When Kansas State University Professor Sunanda Dissanayake and other researchers studied traffic fatalities in Kansas, they expected to find that more people had died on the roads.
After all, the state had increased speed limits on some highways to 75 miles per hour in 2011. Higher speeds lead to more severe crashes. But they did not expect such a deadly result.
The percentage increase, by how much it got worse, was a big eye-opener, even for us, Dissanayake said in an interview.
