Second downward trend in global road traffic deaths.

Area of Science:

• Public Health
• Epidemiology
• Transportation Safety

Background:

• Global road traffic deaths represent a significant public health concern.
• Previous declines in road traffic fatalities were observed in the 1970s in developed nations.
• Understanding trends in road traffic mortality is crucial for effective safety interventions.

Purpose of the Study:

• To identify and characterize a second downward trend in the global rate of road traffic deaths.
• To analyze patterns associated with declining road traffic fatalities in countries exhibiting this trend.

Main Methods:

• Statistical analysis of road traffic death rates per 100,000 population.
• Application of smoothing functions to scatter plot data for 16 identified countries.
• Examination of trends spanning the period 1990-2021.

Main Results:

• A second wave of declining road traffic death rates was detected in 16 countries from 1990 to 2021.
• This contrasts with the first wave of declines noted in the 1970s in Western Europe, the USA, and Australia.
• The study identified specific patterns within these downward trends.

Conclusions:

• A notable shift from an upward to a downward trend in road traffic deaths has occurred in 16 countries.
• This represents a significant second wave in the global reduction of road traffic fatalities.
• The findings highlight evolving patterns in road safety and mortality.
