Problems with the subway signal system accounted for over 35 percent of controllable delays last year. (Photo by Benjamin Kabak)

Any veteran subway rider knows to dread an announcement concerning “an unavoidable delay.” Such a proclamation can precede an endless wait in a tunnel somewhere as some mysterious problem causes back-ups up and down the line. Details are scarce, and the waits infuriating. But what if those unavoidable delays aren’t so unavoidable after all?

For straphangers stuck in a train, the MTA delivers scant information. We never find out the why or wherefore of the service delay unless we seek it out. Yesterday, though, the Straphangers Campaign pulled back the curtain a bit, and after analyzing the 2011 service delays, what they found were a bunch of potentially avoidable delays based on the city’s aging subway signal system.

By analyzing the MTA’s text message alert system, the Straphangers produced a report on subway delays. The total world of delays included 4580 alerts, and the Straphangers determined that 1613 of them — or 35 percent of the total — were uncontrollable. That is, they involved sick passengers or police activity outside of the realm of the MTA. The remainder were indeed avoidable.

The remaining 2967 alerts encompassed delays due to signal or mechanical problems, and over 1000 of those were due to signal problems. The advocacy group offered up some topline summaries:

  • The 2 line had the most controllable significant incidents in 2011. The 2 line accounted for 251 out of 2,967, or 8% of all controllable significant incidents.
  • The 5 line came in a close second, with 247 controllable significant incidents. This was also 8% of all controllable significant incidents.
  • The G line had the fewest controllable significant incidents in 2011. The G line accounted for 45, or 2%, of all controllable significant incidents.
  • The most frequently occurring type of controllable significant incidents in 2011 was signal problems. This reason accounted for 36% of all controllable significant incidents.

The 2 and 5 lines, of course, share trackage in both Brooklyn and the Bronx so it’s no surprise that those two lines are intertwined in their delays. As critics of the G may say, since the train never runs, it can’t be delayed (but we know those numbers are due to the fact that it’s a one-train route from Queens until Bergen Street).

For its part, the MTA didn’t dispute these findings. “We agree with the Straphangers’ assessment that signal issues contribute to delays,” the authority said in a statement. “That is why signal upgrades remain a top priority and are a crucial part of our capital program. FASTRACK is also helping to improve how we maintain and improve our signals network.”

The Straphangers posed a few questions based on their data, and one in particular caught my eye. “Are there explanations,” they asked, “for why signal and mechanical problems constitute more than two-thirds of all significant controllable incidents?” The easy answer concerns the age of the subway infrastructure. Simply put, the equipment is very, very old; some signals are pushing 70. This technology needs to be better maintained and, more importantly, upgraded both to maintain current capacity and throughput and allow the MTA to expand its services.

A few weeks ago, I bemoaned the threat of a less ambitious capital plan. Joe Lhota had spoken then of looking at ways to spend less for a few years but invest in the hidden infrastructure. “It’s about signals,” he said. “If we’re going to have more throughput, we’re going to put more trains on the same track, and we’re going to have to have more modernized signals.”

So maybe this is indeed all about signals. The MTA plans to spend around $3 billion on signals over the next few years and will look to increase that amount when the pressures of funding — but not building — the megaprojects start to come off the books in 2015. Can we wait a few more years to upgrade this vital, if hidden, part of the subway system? We may have little choice, but all of a sudden, that less-than-ambitious capital plan looks a little more promising.

As Transit Wireless is hard at work bringing cell service to the New York City subway stations, the company has announced a deal to bring WiFi underground as well. Transit Wireless announced a deal today with Boingo that will see the company manage and operate a WiFi network within the city’s underground subway stations. The roll-out for the service will be gradual over the next five years and will cover stations in Manhattan, the Bronx, Brooklyn and Queens.

“Boingo has a proven expertise in operating easy-to-use wireless services in high-traffic venues serving people on-the-go,” Transit Wireless CEO William A. Bayne Jr. said in a statement. “Our partnership with Boingo helps us deliver on our commitment to providing best-in-class technology amenities to our community of commuters and visitors to the Big Apple.”

