The best way to prevent these accidents from continuing is by treating sleep apnea.
The conclusion to the studies and evaluation of these accidents is that preventing sleep apnea related accidents requires attention from each transit authority medical department to ensure that transportation operators are diagnosed and treated.
It is essential for the health of individual operators to have sleep apnea screened as part of their overall medical care. Several of the engineers in the railroad accidents did complain of fatigue or sleepiness on the job, and they needed to be further evaluated to see why they felt that way in the first place. In all cases, it was sleep apnea that cause their accidents. Sleep apnea can be successfully treated if it is diagnosed correctly.
