How do Connected Vehicles Communicate?

Connected vehicles (CVs) rely their ability to maintain situational awareness through multiple communication systems collectively known as vehicle-to-everything (V2X). This V2X consists of vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P) and vehicle-to-network (V2N). These communication systems rely on wireless technologies such as dedicated short range communications (DSRC) developed specifically for CV usage. Signals are sent via DSRC by on-board units (OBU) and roadside units (RSU). CVs also use technologies such as GPS, Bluetooth, LiDAR, RADAR and cameras to “read” the roadway and its surroundings and send data to the vehicle to achieve an appropriate response to the given situation.
