Deaths and injuries caused by road crashes are critical development and public health issues. Globally, road crashes cause around 1.2 million deaths and 20 million–50 million injuries a year, with Asia accounting for 60% of the toll (Asian Development Bank [ADB] 2005). Road traffic injuries are now the 9th leading cause
of death worldwide. Without new and improved interventions, road traffic injuries are expected to become the 5th leading cause of death globally by 2030 (World Health Organization [WHO] 2013). The global economic cost of road crashes is estimated at $518 billion a year (WHO 2004). The cost to ADB’s developing member countries represented about 2% of their total gross domestic product in 2007, or about $96 billion (ADB 2012).
