In the wake of the failed transportation tax, Gov. Nathan Deal has declared the door slammed shut on rail expansion. Georgia’s likely future seems to be for roads, roads and more kinds of roads. A think tanker below talks up tolling arterials such as Roswell Road. The Sierra Club, which helped defeat the T-SPLOST and its rail component, doesn’t believe this is a good idea.
Commenting is open below Mark Woodall’s column.

When transportation experts compare Atlanta’s congestion problem with that of comparable large urban areas, one major difference leaps out of the data. Atlanta relies far more on its expressways to handle rush-hour traffic than comparable areas.
In Orlando, major roadways called “arterials” handle more traffic than expressways, and Denver’s arterials handle nearly as much as its expressways.
By contrast, Atlanta’s arterials handle only one-fourth as much traffic as its expressways. That’s a major reason why Atlanta’s expressways are among the nation’s most overloaded.
It’s probably way too late to build a modern grid of major arterials in Atlanta, but if some way could be found to make existing arterials like Roswell Road work better, those roads could reduce the burden placed on expressways, easing everyone’s daily commute.
The most obvious way to improve arterials is to widen them, but that is costly and can be politically contentious if landowners don’t wish to sell the needed right of way.
Another good idea is to synchronize traffic lights, so that motorists in the peak direction at rush hour get mostly green lights. Traffic engineers know that delays at intersections can be as big a limit on an arterial’s traffic capacity as the number of lanes.
What if it were possible to increase an arterial’s traffic capacity by more than would happen by adding a lane each way — but without having to widen it? Miami and Fort Myers, Fla., are both looking into this idea. It’s called converting an arterial into a “managed arterial.”
The basic idea is to give motorists a way to bypass traffic signals, by adding overpasses or underpasses to major arterials. Because those “grade separations” are costly to build, a small toll (e.g., 25 cents) would be charged, electronically, for each underpass a motorist used.
Those who didn’t want to pay would use the intersection just as they do today — to go straight or make a left turn or right turn.
It’s the same principle used around the country for express toll lanes on expressways, like the ones now working well on I-85 in Atlanta. You pay only the toll, using Peach Pass, if the value of the faster and more reliable trip is worth it to you.
Could the improvements that convert a regular arterial into a managed arterial pay for themselves? Preliminary studies in Florida cases suggest that as much as 75 percent of the cost of adding a set of overpasses or underpasses could be financed by the toll revenues, leaving the balance to come from conventional transportation revenues (mostly gas taxes).
By contrast, if the alternative of adding lanes each way were pursued, 100 percent of the cost would have to come from gas taxes.
Managed arterials offer metro Atlanta a way to relieve the area’s overburdened expressways, funded largely by voluntary payments by motorists. It’s an option transportation planners should seriously consider.

Fresh off the disastrous rollout of “managed lanes” on I-85, the highway lobby is back with its latest innovation for Atlanta — “managed arterials,” the idea of transforming our familiar surface streets into a grid of junior expressways, allowing cars to zip along where now they must wait for lights at intersections.
This transformation would be accomplished by converting existing intersections into “grade-separated” facilities, with underpasses and overpasses that are to be built and maintained by electronic tolls on the drivers who use them. Similar to the I-85 managed lanes, two classes of drivers will result: those willing and able to pay a toll to bypass the intersection, and everyone else, who will sit in traffic on the “unmanaged” lanes that may in fact be worse than it was before.
Lost in this discussion is the fact that these intersections would become stark, industrialized environments once the projects are complete. Residential and commercial properties that have existed for decades could see their access severely curtailed. Pedestrian and bicycle accessibility, already poor on many of these corridors, will become even worse. The only redevelopment options will be intensely automobile-oriented uses, resulting in even more car trips — a perfect example of induced demand. How is this going to reduce congestion?
Time and again, Atlanta has fallen victim to the simplistic notion that the solution to traffic congestion is to build new roadway capacity. Many of our most congested roadways — Interstate 285, for instance, or the current 14-lane incarnation of the Downtown Connector — were originally pitched as “congestion-relief” projects. Such an approach provides short-term relief at best. Eventually, it only serves to perpetuate a development pattern that depends on cars, which quickly overwhelm the new capacity.
It is time for Atlanta to move beyond the idea that traffic congestion is a problem that must be “solved.” Yes, traffic is bad in Atlanta, but so is it in any economically vibrant region where people want to be. In fact, Atlanta doesn’t even rank in the top 10 most-congested metropolitan areas in the country. Traffic in many of the cities we worry about competing with is even worse.
So what are other successful places doing that we aren’t? The answer is not building “managed arterials.” Instead, they are building the multimodal transportation systems the 21st century requires. They are investing in proven options such as commuter and intercity rail. They are addressing issues of regional transportation governance and are creating efficient, integrated systems. They are making the most of their existing transit infrastructure. In other words, things Atlanta has been failing to do.
Make no mistake — Atlanta still has great potential. But we must stop repeating the mistakes of the past and look toward the future and the transportation system we want — one in which residents have choices and one that attracts the businesses and job seekers of today.

“Managed arterials”, I saw that my first thought was it’s some new nutritional health idea from Mayor Bloomberg.
{{”Seriously, before we invest in expensive new congestion control fads there are low tech basics that need to be implemented that don’t require a T-SPLAT.

I agree that such low-tech basics as roundabouts at crowded lower and moderate-volume intersections and traffic light synchronization can help traffic flow on surface streets and roads tremendously.
But one of the major problems with our road network is that it is effectively totally and completely built-out in most spots, meaning that most roads cannot either physically or politically be widened any further because of existing heavy commercial and residential development and popular greenspace and thick tree buffers that line both sides of many major arterial roads and freeways.
Roads and freeways can only be expanded so much before it either becomes cost-prohibitive and too politically-contentious or even downright politically-impossible in many cases to do so, which is a point that the Atlanta Region seems to have reached in the aftermath of the defeat of the wildly-unpopular T-SPLOST.

