Vehicle-to-Vehicle (V2V) Communication Technology/ What is Vehicle-to-Vehicle (V2V)?

The Government of India is preparing to roll out Vehicle-to-Vehicle (V2V) communication technology by end of 2026.

About Vehicle-to-Vehicle (V2V) Communication Technology:

• Vehicle-to-vehicle communication technology is a wireless systemthat allows vehicles to directly exchange safety data without using mobile or internet networks.
• Objective: The primary objective is to lower the risk of collisionsand chain accidents by providing advance warnings about sudden traffic changes.
• Working mechanisms
  • Internal communication unit:Vehicles will be fitted with an internal communication unit that can transmit and receive signals from other vehicles on the road.
  • Continuously shares details:While moving, each vehicle continuously shares details such as position, speed, direction, and braking status with surrounding vehicles.
  • Dedicated radio frequency: This exchange uses a dedicated radio frequency authorised by the Department of Telecommunicationsand does not depend on mobile or internet services.
  • Immediate alerts: When the system identifies riskslike sudden deceleration, close distance, or vehicles approaching from blind spots, it immediately alerts the driver.
  • In vehicles equipped with Advanced Driver Assistance Systems,these alerts can support timely automatic responses.

• Key features
  • All-round communication: The technology enables vehicles to exchange information from the front, rear, and sides, ensuring complete situational awareness.
  • Hidden hazard alerts: It provides immediate warnings about dangers that are not directly visible to the driver.
  • Low-visibility safety: The system reduces accident risks during foggy or poor visibility conditions on highways.
  • Network-free integration: It works without mobile networks and strengthens the performance of existing driver assistance systems.
• Concern: The technology requires large-scale adoption to be effective, adds extra cost for vehicle buyers, operates within a limited range, and initially provides only warning-based assistance.
