Abstract
A driver efficiency score is based on defining at least metric, collecting data related to the metric during the driver'"'"'s operation of a vehicle, determining how often the driver'"'"'s deviated from an optimal standard for that metric, and then reducing the efficiency score based on how often the driver'"'"'s deviated from the optimal standard, to express the result as an efficiency score of 100% or less (100% meaning the driver never varied from the optimum). The efficiency score for a specific trip is reported along with a loss in dollars due to an efficiency score of less than 100%. Useful metrics include how often the driver deviated from an optimal RPM range (a sweet zone) for the vehicle being operated, how often the driver operated a vehicle at highway speeds without using cruise control, and how often the driver operated a vehicle in excess of a predetermined maximum speed.
