ROVER Scorecard Metrics

The Rover is programmed to transmit events every 60 seconds while the vehicle ignition is on. Additional events are generated when the Rover detects certain driving behaviors and these are transmitted as they occur, in addition to the 60-second standard reporting. These events are shown below with an asterisk*.

Hard Braking* – A Hard Breaking event is generated each time the Rover detects a deceleration of 6 MPH/second or greater. For example, if you are driving at a speed of 40 MPH and within 1 second slow to 34 MPH (or less) this will generate a Hard Braking event. If you continue to slow at that same rate (or greater), subsequent Hard Braking events will be recorded for each second until the rate of speed reduction is less than 6 MPH/second. The Hard Braking score is a ratio calculated by dividing the total number of Hard Braking events by Total Travel Hours during the Time Interval of interest (ie. weekly in our case).

Rapid Acceleration* – A Rapid Acceleration event is generated each time the Rover detects an acceleration of 6 MPH/second or greater. For example, if you are driving at a speed of 20 MPH and within 1 second accelerate to 26 MPH (or greater) this will generate a Rapid Acceleration event. If you continue to increase your speed at that same rate (or greater), subsequent Rapid Acceleration events will be recorded for each second until the rate of speed increase is less than 6 MPH/second. The Rapid Acceleration score is a ratio calculated by dividing the total number of Rapid Acceleration events by Total Travel Hours over the Time Interval of interest (ie. weekly in our case).

Overspeed –An overspeed event will be generated for each minute the vehicle speed is in excess of the set threshold (75 MPH in our case). For example, if I drive for 5 minutes at 80 MPH, 5 overspeed events will be accumulated in the count. The Overspeed score is a ratio calculated by dividing the total number of Overspeed events by Total Travel Hours over the Time Interval of interest (ie. weekly in our case).

Night Driving – The Rover can determine the time of day your vehicle is in operation. Night driving is an absolute value calculated as the total amount of time (HH:MM) your vehicle was being driven between sunset and sunrise over the Time Interval of interest (ie. weekly in our case). Time of sunset and sunrise is adjusted daily.

Idling – With each Moving event reported while the ignition is on, Rover also reports the speed of the vehicle. An Idle event is generated when the Rover detects a speed of 0 MPH for 3 (or more) consecutive minutes. Idling is calculated as the total amount of time (HH:MM) your vehicle was idling over the Time Interval of interest (ie. weekly in our case).

MPG – Rover captures MPG information from your vehicle with each normal movement report. Its internal GPS locator can also determine the distance traveled between events. The Rover calculates discreet MPG for each specific trip segment then uses a weighted average of these individual points to determine the MPG for the total distance driven. At this time MPG does not
