Tech-savvy Metro bus riders who have come to rely on OneBusAway.org, an application and website that lets you know when the next bus is due to arrive at your stop, were dismayed to find this week that the service didn’t work during the snowstorm.

The reason: Metro stopped feeding the datastream that OneBusAway uses to update passengers about the progress of their bus. The information was out-of-kilter, and therefore not useful, when the buses went off their regular routes and on snow routes, Metro said. The approximately 40,000 unique visitors that use OneBusAway every week just saw the published route times, not real-time information.

We probably won’t see a fix to the system over this winter, said Brian Ferris, a University of Washington graduate student and developer of OneBusAway. In an interview via email, Ferris described how he is hoping to make some changes to OneBusAway so it can deliver reroute, cancellation and service alert information through its various interfaces.

“Updating OneBusAway is actually the easy part,” Ferris said. “The hard part involves converting the information published at King County Metro’s alerts site into a form that OneBusAway can understand for automatic delivery so you just see the pieces that affect you when you are waiting at a stop. This won’t tell you when your bus is coming, but at least you’ll have a better idea of if it’s coming at all or where it might be rerouted.”

Next year, all of Metro’s buses will be equipped with GPS systems, which is one important piece of the puzzle, Ferris said. But that won’t solve all the issues: “The next big challenge is being able to communicate specific details about detours, cancellations, and delays in real-time to the mobile device in a rider’s hand when they are waiting outside at a stop,” Ferris wrote.

“King County Metro’s service alert page, the emails, the Twitter account: these are all important tools for communicating to the rider, but they are a fire hose approach that tend to overwhelm riders with information and miss them where they need it most: at the stop.”
