Contraflow bus lanes in London

Of course, the way to add capacity for buses on the city streets is to prioritize use of the road in favor of buses. Make dedicated lanes for buses. It's justified because you can move far more people per hour per lane in buses than in automobiles. But I think this kind of prioritization of precious street space is too controversial for elected politicians and even for appointed government officials who would have to face the wrath of the citizenry, not to mention in DC, of Congress.

(This is the same concept of prioritization that Arlington County Virginia uses with regard to the use of curbside space on the county's streets. Because their transportation plan is focused on the maximization of optimal mobility, the use of the city's streets and parking is not managed in a manner that privileges private automobile owners in the same way that most zoning and land use planning is set up to do so elsewhere.)
