摘要
铁路车流推算要计算货车在区段内的运行时间和在车站的停留时间,然后才能推算货车到达各站的时间。当货车跟随列车到达编组站时,通常要进行有调或无调中转作业,中转方式的不同对于推算货车停站时间有很大影响。通过研究货物列车编组计划的内容,梳理出直达列车数据表和直通列车数据表。车流推算时,先分析经由编组站串,然后依据直达列车数据表判定货车是否属于直达。对于非直达的货车,依据直通列车数据表,设计了判断货车经由编组站中转方式的递归算法。使用此方法可以快速判定货车在编组站中转方式,从而使计算停站时间更加准确。
Calculating running times in railway sections and waiting times in railway stations are the base to forecast the time when the vehicle will arrive at each station in railway vehicle flow forecast.Generally,vehicles will have two transfer mode in marshalling station,such as shunting operations and no-shunting operation.The vehicle's transfer mode will heavily affect its waiting time in marshalling stations.The contents of train formation plan are analyzed,and through trains data table and direct trains data table are conducted.The sequence of visiting marshalling station is analyzed first in vehicle flow forecast,then the through attribute of each vehicle can be determined by using through trains data table.For a vehicle having no through attribute,the recursion algorithm is designed to determine its transfer mode by using direct trains data table.This algorithm can quickly determine the transfer mode,and is helpful to forecast more accurate waiting time at marshalling stations.
