V2I (Vehicle to Infrastructure), allowing vehicles to communicate with the Infrastructure, is happening now. There are thousands of Road Side Units (RSUs) equipped with V2X chipsets spread across the US, Europe and Asia. Over 20 US states and 16 EU member states have active infrastructure deployment projects. Billions of dollars are planned to be invested in smart infrastructure capable of communicating with vehicles via V2X.
V2I is beneficial for manned and autonomous vehicles. In manned vehicles, the driver can get alerts as to road conditions, weather alerts, roadside construction, upcoming traffic lights state, and more.
Projects equipping RSUs with V2X and cameras allows drivers to get safety messages about dangers at intersections ahead of time. For autonomous vehicles, V2I has both safety and mobility benefits, enabling the infrastructure to point out hazards lying ahead as well as optimizing the flow of traffic.
