Connected-Car Technology Sought to Counter Rising Traffic Deaths

Transportation officials and industry are looking to speed the deployment of technology that would allow cars to communicate with other vehicles, infrastructure, and pedestrians, but challenges remain around regulatory uncertainty and wireless interference. Proponents see the technology as a way to counter rising traffic deaths. Roughly 43,000 people died in crashes last year, the most since 2005, according to federal estimates.

The technology, called V2X or vehicle-to-everything, aims to allow cars to transmit information about speed and location, as well as provide drivers with real-time advisories on road conditions and information on pedestrians.
