(re)designing a NKY transit map
It’s been a few months since I posted my first attempt at a transit map for Northern Kentucky, and I’m starting to get thoroughly dissatisfied with it. If you’re a designer, you’re probably pretty familiar with this feeling. You make something decent enough but every time you look at it it gets a little weaker and a little rougher around the edges. No one knows something’s flaws like it’s creator! Anyway, I need to structure my thoughts before I dive into a complete redesign of the map, so I thought I’d share them.
Here’s my initial design from October 2012:
I’m seeing this design now as the first step in creating a transit map: discovering the logical structure of the system. I realize now that I did this same thing with the frequency map, getting ahead of myself and publishing an ugly but logical framework before attempting a much more finished version:
So here are the things I’ve learned from the northern Kentucky transit mapping process so far:
- Lines through Downtown are broken into only a few classes by the the route they take and where they’re going. Thanks to good planning, those two things correspond. Lines through Downtown between Newport and Covington are distinct from lines only between Downtown and Covington.
- Because of this simplicity, only a handful of stops are actually necessary to highlight or remember.
- Similarly, routing through Covington from the bridge to the transit center is confusing but consistent for almost all lines.
- The Southbank Shuttle is a major outlier.
- Some major lines like the #25 may be too confusing to map easily and might need to be simplified for the sake of easy reading.
This map isn’t finished yet because I have some major problems with it:
- There are no borders/coasts where the rivers should be. It’s kind of disorienting, especially with the labels floating in space. Hills would also be valuable here since they’re so distinct on the south side of the basin. They really completely shape the place and act as much as barriers as the rivers do.
- The colors are very close to those I used for the night-time transit map. Is Kentucky in permanent shadow?
- The roads are all different widths, and they’re wider than the insides of the blocks which takes a second to understand if you get it at all. The intersections show up more distinctly, further adding to the confusion.
- Road labels aren’t consistently placed and may be large enough to be distracting.
- Stops straddle the road…I’m still not sure about this symbology. I wanted something that would clearly capture every line that passes the stop, but still, stops are only on one side in reality.
- The three main route classes through downtown aren’t clearly labelled.
- Because the colours seem unrelated it’s not clear that the smaller lines jumping off the shared pathways are joining them and not slipping under them or just disappearing.
- The directions of travel for the shuttle through Downtown are ambiguous, but also unnecessary. My first inclination when looking at the route is to try to figure out the direction of travel because I would assume it would be important. It really isn’t.
- The dashed/solid encoding for direction in/out of downtown isn’t intuitive.
- It’s not finished. Every line but the shuttle goes a lot further out. If the full extent isn’t going to be shown, it should be clearly indicated where lines end like I did on the frequency map.
- There’s no information on frequency or any other time-variable like span of service.
That’s what’s wrong. What’s been tried before? Here’s the official map from TANK:
I think the strongest thing on here is TANK’s logo. Clearly though this map has it’s own issues but I won’t spend much time on them here. The Downtown inset presents some of the same problems as the big map: poor color choice, unclear overlapping lines, ambiguous routing. Particular to the full map is a dramatic overemphasis on suburban and rural areas necessitated by it’s topographical accuracy.
Meanwhile, 180 degrees away, we have a largely decontextualized and entirely diagrammatic map from a few years back, completed as an exercise by TANK’s planner, Tim Bender.
It’s about as far away from the previous map as it’s possible to be, and as far as functionality goes, it has the opposite problems. Of course, this map wasn’t designed for functionality, but as an exercise in understanding system topology. Where the first is too topographically specific, this one is too vague. Where the first is topologically ambiguous, this one is precise. Where the official map is perhaps too homely to attract attention, this one might place too much emphasis on consistent design. I’m particularly loving the colored classifications of lines by type and area served.
Then there’s the frequency map I made circa 2011:
In my completely biased opinion, this is at least in theory a decent hybrid of topological and topographic accuracy. However because of the scale of this map(about a quarter of an 8.5″x11″ page) and it’s overall more simplified design, It wasn’t able to show a great many important details. Downtown Cincinnati’s and Downtown Covington’s complex routing are each treated as points for the sake of space and simplicity. Only a small diagram on the other side shows where main Downtown Cincinnati stops are. The lines themselves are pretty simplified too. The #25 for example takes a more complicated course through Covington that has been simplified here.
As a side note: I’ve had a few people criticise this map for not showing enough of TANK’s services, but I think the proportions are actually pretty generous to TANK. While TANK may serve a large geographic area, it has fewer lines, less frequent services, and serves only about one sixth as many passengers. One sixth as many people get about a quarter of the total space, a measure that disadvantages SORTA’s services.
What can we learn? What needs to be in a functional and reasonably complete map of Northern Kentucky’s transit services? These are things I’ll be keeping in mind as I work on this project over the next few months.
- Clear and simple classification of downtown routing
- Colors that tie the rest of the parts of a line into it’s downtown routing classification and…
- A clean seam between the conjoined downtown route and the individual route after it branches off, OR a downtown routing that maintains the continuity of it’s constituent lines
- Major stops that clearly identify the relevant lines that stop there and are easy to locate in the real world
- A simple way to deal with the shuttle in Downtown
- A street grid in the denser parts that can be easily related to the real world
- The final locations of park-and-ride/express stops, though not necessarily their exact routing on the highway.(You don’t get off on the highway, so where you are doesn’t matter)
- An intuitive way of explicitly dealing with one-way streets
- A clear way of dealing with lines like the #5 that double back on themselves in places
- A reasonable compromise between topological and topographic clarity
- An indication of frequency, at least to the extent that an all-day line can be distinguished from a peak only line
- Distinct topographic features like hills, rivers, and major changes in street patterns(grid vs suburban)
- …Suggestions?? What do y’all think I may be missing?
I’ll keep y’all updated as things progress!
