Fatigue significantly impacts a driver’s ability to operate a vehicle safely. When a driver is fatigued, their reaction time, attention, and decision-making abilities are compromised. To quantify the effects of fatigue, we can use a mathematical model that relates the hours of sleep a driver has had to their reaction time. Let \( R \) represent the reaction time in milliseconds, and \( S \) represent the hours of sleep. A common model might suggest that reaction time increases linearly with decreased sleep, such that: $$ R = 200 + 50(8 – S) $$ This equation indicates that a driver who has had 8 hours of sleep has a baseline reaction time of 200 milliseconds. For each hour of sleep less than 8, the reaction time increases by 50 milliseconds. For example, if a driver has only had 5 hours of sleep, their reaction time would be calculated as follows: $$ R = 200 + 50(8 – 5) = 200 + 50 \times 3 = 200 + 150 = 350 \text{ ms} $$ This increase in reaction time can lead to dangerous driving situations, as the driver may not respond quickly enough to sudden changes in traffic conditions. Understanding this relationship is crucial for drivers in Idaho, where long stretches of road can lead to fatigue, especially during long trips.
