Relationship between Fatigue, Sleepiness, and Crash Risk

This project is looking at the accuracy with which drivers can judge their own fatigue and declining driving performance in both a driving simulator and on-road using an instrumented vehicle. Current road safety advice to drivers tells them to 'take a break when you feel tired'. Unfortunately, there is some doubt over whether people are very accurate at determining when they are too tired to drive. The results of this project will help to develop better strategies for managing driver fatigue.
