According to a 2004 report from the World Health Organization, 22% of all injury mortality worldwide was from road traffic injuries in 2002, and without "increased efforts and new initiatives" casualty rates would increase by 65% between 2000 and 2020. The report identified that the speed of vehicles was "at the core of the problem", and recommended that speed limits be set appropriately for the road function and design, along with the implementation of physical measures related to the road and the vehicle, and increased effective enforcement by the police. Road incidents are said to be the leading cause of deaths among children 10–19 years of age (260,000 children die a year; 10 million are injured).
