A　method　to　select　a　suitable　operation　mode　of　PPP　projects　of　public　parking　lots　was　provided.　The　characteristics　and　application　scope　of　PPP　modes　were　analyzed.　Based　on　the　characteristics　of　public　parking　lots,　the　influence　factors　and　mechanism　of　PPP　operation　mode　selection　were　obtained.　A　decision-making　index　of　PPP　operation　mode　selection　was　established,　and　operation　mode　selection　model　based　on　AHP　was　prompted.　An　example　was　given　using　the　data　from　an　old　residential　area　in　Beijing.　The　results　suggested　that　parking　characteristics,　internal　rate　of　return,　and　charging　probability　are　the　most　important　influencing　factors,　which　scored　0.6267,　0.5434,　and　0.2391,　respectively.　The　score　of　BOO　mode　is　0.2534,　which　is　the　highest　one　among　various　types　of　PPP　modes.　It　can　be　concluded　that　the　most　suitable　PPP　operation　mode　adopted　in　public　parking　lots　in　residential　areas　should　be　BOO　mode.　The　study　can　provide　technical　support　for　operation　mode　selection　of　PPP　projects　of　public　parking　lots.　©　2018　American　Society　of　Civil　Engineers.
