With the technology, fleets can identify the routes and lanes over which their vehicles are most and least fuel-efficient. The GPS sampling density increases when fuel consumption increases or "spikes" and relaxes when fuel consumption decreases or is relatively static.
"Our unique sampling methodology accounts for route and driving changes," says Mike McQuade, Zonar's chief technical officer."For example, if a vehicle is driving in the city with frequent stops and turns, the computer samples much more frequently than if the vehicle is running down a long straight highway."
The fuel consumption monitoring is in addition to the GPS monitoring of latitude, longitude, time and odometer.
