I don't understand why DC's bus shelters don't, as a matter of course, include information on bus schedules. The bus shelters in NYC do. Each bus stop, whether or not there is a shelter, also has stop specific information about the bus schedule. (DC's schedules list the times at major embarkation points along the route. This is useful too, because you know when you are supposed to reach a certain point.)
