Never wait for a red light again - hit every green. Sounds tempting, doesn't it? Audi is currently testing a device called Travolution that does just that. The in-car gadget searches for wireless signals from nearby traffic lights and calculates how fast the driver should go in order to sail right through.
Special transmitters fitted inside traffic signals send messages to cars in the vicinity letting drivers know of the time remaining until the next green phase. When everything syncs up properly, drivers know how fast to drive in order to make it through before the light turns red.
The system, which was developed by Audi and traffic management experts in the carmaker's German hometown of Ingolstadt, improves synchronization of traffic light networks to reduce stopping times. It also reduces the number of actual stops needed by creating a communications link between cars and the traffic light network.
Reducing stops will reduce fuel consumption and pollution, giving a whole new meaning to going green.
