Parking　policies　have　significant　impacts　to　travel　mode　choice　and　traffic　system　operation.　Due　to　heterogeneous　travel　purpose,　people　perceive　the　same　parking　policy　mix　with　different　extent.　In　order　to　understand　the　existing　reason　about　different　perception　for　the　same　policy,　a　multi-ple-factor　behavior　model　has　been　developed,　by　considering　the　factors　of　parking　price,　public　transit　travel　time,　traffic　conditions　and　parking　supply　etc.　Three　major　findings　obtained　from　this　study　are　as　following:　the　first　finding　is　that　travel　mode　choice　has　been　significantly　affected　by　dynamic　traffic.　Second,　parking　price　and　bus　travel　time　have　important　effects　on　the　mode　choice　of　commuting　drivers.　Third,　the　non-commuting　drivers　are　more　sensitive　to　parking　price　than　commuting　drivers　only　when　making　mode　choice.　These　findings　provided　a　theoretical　reference　for　zoning　and　interval　management　of　the　parking　policy　mix.　©　2017　Taylor　&　Francis　Group,　London.
