摘要：鉴于国内大都市微观单元公交出行就业可达性研究少,采用微观单元空间数据和网络分析法,测算地铁影响下北京公交出行就业可达性,探讨轨道交通对大都市就业可达性的影响特征。结果显示,首先,北京公交出行等时圈呈现网络状扩展,可达时间由中心向外围梯度增长,高密度公交线路对地铁网络等时圈具有"放大效应"。其次,四环以内可达性整体水平高,且北部地区地铁站点周边形成高可达性区域,五环以外区域整体可达性依然较低。第三,新增可达性区域呈现围绕地铁站点的同心圆格局,并且集中于四环以内。新建地铁网络对旧地铁线路可达性有"放大效应",尤其是枢纽站点。最后,通过公共交通组合出行模式和公共交通公众查询系统可提高外围区域可达性。
With the support of massive spatial data and network analysis model,the study constructed spatial analysis model network to analyze the Beijing public transportation trip employment accessibility and its evolution under the influence of subway.This paper discussed the impact on employment accessibility from the subway.The results show that:firstly,Beijing transit network isochrones extends along the main subway network,the time gradient increases from the center to the periphery,and high density bus lines amplify the effects from the subway network.Secondly,the whole accessibility level is comparatively higher in the region of four circle road.In addition,there are lots of regions of higher accessibility around the northern subway stations.The whole accessibility level is lower out of the regions of five circle road.Thirdly,the new subway line amplifies the accessibility of the old subway network,especially for the hub stations.Obviously,the subway can improve the average travel efficiency.At last,urban public transport combination pattern and improvement of the public transport query system toward the region of lower accessibility can be applied in order to improve the subway transfer efficiency.
