Oh sorry, I was referring to it from a geographical/distance perspective, not from a density perspective. Hence the "seems".
The 32 is a lot more detached from the rest of the Key Bus Routes network and further away from downtown Boston than almost all of them. Its characteristics resemble more of a Wonderland-Lynn route (which is hugely beneficial but does not exist among Key Bus Routes as a singular route), whereas other Key Bus Routes typically serve the inner metro area that largely aligns with the current boundaries of rapid transit lines.
Let’s break this down.
Classifying a bus route based on distance from “Downtown Boston” is a misnomer, given that Boston’s ‘central business district’ includes both Downtown Boston and Back Bay. In measuring proximity, one could use Copley Square instead of Downtown Crossing, but in reality, it makes sense to use both Downtown Boston and Back Bay, and recognize that what an outsider might refer to as Boston’s central business district stretches from roughly 1 Dalton to Bulfinch Crossing. In fact, the key bus route network (if you can even call it that) is more accurately two distinct networks, one oriented towards Downtown Boston (111, 116, and 117) and one oriented towards Back Bay (the other twelve routes).
If you strictly use “Downtown Boston” as your placemarker (and ignore Back Bay) to denote how ‘far out’ things are, you quickly run into obvious counter-examples:
- The Pru is as far out as Widett Circle
- Harvard Square is as far out as Savin Hill
- Cleveland Circle is as far out as Deer Island
This understates the proximity of the western end of the urban core.
In terms of distance from the ‘central business district’ (defined as the span from 1 Dalton to Bulfinch Crossing, where all of Boston’s 500+ ft buildings are), the 32 is comparable to the 22, 23, 28, 57, 71, 73, 77, 111, 116, and 117. That’s all the key bus routes except the 1, 15, 39, and 66, which exclusively serve the heart of the urban core more than is typical of a key bus route.
Rather, these 11 key bus routes (22, 23, 28, 32, 57, 71, 73, 77, 111, 116, and 117) all serve as major feeders of the subway system from dense inner-suburban and urban residential neighborhoods, at least some of which are 3-5 miles from the central business district and underserved by the MBTA Subway system.
The closest parallel to the 32 is the
77. Both meet the rest of the key bus route network at their terminus, a major bus hub and transfer point in general (Forest Hills and Harvard). Both function as an extension of a rapid transit line that terminates too close to the central business district. Both run from roughly 8 to 3 miles out of the central business district. Both serve as replacements for widely-used, well-established streetcar service that was bustituted in the 1950s. Both serve these ‘streetcar suburbs’ that are a mix of urban and dense-suburban when viewed through a 21st century lens. Both serve corridors that were part of their respective rapid transit lines’ extensions’ official plans within the last 50 years. Both saw these extensions/relocations instead built as stub-ends in the 1980s that terminate inside the urban core, with relatively high transit demand existing beyond the terminus.
You could also make the case that the
73 is a better parallel as much of the above applies, but in addition the 73’s lack of connection to Porter (unlike the 77), means that an even higher percentage of inbound riders alight at the terminus to transfer to the rest of the system (like the 32) and outbound riders board at the terminus to transfer from the rest of the system.
