MARTA, streetcar wait times

Moderated by Tom Sabulis

Last week, I wrote about my frustration with long wait times on MARTA and talked with agency officials who explained the cost of adding more service. Today, I visit with a Georgia Tech engineering professor who is trying to cut down on the inconvenience of waiting by introducing technology that will keep riders informed on how long it will take before their bus or train reaches their stop or station. In our second column, a transit consultant comments on the Atlanta streetcar system’s projected wait times.

Commenting is open below.

Aiding transit in real time

By Tom Sabulis

Given metro Atlanta’s transportation mess, it’s refreshing to find progressive thinkers who are looking to improve things within the existing infrastructure, at little cost to anyone.

Kari Watkins is an engineering professor at Georgia Tech who, while at the University of Washington, co-developed a computer application for Seattle transit called OneBusAway. The app taps into vehicles’ GPS and provides real-time arrival information on users’ computers and mobile phones. This allows riders to limit their wait times at bus stops and train stations.

Watkins and her Tech students are now working with MARTA to develop similar technology here. (The coding for OneBusAway was also used to create MTA Bus Time in New York.)

In Seattle, project research for OneBusAway, available at, turned up some interesting findings:

• Surveys show that people perceive they are waiting much longer for transit than they actually are — some research suggests up to twice as long — but Watkins found that with real-time information, there is no longer a difference between perception and reality.

• Eleven minutes’ wait is the cutoff point at which people will begin to consult transit schedules instead of showing up randomly at stations. (MARTA trains run about 15 minutes apart; bus waits can be 30 to 40 minutes or more.)

When OneBusAway started in Seattle, there was a 30-percent increase in the number of trips people said they took as a result of having the information. Women, especially, said they felt safer knowing when the bus would arrive so they could wait in more secure surroundings if they wanted to.

OneBusAway has more than 100,000 unique weekly users. Many say it gives them a sense of control over their trips and commutes.

A Tech alum, Watkins began pressuring MARTA to open up its schedule data when she arrived back in Atlanta almost two years ago — “so computer programmers could grab the data and … write applications that will help you as the rider.” Once MARTA agreed, Watkins began developing a version of OneBusAway for Atlanta. It’s now being tested internally.

“Our goal is to do a wider deployment in June,” she said. “Ideally, we wouldn’t open it up until we had rail service in it, because I don’t think we’re going to get a big audience in Atlanta from bus only.” (Seattle, in contrast, has robust bus service, as well as light rail.)

“The ultimate goal,” Watkins said, “is to open it up when we have both bus and rail,” and then slowly add university and Atlantic Station shuttles and other transit systems such as Cobb Community Transit. “Basically, anyone who has the information, we can add it so it’s in the same program.”

Yes, MARTA already has real-time message boards that tell you when trains will arrive. But they’re of limited help because you must enter the station and go to the platform to get that information.

“The beauty of mobile,” Watkins said, “is you’re not actually going to the transit stop first. If you have the information on your device, we can be sitting here talking, and I can click a couple buttons and say, ‘Oh, my bus isn’t coming for 20 minutes, let’s take our time.’ You can imagine apps in the future that will beep at you, ‘The bus is five blocks away.’”

Because OneBusAway utilizes open-source software, users can submit improvements of their own and develop complementary apps and websites. In Boston, somebody created a countdown sign for a coffeeshop near one station.

Watkins lives in Virginia-Highland with her husband and children. Most days, she commutes to Tech on her bicycle. She takes the bus occasionally, but finds the wait times too long for her busy schedule. Still, she is no MARTA critic. “I understand the frustrations, but I actually get mad at the people who get mad at MARTA, because they do a great job considering the resources they’re given. They are so cash-strapped.”

Watkins said she has made no money off OneBusAway in Seattle, nor does she plan to in Atlanta. “That’s not the goal. The entire goal is to bring about change — to make it easier to use transit so that we can have a more efficient transportation system. It’s kind of a grassroots effort.”

There are many challenges in getting more people to use MARTA. In helping those who already use the system, OneBusAway in Atlanta could stem dwindling ridership numbers.

Will the streetcar be useful?

