Saving lives through road safety risk factor interventions: global and national estimates

Area of Science:

• Public Health
• Transportation Safety
• Global Health

Background:

• Road mortality is a significant cause of death in low- and middle-income countries.
• Urgent data is needed for resource allocation to achieve Sustainable Development Goal (SDG) 3.6.
• This study addresses the need for evidence-based road safety interventions.

Purpose of the Study:

• To estimate the number of lives saved by implementing interventions targeting key road injury risk factors.
• To provide country-specific data for prioritizing road safety efforts.
• To inform strategies for achieving SDG 3.6.

Main Methods:

• Systematic review of evidence-based preventive interventions for road injury mortality.
• Analysis focused on four main risk factors: speeding, drink driving, helmet use, and seatbelt/child restraint use.
• Country-specific estimates generated using literature review variables and country-level data (GDP per capita, population density, government effectiveness) for 185 countries.

Main Results:

• Implementing interventions for the four main risk factors could prevent 25-40% of global fatal road injuries.
• Speeding interventions could save approximately 347,258 lives annually.
• Drink driving interventions could save at least 16,304 lives, seatbelt interventions 121,083 lives, and helmet interventions 51,698 lives annually.

Conclusions:

• Evidence-based road safety interventions targeting major risk factors are highly effective in reducing global road fatalities.
• Country-specific estimates highlight the potential impact and scalability of these interventions.
• The findings provide crucial evidence for prioritizing road safety initiatives and advancing SDG 3.6.