Boingo, known for its vast array of airport networks it operates, will be charging for the service. It’s roaming partners, which include Sprint, T-Mobile and Verizon may be able to use the service for a lesser charge as well. On the one hand, this is a positive development for New York City subway riders. On the other, it’s somewhat redundant as smart phone users will be able to use Transit Wireless’ own network to access the Internet. Still, this move should further the push toward technological innovation in the transit space.

I’ve grown up in a technologically oriented age. I’ve had a computer for as long as I can remember, the Internet throughout high school and Google for my collegial and professional careers. Still, throughout most of my first three decades, my native transit agency has had a tough relationship with technology. It’s begun to change, though, and over the next few years, we’ll see it progress even more so.

Until recently, the MTA’s embrace of technology was lukewarm at best. We had heard countless stories of the troubles. Bus tracking couldn’t happen in New York because of GPS interference in the canyons of Manhattan. One contractor had filed suit over a new monitoring project. Countdown clocks were perennially on the horizon. The website resembled something out of the late 1990s.

Lately, though, the agency has turned the page. We have countdown clocks in nearly every A Division station, new rolling stock that incorporates technological advances, a BusTime system slowly spreading across the city and a more dynamic website. No one will confuse the MTA with a groundbreaking technology company, but after refusing to release data for years, we’ll soon enjoy real-time subway arrival data. It’s a solid start.

Earlier this week, I attended a panel on technology in transit. Among the speakers at NYU’s Rudin Center were an app developer, officials from the Port Authority and MTA, a Google engineer and one of the leaders from Open Plans. They spoke at length about the role technology will play in the short- and long-term, and all five of the panelists agreed that the future will involve rapid innovation.

On an individual level, we know what to expect. The MTA will make its subway data available and will soon bring arrival boards in one form or another to its B Division. It’s also seeking to implement a next generation fare payment system. PATH is hoping to incorporate dynamic signage and a better train tracking system. Right now, for instance, Exchange Place-bound customers at the World Trade Center have no idea which train will leave first, and that’s a flaw that should be corrected.

Technological innovations that impact transportation aren’t limited to public transit either. The Port Authority is working on ways to bring more information about road conditions to the public, and it already pays off. When I have to drive around the city, I’ll always check the traffic conditions online before picking my route. In the future, we should have more information concerning delays and problem spots.

Of course, with the improvements — which cost money to implement and money to maintain — come questions. We’re living through an era of austerity. Governments refuse or cannot invest in transit service, and agencies have cut bus routes and train frequency. Meanwhile, technological innovations move forward, and many critics claim that flashy technology is simply a front of worse service. Should we accept countdown clocks if the trade-off is fewer and more crowded trains?

I asked the panelists to comment on that critique, and the answers were similar. We cannot move forward without technology. Many seemed to view the service cuts as somewhat temporary. When the money returns, so too will service. The technological improvements, meanwhile, can cost a fraction of what it would cost to restore the service cuts, and they serve to make commutes more convenient and passenger-friendly. The information helps riders plan their trips, and it can help the operations staff plan routes and frequency. The possibilities are endless.

I buy it. I embrace the technology. I crave the countdown clocks and BusTime, the Google Maps traffic layers and the simple signs pointing to the next train to depart. But I grew up enmeshed in technology. It is no replacement for frequent service, but we need the improvements to move forward. Now if only the MTA would release its Board committee materials in searchable PDF format. It is, after all, 2012.

A glimpse through the March MTA Board meeting materials revealed to the world a long-awaited development from the transit authority. The MTA had issued a procurement call for the technology to release a real-time data feed of available subway arrival information. The feed would cover the A Division lines that currently enjoy the benefits of countdown clocks and would open up a whole new world of transit data for app developers.

Earlier today, I spent the morning at an event at NYU’s Rudin Center for Transportation Policy & Management, and this upcoming data feed was a hot topic. The early a.m. event focused on technology and urban mobility. It featured panelists from the MTA and PATH and developers from Google Transit and OpenPlans (as well as Adam Ernst, a Second Ave. Sagas advertiser). Ernest Tollerson, the MTA’s Director of Environmental Sustainability & Compliance, opened the talk with a brief discussion on the real-time data feed.

According to Tollerson, the authority hopes to have the train arrival estimates ready to go later this year. At the time, app developers will be able to grab this information that covers 37 percent of all subway riders. It will be, he said, “a transformative moment in the life of the city and the MTA.”

