为了应对城市轨道交通网络化条件下的延误影响,提出基于线路间换乘运力协调的列车运行调整策略.通过上海轨道交通系统的多源运营大数据分析,得到运行延误对相邻线路列车间衔接关系和换乘站客流组成的影响规律,提出衔接调整策略和分流调整策略.结合相邻线路连接关系,考虑客流需求和站台能力约束,给出换乘运力协调方案的求解算法,并分析策略适用情况.实例验证结果表明,线间协调调整策略能够有效降低延误影响,优于传统的延误本线疏解方案,可为网络化运营条件下的延误管理提供解决方案.

Train Operation Adjustment Strategies in Metro Based on Transfer Capacity Coordination

In order to cope with the delay effect under the condition of urban rail transit network, the train adjustment strategies based on inter-line transfer capacity coordination is put forward. Through the analysis of the multi-source operation data of the Shanghai metro system, the influence laws of the train delay, on the relationship between trains of adjacent lines and the passenger flow composition of the transfer station, are obtained. And the linkage adjustment strategy and the diversion adjustment strategy are proposed. Based on the connection relation of adjacent lines, considering the passenger demand and the station capacity constraints, the algorithm of solving the transfer capacity coordination scheme is given, and the application of the strategies are analyzed. The numerical results show that the inter- line coordination adjustment strategies can effectively reduce the impact of delay, which is superior to the traditional single-line adjustment methods and can provide a solution for the delay management of networked operation conditions.
