Vehicle-to-Infrastructure (V2I) is a technology that enables communication between vehicles and road infrastructure, such as traffic lights, road signs, and toll booths. This connection allows vehicles to receive real-time information about traffic conditions, road hazards, and other important data, enhancing safety and efficiency on the roads. By sharing information, V2I can help reduce traffic congestion and improve overall transportation systems. For example, when a vehicle approaches a traffic light, it can receive signals about whether the light will change, allowing for smoother driving and less waiting time. This technology is a key component of the broader Vehicle-to-Everything (V2X) ecosystem.
