Metro Relaunching System to Provide Data on Next Bus's Arrival Time

Metro is relaunching a long-awaited real-time bus arrival system that is supposed to tell riders when the next Metrobus will arrive at their stop. The system could make the area's largest regional bus service a more viable option for thousands of people who now shun it because of its unreliability.

Starting July 1, Metrobus customers should be able to find out approximately when the next bus will pull up to any one of about 12,000 bus stops across the Washington region. Riders can get the information by phone, online or via electronic signs at several high-volume bus terminals, including the Pentagon, Anacostia and Friendship Heights Metrorail stations.

Political pressure to improve bus reliability led Metro to run a pilot almost two years ago, before the system was ready. The test, on 32 routes, was suspended because of internal communication and dispatch problems that made the system only 80 percent accurate. Even so, riders on those routes said the information was a huge improvement over printed schedules, which they say bear no resemblance to reality.

NextBus technology will cover all 355 Metrobus routes and all of the more than 1,500 buses in the fleet. The goal is 90 percent accuracy.

Transit advocates said the real-time information could transform the bus-riding experience.

Many regular Metrorail riders, who can usually rely on electronic platform displays that show when the next three trains are arriving at a station, don't take the bus because there is no way to predict when it will arrive.

"This is a really big deal," Metro Board member Chris Zimmerman said. "This will give people some idea of whether it pays to wait for the bus and, if so, for how long. Time management is one of the key facts of our lives, and in the Washington area, the transportation schedule is one of the biggest challenges for most people."

As traffic worsens and Metrorail nears capacity, many transit planners view buses as key to relieving congestion. Improving reliability could turn a transportation system of last resort into one that is a feasible option. Many bus systems across the country are using systems similar to NextBus. In the Washington region, buses operated by Fairfax City, Arlington County and Prince George's County use bus arrival prediction systems.

But Metrobus, with an average of 460,000 weekday boardings, has the largest ridership by far, plus the capacity to carry many more. More riders would also increase much-needed bus revenue, officials said.

The system uses the global positioning system and computer modeling to track buses on their routes every two minutes. That information is relayed to passengers every 60 seconds via the Internet. Customers would call a telephone number, provide the number of their NextBus stop and get information on their cellphone or other hand-held wireless device telling them how long it will be before their ride arrives.

The computer modeling factors in time of day, day of the week and time of year as well as many other factors, including whether school is in session, said Rob Kramer, the Metro information technology manager responsible for NextBus. "It's a dramatic boost for our customers."

Accuracy will be thrown off, however, by major weather situations, such as snowstorms, and road closures and detours, such as during the July 4th holiday.
