OneBusAway’s Washington real-time transit map app brings real-time bus schedules to Bing Maps for the Puget Sound / Seattle area. When you first open the map app, you’re shown the transit agencies with available data. It’s recommend using the Bing search bar or map control to zoom in to your location rather as the “go to this area” links keep you at a fairly high level.
Once you’re zoomed in to where you need to pick up your bus, click on “arrival times” either on the left rail or after clicking on the appropriate pushpin. Please note that not only can you see real-time schedules, you also can get directions to the bus stop, save the stop to quickly bring it up in the future, and dive into StreetSide to make sure you know where the bus stop is — all of which are benefits Bing offers over other sources of real time transit information. When you click on “arrival times”, you’ll see the real time schedule for that bus stop.
