2010 CRC Showcase - Safety & Security - Next Generation Fatigue Models R2.110
0 likes305 views
Next generation fatigue models aim to more accurately assess fatigue risk. Researchers are collecting sleep, work and activity data from 300 rail employees over 4000-5000 days to enhance fatigue modeling algorithms. The goal is to develop a next generation fatigue modeling tool that considers different employee profiles and provides a fatigue indicator for working times. This could lead to a more scientifically defensible approach to fatigue management and a safer, more efficient railway.
