You'd be kicked out of any serious meeting of engineers or any mobility study.

Effed up interchanges and backed up clpouds of exhaust fumes does not inhibit or encourage more people to drive!

You're supposed to make the best of what you have not leave dangerous conditions trying to discourage travel by car

I'll bet you know nothing about this area or even use public transit daily.

As wonderful as transit and cycling are, we need to help the people who need to drive their cars: who need to drop off their kids, who are old, sick, running errands, carrying the tools of their trade, those who don't want to be a rained-on or sweaty mess when they get to work, who are delivering goods, who are nurses on the nightshift. . .those of us who are trying to go from 85N to right on Clairmont every morning of every weekday, those people.
Hear, hear!

People get way too hung up talking about commuter traffic. That's just a small sliver (about 20%) of the people on the road. The vast majority of drivers are shopping, going to the doctor, picking up kids, visiting friends, transporting goods and services, and a million other things.

Oh, I know. Moore's Mill westbound in the afternoon backs up for half a mile or more at Wesley, even though 90% of the cars are going straight through the light. One left-turner stops the entire road for the whole light cycle.



So, 10-15 years ago?



This I can agree with. Although, I have thought about and wished for Bolton Road to get a bridge over Marietta Blvd. It's a huge bottleneck for the area, with backups on Bolton/Moore's Mill and on Marietta Blvd. stretching some 3/4 of a mile most afternoons. It's an area with no feasible alternative route around.



You don't really need extra capacity sometimes. Just better design. Sometimes, that just means reconfiguring intersections to handle the flow. For instance, a longer right turn lane or the addition of a left turn lane could work wonders in many areas. Getting rid of red left turn arrows at some intersections where visibility is not a problem would help greatly. Hell, just retiming lights at some intersections where signal phases can last 3.5 minutes for one major road, and less than a minute for the intersecting major road, or where the signal phases prefer the small road over the major road.



Most of those roads are nowhere near capacity. Juniper, West Peachtree, and Spring are nowhere close to operating at capacity, so a road diet doesn't make much of a difference. Around PCM, going from a narrow-lanes six-lane road with no turn lanes to a wider-laned four lane road with turn lanes will operate much better. But, what do you think it would be like if Moreland went down to one lane each way? Not pretty.
They already did that at Ponce in order to put in a left turn lane. Definitely backed up Briarcliff/Moreland more than before.

I was referring to both North and Ponce as having already been done. The last bit eastbound leading up to Briarcliff/Moreland has not changed in at least 12 years. It's always had a left turn lane.

Fact: Roads / interchanges at capacity cannot bring in more traffic to the area than they already are, unless you expand them.

Fact: People will avoid areas with heavy traffic for a faster route or other alternatives.

Fact: Roads / cars alone are simply too low capacity to handle all the movement of people in a city with a population as large as Atlanta.

If roads in an area are reaching capacity, the focus should be increasing higher capacity alternatives.

If we want to talk about some incremental changes to this area to slow traffic and improve safety that makes sense. But things like making Briarcliff @ Clairmont an overpass will not make it past the first public meeting even if you find a source to fund it. Heck, Briarcliff is a two-laned road with homes on it on both directions from Clairmont. I had a childhood friend who's house was right on Briaircliff.

Well, lets just say we did put transit through there. I personally am not opposed to it, however; it is sounding like it will need to share ROW with existing traffic which is a clusterjam - how will a transit / bus / BRT even do any better if the infrastructure cannot accommodate for literally any more additional vehicles (which includes the buses)?

Fact, you can increase throughput of an intersection without widening the road.

Yup. Like through neighborhoods.

We should also be looking at ways to make the roads not bottleneck at certain spots, and instead improve flow at those spots.

If traffic is jammed up, what exactly are you going to do to slow it down??

I think the planned ART is a fine incidental next step.

Keep the area mostly as-is for now (besides possibly some minor safety improvements), and add ART so people start to have even a basic reliable transit option. Once the area further develops we can look at things like getting dedicated right of way / BRT / LRT, but you are probably looking at at least a decade or so before it needs that much added people capacity there.

Edit: Most of the delays are just for a few hours a day. Reworking the intersection so the buses get to bypass the queue and get their own priority light are the solution if the delays end up being more than 5 or 10 minutes getting through that area at peak times. But that could still come after the initial ART implementation. It also could be a good phased approach towards a long term plan of BRT operating in that corridor.

Correct. Which would also bring additional traffic to the area. No thank you.

Improvements should be limited to safety only (and only incremental in scale).
