• A real road driving study was conducted with thirty-three commercial drivers participating in the experiment.
• The impact of continuous driving time on driving performance was examined.
• The effect of rest time on the recovery of the driving performance was studied.
• Drivers' driving performances, such as attention, reaction, are all affected successively after over 2 h of continuous driving.
• The drivers should take a certain amount of rest to recover from the fatigue after over 2 h of continuous driving.
ProblemThis real road driving study was conducted to investigate the effects of driving time and rest time on the driving performance and recovery of commercial coach drivers.MethodsThirty-three commercial coach drivers participated in the study, and were divided into three groups according to driving time: (a) 2 h, (b) 3 h, and (c) 4 h. The Stanford Sleepiness Scale (SSS) was used to assess the subjective fatigue level of the drivers. One-way ANOVA was employed to analyze the variation in driving performance.ResultsThe statistical analysis revealed that driving time had a significant effect on the subjective fatigue and driving performance measures among the three groups. After 2 h of driving, both the subjective fatigue and driving performance measures began to deteriorate. After 4 h of driving, all of the driving performance indicators changed significantly except for depth perception. A certain amount of rest time eliminated the negative effects of fatigue. A 15-minute rest allowed drivers to recover from a two-hour driving task. This needed to be prolonged to 30 min for driving tasks of 3 to 4 h of continuous driving.Practical implicationsDrivers' attention, reactions, operating ability, and perceptions are all affected in turn after over 2 h of continuous driving. Drivers should take a certain amount of rest to recover from the fatigue effects before they continue driving.
