【Abstract】With the in-depth application of intelligent network technology in the field of transportation， vehicle-road cooperationsystemhas graduallybecome thecoresupport architectureof intellgent transportation.This paper focuses on the design and performance optimization of cross-layer communication protocols，and proposes a performance-oriented path，including reversible behavior inference model，unified scheduling function framework， event-driven path construction method and semantic abstraction compression mechanism.Then，a multi-scene highfidelitysimulation platform integratingNS-3andSUMO wasconstructedto verifytheeffectof theoptimizationprotocol around traffic patterns such as city intersection and high-speed lane change.The results show that the proposed scheme is highly adaptable to complex environment and can provide reference for the furtherdevelopment of crosslayer communication protocols.
