Sleepiness and other driving risks in young adults

This project aimed to investigate the impact of sleepiness and stress on the driving behaviours of young adults (aged 18-25 years). The primary objective was to generate evidence to inform practical and effective interventions to reduce the sleepiness-related road crash risk of young adults. The study sample comprised 83 young adult drivers aged between 18 and 25 years old, sampled from two metropolitan centres in the Australian Capital Territory (ACT) and Queensland (QLD) in Australia. Data were collected prospectively across a 7-day period using a combination of questionnaires, daily sleep diary, stress and driving related diaries, 24-hour ambulatory assessment of both sleep-wake activity (using actigraphy) and stress (using electrocardiography), and in-vehicle monitoring technologies. The project sought to address the following research questions; (1) to determine the impact of sleepiness on on-road driving performance in young adults; (2) to contribute to evidence on young adults’ exposure to driving while sleepy, and (3) to determine interactions between sleepiness and stress related driving risk factors in young adults.
