A study done by NAVTEQ, a navigation system data provider, found that using GPS systems with real-time traffic information can save drivers four days a year of driving time and can cut emissions by 21 percent.
NAVTEQ collected data on driving times of three types of drivers in Dusseldorf and Munich, Germany: drivers without in-vehicle navigation, drivers with static navigation and drivers with real-time traffic navigation. In total, the study reflects data from 2,100 individual trips, 2,000 km and 500 hours of driving. The study showed the group with the real-time traffic alerts spent 18 percent less time getting to their destinations than the other two groups.
Over the course of a year, those savings add up to four days of travel time. The study also states that the reduction in distance traveled and increase in fuel efficiency caused by choosing less congested routes would amount to a decrease in emissions of .79 metric tons per driver, or 21 percent per year. They calculate that U.S. drivers would see the same savings as German ones.
Since this study was coordinated by a company that has a heavy interest in GPS sales, it's important to note that you don't need a GPS unit to get real-time traffic information. Many smart phones are equipped with mapping software that gives you the same information and you can always check out your route online before leaving the house.

of course the study was contrived to favor the sponsor's product. but the numbers are entirely plausible for a congested region. here in Seattle, choosing the right bridge based on this sort of data can easily halve my travel time, with corresponding reduction of fuel consumption.
Efficient transit will indeed have more benefit, but devices like these are low-hanging fruit, which don't interfere with the larger goal in *any way*. why insult it?

The young Romanian Cartier Replicagreat quality replica discount replica watches director Christian Mungiu receiving the Palme d'Or at Cannes 2007, for his film 4 months, 3 weeks and 2 days. The Palme d'Or has been designed and created by Chopard. The paradox, and the merit, of the Cannes replica watches storeFilm Festival, is that the films entered into the cheap replica watches replica watches competition are the artiest, the most disturbing, the most engaging, and the most innovative. This is evidenced by the fact that, this year, the prestigious Palme d'Or was awarded to a small-budget film, by an unknown author, from a distressed country, Romania. Yet in terms of marketability, this film is most likely a featherweight.
