WMATA is comprehensively reviewing many of its bus lines, such as the S1/2/4 lines on 16th. They recently announced another round of reviews including the very complex D1/2/3/4/5/6 buses. When evaluating these buses, WMATA should keep in mind a very simple principle: Keep It Simple, Stupid (KISS). Our bus map is hugely complex, and as a result, most people only know the one or two lines that they take every day to commute. Everyone else avoids buses, except maybe the Circulator.
