Key MBTA Bus Routes

[TheBostonian]

There are some MBTA bus routes that run much more frequently than others. Waverly Sq. to Harvard Sq. #73 almost never has a scheduled headway greater than 20 minutes. 71 and 39 are up there too. What others are there?

Someone mentioned that the MBTA once considered putting together a map with key bus routes. Anyone know any more about this?

Edit: 77 is very frequent.

In some corridors, such as between Forest Hills and Roslindale, so many bus routes run together that the combined frequency is very high.
