Public　transit　priority　is　very　important　for　relieving　traffic　congestion.　The　connotation　of　dynamic　public　transit　priority　and　dynamic　stochastic　park　and　ride　is　presented.　Based　on　the　point　that　the　travel　cost　of　public　transit　is　not　higher　than　the　travel　cost　of　car,　how　to　determine　the　level　of　dynamic　public　transit　priority　is　discussed.　The　traffic　organization　method　of　dynamic　public　transit　priority　is　introduced.　For　dynamic　stochastic　park　and　ride,　layout　principle,　scale,　and　charging　standard　are　discussed.　Traveler　acceptability　is　high　through　the　analysis　of　questionnaire　survey.　Dynamic　public　transit　priority　with　dynamic　stochastic　park　and　ride　has　application　feasibility.
