Road traffic injuries: a major global public health crisis.

Evidence suggests that the present and projected global burden of road traffic injuries is borne disproportionately by countries that can least afford to meet the health service, economic and societal challenges. Although the evidence base on which these estimates are made remains somewhat precarious in view of the limited data systems in most low- and middle-income countries, these projections highlight the essential need to address road traffic injuries as a public health priority. Most well-evaluated effective interventions do not focus directly on efforts to protect vulnerable road users, such as motorcyclists and pedestrians. However, these groups comprise the majority of road traffic victims in low- and middle-income countries, and consequently the majority of road traffic victims globally. Responding appropriately to the disparities in available evidence and prevention efforts is necessary in order to address this global public health crisis comprehensively.
