居住自选择视角下城市建成环境对通勤模式选择的影响OA北大核心CSTPCD

Research on travel mode choice is essential for efficient,sustainable,and safe urban traffic planning.This study selected the main urban area of Lanzhou City,Gansu Province,China as the study area,and based on the distributed cognitive theory,questionnaire data,road network data,and Point of Interest(POI)data.The struc-tural equation model was used to explore the impact of nonrandom heterogeneity of the built environment on se-lecting the commuting mode under the influence of the residential self-selection effect.The study found that:(1)Residents chose residential quarters with different built-environment characteristics according to their socioeco-nomic attributes and attitude preferences.Subsequently,they formed a specific commuting pattern,indicating preference heterogeneity in residential self-selection and the existence of the residential self-selection effect.(2)The built environment continued to have a considerable impact on the choice of commuting mode even after avoiding the self-selection effect of residence.Specifically,population density,road network density,and the num-ber of parking spaces directly affected the choice of commuting mode.Road network density,bus station accessi-bility,subway station accessibility,and the number of parking spaces indirectly influenced the choice of commut-ing mode through mediating variables,such as commuting distance and car ownership.(3)High-population densi-ty,dense road network,and high-accessibility of the built environment increased the active and public transporta-tion commuting modes.This was achieved by improving the connectivity of road networks,connection between walking and public transit,and pedestrian-friendly environment and by guiding residents to a shift in the travel structure,led by active commuting patterns.
