研究目的:合理确定线路在铁路网中的作用对合理进行路网规划、合理配置线路技术标准具有非常重要的作用,但目前尚无定量的研究方法。本文建立了线路可达性等级模型,用线路可达性等级定量反映线路在路网中的作用和地位,为路网的规划和设计中对线路作用的定位提供了一种定量的手段和依据。研究结论:通过对东北铁路网线路可达性等级的计算,验证了该方法的实用性,并得出线路可达性等级与铁路等级之间存在很大的相关性。此方法可以应用于路网规划、路网分析和评价等领域中。
Research purposes: Reasonably determine the role of line in the railway network is very important for the rational planning of road network and reasonable allocation of line technical standards, but there is no quantitative research method. This paper establishes a line accessibility model to quantitatively reflect the role and position of the line in the road network with the line accessibility level, which provides a quantitative means and basis for the positioning of the line in the road network planning and design . Research conclusions: Through the calculation of the reachability level of the railway network in Northeast China, the practicability of this method is verified, and it is concluded that there is a great correlation between the reachability level and the railway grade. This method can be applied in the field of road network planning, road network analysis and evaluation.
