The City Of Rio Rancho publishes more information about the safety of roundabouts.
Reduction in fatalities, reduction in injuries, reduction in all crash types, reduction in the severity of a crash if it does occur, slower speeds which allow drivers more time to react to a situation, and generally safer for pedestrians because they need only cross one direction of traffic at a time at each approach
The city of Rio Rancho has been putting in roundabouts all over the place and installing “road diets” which I didn’t know what they were called. I learned about them in a Rio Rancho Observer article.
Road diets, according to the United States Department of Transportation, are often conversions of four-lane, undivided roads into three lanes. The fourth lane may be converted to bicycle lanes, sidewalks and/or on-street parking.
The Federal Highway Administration touts roundabouts as being safer than four-way stops.
Roundabouts are touted as being safer because there are less points of conflict than with a four-way stop. Eight with roundabouts, compared to 32. There also are no right angles, meaning less of an impact if a crash were to occur.
According to the Department of Transportation, roundabouts have contributed to a 90 percent reduction in traffic fatalities, a 76 percent reduction in injuries and a 35 percent reduction in crashes. The DOT also says the roundabouts are safer for pedestrians.
