我国铁路车流径路方案一般以最短径路为原则,然而在实际运输中,综合考虑各种复杂因素的非最短径路运输方案却是客观存在的,且有其存在的合理性和必要性。为此,分析合理的非最短车流径路存在的原因,并对其进行理论解析,提出运营成本函数和车流径路选择,结合第六次铁路大提速说明合理的非最短车流径路理论在实际中的应用。 However, in the actual transportation, the non-shortest route transportation scheme considering all kinds of complex factors is an objective one, and its rationality and necessity exist. Therefore, this paper analyzes the reasons for the existence of reasonable non-shortest route, and analyzes the theory. The paper proposes the selection of operation cost function and route choice. Combined with the sixth speeding theory, it shows that reasonable non-shortest route theory is applied in practice. .
