Diagram redesign
04/2024
Currently, there are two official maps: one for the tram network, and another one for the subway line. I decided to combine both into a single, comprehensive transportation map that is accessible, minimalistic, and easy to understand by all locals and tourists.
As of today, there are two official diagrams, one for the subway line and another for the tram network. Both official diagrams fail to achieve the purpose of maps and diagrams, which is to help users move around.
The diagram that displays the tram network is cluttered with information that is not useful to the user, such as highways, parking spots, or even non-existent tram lines. In addition, it lacks a clear grid, correct alignments, and consistent spacing.
Knowing what we can improve, we first can investigate what other cities’ transit networks get right.
Contrary to popular belief, transit systems use mostly diagrams and not maps to display routes and stations. Maps are loyal to geography, while diagrams prioritize legibility and simplification. They do not have to follow the exact geographic location of routes. These examples are a good representation of how transit diagrams should be designed because they all follow a few pillars:
- Legibility: use clear fonts and contrasting colours.
- Simplification: only focus on essential information, avoiding clutter.
- Consistency: maintain a consistent visual language throughout the diagram, using color size and line weight to represent different elements.
Now, knowing everything we can improve, it’s time to rethink and design the new tram diagram of Turin.
Before we can hit Illustrator, we need to establish a clear and consistent design language that is easy to remember for both people who live nearby and tourists. For instance, they can remember the route by looking at the colour of the line or number.
Starting with the typeface, Helvetica Neue is going to provide a clear and accessible look to the diagram and way-finding. It is not a coincidence that it is used in numerous transits systems around the world, such as New York.
Regarding colour, the palette must be contrasting enough with the font colour, and in this case I went with a more pastel palette to give it a new fresh look
Sizing stays consistent throughout the diagram, lines have fixed weights, margins are constant and angles are fixed at 30º, 45º and 90º.
Finally, all tram routes are assigned a number and a unique colour; also, the express bus line to the airport adopts a plane icon, and the historical tram is noted by a distinct icon.
The new tram diagram for the city of Turin has a fresh and modern look, being able to provide commuters and locals with crucial information on their journeys.
