“Equipping ITS on these three models will make Toyota the world’s first automaker to bring a driver-assist function that uses a dedicated ITS frequency to market,” Toyota said in a release announcing the decision. The ITS technology uses a frequency of 760 megahertz, which is standardized for Japan, to send and receive information between vehicles and roadway infrastructure. With proper equipment in place, including sensors and cameras on roadways—admittedly, a big caveat—traffic signals will be able to trigger warnings in the dashboard of a vehicle that is approaching a red light but not slowing down. This is just one possible scenario where vehicle-to-infrastructure communication could prevent an accident.
