With　the　development　of　society,　autonomous　driving　technology　has　developed　rapidly.　It　provides　a　new　way　of　travel　for　travelers.　The　shared　Autonomous　Vehicles　are　the　product　of　the　combination　of　autonomous　vehicles　and　sharing　economy.　It　can　provide　travelers　with　travel　services　on　demand.　This　study　constructs　a　model　of　travelers＇　willingness　to　accept　a　carpooling　ride　under　the　condition　of　autonomous　driving　and　shared　car　travel　and　discusses　travelers＇　carpooling　preference　in　the　travel　process.　The　results　show　that　the　travelers＇　willingness　to　accept　a　carpooling　ride　under　the　automatic　driving　mode　is　closely　related　to　the　characteristics　of　daily　commuting　travel,　carpooling　characteristics　and　personal　attributes.　This　paper　provides　a　theory　basis　for　the　study　of　carpooling　choice　intention　of　private　car　commuters　and　non-private　car　commuters,　and　provides　a　corresponding　basis　for　the　formulation　of　ride-sharing　policy,　traffic　resources　and　the　alleviation　of　traffic　congestion.　©　ASCE.
