In　this　paper,　by　combining　controller　area　network　(CAN)　bus　data　and　bus　IC　card　data,　the　influence　factors　of　emission　of　transit　vehicles　are　analyzed　from　two　aspects:　at　the　segment-level　and　the　bus　stop-level.　Statistically,　the　bus　lane＇s　average　speed　is　fast,　about　30%　higher　than　non-bus-lane　road.　Then,　MOVES　was　used　for　emissions.　Finally,　a　regression　of　segment　level　emissions　and　bus　stop　level　energy　consumption　against　a　number　of　variables　was　done.　The　results　show　that　the　emissions　of　the　transit　bus　can　be　reduced　if　it　is　on　the　bus　lane.　On　the　bus　stop　level,　the　idling　time　and　the　braking　time　are　affected.　More　interesting,　when　there　are　a　lot　of　people,　the　emissions　and　energy　consumption　start　to　decrease.　Our　findings　are　most　relevant　for　transit　planners　who　are　seeking　strategies　to　reduce　emissions　and　energy　consumption.　©　2018　American　Society　of　Civil　Engineers　(ASCE).　All　rights　reserved.
