Designer proposes T map based on trip time
Modern subway maps are far from geographically accurate, and the MBTA's is no exception (compare the spacing between Copley/Back Bay and Heath/Forest Hills). Peter Dunn wondered if he could come up with a true hub-and-spoke T map that provides a more useful metric for riders: The time it would take them to get from A to B:
Riders need to know which line serves which station, and where to transfer to get there, but actual mileage or accurate compass directions aren't necessary to navigate the system. A time-scale map agrees, but adds a bit of information that the rider does care about: travel time. Stations are spaced according to travel time between them. (That's the average scheduled travel time; your results will vary.)

What jumps out is that
What jumps out is that Riverside is geographically twice as far from Park Street as Boston College, yet their respective branches take the same time.
Yeah, exactly what I thought about it
What you really need to do is make an inverse-average-velocity scale map where distance AND time are taken into account.
If you map out times, but then divide by the distance covered, you would find things like the Allston St Station on the B Line (4 miles from Park St) is no longer close to equivalent to the Braintree Red Line spur (12 miles from Downtown Crossing to the end).
Reservoir - Cleveland Circle
I do like how it shows the discrepancy of time needed to reach Reservoir and/or Cleveland Circle, with both stops being fairly much in the same place.

service is always better for the burbs than the city
or how long/slow the mattapan line is compared the the suburban extension of the red line to Braintree. While they take the same time on this map, a train going to Braintree goes much further than Mattapan, but also much faster.
The commonality between these two examples is that trains that stay in Boston are much inferior than ones that serve the burbs (Newton in the case of the D line, Braintree for the red). I guess we should be happy that there is service at all, look at the difference in how far the orange line goes north into the burbs versus it stopping partway through Boston at Forest Hills.
There are twice as many stops
There are twice as many stops on the branch to Mattapan as the Braintree line. I don't suppose that has anything to do with it.
Have to make a transfer too
Don't forget.
You have to switch to the trolley. The trolley built in the 40's running on a track from the 20's.
So there's that.
And, FYI, Mattapan line services some very nice neighborhoods in Dorchester and Milton.
Another Consideration
One has to change modes of transportation at Ashmont. I expect waiting time is figured in? The trolley isn't always there to speed you on your way immediately.
Anyway, the total time given is about one minute between stops from Butler on, isn't it? That's about right - even less, in some instances.

the version that lets riders select the epicenter
I want the version that lets riders select the epicenter and plots the rest of the system from that perspective.
This should be what you want

I'm not sure you can say the Orange Line is inferior to the GL
Whoa, so the Orange Line to Forest Hills is inferior to the D-line to Newton (and the D-line goes faster?). I'm not sure that I can make myself believe that.
Mixed up branches?
It shows Forest Hills as being time-equivalent to just before Brookline Village.
Seems pretty accurate to me
Considering Green Line delays and the need to wait for the Riverside branch vs catching any train to/from Forest Hills.
Apples/oranges
That's really comparing apples & oranges, though. Of course an express line can cover more distance faster than a local line. The D line operates more like a commuter rail line, with a dedicated track that doesn't interact with street traffic, and has fewer stops along the way. The B line has 5 more stops, and operates on city streets, subject to traffic lights.
But given the debacle with
But given the debacle with traffic light priority along Beacon Street, it's clear the T has no desire to speed up the surface Green Lines. Imagine if trains got priority when approaching traffic lights about to turn red. Imagine if there was pre-payment or true proof-of-payment. Then maybe it would not take 40 minutes to go all of six miles.
Kind Of The Point
It shows that one line is an apple and the other is an orange. That's the valuable information.

Old Boston joke...
Should we walk, or do we have time to take the T?
so, if im tripping.....
that map is freaking me out dude! has anyone fallen in yet?

I keep seeing the big bird from the Nazca lines....and hearing Leonard Nimoy's voice.
Since we're supposed to
Since we're supposed to pretend the Silver Lines are rapid transit, let's get them on there as well.
26 minutes from South Station to Terminal E, versus 21 minutes from GC to Wonderland on the Blue Line.
19 minutes from DTX to Dudley, which on the Orange Line gets you all the way to Forest Hills.
The T time map: a case of the wealthiest getting the worst?
The thing that jumped out to me was the time per mile on the Green Line vs. the Orange Line and Red Line (I don't think that the Blue is long enough for a comparison).
I don't have the numbers, but I'd be willing to bet that the ridership of the C and D lines has the highest average income per rider (North side of the Red Line might be close, but as I say, I don't have nor do I know where I could find such numbers).
In any case, I think that if we measured the distance from DTX to Forest Hills on the Orange Line, and then found the stations on the C and D branches with the same distance from Park St., I think that we'd be able to say pretty clearly what I said in the subject line.
If this verified, it would be an interesting reversal of how things usually go.
No need to guess

pity the plutocrats
If it's true higher income areas are less well-served by public trans, would they come if we built it?

You even went through the bother of extracting the relevant pieces from the citation you provided and some idiot had to go and ask where you got it from...jeez people are stupid...oh, wait...
thanks.
Pity the D-Liners
I'd say you'd also have to figure in how that speedy Orange line from DTX to Forest Hills got there in the first place -- it was taken from one working class neighborhood and put into the blasted wasteland that had been another working class neighborhood which was plowed under for a highway (that didn't get built). I think these folks paid their transit dues for that Orange Line that is slowly rotting away (and don't mention the Silver Li(n)e to that other n'hood, unless you want an earful).
Train frequency is also an important factor...
An interesting variation might also integrate average train frequency, as it is different on every line/branch.
