SEAT Leon talks to traffic lights
SEAT has trialled a technology which enables its Leon vehicles to talk to traffic lights so the driver knows when they’re about to change colour. The new SEAT Leon was connected to Barcelona’s traffic light infrastructure as a test to look at ways of improving road safety, traffic flow and environmental efficiency.
When the Leon approached a traffic light, an alert appeared on the screen saying whether it will be red, green or yellow when the car arrives.
It had calculated how far away the car was from the lights and the speed it was travelling at after real-time traffic data was sent into a ‘cloud’ which shares data with the Leon’s infotainment.
The process is known as V2I, or ‘Vehicle to Infrastructure’, where connected cars can interact with infrastructure via an internet connection or wireless local area network, and it takes just 300 milliseconds.
