摘要:
轨道交通市郊线连接了郊区与中心城区，乘客出行具有比较明显的时空分布不均的特征。对市郊线快慢车的开行比例进行优化研究可以有效解决乘客滞留，节约运营成本。以灰色预测模型为基础，通过历史客流数据预测未来短期各时段内的客流量。根据预测的客流值，建立市郊线某工作日各时段开行比例的优化模型，并使用分支定界法进行求解，并以上海轨道交通16号线为例进行了线路开行比例的优化研究。可以为市郊线快慢车开行比例的确定提供参考。
Abstracts:
Suburban railway links the central city area and suburban areas, but passenger travels on the suburban railway appear obvious uneven spatial-temporal distribution. The study on suburban speed-to-slow train ratio optimization could effectively solve the detention of passengers and save the operation cost. Based on the gray forecasting model, the historical passenger flow data are used to predict the future short-term traffic in different time periods. On this basis, an optimization model of the opening suburban train proportion on a certain day is established according to the predicted passenger flow value, then the branch and bound method is adopted to solve the problem. Finally, Shanghai rail transit Line 16 is taken as an example to carry out a study on the line opening ratio optimization, which could provide a reference for the determination of suburban speed-to-slow train proportion.
