Motorized 2-3 wheelers death rates over a decade: a global study

Area of Science:

• Public Health
• Transportation Safety
• Global Health

Background:

• Motorized 2-3 wheelers pose high fatality risks due to rider exposure and speed.
• The UN Decade of Action for Road Safety aimed for a 50% reduction in traffic deaths by 2020.

Purpose of the Study:

• To investigate factors influencing motorized 2-3 wheeler death rates.
• To assess if the UN road safety target for reducing fatalities was achieved.

Main Methods:

• Analysis of WHO Global Status Reports on Road Safety (2009-2018).
• Examined variables: death rates, helmet use, law enforcement, GNI per capita, vehicle ratios.
• Utilized a mixed linear model to identify factors affecting death rate changes.

Main Results:

• Global motorized 2-3 wheeler death rates rose by 1.36 (not statistically significant).
• Key factors: GNI, 2-3 wheeler/person ratio, helmet use, and vehicle/person interaction.
• Significant increases in low/middle-income countries; significant decrease in high-income countries.

Conclusions:

• Global mortality for motorized 2-3 wheelers increased, missing UN targets.
• Rising vehicle numbers and economic inequality are critical factors.
• Addressing the global economic gap is crucial for reducing mortality.
