Most drivers have experienced a speeding fire truck or police vehicle quickly approaching from behind requiring them to quickly react to get out of the way. The danger of these situations is compounded when approaching a busy intersection at high speed when the traffic light is red. For the first responders rushing to a scene, speeding through red lights at intersections is not only dangerous to themselves, but for other nearby drivers and pedestrians.
But new wireless communications technologies being developed and tested by leading companies, including chipmaker Qualcomm Technologies, Applied Information, Audi of America, Commsignia and the city of Peachtree Corners, Georgia, can help make roads by connecting vehicles to nearby vehicles and infrastructure such as traffic lights.
C-V2X, short for “cellular vehicle-to-everything”, provides low latency communications for connecting vehicles to infrastructure without a cellular network or service plan.
