    MBTA Buses & Infrastructure

    Re: 79 / 350 to Alewife vs Davis Does the bus lane on Mass Ave in Arlington make a reroute to Davis less attractive?

    MBTA Buses & Infrastructure

    Re: Mass Ave / Western / River / Magazine / Green St / Central Sq in Cambridge / 47 This might be a reasonable cross section to end up with for the crosswalk on the south side of Mass Ave at Western / River / Magazine: from west to east: southbound bicycle lane, southbound automobile travel...

    General MBTA Topics (Multi Modal, Budget, MassDOT)

    If Congress St got bus lanes from Haymarket to Purchase St and Summer St got bus lanes from Fort Point Channel to Reserved Channel, would extending 92/93 along Congress St to South Station and then along Summer St and D St to Silver Line Way and Flynn Cruiseport, would that at least partially...

    128 Widening

    Are you thinking of a 3 or 4 level design? It looks like the I-93 through traffic needs 3 lanes in each direction to deal with the peak hour 2011 volumes in ftp://ctps.org/pub/Express_Highway_Volumes/21_I93_North.pdf but the left turn ramps max out at 1600 vehicles in the peak hour (apparently...

    Roslindale Arboretum Gateway Path

    What if the path were lit from sunset to 8 PM or something and then after that the lights would go out?

    Peabody/Danvers Branch Rail Proposal

    If a viable Swampscott to Peabody route could be made to work, the Blue Line could have a Salem branch and a Peabody branch, sort of like how the Red Line has an Ashmont branch and a Braintree branch.

    Peabody/Danvers Branch Rail Proposal

    If the goal is to get the Blue Line out to Peabody, why go through Salem at all? Salem isn't exactly on the route the crow flies from Swampscott to Peabody. Roughly a mile to the northeast of the Swampscott commuter rail station, Swampscott Rd diverges from the commuter rail tracks. Could the...

    Re: 47 Did 47 get rerouted at some point in the last decade? I have a paper system map that seems to imply that southbound 47 used to travel along Pearl until what is probably Putnam, then over to Magazine on the way to the BU Bridge, and I would have assumed that the right way to straighten...

    Re: Mass Ave / Central Sq in Cambridge Immediately to the west of Pearl, if there's no need for a westbound bus lane separate from the westbound general purpose travel lane if the traffic signal can get other traffic out of the way of buses, it probably also becomes possible to give the...

    Silver Line to Chelsea

    After watching the video, I looked at Google Maps typical traffic a bit and was surprised that the Tobin seems to stay green weekday afternoons. Page 6 of ftp://ctps.org/pub/Express_Highway_Volumes/01_Route_1_North.pdf has hourly traffic counts for the morning peak from 2007. I was surprised...

    Silver Line to Chelsea

    About a dozen people did a race trying out five routes from the Boston Common to Bellingham Sq. https://docs.google.com/spreadsheets/d/10vQ4Jd3YS0eesgByH92WouL3oO7ZjFhKAJi1Ow8F--0/edit#gid=0 has results, with Blue Line to 116/117 consistently being slowest (probably due to poor headways)...

    Yes, thanks for your help in pointing out that there is a URL ending in .png if you isolate just the image. (I'd been assuming that there was a URL that didn't end in .png which was nevertheless a png or other well known graphics format file, which can happen since HTTP has a Content-Type...

    MBTA Buses & Infrastructure

    Re: Mass Ave / Central Sq in Cambridge On further thought, I think an Essex St traffic light would probably be overkill. Instead, when a Harvard bound bus is approaching Pearl St, the Pearl St light could be set up to stop the right hand lane to store the automobiles that want to proceed on...

    Mass Ave / Central Sq in Cambridge In March 2018, Ari posted updated thoughts on Mass Ave from the Charles River through Central Sq Cambridge is planning to do a quick build reconfiguration from Memorial Drive to Sidney St at some point in the next few months. Looking at Ari's visuals has...

    MBTA Buses & Infrastructure

    On Everett's upper Broadway, the southbound bike lane that the paint shows when cars are allowed to park is pretty non-ideal in terms of how close bikes end up to cars, but there probably isn't a better solution available while maintaining 11' lanes and the current curb to curb distance (and I...

    How to post an image

    Does the forum software look at the file name extension in the image URL? I'm wondering why a firefox screenshot doesn't seem to work when I try to put https://screenshots.firefox.com/4BhUuARXTshXiJWz/streetmix.net inside an img tag: (If you start the reply process may be able to see the img...

    Silver Line to Chelsea

    A shoulder bus lane on 1A from the Winthrop Ave ramp to Boardman St might help both this detour and a bunch of express buses, but it would require some pavement widening.

    MBTA Buses & Infrastructure

    I'm fairly sure I've seen something in some news article indexed by news.google.com at some point in the last several years that there was one diesel bus being used for one or two trips a day on one of 71 or 73. IIRC it was morning only, and the article cited increasing traffic delays and...

    MBTA Buses & Infrastructure

    I observed a diesel 72 in the Harvard busway with exactly one headlight on not so long ago. IIRC there aren't enough trolleybuses to cover the weekday peak for just 71 and 73 anyway; if battery buses are now being produced in bigger quantities than trolleybuses for the North American market...
