Road traffic accidents are the main cause of death for people between 5 and 20 years of age worldwide, with approximately 1.35 million road traffic deaths in 2016. While the global rate for road traffic deaths is around 18 per 100 000 population, there is great disparity by income, with rates more than three times higher in low and middle income countries and territories than in the world’s high income countries and territories (WHO, 2018[42]). South-East Asia is one of the most affected regions, with 20.7 road traffic deaths per 100 000 population. Western Pacific countries, however, have a rate of 16.9 road traffic deaths per 100 000 people, lower than the global average. Generally, speed contributes to about half of road deaths in high income countries and territories, whereas in middle and low income countries speeding accounts for 37% and 13% of the deaths respectively. The burden of road traffic deaths falls disproportionately on vulnerable road users as more than half of deaths are among pedestrians, cyclists and motorcyclists. The proportion of deaths among these vulnerable road users is higher in emerging economies where urbanisation and motorisation accompany rapid economic growth. In many of these countries, necessary infrastructural developments, policy changes and levels of policy enforcement have not kept pace with vehicle use (WHO, 2018[42]). The UN SDGs includes a target aiming to halve the number of global deaths and injuries from road traffic crashes by 2020 (SDG 3.6).
