摘　　要：以候车时间、运行时间、换乘时间组成单程通达时间,进而构建包含7个基于通达时间概念的评价指标,提出一套对轨道交通站点、线路和网络整体可达性进行评价的方法。并以北京2013年6月的轨道交通网络为例,采用官方公布及现场实测数据,通过ArcGIS软件,应用该方法进行了案例分析,在网络、线路和空间分布3个方面分别得到了评价结果。从结果来看,由于空间绝对距离和换乘站点数量的原因,中心城区线路可达性优于外围线路;站点密度较高和换乘困难可导致线路可达性较弱。Trip access time is formed by waiting time, running time and transfer time, and 7 evaluate indicators based on access time are built and the whole network of urban rail transit is raised. Take the example of Beijing rail network in June, 2013, and apply the method to them for case study. The result is reached in 3 aspects as network, lines and spatial distribution. For the result, because of the absolute distances and the number of transfer stations, accessibility of central city lines is better than peripheral lines; high density of stations and hard transfer lead to weak accessibility. For the method itself, evaluate result, and comparison with actual data, this method can be considered reliable, and with characteristic of intuitive and accuracy, which has certain reference value for construction of urban rail network in future for Beijing and other cities where the urban rail transit is in a similar stage of development.
