The effect of three low-cost engineering treatments on driver fatigue: A driving simulator study

► We implemented 3 engineering measures in a driving simulator study on fatigue. ► Fatigue was measured by observing changes in PERCLOS and lateral deviation. ► Both measures were a good indicator of fatigue in our drivers. ► PERCLOS reduced after all three treatments, with no difference between treatments. ► Roads prone to fatigue related accidents may benefit from employing such treatments.
