It's good to see a more complete transportation strategy. Cars and highways are critical, but in a world of limited cash and space, they aren't always the best options. Roads should certainly be maintained up to good quality, and where efficiencies can be had (new interchanges, bridges, etc.) I am very supportive. But trains and bikes work for well over a million trips each day within this state alone, and they haven't got their necessary funds in a long time.
I hope with Davey's T background he has a strong mobilizing effort on Beacon Hill to be put into better maintenance, rolling stock, and subway lines (GLX, BLX, OLX, Indigo Implementation, Shorter Headways SS-128 via worcester line). Those 5 rapid transit projects in the 128 belt would do get things for mobility and economic growth.
(to the haters: yes reform T unions, bikers run red lights, blah blah blah)
