In　order　to　improve　bus　service　level　after　installing　exclusive　bus　lanes,　this　paper　evaluates　the　satisfaction　of　bus　service　using　based　on　the　collected　data　in　Xining　City.　First,　considering　passengers’　needs,　a　satisfaction　evaluation　system　is　constructed　from　four　aspects　of　comfort,　convenience,　reliability,　and　security,　and　an　evaluation　model　of　entropy　weight　method　is　established.　Second,　combined　with　the　field　survey　data,　the　weight　of　each　index　was　determined,　and　the　satisfaction　evaluation　result　of　each　index　was　calculated.　The　overall　satisfaction　of　bus　lanes　was　3.78,　which　was　between　“general　satisfaction”　and　“satisfaction.”　Finally,　impacts　of　personal　attributes,　travel　attributes,　and　other　variables　on　satisfaction　were　analyzed.　The　results　show　that　comfort　and　reliability　are　the　focus　of　travelers,　intersection　delays　and　epidemic　causes　have　a　great　impact　on　public　satisfaction,　and　the　level　of　public　transport　service　needs　to　be　further　improved.　©　ASCE.
