基于距离微化因子的列车运行时间的预测模型

针对当前城市轨道交通无线集群调度仿真系统列车运行时间估算不准确,列车显示不连续,有时提前到站,有时滞后到站和列车跳着前进等问题,在线性预测模型的基础上,引入了距离微化因子,提出了一种基于距离微化因子的列车运行时间的模型。结合列车运行实际情况,通过在模型中引入距离微化因子,细化运行时间占比,实现列车运行时间的预测。仿真结果验证了模型的适用性与准确性。

In view of the inaccurate estimation of train running time in the current urban rail transit Wireless Cluster dispatching simulation system, an improved model of train running time for urban rail transit is proposed in this paper. The distance miniaturization factor is introduced into the model to ref ine the known data and improve the prediction accuracy. The simulation results verify the applicability and accuracy of the model.
