In　response　to　the　micro-center　concept　proposed　by　the　Beijing　Municipal　Government.　This　article　explores　the　Transit-Oriented　Development　(TOD)　efficiency　evaluation　of　the　metro　station　buffer　area.　Adequate　multi-mode　public　travel　is　considered　as　the　goal　of　TOD　development.　Twelve　characteristics　are　selected　as　key　factors　of　TOD　efficiency.　To　improve　the　efficiency　description　capability　of　the　data　envelopment　analysis　model.　A　refined　and　efficient　TOD　efficiency　assessment　model　is　proposed　based　on　the　method　of　data　envelopment　analysis.　In　addition,　the　derivative　factors　of　passenger　flow　are　extracted,　and　the　correlation　between　them　and　TOD　efficiency　was　analyzed　from　the　characteristics　of　the　spatiotemporal　distribution　of　passenger　flow.　The　results　show　that　the　TOD　efficiency　of　the　metro　station　buffer　was　positively　correlated　with　the　85%　quartile　distance　of　shared　bicycle　connection　and　the　ratio　of　the　evening　peak　coefficient　of　inbound　passenger　flow　and　outbound　passenger　flow.The　85%　quartile　distance　of　shared　bicycle　connection　is　positively　correlated　with　connection　time　and　negatively　correlated　with　connection　volume.　Practice　has　proved　that　the　correlation　between　them　is　non-linear,　and　there　is　an　equilibrium　state.　The　proposed　model　efficiently　evaluated　the　TOD　efficiency　of　the　metro　station　buffer　area.　The　research　results　provide　references　for　urban　management　and　decision-makers　in　the　future.　©　2022　IEEE.
