The pedestrian space environment within 800 meters of seven metro stations in the central city of Dalian was used as the research object.Through a questionnaire survey of 719 pedestrians,the internal correlation between the micro built environment and the walkability of the metro catchment area was explored with the help of structural equation modeling.The study found that there were six latent variables affecting station walkability,with"convenience"dominating the study.In conjunction with the field research,sidewalk crossings,overpass crossings,underpass crossings,and signage in the built environment were identified as highly efficient imbalance indicators,and targeted optimization initiatives were proposed.
