Application Summary AI generated

This standard specifies the medium access control (MAC) and physical layer (PHY) protocols for dedicated short-range communications (DSRC) in cooperative intelligent transportation systems (C-ITS). It is applied in vehicle-to-roadside (V2I) communication scenarios, such as electronic toll collection (ETC), traffic signal priority for emergency vehicles, and real-time traffic information exchange. The standard ensures reliable, low-latency wireless data transmission between vehicles and roadside infrastructure operating in the 5.9 GHz frequency band.
