Did you mean to say "radial" bus (into the core from outlying)?
Circumferential commutes (burb to burb) are essentially unaffected (unless they pass through the core). But passing through the core on 93/90 will remain mostly unchanged directly(but may get a little easier by car as you reduce radial car commutes).
No, I meant circumferential, though I agree the term is less precise than ideal. I'm referring to a commute that either requires a transfer from a radial rail line to a slow circumferential bus route, or otherwise requires an in-and-out trip on rail. Some examples I'm thinking of:
- Davis to Longwood
- Dudley to Kendall
- Quincy to Back Bay
If, in addition to the coming Red/Orange/Green signal and the vehicle size upgrades, and a bigger faster bus system, we also built larger park and ride facilities (structured parking at Anderson/Woburn & Riverside, Alewife, Dedham, etc., ) Where are the places or who are these people in Logwood-BackBay-Downtown-Seaport that still "must drive?"
This is what I'm talking about, right here. There's no way to answer your question about who "must drive" and where, since you've just vaguely stipulated a "bigger faster bus system." That's like saying, "if we cure all the diseases, what need would there be for doctors?" Well, realistically, we wouldn't actually cure all the diseases, so we'd need doctors to treat whichever are left over.
Likewise, we're not actually going to get a public transit system that supports every single commute, so those "must drive" commutes that will still be left over are
by definition dependent on the details of your proposed expansions of service.
Again, if we want to actually have a productive conversation, we need data.
There are four areas mentioned in the Green Ribbon Commission study (the only Boston-specific study that anyone has brought to this discussion): Longwood, Back Bay, Downtown, Seaport. I would want to know, for each area:
- the share of private car users during working hours, including carpools and rideshares
- where those journeys start and end
- the socioeconomic demographics of those users (to understand the impact a charge would have -- presumably the salaried surgeon would more easily absorb the charge than the nursing assistant on an hourly wage)
I would then want to see specific proposals for how those journeys could be accomplished, without incurring unreasonable monetary or time cost, through public transportation, along with any improvements needed to accomplish that.
Frankly, if we want to discuss congestion charges in Boston at the theoretical level (which is the most we could honestly do at this point), let's at least restrict the proposed zone to the Financial District and perhaps the West End, areas with clear and unambiguous transit access. Everything else has too many variables in terms of possible transit enhancements.
To be clear, I support congestion charges, with the universal caveat that I don't support doing stupid things. And I think it's perfectly fair to want to have the details that I've laid out above before getting onboard with the idea.
