Roundabout Open House: A public meeting regarding proposed roundabouts was held on Thursday, March 21 from 5:15 p.m. to 9 p.m. at Clark Middle School, 4600 Colby Drive. The open house was a 'come and go' format, allowing residents to speak with city traffic engineers and consultants.

| Traffic Control |
Traffic in the circle yields to entering traffic. As traffic volumes increase, traffic circles would lock up and would require the addition of stop signs and/or traffic signals to function. |
Traffic entering the roundabout must yield to traffic already traveling on the circular roadway. In a multilane roundabout, you do not change lanes. |
| Size |
Typically 300 feet or more in diameter. |
Roundabouts are typically 90 to 180 feet in diameter. |
| Speed |
Since traffic circles are larger, they are usually accompanied by higher speeds and lane changing issues |
Roundabouts are designed to keep speeds around 20mph to 25mph. This increases safety so when a crash does occur, it is a low speed crash typically resulting in property damage only |
| Safety |
Traffic circles have high-speed right angle (t-bone) crashes just like a traditional intersection. |
Roundabouts by design have vehicles enter the circular roadway at an angle. This angled entry combined with the use of channelizing islands slows vehicles and reduces the number of conflict points. This results in the elimination of high-speed right angle (t-bone) crashes, and when crashes do occur, they are typically low speed property damage only crashes. |
