Abstract

In a system and method for assessing and modifying fatigue, an input device receives current work-rest pattern and/or sleep data from an individual. A data aggregation and processing platform combines the current work-rest pattern and/or sleep data with previous data related to the individual to generate a fatigue assessment result, a diagnostic assessment result, and a corrective intervention result. At least one output display outputs the fatigue assessment result, diagnostic assessment result and corrective intervention result in a user-readable format to a user. The user uses this information to revise the work-rest pattern to reduce or control future fatigue risk.

Claims

1. A fatigue risk assessment and modification system, comprising:

an input device that receives at least one of current work-rest pattern and sleep data from an individual;

a data aggregation and processing platform that combines the at least one of the current work-rest pattern and the sleep data with previous data related to the individual to generate at least one of a fatigue assessment result, a diagnostic assessment report that includes a causation of excessive fatigue risk, and a corrective intervention plan for reducing future fatigue risk; and

at least one output display that outputs the at least one of the fatigue assessment result, the diagnostic assessment report, and the corrective intervention plan in a user-readable format to a user.

2. The system of claim 1, wherein the input device generates a current record from the at least one of the current work-rest pattern and the sleep data related to the individual, and wherein the data aggregation and processing platform stores the current record.

3. The system of claim 1, further comprising a plurality of input devices that receives at least one of current work-rest pattern and sleep data from a plurality of individuals, wherein the data aggregation and processing platform receives the at least one of the current work-rest pattern and the sleep data from each input device and generates at least one of a fatigue assessment result, a diagnostic assessment report that includes a causation of excessive fatigue risk, and a corrective intervention plan for reducing future fatigue risk for each individual.

4. The system of claim 1, further comprising a position verification device that verifies the at least one of the current work-rest pattern and the sleep data.

5. The system of claim 4, wherein the position verification device determines a first location of the individual at successive intervals of time and determines whether the individual has moved to a second location by comparing locations.

6. The system of claim 1, further comprising an engine control module that collects data on movements of a machine that is operated by the individual and verifies the at least one of the current work-rest pattern and the sleep data by determining whether the machine has moved.

7. The system of claim 1, wherein the at least one of the current work-rest pattern and the sleep data is collected from worker logs and manually entered into the input device.

8. The system of claim 1, wherein the at least one of the current work-rest pattern and the sleep data is collected from electronic logs and electronically entered into the input device.

9. The system of claim 1, wherein the at least one of the current work-rest pattern and the sleep data is transmitted from the input device to the data aggregation and processing platform through a communications network.

10. The system of claim 9, wherein the communications network is one of a satellite communications network, a wireless network, a telecommunications network, and a data communications network.

11. The system of claim 1, wherein the data aggregation and processing platform comprises a fatigue risk processor that computes the at least one of the fatigue assessment result, the diagnostic assessment report, and the corrective intervention plan from the at least one of the current work-rest pattern and the sleep data.

12. The system of claim 11, wherein at least one predictive model is applied to the fatigue risk processor to compute the at least one of the fatigue assessment result, the diagnostic assessment report, and the corrective intervention plan.

13. The system of claim 12, wherein the predictive model complies with a Fatigue-Risk-Informed Safety-Performance-Based (FRISPB) paradigm.

14. The system of claim 12, wherein the predictive model is at least one of a fatigue risk model and a driver profile model, the fatigue risk model for computing the fatigue assessment result as a fatigue risk score, the diagnostic assessment report, and the corrective intervention plan, and a driver profile model for computing a driver profile result that includes other non-fatigue causes of risk.

15. The system of claim 14, wherein the fatigue risk score and the driver profile result are combined to generate a driver risk assessment.

16. The system of claim 15, wherein the driver risk assessment is output to the output display.

17. The system of claim 1, wherein the user uses the fatigue assessment result to control fatigue risk in the individual using a diagnostic assessment report on the causation of excessive fatigue risk, and a corrective intervention plan to reduce future fatigue risk.

18. The system of claim 1, wherein the individual is a commercial motor vehicle driver.

19. The system of claim 18, wherein the fatigue risk assessment system is installed in a machine in a vehicle that is operated by the driver.
