Car-to-Car (C2C) and Car-to-Infrastructure (C2I) communications enable active safety systems that can have a major impact on crash scenarios, helping reduce fatalities and injuries on the roads. In addition to improving safety, C2I communication holds great potential for intelligent transport system (ITS) management and reducing greenhouse gas emissions from vehicles.

This progress in road safety and traffic management can be realized with the help of applications that warn of hazards such as the potential of a collision ahead, alerting if a nearby vehicle approaching the intersection is at greater risk of colliding, or of upcoming traffic congestion.

By allowing vehicles to reliably interact with each other when travelling even at high-speeds (and also if there is no line of sight between the vehicles), each vehicle can give drivers warnings about potential hazards and allow them to avoid accidents, or even automatically respond to changing driving conditions faster than typical human reaction times. Warnings about traffic blockages ahead also allow early re-routing to avoid traffic congestion.
