Motao Zhu from the West Virginia University School of Public Health and Injury Control Research Center, led a group of researchers in the analysis of US travel and traffic data from the years 2008 and 2009.
Worldwide, more than 1.2 million traffic fatalities occur yearly, and the lives of pedestrians account for a third of those lost. In the US, pedestrians make up 12 per cent of deaths from traffic collisions.
Though other studies have shown higher numbers of pedestrian fatalities among men, none had taken other associated factors into consideration.
"Our analysis differed from previous studies as it was the first to examine three main relative contributors to pedestrian death," Zhu said.
"We looked at the amount of daily walking exposure each gender reported, the male and female risk of being involved in a collision while walking and the fatality rates per collision case. No existing research had been this thorough," Zhu added.
The collected data excluded children under the age of five.
According to the US National Household Travel Survey, males and females walked roughly the same distances each day. A sample of police-reported crash data from the same period showed males to be at a slightly greater risk of being involved in a vehicle-pedestrian collision.
Another set of data revealed a far more notable difference: of those pedestrians who were involved in a collision with a vehicle, males were far more likely to die as a result.
When all three factors were analysed collectively, the higher fatality rate led the researchers to conclude that male walkers were 2.3 times as likely to die as the result of a vehicular collision.
Zhu explained that the scientific community already has a good idea why fatalities are far more common among male pedestrians.
"Of course, we already know that a vehicle's speed affects the severity of a person's injuries. Alcohol involvement can also play a large role, and not just with drivers. While most people know not to drive while drunk, it's not safe to walk the streets while impaired, either," Zhu said in a statement.
"Next, we will look at other factors that make males more likely to suffer fatal collisions. Are they taking more risks, such as crossing or walking along highways or other higher speed roads? There are many other factors to consider," Zhu said.
