"Travolution"
in [Cars]

From: gpsman on 19 Jun 2010 13:53 Imagine knowing the perfect speed in which to cruise through traffic signals. It would be displayed in your car. Drive the optimal speed and you would never have to stop at a light. That's just the system that Audi is trying out in Germany. The system is being called "Travolution" and it involves having cars communicate with traffic signal to try to take some of the frustration out of city driving. Audi says it has built upon the system that it first tried out in 2006. In 15 test vehicles, the optimal speed for driving easily through the next green light is displayed in the car. The system is rigged to work with 25 traffic signals in Ingolstadt. Audi thinks such a system could reduce waiting times at traffic signals and cut fuel consumption by 17%. The system also makes it possible to pay online when refueling or parking the car, Audi says. The car itself communicates with the stationary equipment at the filling station or parking garage. When the driver confirms the charge, it is automatically debited from the customer's account or credit card. http://content.usatoday.com/communities/driveon/post/2010/06/audis-system-allows-cars-to-breeze-through-traffic-lights/1 http://www.youtube.com/watch?v=9w-QkHuAZrQ ----- - gpsman

This is a fantasy. MOST locations are not conducive to having an "optimal speed" whereby you will "never have to stop at a light". I can think of many places where if drivers reduced speed to avoid a red signal ahead they would waste road capacity and cause unimaginable congestion behind them. On the other hand, many places where there IS an optimal speed (such as the one-way avenues of Manhattan) can be driven optimally with no fancy in-dash technology--just observe the pattern of the signals as they change before you. If you start seeing ped signals flashing the red hand, increase your speed becuase you're looking at stale greens. BTW, I think Manhattan's signals still have mechanical timers. Having said all that, I do think certain locations should have countdown timers for motorists, not pedestrians, so they can adjust their speed accordingly. It wouldn't guarantee a green, but it could avoid unnecessary hard braking. M Keen Ringwood, NJ

DOes anyone really believe that the jerkwater towns that make up the US of A are going to implement this system - espocially since it stands to reason that a systme like this that optimizes traffic flow through the intersections is bound to cut into the red light running and as such the ticket revenue? -- necromancer - ECHM |
