Utah and Georgia are testing vehicle-to-everything (V2X) technology installed in roads to alert drivers to hazards.
V2X involves equipping cars with radios that emit anonymized data like speed, tire traction level, and windshield-wiper status up to 10 times a second.
Roadside sensors ingest this data for analysis to determine what is happening with individual vehicles and on the road overall, then issue alerts to dashboard screens or smartphones in time for drivers to take action.
Panasonic has partnered with both states’ Departments of Transportation on projects to demonstrate V2X capabilities on its Cirrus cloud computing platform.
Chris Armstrong of Panasonic said V2X can transmit alerts for specific cars and diagnose recurrent problems on stretches of road "so that we can then predict it and prevent it."
