Abstract: V2X, as key technologies of intelligent and connected vehicle, can implement to support vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), vehicle-to-network(V2N) scenarios. Furthermore,V2Xcan be deployed to enhance the ability of vehicle information collection. In this paper, two main V2X techniques, also known by DSRC and LTE- V, are introduced from network architecture, standard progress and technique designs. Finally, some simulation results are given basedon several classical scenarios.
