The following piece was provided by State Sen. Will Brownsberger, D – Belmont, who also represents Watertown and parts of Boston:
A closer look at recently-reported traffic numbers offers hope that expansions of rail service can make a real difference in rush hour congestion. I was discouraged by two analyses that came out over the summer. MassDOT’s report, Congestion in the Commonwealth, showed that daily vehicle volume dwarfs daily commuter rail ridership along the major radial commuting paths into the core of the Boston area. Around the same time, preliminary results from the Rail Vision model showed that even major expansions of commuter rail service outside 128 would garner ridership increases apparently too small to make a dent in vehicle volume. For example, the Congestion report shows at page 89 that on I-90 (the Massachusetts Turnpike), there are roughly 150,000 vehicles per day as compared to only 18,000 daily riders on the parallel Worcester line.
