Regulatory and road engineering interventions for preventing road traffic injuries and fatalities among vulnerable (non-motorised and motorised two-wheel) road users in low- and middle-income countries

The purpose of this review will be to establish what is known about the effects and effectiveness of enforcement of traffic laws and regulations and road engineering interventions for prevention of injury (fatal and non-fatal) to non-motorised road users and motorised two-wheel road users in low-income and middle-income countries.

This is a protocol.
