This　study　on　attractive　region　of　rail　transit　station　is　based　on　the　travel　time　from　original　position　to　rail　transit　station.　Diversification　of　attractive　region　caused　by　traffic　service　level　is　not　considered　adequately　in　current　practices.　In　order　to　consider　the　effect　of　traffic　service　level,　the　traveler　behavior　is　studied　and　disaggregate　model　of　rail　station　selection　based　on　the　theory　of　the　maximum　travel　utility　is　established.　The　utility　of　rail　traffic　station　selection　is　determined　by　the　colligation　of　individual　characters,　travel　characters　and　traffic　service　level.　Based　on　the　result　of　utility　and　Reilly＇s　Formula,　attraction　of　the　rail　transit　station　and　the　attraction　intensity　of　the　given　position　around　the　station　are　given.　Furthermore,　attractive　region　of　both　isolated　stations　and　stations　in　the　rail　network　are　studied.　Copyright　ASCE　2007.
