The pedestrian deaths occurred mostly when it was dark and mostly on roads designed to funnel urban or suburban traffic onto freeways, the institute says. The crashes generally occur where there are no intersections or poorly designed crosswalks that tempt pedestrians to dash across multiple lanes of swiftly moving vehicles. The crashes often involved SUVs or vehicles with a lot of horsepower, which suggests that many of the crashes also involved excess speed.
“This analysis tells us that improvements in road design, vehicle design and lighting and speed limit enforcement all have a role to play in addressing the issue,” IIHS President David Harkey said in a statement.
The report — which analyzed federal crash data from 2009 to 2016, along with details related to the type of roadway, vehicle and other factors — says 5,987 pedestrians died in crashes in 2016, or about 16 percent of all traffic deaths. More than half occurred in areas most people would consider to be either city or suburb in type. The biggest increase (67 percent) occurred on the arterial roadways, with 50 percent at non-intersections and 56 percent in the dark, the institute says.
In addition to better roadway and crosswalk design, the institute says higher standards for headlights could reduce pedestrian deaths. Since 2016, the institute has issued ratings on headlights. Though many vehicles now have running lights, they are intended to make the vehicles more visible during the day, while many models have headlights that do not perform well when it’s dark, IIHS spokesman Russ Rader said.
“Vehicle headlights used when it’s dark are not performing as well as they could. Our testing shows that some vehicles have headlights on low beams that allow drivers to see twice as far down the right-side of the road on a straightaway than headlights on other vehicles,” Rader said in an email. Since 2016, the institute has issued ratings on headlights.
