Road deaths are declining around the world, even as more than 1 billion additional vehicles have been added since 2011. The U.S., however, is not following this trend, highlighting shortcomings in how we measure and approach road safety. Other countries are taking different strategies, and those that have produced systemic changes in how vehicles, roads, and land use are designed are seeing better results.

Bigger isn’t always better: The hidden costs of larger vehicles
Vehicles in the U.S. have gotten much larger over the past few decades, and research suggests that this shift has had far-reaching consequences, making roads more dangerous for everyone while increasing emissions and other environmental impacts. A recent New York Times analysis estimates that between 200 and 400 pedestrian deaths each year could have been avoided if cars had remained roughly the same size as they were 25 years ago. While the rise of SUVs and pickup trucks is often treated as the result of a cultural shift or consumer preference, researchers argue that policy has also helped shape today’s vehicle market. If policy helped encourage this shift, it could also help reverse it.
Vehicle hoods are now four inches taller and 22 percent more deadly for pedestrians
Vehicles keep getting larger and heavier. Increasing a vehicle’s size not only increases emissions, it also has important implications for pedestrian safety, increasing the risk of injury and death on the road. Many studies have looked at the predominant factors that heighten risk for pedestrians. A new study from the University of Hawaii analyzes both crash data and physical vehicle measurements, rather than focusing on vehicle types, to determine a leading factor in pedestrian death rates: the front-end height of a vehicle.
