☆ Drivers of boxy SUVs and pickup trucks are more likely to kill pedestrians, study finds
  + stars: | 2023-11-14 | by ( Peter Valdes-Dapena | ) edition.cnn.com   time to read: +4 min
Researchers at the institute looked at records of almost 18,000 incidents in which vehicles struck pedestrians. Tall front ends are common among full-size trucks and SUVs but they aren’t exclusive to very big vehicles. In general, vehicles with box-shaped front ends, even when they’re only medium height, are roughly 26% more likely to kill a pedestrian, according to the IIHS. NHTSA has also proposed adding pedestrian safety tests to its regimen of crash tests and other safety measurements for new vehicles. But automakers should also consider pedestrian safety in the design of their vehicles, IIHS president David Harkey said in a statement.

☆ Vehicles With Higher, Vertical Front Ends Raise Risks for Pedestrians
  + stars: | 2023-11-14 | by ( Associated Press | Nov. | At A.M. | ) www.usnews.com   time to read: +2 min
Motor vehicles with higher, more vertical front ends raise risks for pedestrians, according to a highway safety organization. But among vehicles with hood heights between 30 and 40 inches, a blunt, or more vertical, front end increases the risk to pedestrians. Vehicles with hood heights of more than 40 inches and blunt front ends angled at greater than 65 degrees were 44% more likely to cause fatalities. “There’s no functional benefit to these massive, blocky fronts.”While sloping front ends did not reduce the risk posed by vehicles with the tallest hoods, they did make a difference for vehicles with hood heights of 30 inches to 40 inches. There was a 25% increase in the risk of a fatality for vehicles with flat hoods — those with angles of 15 degrees or less — compared with vehicles with more sloping hoods.

☆ The US went from having 356 to 10,000 roundabouts in 2 decades, and a transportation engineer explains why they're so much better than traffic lights

Experts say that this road feature reduces traffic and car crashes. I research transportation engineering, particularly traffic safety and traffic operations. The birth of the modern roundabout came with yield-at-entry regulations, adopted in some towns in Great Britain in the 1950s. The first modern roundabout in the U.S. was built in Summerlin, on the west side of Las Vegas, in 1990. Ever since, the construction of modern roundabouts in the U.S. has picked up steam.
