Analysis Of Influencing Factors On Accessibility Of Urban Rail Transit Stations

With the continuous improvement of my country’s urbanization rate and the increasingly prominent urban traffic problems,domestic first-and second-tier cities have begun to enter the fast lane of urban rail transit construction one after another.As the main gateway of the urban rail transit system,the urban rail transit station undertakes the important functions of the surrounding passenger flow distribution and line passenger flow transfer.In actual operation,it is affected by various factors such as site space layout,land development and slow-moving environment.,there is a big difference between the actual accessibility and theoretical accessibility of different types of stations,which also leads to the low utilization efficiency of some stations.Therefore,how to scientifically analyze the influencing factors of the accessibility of urban rail transit stations is important.meaning.Based on the difference in travel modes of travelers on the urban rail transit network and the urban street network,this paper firstly divides the accessibility of stations into station-to-station accessibility and station-domain accessibility.For example,the actual accessibility of the site is analyzed and measured in combination with the traveler’s actual travel data.Then,based on the analysis of site accessibility distribution characteristics,the influencing factors of site accessibility are explored by using Person correlation coefficient,global Moran index,local cluster analysis,travel characteristics and travel satisfaction analysis.In the analysis of the influencing factors of inter-station accessibility,based on the AFC data of subway travel,combined with the travel cost of the Auto Navi open platform,the correlation analysis and spatial autocorrelation analysis of the influencing factors of inter-station accessibility were carried out,and the station’s Inter-station accessibility strength is not only affected by the location of the station and the surrounding land,but also has a significant correlation with the path time,path distance,transfer times and number of stops between stations.In the analysis of the influencing factors of the accessibility of the station domain,based on the mobile phone signaling data around the site,combined with the field survey and travel satisfaction survey data,the correlation analysis and the comparative analysis of travel characteristics were carried out,and the station domain accessibility of the site was obtained.There is a significant correlation with illegal occupation,street vitality,travel interference and nighttime lighting.In addition,under the different land use properties,road network density and pedestrian space quality in the station area,the acceptable distance and time for walking at the station are relatively large.Differences,the proportion of residential land,the density of road network and the goodness of pedestrian space have a positive correlation with the pedestrian accessibility of the station area,while travel interference,illegal occupation and route detours have a negative impact on the pedestrian accessibility of the station area.affect the correlation.