I didn’t see your design submission for this interchange that handles about 4-500,000 cars a day! And you have an engineering degree from where?And how do you plan to pay for your Northern Arc?

This is probably the first time in my life I’ve actually agreed with the Sierra Club… Yikes!
This notion that you can “fix” traffic congestion is folly. Some of the worst congestion is on the roads we’ve spent the most on expanding capacity over the years.
The notion that you can build transit to “fit” travel patterns developed around roads is folly, too, obviously.
But, the region isn’t static. It is growing – or at least there is a desire for it to grow.
What you build determines how growth occurs. Manhattan didn’t become what it is by building all those skyscrapers and then asking “how are we going to move all those people?” Manhattan and transit grew up together. Building transit is not now and never has been about conversion of existing trips. It’s always been about growth.
If you build roads, you will get more highway oriented development. If you build transit, you will get transit oriented development. This SHOULD be obvious to everyone….
Trips by auto are, and will remain, the primary means of travel from just about every industrialized nation. This does not preclude smart development of transit – they are not mutually exclusive propositions. Neither is always “better” than the other.
Transit will pretty much always require an operating subsidy. This is the red herring that is often tossed into the fray. But the operating subsidy SHOULD BE a trade-off against savings in capital cost for developing the capacity. For example, if you need to move 10,000 commuters an hour, that’s a 10 lane freeway vs. a two track transit line. The highway is going to cost multiples of what the freeway costs to build and will more than offset the ongoing operating cost of the transit line.

NetBanker,
I agree that we should provide alternatives for those with longer commutes. However, we are reminded daily that the majority of those living OTP are of the “NIMBY” type when it comes to transit. They fear it will bring crime and unfavorable ppl to their precious cookie cutter neighborhoods. We can’t force them to accept transit as a viable transportation solution, so maybe the “core” should refocus and build up it’s transit network (which the ATL Metro TSPLOST vote map showed the core willing to invest in) to ease intown congestion and help bring transit to the modern era here in ATL. In time, with the help of rising gas prices, the outer region will hopefully realize there isn’t any other option but to extend lines out.

Seriously, before we invest in expensive new congestion control fads there are low tech basics that need to be implemented that don’t require a T-SPLAT. Synchronize the traffic lights (which Mr. Poole mentions), build roundabouts, widen and keep widening roads until they’re adequate to handle the traffic, extend turn lanes until they’re long enough to accommodate everyone making a lefthand turn, repaint lane and gore lines, upgrade signage, repair potholes (hello DeKalb County), enforce speeding, tailgaiting and pedestrian jaywalking laws. Not rocket science stuff, but the people we pay to manage traffic need to stop bellyaching and just do their jobs.

The answer to generating funds for transportation improvements has to lie in a toll for using interstate highways.

“introduce tolls for those SOV drivers coming from OTP into the city to help influence ppl’s transportation decisions. Carpools of 3+, vanpools, express bus, etc. would be waived of the toll.” This approach has been successful in London by charging a significant toll to drive into the city center for everyone excepts residents. Traffic was reduced and flows much more freely. That solution only worked because London has excellent rail and subway service as alternatives. I don’t think the solution of getting city drivers off the road to free up space for those coming from outside into the city makes sense…provide alternatives for the longer commuters that allow them to get out of their cars as well. Having ridden a train to work from burbs to city for 7 years I LOVED it. I could read, work, nap, text, whatever without having to deal with idiot drivers or worrying about if the weather is going to impact my commute.

“libertarians are such strong defenders of sprawling development styles and the so-called “freedom” to live anywhere you want regardless of where your job is located….you should accept the consequences of a long commute if your housing decision brings one upon you. ”
Patrick…I understand the sentiment, but jobs move frequently so taking an approach of deal with the consequences of where you choose to live in is a convenient statement that doesn’t actually solve any problems related to traffic and is entirely impractical on a personal level. In my 17 years in the Atlanta Metro area I have moved my residence 3 times spending 14 of those years in a house in suburbia. During those same 17 years my work locations have moved 9 times between 2 employers. Bank of America moved my office 5 times based on job assignment at the bank and my company has gone through 4 acquisitions resulting in 3 office moves (each further and further north of the city). Based on your logic I should sell my home and move closer to the office each time the office moved farther from me. In at least 4 cases the office moved to an area you would not chose to live in if you have any concern for crime statistics, property values, and school systems.
Transit isn’t just about a daily commute to work. It includes getting to events like ball games, concerts, and enabling visitors to move about the city to take advantage of what is available (it also means you wouldn’t have to cart your visitors around the city and pay for parking, tolls, etc). Heck…even if all we did was improve air quality so kids can actually play outside without having to check the Air Quality Index alert every day in summer by instituting transit it’s a win for everyone and reduces healthcare expenses.

“Managed Arterials” would be one of the worst ideas ever for this city and would only cause this city to be choked out more by the personal automobile while introducing a new form of urban blight. Options are needed inside the perimeter that don’t revolve around a single occupancy vehicle. Getting ppl to use alternatives inside the perimeter would free up congestion for those coming from outside the perimeter. In addition, introduce tolls for those SOV drivers coming from OTP into the city to help influence ppl’s transportation decisions. Carpools of 3+, vanpools, express bus, etc. would be waived of the toll.
Pouring more concrete will never relieve congestion… true change in the majority’s behavior will.
