With　the　rapid　increase　of　vehicle　population　and　land　shortage　of　urban　center,　parking　problem　becomes　an　integral　part　of　transportation　planning　and　management.　Due　to　out　of　work,　many　residential　areas　of　private　parking　spaces　are　in　idle　state　during　day　time.　These　vacant　parking　spaces　can　be　effectively　used　by　parking　sharing　to　meet　the　parking　demand　of　nearby　work,　shopping　or　other　activities　of　drivers.　However,　the　implementation　of　parking　sharing　must　solve　a　problem,　that　is,　the　conflict　between　the　provider　and　the　user.　This　paper　focuses　on　how　to　implement　the　parking　sharing,　so　that　in　the　case　of　conflict　avoidance　parking　managers　gain　the　most.　Copyright　©　2017　by　Science　Press.
