MARTA’s impending expansion

Moderated by Tom Sabulis

My column today deals with the ramifications of a “yes” vote to increase the sales tax in Clayton County by one penny to join MARTA. At a recent meeting, Clayton and MARTA leaders predicted a big majority in favor of MARTA on election day, and what that could mean for metro Atlanta. In our second column, a former director of the Governor’s Office of Highway Safety writes about the new varying speed limits on the north end of I-285, which some motorists are criticizing.

Commenting is open.

Will others follow Clayton?

By Tom Sabulis

You could have loaded the optimism on your Breeze Card when elected officials and transportation advocates spoke at a recent gathering about Clayton County’s upcoming MARTA referendum.

Four panelists — including Clayton County Chairman Jeffrey Turner and MARTA board chairman Robbie Ashe — agreed that Clayton voters will approve a one-cent sales tax increase on Nov. 4 in order to join the mass-transit system, thus marking the first expansion of MARTA outside Fulton and DeKalb in 40 years.

With that approval will come opportunity.

If voters say “yes” in convincing fashion – and both those leaders predicted voter assent will top 70 percent — Georgia’s rail future will be brighter than ever, not only in Clayton, but eventually down to Macon, and perhaps elsewhere in metro Atlanta -maybe even under the Gold Dome during the next legislative session.

“It’s crucial for regional transit that it pass and pass in a strong fashion,” Ashe said.

Other “jurisdictions” in metro Atlanta are closely watching the vote, he said. An indisputable “yes” vote could get them to think about joining the transit agency.

A resounding victory for MARTA may also turn state legislators’ heads.

“Everybody knows there will be a Plan B discussed in the 2015 general assembly,” Ashe said, referring to an alternative to the failed 2012 T-SPLOST referendum that was crushed in metro Atlanta.

“If we can pass a MARTA referendum with a strong majority then those folks will be more inclined to give transit generally, and MARTA specifically, a full seat at that table. That’s one of the other reasons why this matters so much.”

Clearly, there’s a lot riding on the vote. But MARTA advocates have good reason to be feeling good. The grassroots effort in Clayton is strong. County commission meetings this summer, during which the particulars of the ballot were debated, were packed with pro-transit residents. And a non-binding referendum on MARTA in Clayton a few years back showed strong support.

But even with a victory on election day, there’s a long way to go. The 800-pound gorilla in the room is Norfolk Southern, the railroad company that owns the tracks and right of way MARTA wants to use. Norfolk Southern would have to agree to work with MARTA in order for commuter rail to be the “high capacity option” that connects Clayton to Fulton and beyond.

If that doesn’t happen, MARTA will resort to its backup plan – Bus Rapid Transit (BRT) – something county chairman Turner says his constituents would like to avoid. “The citizens of Clayton County expect commuter rail,” he said. (Bus routes will serve residents within the county under either scenario.)

For his part, Ashe feels that negotiations with Norfolk Southern will work out. He explained his confidence regarding the railroad in business terms.

“We’re talking about making a couple hundred million dollar investment in their property,” he said. “We want to work out a relationship with them where we can use their right of way, either use their tracks or build a parallel set of tracks in their right of way next to it. We think the right of way is wide enough in most instances to be able to do that. We’d need to do some infrastructure upgrades to some of the bridges and things like that.”

Federal money is in play for commuter rail, too. The long-dormant $45 million in federal funds previously earmarked for commuter rail from Atlanta to Macon remains available. The Clayton sales tax increase would be the local revenue match that unlocks the money from Washington.

“We have the opportunity to do the first real commuter rail in Georgia,” Ashe said. “(The existing line) picks up the big population centers in Clayton County, aside from the airport, but it connects directly to the East Point (MARTA) station. We think we can have real commuter rail running five to seven years from now. That’s all contingent with us working out a deal with Norfolk Southern. That is not a foregone conclusion, but I’m cautiously optimistic.”

If commuter rail works in Clayton, advocates feel it could change the way mass transit is viewed in metro Atlanta and beyond. Others want to see how the Clayton vote shakes out.

With a big majority, MARTA could suddenly look appealing to other suburban counties choking on congestion – Gwinnett County, for example.

“I just look at the demographics in Gwinnett and I look at the need in Gwinnett.,” Ashe said. “This passenger rail conversation is a parallel that works really nicely between Clayton and Gwinnett….. given the amount of rail line running through Gwinnett County already.”

For the record, Gwinnett County Chairwoman Charlotte Nash said, in an e-mail Monday, said there are no plans to hold a MARTA referendum in Gwinnett.

Still, with MARTA service improving in general, with expansion likely in Clayton, and ongoing studies to expand north in Fulton, it will be interesting to see if the General Assembly throws any significant support to MARTA, or transit in general, in 2015.

Speed limit system needs time, patience

 By Bob Dallas

The times are a-‘changing, and so are the speed limits on the Perimeter (I-285). The Perimeter speed limits on the south side running below I-20 were raised to 65 mph several months ago. The Perimeter “Top End,” however — not so fast. There, the congestion, number of exits and safety concerns were significantly more impactful. While conditions on weekends and late nights supporting shifting the speed limit from 55 to 65 mph, peak hours suggested downshifting to a much lower speed.Before we protest too much, lowering the speed limit pre-peak is the most effective way to improve performance by averting the worst congestion during peak drive times.Why does this work? It avoids the accordion effect that creates stop-and-go traffic and significantly reduces the number of severe crashes that degrade the flow. Studies consistently show the optimal speed that accommodates the most vehicles is just under 45 mph.

Thus, drivers of the Perimeter Top End are now experiencing the new electronic signs that now display variable speed limits. Quoting the Texas A&M Transportation Institute: “Variable speed limits are enacted by signs that can be changed to alert drivers when traffic congestion is imminent. Sensors along the roadway detect when congestion or weather conditions exceed specified thresholds and automatically reduce the speed limit … to slow traffic and postpone the onset of congestion. The system’s goal is to slow traffic uniformly in a way that allows smooth traffic flow and avoids stop-and-go conditions.”

Variable speed limits also reduce crashes caused by multiple lane changes and quick stops.

What will not be intuitive to drivers is that the slowing down will occur prior to encountering congestion. Thus, a driver may perceive little congestion and question why the speed limit has been reduced.

As the goal is to prevent or delay the onset of congestion, slowing drivers down has to occur before congestion is experienced. This is the same concept applied to ramp meters stopping drivers before they enter the Perimeter, even when it doesn’t appear congested. By restricting the flow of vehicles entering the interstate, it flows more smoothly, and the impact on congestion is ameliorated.

In practice, speed limits will be lowered in several circumstances. First, a lane-blocking incident will trigger speed reduction miles before the incident. Second, adverse driving conditions, such as a pop-up shower or blinding sunshine slowdown, can be accommodated.

Third, and most impactful, is prior to predictable peak congestion, the speed limits will be lowered. For example, if the peak is at 7:30 a.m. when traffic cannot move at anywhere near the former 55 mph speed limit, anticipate the new 65 mph being incrementally lowered to 55 mph at 6 a.m., then to 45 mph or less at 6:30 a.m.

For drivers who believe speed limits are simply suggestions, or worse, anticipate more than one complaint over a citation issued for exceeding a lower speed limit when the road was “wide open.”

The concept is to slow down to get there faster. As counterintuitive as this is, it works.
