The invention relates to the technical field of intelligent transportation, and discloses a railway cross-line passenger flow hub train running method, which comprises the following steps of: constructing a rail transit service network model, constructing a cross-line passenger flow joined train stop scheme mathematical model, establishing double-target planning of a parallel relation, forming a double-target nonlinear optimization model, and only considering a single target each time. According to the method, target function change curves corresponding to different driving schemes are given, then the schemes are selected according to actual conditions, and for a final train, after the access time of the final train is determined, the driving schemes of the final train can be selected from optional schemes in the appointed connection direction in an alternative library. A practical problem is converted into a combination optimization problem under the condition that the number of schemes is limited, namely, an optimal driving scheme combination is selected for an accessed train, so that the requirement of convenient travel of cross-line travelers is met to the maximum extent, the railway operation expenditure is reduced to the maximum extent, and a compromise balance point is found in the two problems, namely, a driving scheme to be solved.

    本发明涉及智能交通技术领域,且公开了一种铁路跨线客流的枢纽内列车开行方法,构建轨道交通服务网络模型、构建跨线客流衔接的列车停站方案数学模型、建立并列关系的双目标规划,形成双目标非线性优化模型,每次仅考虑单个目标,给出不同开行方案所对应的目标函数变化曲线,再根据实际情况,从中挑选方案、针对终到列车,在其接入时刻确定后,其开行方案可以从备选库中指定衔接方向可选方案中进行选择。将实际问题转化为方案数有限情况下的组合优化问题,即为接入列车选择最优的开行方案组合,以最大化程度满足跨线旅客便捷出行的要求以及最大限度降低铁路运营支出,在二者中找到一个折中的平衡点,即为待求解的开行方案。
