Abstract
The capacity of the railway network line section and the arrival/departure capacity of marshaling stations are critical factors influencing the freight wagon flow routing decisions.By considering the lack of quantitative parametric support for the capacity of railway network points and lines during the daily adjustment of freight wagon flow routing,a calculation method of railway network point and line passing capacity for freight wagon flow routing was established.Firstly,the current situation of railway network development and overall capacity utilization were summarized.Secondly,based on the transportation organization principle and the influencing factors of railway network point and line capacity,as well as key data in the locomotive operation statistical report,two calculation methods were proposed for calculating the non-parallel freight wagon capacity and peak capacity of railway network sections.Based on the connection between the marshaling station and the railway network,a"point-to-line"method was adopted to transform the marshaling capacity into the arrival/departure capacity of the line in different directions.Finally,based on the statistical data of locomotives and freight wagons,an estimation method for the line section passing capacity and the arrival/departure capacity of different marshaling stations in different directions was proposed,which provided accurate data support for the high-quality adjustment of the railway freight wagon flow routing in China,laying a solid foundation for further research on the intelligent adjustment of wagon flow routing under the capacity constraint.关键词
