The methodology used for this survey was developed in consultation with an expert committee of road safety researchers and practitioners. Data collection was carried out using a self-administered questionnaire, the content of which was based on the recommendations of the World report on road traffic injury prevention.
The methodology used involved the identification of a National Data Coordinator in each country who facilitated a consensus meeting involving a multisectoral group of up to eight road safety experts. Based on consensus, one final country questionnaire was submitted to WHO following government clearance. Final data were received from 178 participating countries and areas which account for over 98% of the world's population.
