Which term describes the relationship between vehicles and infrastructure?

The term that describes the relationship between vehicles and infrastructure is V2I, which stands for Vehicle-to-Infrastructure communication. This technology involves the exchange of information between vehicles and various elements of transportation infrastructure, such as traffic lights, road signs, and sensors. The primary goal of V2I communication is to enhance safety, improve traffic flow, and facilitate more efficient transportation systems. This interaction enables vehicles to receive real-time data about road conditions, traffic signals, and potential hazards, allowing for better decision-making by drivers and automated systems alike.

In contrast, other terms like V2V (Vehicle-to-Vehicle) focus on communication between vehicles themselves to prevent collisions and enhance cooperative driving technologies. V2P (Vehicle-to-Pedestrian) involves interactions between vehicles and pedestrians, often aimed at improving safety for those who are on foot. V2R (Vehicle-to-Roadside) refers to similar concepts but is less commonly used. Each of these terms describes different aspects of connected vehicle technology, but V2I is specifically about the relationship with infrastructure.
