According to OweMalleys state page, the ridership of publc transportation in Maryland was at 350,000 in 2011. (im thinking this has to be low)

The new projects that they are talking about funding are roughly 1 billion dollars.
If you take the 1 billion dollars and figure in the cost per rider, its about 2,857.00 dollars each. Even if the new projects double the rider numbers, we are still subsizing the building of the new lines at the rate of $1428.50 per rider.
I fail to see where this is cost effective.
I would suggest finding the money in places that it can be cut from without having to raise taxes or fees again, CASA and the support of illegals comes quickly to mind. Cut all funds to CASA, then do an extensive review of all that collect social services, cut all services to anyone that is not 100% legal U.S citizen and transfer those funds over to the new projects. Then we can re-evaluate the additional funds really needed.
