Hottest Electronic Gadgets

We’ve already seen Audi show off a car-to-traffic light communication system, but the automaker has stepped things up considerably with a recent demonstration of its new Travolution system, which not only lets cars communicate with traffic lights, but other cars as well. The basic idea is the same as before: to cut down on pollution and fuel-consumption by reducing idling at stop lights and, in some cases, the need to stop at all. To do that, the system relies on a combination of WiFi and 3G, which currently lets Audi’s 15 test cars communicate with some 150 traffic lights in Ingolstadt, Germany — and with each other to further avoid accidents. What’s more, the system can now also even take control of the vehicles in some instances to prevent them from running a red light, and it will give drivers a heads up about the status of upcoming traffic lights — saying, for instance, if the next light will be red or green if you continue at your current speed. As if that wasn’t enough, the system also helps keep track of traffic jams, and Audi has even thrown in online payment at gas stations and parking garages for good measure. Head on past the break for the complete press release.