By Jarrett Walker

When a new public transit technology comes to a city, it’s a chance for everyone to think again about transit. People who think they’d never ride transit often give the new technology a try. Sometimes, the results can change the city for the better, and create new possibilities for transit all over the city.

All those hopes cling to the new Atlanta Streetcar. As in other cities that have built modern streetcars including my hometown of Portland, Ore., the hope is that the pleasant experience of riding the streetcar will make people value transit as a whole, as well as making downtown a more attractive place to live, shop, work and play.

The modern streetcar movement, which began with Portland’s streetcar in 2000, has always been about the emotions that streetcars generate. They’re as sleek as an airplane, yet they remind us of the vast streetcar networks that existed a century ago. The emotional genius of streetcars, then, is that they’re futuristic and nostalgic at the same time, and that’s enough to charm almost anyone. A tech-obsessed teenager can ride with his grandmother who recalls the streetcars of old, and both will feel their heartstrings pulled.

But streetcars present a risk: With all that excitement on the part of everyone involved, it’s easy to forget that transit must also be useful.

The Atlanta Streetcar line will be only 1.3 miles long from end to end, and a streetcar will come every 15 minutes if everything’s on time. So if you just missed one, should you really wait? Or should you just start walking?

It depends on your walking speed, but for most people, when going such a short distance, service every 15 minutes is just not worth waiting for. Start walking! You will often get to your destination before the streetcar comes.

As you walk, maybe the streetcar will overtake you and you can hop on. That’s nice, but notice what you’ve just proven. If you’re going to use the streetcar to get somewhere on time – a job, a meeting, a day care pickup – you have to allow enough time to walk the whole way. In that case, what has the streetcar accomplished?

It’s fun, it’s sleek, it will be helpful to those who can’t or don’t want to walk. But is it useful?

If you usually get around by car, it’s easy to miss this point. In transit, frequency is freedom. Motorists (and cyclists) have a vehicle that’s ready to go when they are. Only when transit competes with that convenience — with a vehicle that’s always coming soon — does it begin to be relevant to the lives of people who value their time, and thus to the life of the city.

Shamehia @ 11:34 am = FYI, that was the train designed for the Bankjead station Route, returning to Five points most likely. Most frequent riders are aware of its use and purpose.

I attended an event @ the GA Dome on Saturday that, at the conclusion, put a very large crowd of people onto the platform of the Dome/GWCC rail station at one time. The little eastbound train that eventually showed up was the shortest MARTA train I have ever seen – it was like four cars. Those of us who managed to board were packed in like sardines. What on earth is MARTA thinking? It’s like they’re brain dead.

1.3 MILES at what COST – - – $96,000,000 and counting. WHAT IN THE HECK have our politicians done now????? A streetcar to one of the most crime ridden areas of Atlanta. WOW – is anyone going to ride this thing at high noon much less after dark.

THIS PROJECT NEEDS TO BE SEVERED FROM THE FULTON COUNTY TAXPAYERS NOW!!!! I am tired of my hard erned money being wasted time & again by the idiots who run ATLANTA & FULTON COUNTY. I already have to pay for MARTA & GRADY – enough said!

By the way – WHO IS GOING TO RUN & MANAGE the STREETCARS??? Does anyone know

Will the streetcar be useful? Slightly. Mostly for tourists.

Streetcars in general? Yes. But, here, they need to connect the area west of the connector (Coke, Tech, Atlantic Station) with the MARTA rail line.

Real time transit info in an app? Yes! Particularly if it’ll tell me if my GRTA bus is on time. Gotta plan that afternoon nap, you know!

While clearly nobody who will be forced to pay for this boondoggle supports it, you can better believe that the parasites receiving all of the money for the sale and operation are loving every bit of it. And you thought city and state government represented the people….suckers.

Wow, a streetcar line that is 1.3 miles long and will only come every 15 minutes! If there is only one streetcar on the line, that means 7.5 minutes of travel time each way or an average speed of about 10 miles per hour. If there are two streetcars on the line, equally spaced, that means the street cars will be averaging 5 miles per hour. If you travel the whole strretcar distance you save at most about ten minutes. You might as well save the fare and get some exercise. How lazy or rushed are we? This won’t help businesses either, who before had people walk by their door and maybe stop in, who will now ride by without stopping.
