复杂铁路网条件下城市可达性研究

Research on Urban Accessibility Under Complex Railway Road Network Conditions

基于城市间复杂铁路线网及交通枢纽研究城市可达性对交通规划具有重要理论支撑意义,本文分别提取中心城市到其他中心城市的时间、列车对数、最少站点数等数据,分析三个因素对可达性的影响,进一步定义可达性的优劣,采用离散度分析法对中心城市可达性水平进行综合评价研究,得出各地区城市的可达性优劣。

Based on the complex inter city railway network and transportation hub,the study of urban accessibility has important theoretical supporting significance for transportation planning.This paper extracts the time,train pairs and minimum number of stations from the central city to other central cities,analyzes the impact of three factors on accessibility,further defines the advantages and disadvantages of accessibility,and uses the dispersion analysis method to comprehensively evaluate the accessibility level of central cities and regions,The accessibility advantages and disadvantages of cities in various regions are obtained.
