Characteristics and availability of fatal road-crash databases in 20 countries worldwide

INTRODUCTION: This study examined the characteristics and availability of fatal road-crash databases worldwide. METHOD: The study involved two parts. First, the major international road databases were briefly reviewed. Second, the national databases in 20 selected countries were examined. RESULTS: (a) the available international databases of fatal road crashes typically include aggregated data; (b) there is a national database of fatal road crashes in each country examined; (c) all countries provide aggregated crash data, but there are substantial restrictions on the availability of disaggregated data; and (d) overall, the crash data at the accident level are relatively similar, but there are substantial differences in the information at the person level. CONCLUSION: The results imply that international road safety research would greatly benefit from expanded availability of disaggregated fatal crash data worldwide.
