Problem intersection in Dunwoody gets scrutiny

Tilly Mill Road at North Peachtree Road is congested, dangerous

Dunwoody is now focusing on how to improve one of the most problematic intersections in the city: Tilly Mill Road at North Peachtree Road.

Some of the safety statistics at the intersection should worry residents who frequently drive through it.

The accident rate on Tilly Mill Road is above the state average, according to traffic studies conducted by the city. About 65 percent of the total number of crashes at the intersection were rear-end accidents, which means that there is congestion and an insufficient length for vehicles to queue up before entering the intersection, according to traffic studies.

In addition, around 42 percent of the accidents at Peeler and North Peachtree roads were likely caused from vehicles entering the intersection from Peeler Road, which has no traffic signal.

The city’s comprehensive look at traffic problems in 2011 showed that the intersection is very congested, especially during rush hours.

City officials, at a regular board meeting last week, discussed problems at the intersection at length. The city public works staff is working on the preliminary design and could complete a design by 2012. Construction could begin next year, according to a city report.

While several options were studied for the intersection, the work is scheduled to include a traffic signal on Peeler Road before entering the intersection. Turn lanes would be added to lighten congestion near the intersection. Sidewalks and bike lanes would also be built, according to a city report.

Preliminary construction costs to improve the intersection are expected to cost $1.2 million.

The project goals are to make the intersection more safe, relieve traffic congestion, and open up the intersection for pedestrians and cyclists. City officials also want to beautify the intersection.

We do NOT need more traffic lights! Please city officials.... start placing more roundabouts instead of lights and stop signs. It's the congestion here that's the problem. Roundabouts on Tilly Mill at BOTH Peeler and N Peachtree would ease congestion a great deal and improve safety. Traffic needs to be made to FLOW not more stops.

As someone who lives on Peeler, I do not believe a traffic light is going to solve the issues here. However, if there is be a traffic light, I would only have it "operational" in the weekday mornings and evening during rush hour. It is not needed at other times of the day.

A simple roundabout is the answer! A roundabout could probably be done for a heck of a lot less than $1.2Mil. and the city wouldn't have to worry about maintaining the lights, etc. Grant a portion of the $1.2Mil to the Dunwoody Garden Club to maintain a flower bed in the island and you've solved the traffic problem and added a visually appealing focal point to Dunwoody. My 2 sense. ; )

Roundabouts were considered in 2 of the 4 options researched for the intersection. They were not chosen because they would require more land and that bumped the cost to over 3 million. They would work well, but the City would have to buy out 3 or 4 existing residences to make room for roundabouts. Contact your elected officials if you want this more expensive option reconsidered.

Roundabouts only work with considerate, law-abiding drivers. I regularly drive the newest one in Roswell and it is dangerous with people running thru the Yield sign on the required right turn.

Isn't the lot at the corner of N Peachtree and Tilly Mill Rd for sale? It's about $350k... Use the whole thing as the basis for the roundabout.

@mike - that may be your perception but statistics show that roundabout are more efficient and safer. There are fewer accidents and when there are accidents they are less serious due to lower approach speeds. I will admit some frustration at times with the Roswell roundabout at times but if you've driven that way as much as I have you'll know it's a vast improvement over the old 4-way stop. The more roundabouts we have the better drivers will be at using them. @Bill - Glad to hear they were considered. I wonder which types were looked at. There are definitely options with smaller footprints that would fit there.
