Back in 2010, WMATA produced a 15-minute bus map that showed bus routes with frequent service throughout the day. That map was just for planning purposes, but it’s such a useful idea that I took the next step, and turned it into a more user-friendly diagram.

In addition to Metrobus routes, this map also shows other frequent bus services in the region, including DC Circulator, Bethesda Circulator, and the King Street Trolley.
