摘要

为提高铁路货物运输的时效性,概述我国铁路货物运输供需矛盾变化,在现有技术站车流组织模式的基础上,对技术站车流来源依据车辆的特征进行分析并分类,提出在技术站采用以节约运输时间为目标的车流运动集结法,即将列车信息在其未到达技术站前就考虑在列车换挂重组的方案中,以达到压缩技术站车流集结等待时间的目的。在对该方法进行论证时,建立车流运动集结法节约运输时间的计算模型,并用实际数据进行检验,得出该方法确实可以节约车流集结时间,达到提高铁路运输时效性的目的。
        To improve the timeliness of railway freight transportation, this paper first summarizes the changes of the contradiction between supply and demand of railway freight transportation in China. On the basis of the existing organization mode of the traffic flow in technical stations, according to the characteristics of the vehicles, the paper analyzes and classifies the sources of the traffic flow in technical stations, and then proposes a method of traffic flow aggregation aiming at saving transportation time in technical stations. That is to say, according to the train information which is running to the technical station on the way, we should seek a better consideration in the scheme of train transfer and restructuring before arriving at the technical station, so as to achieve the purpose of reducing the waiting time of train flow gathering in the technical station. In the theoretical demonstration of this method, the calculation model of saving transportation time by the method of vehicle flow motion aggregation is established, and the actual data are used to verify the model. It is concluded that this method can indeed save the time of vehicle flow gathering and achieve the purpose of improving the timeliness of railway freight transportation.
