高速铁路网运输能力计算与运用优化研究OA

The influencing factors of transportation capacity of high speed railway networks are numerous and have strong coupling.Currently,there is no consensus on the definition,system,and evaluation indicators for the transportation capacity of the railway network.Researching the transportation capacity of high speed railway networks has important theoretical and practical significance for railway network structure adjustment and capacity utilization optimization.On the basis of analyzing the influencing factors of transportation capacity of high speed railway networks from three aspects of infrastructure,mobile equipment,and transportation organization plan,the generation mechanism and system composition of transportation capacity of high speed railway networks based on the coupling effect of the three aspects were proposed,and the corresponding evaluation indicators were given respectively.Moreover,a calculation conceptual model for the effective transportation capacity of high speed railway networks was analyzed and proposed.Furthermore,targeted optimization schemes for transportation capacity of high speed railway networks were proposed from three aspects:infrastructure utilization optimization,mobile equipment capacity utilization optimization,and transportation organization mode.The related research provides theoretical support for the definition,calculation,and utilization optimization of transportation capacity of high speed railway networks.
