摘　　要：城市轨道交通一旦发生突发情况,列车将无法按既有的运行图行驶,而等间隔行车调整能简单有效地恢复运营秩序。针对列车运行紊乱的问题,为优化恢复运营秩序的效率,文章设计了一种高效等间隔调整方法,其通过计算各列车间的追踪间隔,得到列车群在时间维度的相对位置;并以列车群最短时间达到等间隔行驶效果为优化目标,寻找每辆列车的最优待调整时长;最后通过调整停站时长和运行等级,将每辆列车的待调整时长调整至零,从而实现列车群等间隔行驶。文中设计了5种场景进行仿真验证,并将提出的方法与前后车平均间隔法及前车到站时刻判断法进行仿真比较,结果显示本方法的调整效果优于另外两种方法时,验证了本方法工程化应用的有效性及调整过程的高效性。In the event of an emergency in urban rail transit,train will not be able to run according to the existing operating chart,and the adjustment of the train at equal intervals can simply and effectively restore the operational order.Aiming at the problem of train running disorder,in order to optimize the efficiency of restoring operation order,a constant train regulation method is designed in this paper.By calculating the tracking interval between each train,a relative position in the time dimension of the train group is obtained;taking the shortest time of the train group to constant interval status as the optimization goal,the optimal time to be adjusted for each train is obtained.Finally,by adjusting the stopping time and the operation level,the time to be adjusted of each train is adjusted to zero,so that the train group can travel at equal intervals.In this paper,five scenarios are designed for simulation verification,and the method is compared with the average interval method and the arrival time judgment method.The results show that the adjustment effect of this method is better than the other two ones’,which verifies the engineering application effectiveness of this method and the efficiency of the adjustment process.
