A Minnesota Department of Transportation study out last year showed that roundabouts are safer for motorists because they help slow down traffic. That results in far fewer crashes that involve serious injuries or deaths than traditional intersections controlled by stop signs or stoplights.
While that might be true for vehicles, what's the situation for pedestrians?
Research out of Europe indicates that, on average, converting conventional intersections to roundabouts can reduce pedestrian accidents by about 75 percent.
Single-lane roundabouts, in particular, report substantially lower pedestrian crash rates than comparable intersections with traffic signals.
None of that brings comfort to Drive reader Ross, who is about to get two of the circular interchanges near the senior center in Richfield where he lives. This summer, Hennepin County and the city of Richfield are teaming up to remove traffic lights and put in roundabouts on 66th Street at Nicollet and Lyndale avenues.
That is a big concern, especially for the many seniors living nearby who would like to be able to cross streets, he said. He points down the road to 66th Street and Portland Avenue, which he calls "a nightmare for anyone on foot."
Crosswalks have been placed immediately before drivers enter the circle. A sign tells motorists that it is a state law to stop for pedestrians in a crosswalk.
The trouble with that, he says, is "you are looking for an opening and not paying attention to the crosswalk in front of you."
