ASU Roundabout Study: More Crashes With 2-Lane Roundabouts

CARMEL, IN - A study out of Arizona State University is showing up more than 1,600 miles away in Carmel.

The study is based on the safety of roundabouts - those traffic circles at the center of a recent lawsuit between the City of Indianapolis and Carmel.

According to a report by RTV6, ASU's study found although single-lane roundabouts have decreased the number of accidents and injuries, two-lane roundabouts actually increase the number of crashes, though less severe.

In addition to those statistics, the number of those crashes are reportedly less severe, but the crash increase with two-lane roundabouts increased by more than 60 percent.

But where did that data come from? RTV6 reports an Arizona State Professor, Michael Mamlouk, took a look at data from several of Arizona's roundabout websites before and after they were completed, concluding the statistics come down to familiarity of using roundabouts.

To help increase your safety with the sometimes complicated traffic circles, RTV6 has provided an online list of tips and guidelines for traveling through roundabouts.

These guidelines can help improve travel when it comes to the safety debate of Carmel's dozens of roundabouts, and the ongoing lawsuit revolving around the 96th street roundabout construction bordering Carmel and Indianapolis.
