Filter by:The general aim of the study is to promote safe, economic, and environmental-friendly driving among long-haul truck drivers. To do this, the investigators will conduct an on-road study on i) the relationship of driver sleepiness and stress with driving behaviour and fuel consumption and ii) effectiveness of an educational intervention in mitigating sleepiness at the wheel. The educational intervention is designed to be employed by occupational health care professionals in the future. This solution clearly facilitates the implementation of the intervention into practice if it turns out to be effective. The investigators specified research questions are the following: - Do truck driver sleepiness and stress at the wheel reach levels that affect driving behaviour, fuel consumption and carbon emissions? - What are the sources of sub-optimal arousal at the wheel in truck drivers? - Can truck driver sleepiness be mitigated by an educational intervention, and if yes, does it improve driving behaviour and decrease fuel consumption and carbon emissions as well?
Rationale: Sleepiness behind the wheel is the cause of many traffic accidents. It is claimed that a 15-minute break and consuming an energy drink such as Red Bull® Energy Drink counteracts driver sleepiness. Objective: The objective of this study is to compare driving simulator performance after (1) a 15-minute break with placebo, (2) a 15-minute break with Red Bull® Energy Drink, and (3) continued driving. Study design: A double-blind, placebo-controlled crossover study. Study population: Healthy human volunteers, 21-35 years old. Intervention: Each subject performs 3 test days: 1. 4 hours continued driving 2. 2 hours driving, a 15-minute break + Red Bull® Energy Drink, followed by 2 hours driving 3. 2 hours driving, a 15-minute break + placebo, followed by 2 hours driving Main study parameters/endpoints: Standard Deviation of Lateral Position (SDLP), i.e. the weaving of the car.
