roundabouts, signals save lives

Report cites adding roundabouts, sidewalks, pedestrian crosswalks with signals and median barriers as ways to make roads safer and save lives.

With traffic fatalities on the rise, AAA has produced a list of highway infrastructure changes that could save 63,700 lives and avoid 353,560 injuries over 20 years. In the organization’s list, six key areas account for 95 percent of the safety gains AAA predicts. Chief among them is the implementation of roundabouts.

According to AAA, converting traditional intersections to roundabouts covers 30 percent of the fatality and injury reductions. They do this by drastically reducing the number of ways and locations cars can collide with other cars or pedestrians. What points of collision remain for cars are also less severe, since T-bone or head-on collisions are unlikely.

The other areas of improvement AAA lists are fairly commonsense. Adding roadside barriers and removing roadside objects comprise another 20 percent of safety gains, as do adding sidewalks and pedestrian crosswalks with signals. The remaining safety improvements would come from additional median barriers on highways, shoulder and centerline rumble strips, and wider highway shoulders.