Now, we’ve known about the looming public release of this data for a few weeks, but Tollerson let slip some additional info as well. After the real-time data streams are live, the authority will look for ways to push out real-time information for B Division lines that are elevated or at-grade. In other words, most lines out in Brooklyn and Queens would be in line to receive these feeds as well.

Tollerson and the rest of the panelists spoke about the ways in which transit technology can make trips more convenient. If we know what’s happening where and when before we leave our house, we are better prepared for delays or the need to find alternate routes. Making the voluminous train location data available to the public is a huge step for the MTA and for the millions of people who ride the subways every day. That moment cannot come soon enough.

If all goes according to plan, the MTA will soon offer real time train information from the countdown clocks to app developers. (Photo by Kim Last)

As the MTA has expanded the widely popular countdown clocks throughout the A Division stations, a common cry has concerned the lack of publicly-available real-time data. As I mentioned during my talk at the Transit Museum last month, Transit is sitting on a wealth of data that could redefine how we ride and wait for trains if only they would make the feeds from the countdown clocks available in real time.

A tidbit in this month’s MTA Board book reveals that the authority may read to release the data. According to the procurement summary, Acquia, Inc. has bid $771,758 on a contract to install cloud-based infrastructure and a web application that will allow the MTA to offer a real-time feed of train location data to the public.

“The MTA can build on that success” of the countdown clocks, the Board materials read, “and expand our customer’s access to real-time data exponentially if the MTA creates a web feed for application software developers. Creation of an MTA web feed of subway arrival estimates for A Division lines 1 through 6 will make it possible for app developers to deliver real-time information currently displayed in countdown clocks to our customers’ cell phones, smartphones and other hand-held digital devices.”

Such a feed would be a welcome addition to the transit app landscape and would allow straphangers to eliminate the element of surprise from many of their off-peak subway trips. According to the MTA documents, 37 percent of the daily ridership would gain access to any apps that incorporate real-time subway data, and in the future, the MTA would provide real-time subway arrival estimates from B Division routes as well.

To get this effort off the ground, the MTA will leverage an existing New York State Senate contract with Acquia to use cloud computing and Drupal as a content management and development frameworks. The authority aims to spend just over $521,000 with a contingency of $250,000 included in the bid. It is worth the cost.

“A launch of a web feed for lines 1 through 6 would significantly improve customer service and being to deliver the same level of customer service available to those who use mass transit in other major U.S. and world cities, including London, Chicago, Boston, San Francisco and Washington,” the staff summary said. I’m looking forward to it.

At a few stations in Manhattan, Brooklyn and Queens, the MTA has installed touch-screen information centers that serve as a clearinghouse for transit information and neighborhood direction. These “On-The-Go” stands are part of a pilot, and now, according to The Daily News, the MTA wants to bring these terminals everywhere. If all goes right, 468 subway stations may be equipped with these information kiosks.

Pete Donohue has the skinny on the authority’s plans:

The MTA wants to install 47-inch interactive tablets throughout the entire 468-station subway system, the Daily News has learned. The Metropolitan Transportation Authority envisions posting the “virtual agent” near turnstile banks “where the station booth or phone bank has been removed or (in) other areas of unused space,” according to an agency document.

The digital On the Go! screens would also be placed on platforms, replacing standalone paper maps and weekly service diversion notices that workers now change by hand. Going digital will allow officials to update information and advertising remotely, officials said. The ads could even be tailored to specific times and neighborhoods.

…The MTA doesn’t yet have a rollout schedule or project cost, [Transit spokesman Charles] Seaton said. It’s soliciting information from private firms on how to move forward, he said. One possibility is having a corporate sponsor pick up the tab in exchange for having its logo on every kiosk or a share in the advertising receipts. The screens are not part of any plan to further reduce station staffing, the authority said.

That last item will, of course, placate the folks who have long protested the decline of the station agent. In a way, though, it’s a false promise as the station agents are gone and not coming back. Still, the digital screens could be more helpful in certain ways. They can be connected to a network that allows the MTA to update the boards with real-time train alerts and can provide more information about the surrounding neighborhoods than many station agents could.

