Patent ID: 8306731

Claim:
A method of representing an efficiency of a vehicle, comprising: electronically receiving, at a computing device, a plurality of vehicle positions as a function of time; determining, by the computing device, at least one vehicle status as a function of time, wherein the status is based at least in part upon the vehicle position as a function of time; determining, by the computing device, at least one geographical area associated with a selected vehicle status over a selected time interval; calculating, by the computing device, an efficiency of the vehicle using at least a total time the vehicle is determined to be in the selected vehicle status over the selected time interval; and providing, by the computing device, a map upon which is superimposed a geometric figure representative of the geographic area, wherein the geometric figure is further provided with a visual indicator of the efficiency of the vehicle wherein determining the geographic area comprises; identifying a maximum latitude, a maximum longitude, a minimum latitude, and a minimum longitude of the plurality of vehicle positions when the vehicle is in the selected status over the selected time interval; identifying two spatial points comprising the maximum latitude, maximum longitude and the minimum latitude, minimum longitude; and constructing a rectangle having the two spatial points as opposite corners.
