Color is Better: A look at transit maps

Here in the Boston area we have what is, by American standards, a good commuter rail system.  It runs on weekends and holidays, it has a decent on-time performance, it can work for reverse commuting (trains run out of the city in the morning and in to the city in the evening, and it runs at off-peak hours for non-work related trips.  It's also really big.  I don't think its size is appreciated enough.  Why does this matter?  I believe it can affect ridership, even if only a little bit.  It's also a matter of pride and ownership.  If Boston area residents have pride in their rail system as a valued and vital resource linking their communities, then I believe they will be more likely to invest in it.  What's my suggestion?  Re-work the maps.


Here we have the standard MBTA system map.  Each purple line is a commuter rail line, running in and out of Boston through either North or South Station.  The thin, colored lines are the subway and light rail lines.  You can see how the lines relate to the bay, but the other three sides of the map might as well lead to an empty abyss.  Why not include an inset map showing how the MBTA Commuter Rail provides service to a large piece of the state?




Here we have a map of the commuter rail system from Wikipedia.  It shows the lines in purple and the area the MBTA services in pink.  The core city is a darker shade and the closer suburbs are in a middle shade.  It's not essential to the traveler, but it gives the viewer a better idea of the area the trains service.  Add a few major cities and it might give people a good impression of the system's size and all the people it can potentially service. 

This is the Copenhagen metro area transit map.  The subway lines are the thick yellow and green lines.  The regional trains are the gray lines, and the local trains are dark blue.  The most colorful lines on the map represent the S-Tog lines, the suburban train system most comparable to the Boston's Commuter Rail.  In my opinion, the spectrum of color gives you a better sense of the number of lines and their distance.


















You could argue that the MBTA Commuter Rail lines shouldn't be colored because they're part of a secondary system of lesser quality than the "T" subway lines.  It's true that the S-Tog trains run every 20 minutes all day, except for peak-hours when they run every 10.  It's also true that the S-Tog is all-electric (no nasty diesel fumes).  Still, my hypothesis is that change can work differently.  Instead of using colors to show the investments we've made, use colors to increase support for investment.


Here's an MBTA Commuter Rail system diagram in many colors, created by a Wikipedia user.  It's not a map, but it shows the lines and stations.  Doesn't it make the system seem larger?  Look at all those lines and stations!  As a Brandeis student, my station isn't just some place on a purple web.  It's a station on the red rail line.  I can look at the map and better identify the stops along my line (aka all the places the train can take me).  It's unique, it's my line.

For a fair comparison, I've provided the closest official example I could find, the MBTA zone diagram.

















Couple coloring the lines with thickening them (make them look important, like the primary means of getting around) and you've got a better map, in my opinion.  Include some more lines to show the trains that don't run the full lines (e.g. North Station to South Acton rather than Fitchburg) and it's even better.

The colors will have a different psychological effect on each person, but I believe that one thing most everyone could take from it is a greater appreciation for the wonderful resource we have in Eastern Massachusetts known as the MBTA Commuter Rail.
