At long last, the MBTA announces station consolidation design meeting for the Green Line "B" branch

Thursday Oct 23rd, 6pm, at BPL Copley: Commonwealth Salon.

Long time readers will recall that I have been writing about the need for station consolidation along the "B" branch of the Green Line for a few years now, in addition to articles on other topics related to Green Line operations.

It seems that the time has come for the MBTA to finally put forth a design for station consolidation within the scope of the upcoming Commonwealth Ave reconstruction project. These stations to be considered are the most closely bunched stations on the "B" branch, and clear candidates for consolidation:

The need for station consolidation on the "B" branch
Station consolidation has not been considered on the Green Line for over ten years now. The outcome of this design could result in what might possibly be the most significant service improvement in decades; a benefit for beleaguered "B" branch riders. Going from four, very closely-spaced, inaccessible stations to two, reasonably-spaced, accessible stations will greatly improve the riding experience of the vast majority of passengers.

When this concrete improvement is combined with electronic improvements such as signal priority, and organizational improvements such as all-door boarding (all the time), the result could be quite amazing. The MBTA still has some ways to go in reforming itself so that easy organizational and electronic improvements are possible to implement. But that can be done anytime. On the other hand, we won't see another chance to fix station spacing for a whole generation. This is the time to do it, and it is the time to do it right.

If you need a flashing sign then you failed at street design

In June, a speeding car spun out of control and killed two pedestrians walking on Beacon Street in the Back Bay. More recently, police arrested a man caught operating his Maserati at 100 mph on the same street. The city has responded by putting a sign on up Beacon Street near Clarendon:

Too little, too late

Charles Marohn has spent several years traveling the country, talking about the dangers of streets that are overbuilt for speed. Beacon Street is a prime example:


The sign says "30" and the street says "FAST".

Each of the three travel lanes on this street appear to be at least 11 feet in width, all going in the same direction. According to MGL Ch90 Sec17 the speed limit for a "thickly settled district" is 30 MPH. Yet, when looking at this wide open expanse of asphalt, is it any surprise that the speed limit is routinely flouted? A speed limit that is already set too highThe chance of a pedestrian being seriously injured or killed if struck by a car is 45% if the car is travelling at 30 mph but only 5% at 20 mph.

Jeff Speck has recently written an article calling upon all cities and towns to replace their 12- and 11-foot travel lanes with lanes no larger than 10 feet. This article is timely. Boston continues to design streets with 11 foot travel lanes, like Beacon Street, and the new design for Commonwealth Ave. This decision to build wide, highway-like lanes is a terrible mistake, with disastrous consequences for anyone not surrounded by two tons of steel. On Comm Ave, the city is actually planning on a 35 MPH design speed, even though the speed limit is 30 MPH, and the city itself recommends 25 MPH as a limit.

Boston has an unfounded belief in tiny, barely noticeable signs.
By designing and building such high-speed roadways, it's almost as if the city is encouraging drivers to break the speed limit. The situation would be ludicrous if it weren't so deadly serious. If Boston officials truly want safer streets, and I believe that they do, then it's time to reduce design speeds on all upcoming and future street plans. And for Beacon Street, it's long past time to re-stripe smaller and fewer lanes. That street may not be up for reconstruction for a while, but that's no excuse not to do some planter and paint-based interventions in the meantime.

A quote from the Globe:
Sam Wallace, president of the Neighborhood Association of Back Bay, who lives in a condominium at the scene of Saturday’s crash, said speeding has become commonplace recently and pedestrian safety in the area is a major concern among the residents.
“This is no longer Beacon Street; it’s the Indianapolis Speedway,” Wallace said. “The noise, the motorcycle races, the car races. And the later it gets, the worse it is.”
A flashing sign does nothing. The city must face the fact that Beacon Street, and many like it, are overbuilt in favor of speed. That is the problem that must be resolved.