The real question though concerns vandalism: Can these screens withstand the subway environment and all that comes with it? The pilot devices are built to take a beating, and the other 465 others would have to be as well. Meanwhile, the MTA would also have to deal with inevitable upgrades. A typical computer is out of date after a year and ready for replacement in three of four. These items too may need to be on a replacement cycle or else the technology will grow stale as the Metrocard Vending Machine has. In any event, more information and a better delivery system should only improve commutes.

Since the early fall, my commute has involved only IRT trains, and as I’ve written in the past, I find the countdown clocks to make waiting for the next subway a far less stressful experience. As all of my stations now have these clocks, I’ve also started focusing on what the wait times can tell us about subway headways, and I’ve often taken to Twitter to post my observations about train bunching. It seems to happen far more often than we would like.

Take, for instance, off-peak patterns on the 2 and 3. Oftentimes, I’ll see a long wait for a downtown 2 train and a much shorter wait for the 3 train right behind it. The wait times may average out to acceptable headways, but the reality of the situation is far more subtle. I witnessed another strange happening this past Saturday when three downtown 1 trains past within 5 minutes of each other at around 5:15 p.m. Accordingly to the MTA’s schedule, those trains should have been operating with eight minutes of headway rather than 100 seconds.

Some of this bunching may be unavoidable. Perhaps an earlier delay on the 1 line caused Saturday’s bunching, but the 2/3 bunching happens often enough that I wonder if it’s a scheduling issue. The 3 makes just one stop after leaving its terminal before joining up with the downtown 2 that the dispatcher should be able to avoid such bunching. I’ve noticed, however, that the late-night schedule features Manhattan-bound 2 and 4 trains running with similarly mistimed gaps in Brooklyn.

One day, I hope the MTA releases the wealth of data currently being collected by the underlying technology supporting the PA/CIS system. It would provide a glimpse of how trains are running with what spacing as they make their journeys to their ultimate destinations. Perhaps we’d see bunching, and perhaps too we would be able to isolate why bunching happens by discovering which trains are experience high dwell times. For now, though, we just suffer through mystifying and frustrated bunching as the countdown clocks tick down the minutes until the next two trains arrive.

Explore the Transit Museum before my discussion with Sarah Kaufman next Wednesday. (Photo via the New York City Transit Museum)

I have some exciting news for you subway buffs and transit policy wonks out there. I’ll be hosting a Q-and-A series at the Transit Museum this year, and the first event kicks off the series on Wednesday, February 1 at 6:30 p.m. Save the date.

The series is entitled “Problem Solvers,” and it will take an intimate look at the people who are working behind the scenes to change the face of our transit system as the subway approaches its 110th birthday. My first guest will be Sarah Kaufman, currently with NYU Wagner’s Rudin Center for Transportation Policy and Management and formerly the MTA’s open-data guru.

While with the MTA, Kaufman created a conference and online exchange between the MTA and software developers and assisted in developing the agency’s social media program. She specializes in the use of cutting-edge technologies in transportation, particularly mass transit, and the opportunities for community involvement in transportation management through interactive technologies.

Sarah and I will talk for a bit about her work and the problems she’s trying to solve before we open the floor to audience questions. The program kicks off at 6:30 p.m., and doors to the museum will open at 6. Guests are invited to walk through the museum and to explore the collection of old trains at the former Court St. station. Light refreshments will be available as well. I’ll host another session on April 25th with another member of the transit community.

More details after the jump. Hopefully, I’ll see you there.

Video: Introducing SI BusTime

Posted by: | Comments (5)

Real-time bus tracking made its Staten Island debut on Wednesday, and this week, the MTA released video exploring the technology. Give a watch to find out how the authority, working with students from Columbia and the folks from OpenPlans, have improved upon GPS-based technologies. I’ll have more in the coming weeks on how the agency plans to tackle the canyons of Manhattan and how you can track buses as they move through the Brooklyn Battery Tunnel.

As I’ve mentioned before, I’m one of the judges in the ongoing MTA AppQuest contest, and today, the MTA and ChallengePost released a video urging the public to vote for their favorite apps. In a few weeks, my colleagues and I were determine our winner, but for the next 23 days, the public can vote for their favorite. Right now, it appears as though the NYC Station Finder is in the lead, but take a glance through the submissions gallery and pick your favorite today. The winner of the popular vote will get a $2000 prize, and the public will get a whole new slate of transit apps to help augment our rides.
