The　traffic　congestion　in　ramp　areas　is　becoming　increasingly　prominent.　In　the　upstream　segments　of　ramp　areas,　effective　management　and　control　of　lane-changing　behaviors　can　improve　the　road　capacity　and　make　full　use　of　the　existing　road　resource.　With　the　continuous　development　and　application　of　connected　vehicle　technologies,　lane-changing　behaviors　can　be　performed　by　vehicle　groups.　Under　a　connected　vehicle　environment,　the　lane-changing　behaviors　by　vehicle　groups　are　controlled　in　the　upstream　segment　in　a　ramp　area,　and　the　lane-changing　behaviors　can　be　completed　prior　to　entering　the　ramp　area.　Finally,　lane-changing　strategies　are　optimized　and　identified.　VISSIM　simulates　these　proposed　strategies.　This　paper　considers　the　delay　as　the　output　index　for　analyzing　and　comparing　various　strategies.　The　results　demonstrate　that　the　delays　of　different　lane-changing　strategies　are　also　different.　If　the　delays　of　ramp　areas　are　to　be　substantially　reduced,　it　is　necessary　to　continuously　optimize　the　lane-changing　strategies　by　vehicle　groups　in　the　upstream　segments.　This　optimization　of　lane-changing　strategies　will　effectively　regulate　drivers＇　lane-changing　behaviors,　improve　road　safety,　and　increase　traffic　capacity.
