As　the　key　node　of　public　transportation　system,　subway　station　has　many　functions　such　as　attracting　and　distributing　passengers　and　guiding　the　transfer　from　various　traffic　modes　to　subway.　However,　the　poor　facility　scale　and　layout　around　subway　stations　in　practice　usually　cause　the　inconvenience　of　transfer　and　low　transfer　efficiency,　which　causes　the　declination　of　travel　efficiency　and　even　loose　of　subway　passengers.　Taking　subway　stations　as　the　study　objects,　this　paper　has　emphasis　on　the　connection　characters　between　various　traffic　modes　and　subway　stations.　Considering　the　attraction　region,　the　total　transfer　time,　transfer　distance,　and　connection　cost　were　selected　to　form　the　efficiency　index　of　connection　layout　of　subway　stations.　Data　envelopment　analysis　(DEA)　model　is　applied　in　the　quantization　of　traffic　resource　consumption　and　output.　At　last,　connection　facility　layout　model　of　subway　stations　was　established　with　the　aim　of　improving　the　transfer　efficiency.　Meaningful　results　were　obtained　from　the　connection　layout　model　of　subway　stations,　which　guide　the　planning　and　designing　of　the　transfer　facilities　around　subway　stations.
