摘　　要：本文从交通可达性研究入手,分析了目前轨道交通站点可达性存在的问题,提出了考虑城市空间阻隔情况下站点实际覆盖度的问题。以问题为导向,借助百度地图API技术,建立基于百度地图API求解站点可达性的模型,并开发可自动识别站点可达性的应用程序。通过对首都功能核心区的全部68座车站在该程序上的应用,发现了由于道路可达性影响下轨道交通站点的实际可达性范围与理论服务范围的偏差情况。随着城市化的进程,城市公共服务设施要进行深度的精细化设计,就要求前期分析阶段能够掌握更为真实的交通服务数据。本文对交通可达性的分析,是精细化设计的重要基础依据。Starting from the study of traffic accessibility,this paper analyzes the existing problems in the accessibility of rail transit stations,and puts forward the problem of actual station coverage according to the conditions of the urban space barrier.Oriented by the problems,with the help of Baidu map API technology,this paper establishes a site accessibility model based on Baidu map API,and develops an application program that can automatically identify the site accessibility.Through the application of the program to all 68 stations in the capital functional core area,the deviation between the actual accessibility range and the theoretical service range of rail transit stations under the influence of road accessibility is found.With the process of urbanization,in order to carry out in-depth fine design of urban public service facilities,it is necessary to grasp more real traffic service data in the early analysis stage.The analysis of traffic accessibility in this paper is an important basis for fine design.
