These are all good points that I cannot refute. I guess it’s a bit of a chicken/egg situation. The 64 is designed and operated as a commuter route - mostly feeding the red line at central with some peak period thru service to Kendall. The 68 is designed exclusively for coverage and doesn’t really serve anyone well.
Significantly higher frequency on both would/could unlock ridership growth on the corridor. But if the whole transportation system is designed around peak commuting and past performance is considered the only indicator of future growth, then yes the 64 will double-down on commuters and the 68 is doomed.
That may well be for the best, like I said, i cannot refute your points. As a resident of the area, I really wanted to be able to hop a bus to run local errands efficiently, but the network just isn’t designed for that. So I walked a lot and took my car more often than I would have liked.
Right – the 68 is basically every 40 minutes from 6:30am to 7pm, and not on weekends. Of course no one with other options is going to plan for that – they'll walk, bike, or call an Uber instead (and indeed, the route description shows that most riders are transit-dependent). If it were 20- or 15-minute headways, until 10pm at least, then we're approaching a reasonable level of utility.
I'm not opposed to streamlining some service routes if others nearby are beefed up. But those nearby routes often don't exist, either. For instance, there is no route connecting Inman Square to Kendall. We need as many connections as we can get to (the ever-growing) Kendall Square job hub.
How about 15-minute service on Beacon/Hampshire, from Porter to Kendall? The massive number of people biking on this route shows how much demand there is for transportation from the (relatively) dense housing of Somerville to the dense jobs in Kendall.
I think it's worth asking yourself, "what does this bus do and who does this bus serve?" rather than liking more buses running down a line on a map, regardless of what they're accomplishing.
I'm glad you bring this up, as I think it shows a core problem with transit planning & general urban planning in the Boston area. "Line on a map" is the most efficient route between two places. These are the routes that we need to be building up – for bus service, yes, but even more so for residential and commercial uses. Hampshire Street, for instance, is a massively transited spine directly connected to one of the biggest employment centers in the country. It should be filled with shops, offices, restaurants, and dense housing. Instead it's medium-dense housing with little nodes of a restaurant and office or two every mile or so. These inefficiencies force people to live farther away from where they work and to drive to get groceries two miles away when there should be a grocer within a few blocks. That's not going to cut it if we're serious about building a better, more resilient Boston.
And regarding general transit geometry: San Francisco moved to a fully grid-based bus system with good frequencies after moving Muni Metro underground downtown in the 70s, and the result is one of the best-used bus systems in the US. (Bus-bus transfers are easy and actually common there; not very attractive transferring from a 40-min headway route to a 55-min headway route on the MBTA.) There are too many gaps in our region thanks to poor connectivity (and other factors, of course). Let's create a bus network that finally supports dense development away from the rail lines.
