摘要：

The　Full　Velocity　Difference　Model(FVD)　had　been　calibrated　and　verified　based　on　the　real　traffic　data　to　reflect　the　car-following　behavior　of　the　mixed　traffic　flow　at　the　intersection　approach　during　the　signal　green　time.　However,　the　simulation　results　showed　big　gaps　on　acceleration,　speed　and　vehicle　spacing　by　using　the　FVD　model.　This　study　considered　the　differences　of　vehicle　types　and　driver＇s　behavior　at　four　scenarios:　car　following　car,　car　following　bus,　bus　following　car,　and　bus　following　bus,　and　then　developed　a　new　car-following　model.　The　analysis　results　show　that　the　performance　of　the　proposed　model　has　been　significantly　improved,　and　the　Root　Mean　Square　Percentage　Errors　(RMSPE)　of　speed　and　vehicle　space　are　15.29%　and　22.32%,　respectively,　which　are　lower　than　the　FVD　model　results.　The　improved　model　performs　better　than　the　FVD　model　in　describing　the　car-following　behavior　at　approaches　of　signalized　intersections.　Copyright　©　2020　by　Science　Press.
