I think there are several options that might have the potential to work:

  • Widen the street (difficult just north of Bowdoin St, where taking the parking on the east side of the street instead might make sense; and perhaps not ideal for pedestrians crossing Broadway)
  • Eliminate a northbound travel lane along part of lower Broadway; this might be especially likely to work north of Beecham, but even everything north of Dexter might work if half the afternoon traffic coming across the Mystic learns to take Dexter to Robin to Beacham.
  • Reversible lane on lower Broadway
  • Reallocate the right hand southbound lane north of Beacham to be bus only; this would have the unfortunate side effect of pushing the single occupancy vehicle storage queue back toward Sweetser Circle which might be a fatal flaw with this approach, but the number of vehicles flowing south across the Mystic from the light at the Dexter / Broadway intersection probably wouldn't change much from what it is now, and Broadway from Beacham to Dexter with two lanes and barely more than one lane feeding it would probably flow rather freely.

I think it might be appropriate to think of Chelsea to Cambridge via Sullivan as radial, in the sense that it is roughly a straight line from a largely residential area to an employment center.

I think the route you're proposing makes sense as long as it doesn't cross Chelsea Creek and it becomes a second route along the busway instead of an extension of the initial busway route. The new route could be Eastern Ave to Sullivan, or it could possibly continue past Sullivan into Cambridge to connect to the Red Line.

If the casino wants good bus service to the airport, a route via Beacham and Meridian may make sense, although congestion on Beacham probably makes that challenging, and finding space for a bus lane on parts of Beacham is probably hard, so making that work would probably require a congestion toll on the highway 99 bridge across the Mystic. Given traffic congestion and the movable Chelsea Creek bridge, though, a ferry might also work. On the other hand, an airport to casino bus stopping at each terminal and terminating at the casino so that it can pull all the way into the casino facility would probably work best for folks dealing with luggage. And if the casino runs their own dedicated airport shuttle bus that makes limited or no intermediate stops, they could possibly also use Beacham when it isn't congested, and 2nd to Broadway in the morning if the casino's private airport shuttle ends up being allowed to use the Broadway bus lane.

Isn't the casino going to provide airport service via its fleet of private water shuttles? I thought the shuttle loop was Wynn Casino; Long Wharf; Commonwealth Pier (Seaport); Logan Water Taxi Pier; Wynn Casino.

Re: Silver Line to Chelsea

What would the running times be for SL to Malden vs Sullivan? Maybe it would make more sense to just run it to Sullivan as there are plenty of radial bus lines that serve Everett and Chelsea. The circumferential SL wouldn't really work as radial as the trip around down to South Station would be much longer than just a bus ride to the OL.

Re: Silver Line to Chelsea

Two questions:

1. Has the MBTA received all the buses they'll need for this line?

2. Will they do the 60' to 40' bus switch when it gets dark or slippery?

1. Not yet. The DMAs are still being refurbished, with only 11 buses left to go.

2. No. The DMAs have powered center and rear axles, which greatly improves traction. When the roads outside are slippery, they are the only 60 foot buses that are not pulled off the road and, sometimes, one or two will sneak onto the other routes that are normally covered by the other 60 foot buses. In addition to all this, diesel exhaust isn't allowed in the Silver Line tunnel, so the DMAs and the 40 foot trackless trolleys are the only types of buses allowed in there.

Do they have an official start date yet? Also, off topic, is there a place where development projects are covered?

Re: Silver Line to Chelsea

New article from TransitMatters on how giving Silver Line Way back to the Silver Line, giving it signal priority, and using its funding for more buses are all good ideas'

Re: Silver Line to Chelsea

However, I think the proposal there to buy more trolleybuses is the wrong approach; I think we should go with batteries instead at this point. It's nearly always useful to be able to run routes beyond where it's convenient to install the overhead wires.

Why doesn't the article propose to change the way the D street light works to give the buses more priority?

Their first point is a bit unsupported with detail (which the Staties would surely provide in response), but important. Baker can simply ORDER the State Police to share the ramp. Whenever he wants. Should probably be a priority for him, then.

Re: Silver Line to Chelsea

The Staties would get over it, eventually. The benefits to the public would last for decades.

If more people in the State House used transit, then you would see low hanging fruit like this addressed pretty quickly. No politician can fix the system by edict alone (and they probably shouldn't), but small changes like this could be made in short order and make a lot of peoples' lives easier, without negatively impacting anyone else.

Does this generally work with BRT? It's always been my experience that closely-spaced buses trigger a lot of jerky, stop-and-go traffic as the operators do their best to maintain a safe distance.

It seems even the author has given-up hope of that ever happening. The detection loops are there. It would just take some willpower, effort and the time necessary to get someone out there to reprogram the control box.

It's surprising to me that the semi-autonomous cruise control features that are now commonplace on passenger cars couldn't be quickly and simply be ported over to buses for this purpose.

Re: Silver Line to Chelsea

I think if you replace the rubber tires with steel wheels, and replace the concrete with tracks, you can just couple the vehicles together...

Have folks from TransitMatters tried to get Jay Gonzales to join them for a tour of the D Street light and long route SL1 takes to get from there to the Ted Williams Tunnel?

Something I noticed this weekend driving through the TWT. The trooper in front of us was heading east toward the airport. As he/she approached the open air section between the connector tunnel and the TWT, they pulled to the right shoulder, made a 180 degree turn and headed up the ramp in what would be the opposite direction of a bus heading toward the airport.

Personally, I think the buses should be allowed to use the ramp and I can't imagine a major operational inconvenience to the state police. But if this is how the troopers have been routinely using it, it would likely make sharing the ramp a non-starter from their perspective.

Interesting... I didn't realize the Staties were doing this. I wonder how common this practice is.

I can understand the argument that Police need to be able to get out of the station and into the tunnel quickly; hence, they're traditional use of the ramp (which they can share with the SL busses). An argument that Police need to be able to get back to the station quickly, and thus need the ramp closed to busses so that they can drive up it the wrong way, seems like a stretch...

^ Well if that's what they need then just throw a cop-only cross-over (i.e. gap in the barrier) into the median ... just like the 1000s of emergency vehicle cross-overs on highways across the country

The top of that ramp is essentially in the State Police motor pool. They're not trying to get to an emergency, they're being lazy and performing an unsafe traffic maneuver to avoid spending a whole 2 minutes on the Massport Haul Road or a whole 10 minutes going through the Ted twice.

That turn is, flatly, unsafe for the traveling public. I have no sympathy for them. The Gov should make them share the ramp just so that they can't do that anymore.

Also, it's not necessarily a non-starter. It just means that there would need to be a red light at the intersection with the haul road that the State Police dispatcher in the barracks next door would trigger to stop the bus traffic, and they'd insist on that anyway for when they want to go down the ramp the RIGHT way.
