New GPS Highway System Takes Control of Your Car...Makes Road Trips Easier?
"Sartre" is the shortened version of "Safe Road Trains for the Environment" and, as the name implies, is based on using a long group of vehicles to help traffic move more efficiently. It all begins with a lead vehicle, which is basically a pre-equipped car or truck that can communicate with other vehicles outfitted with the system. They will travel the highways and be able to take control of other vehicles, with the permission of the driver of course, and then essentially lead the pack.
Using this system would allow up to nine vehicles to travel at a fairly constant speed with relatively little distance between them. When one of the vehicles is approaching a desired exit, it will signal its intention and then wait for a small gap to form. Once the other vehicles have made sufficient room to leave the "platoon," you simply take control of your vehicle and leave the highway.
The system is being tested on a handful of test tracks across Europe. The testing will eventually make its way to the public road system, but only after proving its reliability.Auto Blog
