As you’ve probably heard, the MBTA is about to close Government Center at the end of service tomorrow for a 2 year reconstruction. I’d like to hear your thoughts on the detour maps the T created and have put in stations. To me (a self-confessed transit geek), they seem adequate, but all of my friends find them very confusing. This leads to a broader question: how should transit agencies map and market necessary detours like this? What could be done to improve this? Thanks!

Lawrence, I think you’re being extremely generous when you say that this is an “adequate” map. For me, it takes a pretty simple concept and obfuscates it with so much confusing and unnecessary information that it becomes difficult to decipher.
The idea behind the map is to show riders alternative ways to change between the Green and Blue Lines while Government Center (the natural interchange between these lines) is closed for the next two years. The MBTA’s own project webpage says this, which actually sums things up pretty succinctly:
The recommended path of travel for Green Line customers desiring access to the Blue Line is to travel to Haymarket Station and transfer to the Orange Line toward Forest Hills (southbound). Customers should transfer at State Station for Blue Line connections.
The recommended path of travel for Blue Line customers desiring access to the Green Line is to travel to State and transfer to the Orange Line toward Oak Grove (northbound). Customers should then transfer at Haymarket for Green Line connections.
It’s not exactly convenient – requiring two connections instead of the previous one – but the concept is pretty easy to understand: transfer at Haymarket and State.
You can also walk pretty easily between Park Street and State to achieve a Blue/Green transfer (I’d suggest it would actually take far less time to do this than to transfer trains twice), but the MBTA isn’t doing you any favours if you do. Unless you have an unlimited weekly or monthly pass, you’ll have to pay again to re-enter the system, which doesn’t really seem very fair in the circumstances. An act of good faith from the MBTA might be to allow out-of-system transfers at Park Street and State for the duration of the project (within a reasonable time frame, of course).
So, now that we know what the map is trying to convey, let’s see how it does.
My first – and biggest – problem with the map is the seemingly random way that it depicts the subway lines: all the lines that leave the central map area are ghosted back, except the Blue Line. Why is it shown differently? Why are any of them ghosted back at all? Ghosting a route line back like that can imply that service on that line is suspended or otherwise not operating, which is not true for any of these lines.
It’s particularly confusing for the Blue Line between State and Bowdoin, because it makes it look like all Blue Line services terminate at State. In fact, trains will continue to run through Government Center (without stopping) to Bowdoin, which will operate full-time during this project, instead of its normal limited operating hours.
The other big problem: the repetition of the station “T” icons to show secondary entrances to stations. For someone unfamiliar with Boston (hello, tourists!) these could reasonably be confused for actual, separate stations (which don’t really exist).
The entrance to State station at the Old South Meeting House is the worst offender: the denoted walking path from Park Street leads directly to a labelled “T” marker that’s almost exactly halfway between Downtown Crossing and State – looks like a station to me! The only indication for the uninitiated that this is an entrance to State is that the ring around the “T” shares that station’s blue and orange colour-coding. To my mind, the walking path should continue all the way to State through the marker. And of course, replacing the entrance “T” markers with their own, unique icon would remove any chance for confusion. An icon should never represent two separate, unrelated things!
The arrows used to represent the possible alternate routes do a solid – if unspectacular – job, but they’re surrounded by so much visual confusion that it’s hard to trust what they’re saying. It’s actually kind of frightening that two paragraphs of text on the MBTA website can do a better job of explaining the bypass than this map can – a visual medium should really be able to explain this so much more clearly than a text-based or verbal solution ever could.
In conjunction with the project webpage, which is actually pretty comprehensive, this map is just about tolerable. But for someone coming across it in a station with no other knowledge of the project – it’s awfully hard work.
