I think B39 is a good example of an improvement most affected by the congestion pricing. It's a very short route, with very few stops, and the principal part of the route being the Williamsburg bridge. The rest of both Brooklyn and Manhattan traffic affects it rather little.

What I would call this is maybe a "poster child": a specially chosen example where the result is most dramatic and clearly seen.
