摘要
研究综合交通接驳下的轨道交通站点可达性对于优化站点周边的接驳环境、完善城市综合交通运输系统衔接、保证综合交通运输系统一体化发展具有重要意义。为此,融合手机信令数据与高德地图路径规划应用程度接口(Application Programming Interface,API)数据,以精准识别轨道交通乘客的出行行为为基础,从乘客实际出行需求的角度出发,采用置信椭圆方法识别了轨道交通站点的服务范围。随后,以花费的时间成本为指标,构建了交通可达性模型,对轨道交通站点及线路的综合交通可达性进行了分析,并以大连市轨道交通1号线和2号线为例进行了验证。研究结果表明,轨道交通站点的服务范围近似于一个短半轴平行于轨道交通线路方向、长半轴垂直于轨道交通线路方向的椭圆;轨道交通的接驳方式以步行为主、公交为辅;常规公交可达性在不同轨道交通站点间存在巨大的差异,是造成轨道交通站点可达性差异的主要原因;线路首尾端站点的可达性相对较差。在此基础上,提出了改善措施建议,旨在为轨道交通的发展和综合交通运输网络的衔接和优化提供参考。
Studying the accessibility of urban rail transit stations under comprehensive transportation connection is of great significance for optimizing the surrounding transportation connections,improving the connection of urban comprehensive transportation systems,and ensuring the integrated development of comprehensive transportation systems.In this study,mobile signaling data and path planning data from the Gaode map API were integrated to accurately identify the travel behavior of rail transit passengers.From the perspective of actual travel demand,the confidence ellipse method was used to identify the service range of rail transit stations.Subsequently,using time cost as the indicator,a transportation accessibility model was constructed to analyze the comprehensive transportation accessibility of rail transit stations and lines,and the model was verified through the case study on Dalian Metro Line 1 and Line 2.The research results show that the service range of rail transit stations is approximately an ellipse with a short axis parallel to the direction of the rail transit line and a long axis perpendicular to it.Walking is the main mode for rail transit connections,supplemented by buses.The significant differences in accessibility by regular buses among different rail transit stations are the main reason for the differences in comprehensive transportation accessibility of rail transit stations.The accessibility of terminal stations is relatively poor.And relevant improvement measures were proposed,providing reference for the development of rail transit and optimization of comprehensive transportation network.
