The IRTAD (International Traffic Safety Data and Analysis Group) Road Safety Annual Report 2017 provides an overview of road safety performance for 2015 in 40 countries, with preliminary data for 2016, and detailed reports for each country. It includes tables with cross country comparisons on key safety indicators. The report outlines the most recent safety data in IRTAD countries, including detailed analysis by road user, age group and type of road. It describes the crash data collection process in IRTAD countries, the road safety strategies and targets in place, and information on recent trends in speeding, drink-driving and other aspects of road user behaviour. The 2017 edition of the IRTAD Road Safety Annual Report puts special emphasis on road safety for an ageing population, which represents a growing concern in many countries.
