class stations on the hour.Quantitative research is inadequate on optimal design of cyclic operation mode.This paper aims to study the method of reasonably establishing the cycle time and cyclic level according to the operation condition and passenger flow characteristics of each line.An integer linear programming model was established to solve the train line plan based on different cycle time,to provide direct service for the most passenger flow ODs with the least number of train lines.The calculation methods of cyclic operation mode evaluating indicators,including cyclic level,direct rate of passenger flow and transfer time,were proposed.Two case studies of the Shanghai—Nanjing intercity railway and Beijing—Shanghai high-speed railway were carried out to validate the effectiveness of the model.The proposed approach can effectively solve the quantitative optimization problem of cyclic operation mode,especially the key parameter of cycle time.
