A Seminar on the Impact of Distracted Driving and Sleepiness on Road Safety, organised by the International Transport Forum, took place in Paris on 15 April 2014, during the Transport Research Arena Conference. The objectives of the Seminar were to discuss latest research work in ITF countries to better understand the impact of distraction and fatigue on driving performance and road safety and identify measures that can help in the short and longer term in mitigating the effects on crash occurrence. The Seminar involved key stakeholders, including researchers, policy advisors, industry, police, user associations to highlight latest knowledge on these emerging road safety issues, and discuss forthcoming developments in regulation, vehicle and IT technology that have an impact on distraction and fatigue. All presentations are now available.
