A new research series published in The Lancet, a top peer-reviewed medical journal, highlights the growing problem of road traffic injuries and lays out some opportunities for preventing injuries and saving lives. An estimated 1.35 million people lose their lives and more than 50 million are injured or disabled as a result of road traffic injuries every year. 

The series, which features research from the George Washington University Milken Institute School of Public Health, comes at the same time as the United Nations General Assembly launches a high-level meeting on global road safety. The series offers a comprehensive analysis of this rising public health threat.

“The death toll from traffic injuries around the world is far too high,” said Adnan Hyder, professor of global health at the Milken Institute SPH. “Despite a United Nations goal to reduce this heavy burden, people everywhere continue to be at great risk of injury and death unless current road traffic strategies are changed to put protections in place.”

Hyder, senior associate dean for research and director of the Milken Institute SPH’s Center on Commercial Determinants of Health, serves as the lead author of an analytic commentary and is the senior author on two other papers published as part of the three-part series. The analytic commentary reviews events that occurred from 1999 to the present and describes 10 challenges that provide an opportunity to make faster progress on road safety.

Two other papers in the series address the issue of road safety around the world. In the first, Junaid Razzak at the Weill Cornell Medical Center, Hyder and their colleagues looked at trauma care for road injuries. They found that approximately 200,000 lives per year could be saved with improved trauma systems in low- and middle-income countries.

In the second paper, Hyder, GW Assistant Research Professor Nino Paichadze, Andres Vecino-Ortiz at the Johns Hopkins University and their colleagues studied four road safety risk factors—speed, drunk driving, helmet and seatbelt use. They found that full implementation of already proven road safety interventions targeting those four main areas could save up to 540,000 lives around the world.

In the United States, a total of about 43,000 lives could be saved by focusing on those four road safety areas, including more than 22,000 lives saved by restricting speed and more than 5,100 with interventions on drunk driving. Another 14,000 and 2,400 lives could be saved with better use of seatbelts and helmets, respectively.

In the analytic commentary, Hyder and his colleagues outline some of the pitfalls that must be overcome to make the roadways safer. They point out that road safety involves many sectors, including health, transportation and other areas, and suggest addressing commercial determinants of road safety. To address road safety the roles of each sector must be clear and one sector should take the lead on developing a strategy, Hyder said.

The authors also recommend reframing road safety in a way that resonates with the public and political leaders. At the same time, there must be the political will to put enough resources toward this problem to address it, Hyder said.

The Lancet Road Safety 2022 series, which includes all three papers and an editorial, will be published June 29 and can be accessed here.
