WASHINGTON -- Is sun glare more of an issue in the morning and afternoon? Is earlier darkness making you double take to make sure you're on the right exit ramp?
You may or may not have noticed, but your commute changed significantly this week because the clocks were turned back an hour.
New research suggests that it might take weeks to get used to the new daylight patterns.
Specifically, a study by two Carnegie Mellon University researchers says adjustment to earlier nighttime leads to a 37 percent increase in the risk of pedestrian deaths. The study also says that at 6 p.m. in November, the risk for pedestrian deaths is far greater than at that time in any other month.
The researchers conducted a preliminary study of seven years of federal traffic fatalities and calculated risk per mile walked for pedestrians.
