Green GPS System Finds Most Fuel Efficient Driving Routes
An all-new Green GPS system, developed by computer scientists at the University of Illinois, is able to calculate the most fuel-efficient driving routes, saving as much as 13 percent over other routes in initial tests.
“Unlike existing Internet services, such as Google Maps and MapQuest, which provide either the fastest or the shortest route between two points, a Green GPS system collects the necessary information to compute … the most fuel-efficient route” explained Ph.D. candidate Raghu Kiran Ganti, one of three student researchers working with Principal Investigator and Associate Professor of Computer Science Tarek Abdelzaher. “The most fuel-efficient route between two points may be different from the shortest and fastest routes.”
For example, taking the fast route on a freeway may not be economical because fuel consumption increases in a non-linear manner with speed, or because the route is longer. Similarly, the shortest route, over city streets, may be objectionable because of downtown congestion and traffic.
