Abstract

A system and method of identifying the occurrence of modifiable use conditions related to the safe use of fleet vehicles is described. Modifiable use conditions, such as the speed at which the vehicle is drive, tailgating and an excessive number of lane changes, represent opportunities to reduce unsafe uses of the vehicle. Modifiable use conditions are identified and the occurrence of such use conditions is determined. A user-defined statistical metric for the fleet, or a portion of the fleet, can be determined for each of the modifiable use conditions evaluated. The occurrence of modifiable use conditions related to safety of an individual vehicle, or a group of vehicles, can be compared with a larger group of vehicle, or the fleet, to determine vehicles which correspond to a metric of the fleet. Fleet managers can use this information to modify the use conditions of individual or group of vehicles to provide fuel savings for the fleet.

Claims

1. A method of identifying opportunity to reduce the potential for accidents in a fleet of vehicles comprising:

identifying a plurality of modifiable use conditions that represent an opportunity for accident prevention;

determining the occurrence of events attributable to each of a plurality of modifiable use conditions for a plurality of fleet vehicles;

determining, for each of the plurality of modifiable use conditions, a user-defined statistical metric relating to the occurrence of the events for a plurality of vehicles within the fleet that is attributable to each modifiable use condition; and

determining which vehicles within a fleet represent an accident prevention opportunity by comparing, for each of the vehicles within the fleet, the occurrence of events attributable to each vehicle for each of the plurality of modifiable use conditions with the user-defined statistical metric relating to the occurrence of events of a plurality of vehicles within the fleet that is attributable to each modifiable use condition.

2. The method of claim 1, wherein said plurality of modifiable use conditions comprise driving a vehicle at a speed exceeding a defined speed, applying the brakes on the vehicle, accelerating the vehicle in a sudden, rapid manner, decelerating the vehicle in a sudden, rapid manner, changing lanes with the vehicle, driving the vehicle a set distance behind the vehicle ahead of it, driving the vehicle with tire pressure outside a set range, driving the vehicle with excess weight, and driving a vehicle when the number of driver hours exceeds an established value over a set time period.

3. The method of claim 2, wherein determining the occurrence of events attributable to the modifiable use condition of exceeding a defined speed comprises determining the number of times the speed of the vehicle exceeds a set value over a time period.

4. The method of claim 3, wherein determining the number of times the speed of the vehicle exceeds a set value over a time period is based on values determined from processed data determined from data obtained from sensors on the vehicle.

5. The method of claim 3, wherein determining the number of times the speed of the vehicle exceeds a set value over a time period is based on location information determined from a locator.

6. The method of claim 5, wherein the locator comprises a GPS receiver.

7. The method of claim 3, further comprising determining the amount of time over which the speed of the vehicle exceeds a set value.

8. The method of claim 7, wherein determining the amount of time over which the speed of the vehicle exceeds a set amount is based on speed and time measurements determined from processed data obtained from sensors on the vehicle.

9. The method of claim 7, wherein determining the amount of time over which the speed of the vehicle exceeds a set amount is based on location information determined using a locator.

10. The method of claim 2, wherein determining the occurrence of events attributable to the modifiable use condition of applying the brakes on the vehicle comprises determining the number of times the vehicle brakes are applied over a set time period.

11. The method of claim 2, wherein determining the occurrence of events attributable to the modifiable use condition of accelerating the vehicle comprises determining the number of times the vehicle accelerates at a rate greater than a set rate over a set time period.

12. The method of claim 2, wherein determining the occurrence of events attributable to the modifiable use condition of decelerating the vehicle comprises determining the number of times the vehicle decelerates at a rate greater than a set rate over a set time period.

13. The method of claim 2, wherein determining the occurrence of events attributable to the modifiable use condition of changing lanes while driving the vehicle comprises determining the number of times the vehicle changes lanes over a set time.

14. The method of claim 13, further comprising determining the number of times the vehicle changes lanes over a set time with or without using turn indicators.

15. The method of claim 2, wherein determining the occurrence of events attributable to the modifiable use condition of driving the vehicle a set distance behind the vehicle ahead of it comprises determining the number of times the vehicle is within a set distance of the vehicle ahead of it.

16. The method of claim 1, further comprising comparing the plurality of use conditions for a plurality of vehicles in the fleet against each other to determine the relative opportunity to reduce the potential for accidents.

17. The method of claim 1, further comprising evaluating the occurrence of events for each of a plurality of modifiable use conditions for each fleet vehicle over time.

18. The method of claim 1, further comprising evaluating the occurrence of events for each of a plurality of modifiable use conditions for a plurality of fleet vehicles over time.

19. The method of claim 1, further comprising adjusting at least one of the use conditions in a vehicle.

20. The method of claim 1, further comprising adjusting at least one of the use conditions for the fleet of vehicles.

21. A system for identifying vehicle safety in a fleet of vehicles comprising:

a computer; and

a data store operably connected to the computer, the data store comprising at least one data set of information concerning the operational condition of the vehicle collected from at least one individual vehicle, and at least one data set of vehicle positioning data collected from the same individual vehicle as the first set of information;

wherein the computer being adapted to calculate the occurrence of events providing at least one opportunity to reduce potential accidents, and to report at least one opportunity to reduce potential accidents.
