| Summary: | Train accidents are mostly caused by the negligence of the train drivers who
operate the train in fatigue, sleepy, and lack of attention condition. These
conditions are caused by sleep deprivation before duty. This research aimed to
quantify the factor of the sleep duration, fatigue, sleepiness level, and lack of
attention on the performance of train drivers while driving in a train simulator
with monotonous routes. The performance of train drivers is a latent variable
explained by the indicator of speeding (total of speed limit violations), thus the
performance is better to the smaller score. Structural Equation Modeling is used
to model the quantity of the factors. The result showed that the performance of
train drivers is affected by the factors of sleep duration, sleepiness level,
attention, and fatigue with the path coefficient of -0.90, 0.38, -0.12, and 0.05,
respectively, which means sleep duration is the most influencing factor on the
performance of train drivers. These four factors can explain the performance of
the driver by 96.2%. |
