Comprehensive Overview of V2X (Vehicle-to-Everything)

Definition and Core Value

V2X refers to an intelligent system that enables vehicles to connect with everything through wireless communication technology. Its primary objectives are:

Safety: Reduce over 90% of traffic accidents (NHTSA data)

Efficiency: Optimize traffic flow and reduce congestion (e.g., green light coordination)

Intelligence: Provide environmental perception support for autonomous driving
