When it comes to design, we must also consider the deadly impacts of ever-larger vehicles - Smart Growth America

While Dangerous by Design 2022 focuses on street design, the increasing size and weight of personal vehicles are also having an impact on the steadily increasing number of people struck and killed while walking. In addition to designing safer streets, improving vehicle design along four main criteria is also critical for reducing pedestrian fatalities.

Weight: Heavier vehicles like trucks and SUVs, which make up a growing share of both the current fleet and new vehicle sales each year, are more dangerous to both pedestrians and people inside of othervehicles. Their increased weight, combined with higher speeds, increases the likelihood of death. A2015 studyby the Department of Transportation found that “pedestrians are 2–3 times more likely to suffer a fatality when struck by an SUV or pickup truck than when struck by a passenger car.” 

Size: Vehicle size can also increase the likelihood of a pedestrian fatality in what should be obvious ways. Pedestrians struck in the lower body by a sedan are more likely to roll over the vehicle and survive the crash. Those struck directly in the pelvis, chest, or head by today’s much taller vehicles aremore likelyto die upon impact or be pulled under the vehicle and crushed by the wheels. 

Visibility: Taller vehicles decrease the visibility of people walking, increasing the likelihood of a crash. Today’s typical passenger pickup trucks and SUVs have significant front blind spots caused by large hoods and bumpers thatcan eclipse most pedestrians, especially those who are shorter, like children. Large a-pillars (the frame of the car between the windshield and the driver and passenger windows) are wider and larger on trucks and SUVs, contributing to lower visibility while making turns. In fact, when pedestrians are killed by a turning vehicle, the driver isfar more likelyto be behind the wheel of an SUV or pickup truck. So if someone walks out into a crosswalk in front of or near a pickup truck or SUV, even if the pedestrian has the right of way, the driver is less likely to see the pedestrian, increasing the odds of a deadly crash. Like the roadway design practices discussed in this report, these vehicle designs set drivers up to fail—to not see people walking until it is too late—and both people walking and drivers pay the price.

Psychology and marketing: Low visibility and high weight create an intimidating and powerful-looking vehicle—a fact not lost on the drivers of these vehicles and leveraged by automobile manufacturers and their marketing efforts. Advertising campaigns forFord,Hummer, andJeeprely on militarized language that contributes to aparamilitary aestheticand aggressive driving mentality. 

The evolution of each of these four design elements is producing more danger, and is likely a major culprit in our growing rate of traffic fatalities.Truck sales are increasingas a percentage of the U.S. vehicle market share. Front blind zonescontinue to grow. Electric vehicles, which are taking up an ever-larger share of the passenger car market, aremuch heavierthan cars with internal combustion engines. Is anyone in charge of protecting the safety of the traveling public paying attention?

The pending update to theNew Car Assessment Program(NCAP), a federal program that rates new cars on safety metrics, had the opportunity to penalize vehicles that perform poorly on the above metrics. But USDOT decided to focus on pedestrian-sensing technology in new vehicles. While technology can help avoid some crashes—and the fact that NCAP finally mentions pedestrians at all is unfortunately an improvement—technology alone will do nothing to make crashes that do occur with these vehicles any less deadly for pedestrians. Passenger vehicles that are proven to increase the likelihood of a pedestrian fatality should not receive five-star safety ratings. NCAP must change this or these ratings willremain uselessto slow or stem thetide of pedestrian fatalities. And safety ratings alone are not sufficient, since they simply provide information. We must update vehicle performance standards to require safer vehicle design for pedestrians. America Walks,among others, has beenbeating the drumon this,as should everyoneinterested in pedestrian safety.
