Mainline　coordinated　control　is　usually　based　on　fixed　speed　and　statistical　traffic　flow　by　period.　However,　in　actual　operation,　the　vehicles　parked　in　front　of　the　intersection　and　the　arriving　vehicles　often　fluctuate,　and　the　through-traffic　green　time　is　wasted　due　to　phase　transition,　which　leads　to　mismatches　between　the　signal　plans　and　actual　traffic　flow　requirements,　affecting　the　traffic　efficiency　of　the　intersection.　To　address　the　above　issues,　using　vehicle-road　collaborative　control　(VRCC),　by　calculating　the　phase　difference　lead　time　and　phase　difference　of　adjacent　intersections,　the　green　extension　time　for　the　green　wave　through-traffic　phase,　and　the　guiding　vehicle　speed,　the　goal　of　reducing　the　detention　volume　of　through　traffic,　reducing　the　waste　of　through-traffic　green　time　caused　by　phase　transitions　and　improving　the　throughput　of　through　traffic　can　be　achieved.　The　speed　of　the　green　wave　traffic　flow　is　increased　by　guiding　vehicles　to　form　saturated　platoons　during　green　periods.　Finally,　PTV　VISSIM　4.3　was　used　for　simulation　verification,　and　the　results　showed　that　compared　to　not　implementing　the　control　strategy,　the　average　delay　on　the　arterial　road　was　reduced　by　85.1%,　the　average　number　of　stops　was　reduced　by　84.3%,　the　average　travel　time　was　reduced　by　34%,　and　the　average　queue　length　was　reduced　by　62.6%.　This　significantly　improved　the　efficiency　of　traffic　on　the　arterial　road　and　effectively　reduced　congestion.
