Audi testing bus, school zone vehicle-to-infrastructure system Autoblog 1 hr ago Joel Stocksdale Audi has been a leader in developing vehicle-to-infrastructure technology, with some production Audis capable of receiving information from properly equipped traffic lights about timing. The company is continuing development in these areas, referred to as vehicle-to-everything (V2X), with a system in Georgia that will provide advanced alerts about active school zones and stopped school buses. Research Volvo The automaker is one of a few companies testing the system, the others including Qualcomm, Commsignia, Applied Information, Blue Bird, Alpharetta, Georgia, and the Fulton County School District. The idea is really simple. School zone signs and school bus stop signs are fitted with transmitters that send out signals stating that they're in effect: either the school zone, or the bus being stopped. The signals are sent over 4G LTE and 5G cellular networks on a specially reserved band. When the car, in this case an Audi, picks up that signal, it shows a visual alert and sounds a warning chime to inform the driver.
