DETROIT (AP) - A report from a safety organization says the number of pedestrians killed on U.S. roads last year was the highest in 28 years.

Using data reported by states, the Governors Highway Safety Association estimates that 6,227 pedestrians were killed last year. That's up 4 percent from 2017 and 35 percent since 2008.

The association blames the increase on factors that include distracted or impaired drivers, additional people walking to work, and more SUVs on the road, which cause more severe injuries in collisions with people on foot.

It also says most deaths happen on local roads at night and away from intersections, and it called for safer road crossings. Night crashes accounted for more than 90 percent of the increased deaths over the past decade.
