The situation is really much much worse that just under-performing its ridership estimates by nearly 1/2 (doing 2,133 per day instead of 4,200).
It is 74% BELOW its estimate for new transit riders. because nearly half of riders were taken not from cars, but were cannibalized from the commuter boat!
The reality is that for $534m was "supposed" to entice 3,600 new transit riders, and it only enticed 950 which is just
26% of forecast. Even had the line cost its original $200m its hard to justify it based on this ridership
I've reconstructed the projected and actual based on the Boston Globe article (which is found here and is a "must read"
http://www.boston.com/news/local/massac ... ojections/)
Projected 3 to 5 Year Ridership:
4,200 daily
of which....
3,550 new transit users
450 cannibalized from commuter boat (forecast was for 1 boat rider taken for each 8 taken from the road)
200 cannibalized from other transit (this is unstated, but I'm guestimating from actual cannibalization)
Actual Ridership at 3 years
2,133 daily (and falling...but more like "at its likely max" if not for the recession)
of which...
950 new transit users (44.5%)
995 cannibalized from the commuter boat (46.6%)
190 cannibalized from other transit (8.9%)
$534,000,000 spent per each of 950 new transit rider is $562,000 per new rider BEFORE operating subsidy. You'd probably have gotten way better environmental benefit by giving away 200 new Priuses (for free) every year for the next 50 years (which could be funded with more like $300m, and would require no operating subsidy). Or given away 950 condos along the Mattapan High Speed line. Building this line was financial insanity.
