The invention discloses a railway junction station train operation route selection method. The method comprises steps that a topological structure formed by station lines and turnouts of a junction station is abstracted into a directed graph; a steering punishment value of a turnout node is set to remove a line of which a steering angle of the turnout node is smaller than a set angle, and specified times are iteratively optimized by taking a junction station access distance and the turnout number as optimization targets and combining the directed graph so as to obtain an optimal train operation access. The method is advantaged in that the unreasonable steering condition of the turnout can be avoided, safety of the train entering process can be improved, train receiving and dispatching efficiency of a station can be improved, the punctuality rate of the train can be increased, so the change rate of a train running chart, running safety of the junction station and comprehensive utilization efficiency of transportation equipment are improved.

    本发明公开了一种铁路枢纽车站列车运行进路选择方法,包括:将枢纽车站的站线与道岔构成的拓扑结构抽象为有向图;设置道岔节点的转向惩罚值,来去除道岔节点转向角度小于设定角度的线路,并将枢纽车站进路距离和道岔数作为优化目标,结合有向图来迭代优化指定次数,从而获得最优列车运行进路。该方法可以避免道岔不合理转向情况出现,还可以提高列车进站过程的安全性,并且,还能够提高车站接发列车效率,有利于列车正点率的提高,从而提高列车运行图的兑现率、枢纽站行车安全和运输装备的综合运用效率。
