Definition
V2I is a communication framework that allows vehicles to wirelessly exchange data with smart infrastructure, like traffic lights, signs, and cameras.
V2I systems improve safety and efficiency by analyzing the collected data and advising road users in real-time about incidents like congestion, road conditions, etc.
Applications of Vehicle-to-Infrastructure
- Dynamic traffic control.
- Live speed management.
- Notification about emergency vehicles.
- Notifications about traffic jams or accidents.
Why Do We Need V2I
With the introduction of autonomous self-driving cars, real-time information about road conditions, recommended speeds, traffic signals, and potential hazards is needed. The information collected by V2I systems can help autonomous cars make safe decisions on the road and identify areas where infrastructure improvements are needed.
What Could Some V2I Technologies Look Like
- Advanced road markings: A pavement marking visible to humans and machines in any weather condition would be a great addition. It would improve safety by ensuring lane discipline for autonomous vehicles and humans using the road.
- Smart signs: We need a signage system that creates signs visible to humans and machines. Smart signs would help machines and humans make quick decisions and more accurate navigations.
- Wireless communication: We also need wireless communication that relays real-time traffic and road information to connected vehicles. This can help identify construction zones and potential safety hazards to improve traffic flow.
