Roadside unit (RSU)

Current consensus

A roadside unit is a V2X device used to transmit to, and receive from, V2X-equipped moving vehicles (OBUs). The RSU transmits from a fixed position on the roadside (which may be either a permanent installation or “temporary” equipment brought on-site for a period of time associated with an incident, road construction, or other event). Some RSUs have the ability to transmit signals with greater power than OBUs and some may have connectivity to other nodes or the Internet.
