Built environment characteristics differentiallyinfluence NMTandrail transit shares，whilecarusage primarilycorrelates with socioeconomic atributes.Third，through hierarchical clusteringanalysisbasedon travelmode structureand key influencing factors，three major categories with eightsubtypes ofstations are identified.To enhance the traffcregulation effect of rail transit， targeted TOD planning strategies should be implemented.
