Mini-Roundabout Proposed for Busy Intersection

The Georgia Department Of Transportation is proposing a mini-roundabout to remedy one of Villa Rica’s more traffic-clogged areas.
GDOT has offered to upgrade the intersection of Dallas Highway and Punkintown Road on Villa Rica’s north side by the end of 2016. 
The concept will be proposed to the Villa Rica City Council at its June 30, 2016 meeting. If the Council agrees, GDOT has agreed to upgrade the intersection on its dime as a quick response project and install the mini-roundabout by yearend. GDOT modeling shows installation of a mini-roundabout should reduce delays by 68 percent for those traveling north on Dallas Highway (SR61) and 63 percent for those going south on Dallas Highway.
The intersection is currently governed by a three-way stop and right-hand turn lane on Punkintown Road. At the city manager’s urging, GDOT evaluated the intersection for traffic signals but found the intersection does not sustain minimum traffic counts to justify a traffic light.
GDOT policy requires consideration of roundabouts for existing intersections that have been identified as needing major safety or operational improvements. Mini-roundabouts have proven to be significantly safer than traffic signals and operate more efficiently than three-way stops. In fact, before and after studies by the National Cooperative Highway Research Program (NCHRP) of 55 intersections where roundabouts were installed throughout the United States found a:
35% overall decrease in crashes;
76% decrease in injury crashes
81% decrease in fatal/incapacitating crashes for single lane urban roundabouts; and a
71% decrease in fatal/incapacitating crashes for single lane rural roundabouts.
