The number of pedestrians killed on U.S. highways last year is expected to remain largely unchanged from 2013, based on preliminary data.
But a study by the Governors Highway Safety Association says Michigan's pedestrian deaths rose significantly.
In the first six months of 2013, 47 pedestrians lost their lives on a Michigan road. That number was 66 for the same time period in 2014.
Researcher Allan Williams says it's not clear why, although in general, the risk factors are well known.
Nearly 40% of pedestrians who are killed on a road are inebriated. Distracted walking is on the rise, as more and more people walk while texting or reading emails on their smartphones.
