Vehicle-to-infrastructure (v2i)

Definition

Vehicle-to-infrastructure (v2i) refers to the communication technology that enables vehicles to communicate with road infrastructure, such as traffic signals, road signs, and other elements that aid in transportation management. This interaction is crucial for enhancing traffic flow, improving safety, and optimizing urban mobility, especially in the context of autonomous vehicles and intelligent transportation systems that rely on real-time data to make informed decisions.

5 Must Know Facts For Your Next Test

1. V2i systems can significantly reduce traffic congestion by allowing vehicles to receive information about traffic conditions and adjust their routes accordingly.
2. This technology plays a vital role in improving road safety by enabling vehicles to receive alerts about hazards or changes in road conditions from infrastructure sources.
3. V2i supports the functioning of autonomous vehicles, which depend on accurate information from infrastructure to navigate complex environments safely.
4. The integration of v2i into urban planning can lead to more efficient public transportation systems by facilitating better coordination between buses, trams, and traffic signals.
5. Privacy and security concerns are significant challenges for v2i systems, as they involve the transmission of potentially sensitive location and movement data.
