I may be wrong, but I don't think that the RIDE can be separate from the T and still help the T qualify as ADA compliant.
Maybe. But at least the funding for it should definitely be supplemented from health care pools and other sources that assist the disabled.
And follow up: once that happens (which I imagine it will, however long it takes), can the T then cease operating the RIDE?
I've looked into this and the answer seems to be: probably not. This is the social service aspect of it. I think that it is a very important and worthy service, but the Commonwealth needs to get real about finding a dedicated source of funding which is commensurate with the ideal that we hold as a society for helping people with disabilities live as well as the able-bodied. It's reminiscent of the 1986 law that Reagan signed which mandated emergency room stabilization of all patients who arrived at the hospital needing treatment, but did not provide any real source of funding for the mandate. In a way, the whole health care law fiasco of the last twenty years has been about finding a way to fix that contradiction.
Can anyone give a ballpark estimate what it would cost to bring the entire MBTA system up to ADA?
The Government Center modernization project is currently at $90 million, last I checked. The next major underground station that needs to be figured out is Hynes Convention Center. That may cost just as much, although it is possible that it could be rolled into some of the air rights projects that are going to happen there. Then there's Symphony, and finally Boylston that must be sorted out. I have no idea what they are going to be able to do for Boylston, it seems pretty constrained.
Aboveground, a whole slew of stations on the surface Green Line are in miserable shape. Phase II of Comm Ave includes four station rebuilds (although I hope to cut that down) and is listed at about a dozen million dollars. The BC station rebuild was pegged at $20 million but I believe that they were trying to sneak other changes to infrastructure into that project, boosting the cost.
And don't forget about bus stops. The key bus route improvement program was supposed to address some accessibility issues, and it did help a bit, but there's so much more. Curb extensions, crosswalks, clearance zones, and snow clearing in the winter, etc.
There's accessibility, and then there's real accessibility. Technically there are many places on the Green Line and on the bus network where it is possible for a wheelchair user to board the vehicle. However, it may take several minutes or more to get them onboard, using lifts or bridge plates. I don't think that this is an acceptable situation for the long term, because it is cruel to the wheelchair user to put them on the spot like that, while everyone is waiting. We have the technology and the designs which can make loading wheelchairs and other disabled users as easy as level boarding on the subway, and it should be a goal to deploy it everywhere eventually.
I haven't even touched on the commuter rail yet.
