G2V, or "G2V" (Ground to Vehicle), refers to the communication and data exchange between ground systems and vehicles, particularly in the context of autonomous or connected vehicles. This technology enables vehicles to receive real-time information from ground-based sources, such as traffic signals, road conditions, and other vehicles, enhancing safety and efficiency. The G2V system is crucial for the development of smart transportation networks, where vehicles can interact with infrastructure and other entities. This interaction helps in optimizing routes, reducing congestion, and improving overall traffic management, contributing to a more efficient urban environment.
