About an year ago I had this idea of making my own interpretation of the Bucharest Subway Diagram. I started without too much hesitation and this was the result:

Old diagram version
It has loads of mistakes both graphically and from the information lay-out stand point: station names positioned vertically, interchange stations huge attention grabbing tool-tips, the lines were way too thick. You can probably spot some other problems that I didn’t mention. All in all I think it was a good achievement but I wasn’t pleased with the result so I promissed myself that I will make the second version.
I started by re-thinking the entire thing. I have gone through a few iterations before getting to the one that I personally consider the best of all and enjoy most. I will post the current Bucharest Subway Map just for refference so that you can understand a few it’s specifics:

Current Bucharest Subway map
As you can see Bucharest has one single ring ( yellow ) and a few ramifications. But this might be subject to change in the upcoming years because the network is actively being expanded. And this expansion is one of the main things that I took into acount while building my map.
In my previous version the ring was a circle and it seemed right but I couldn’t be sure of it before testing other options, like a square. Bare in mind that this version isn’t finalized and has some major flaws because I realized it was a dead-end and stopped developing it:

One of the layout directions
So, I thought the square ring might be better both balance wise and in terms of information layout. But the square wasn’t optimal at all because top-right side only has 4 stations and I had massive balancing issues. Given the future lines ( the orange dotted in the official subway map ) Piata Iancului had to be paralel to Pantelimon or otherwise it wouldn’t have been possible to connect them in the future. This way I had to push 2 ( Obor and Stefan cel Mare ) on the top side and keep Piata Iancului and Piata Muncii on the right side. So basically in the end the issue was that I couldn’t balance the spacing between the stations. Back to the drawing board and to the magic circle.

The final diagram
In the end I decided to use the circle and I don’t regret this decision at all. It’s so much friendlier and it’s easier to manage in terms of future map development. All the station names are now placed horizontally and there is no font weight or size difference. The lines are much thinner and easier to follow.
As a designer I wanted to innovate – I wanted to mark stations and interchange stations in a less traditional way. But shortly I realized that it’s not the best thing to get creative in this particular case because it would directly affect the degree of usability. The traditional way of marking these elements on a subway map is something that people got used to. Ofcourse, exploring is always good and I will post a few of my ideas in a separate, explorative project. But for this one in particular I wanted to keep it traditional.
Future map improvements
planning to add Bucharest districts in the background
- planning to create a Future Bucharest Subway Diagram with the new lines on it
planning to add a map legend
Any feedback is appreciated
