As　an　effective　way　to　relieve　urban　traffic　congestion,　public　transport　has　been　attracting　much　attention.　However,　the　quality　of　ground　bus　service　in　most　cities　in　China　is　low,　the　passengers　are　not　satisfied,　which　leads　to　the　decrease　of　the　share　rate　of　bus　passenger　flow.　Based　on　the　questionnaire　survey　data,　this　paper　constructed　a　ground　bus　service　quality　evaluation　system　from　the　perspective　of　passenger　perception,　determined　four　analysis　dimensions　of　comfort,　convenience,　security,　and　reliability,　and　14　second-level　evaluation　indexes,　and　determined　the　weight　of　each　index　by　expert　survey　method　and　analytic　hierarchy　process.　Then,　the　SERVQUAL　service　quality　evaluation　model　was　built　to　skillfully　quantify　service　quality　indicators.　Finally,　the　paper　took　the　public　transport　in　Jiaozuo　city　of　Henan　province　as　an　example　to　verify　that　the　service　evaluation　model　can　effectively　reflect　the　service　quality　of　ground　public　transport.　©　2020　ASCE.
