摘　　要：为计算城市内部特定区域对周边其他区域的公交可达性,更加直观地得到不同区域公交可达性差异程度,提出区域公交可达性概念.借助GIS空间分析功能,提出基于公交站点权重和公交线路辐射范围权重的区域公交可达性计算方法.以北京市朝阳区为例,计算朝阳区30个交通小区的区域公交可达性值.结果表明,区域公交可达性值,可以更加直观地展现城市内部不同区域对周边其他区域的公交可达性水平,这为选址分析、公交优化等提供了定量化的公交可达性信息.To calculate the public transit accessibility between a specific area and its surrounding areas, and to show the differences of the public transit accessibility more intuitive, a new concept is raised, this is area public transit accessibility （APTA）. Using the GIS spatial analysis, a method is introduced to calculate the APTA based on bus station and the boundary of the bus routes. Finally, a case study of Beijing Chaoyang district is conducted. The results show that the APTA can give us a clearly description, about the different levels of the public transit accessibility between a specific area and its surrounding areas. This provides quantitative information of public transit accessibility for location analysis and transit network optimizing.
