Transit diagrams are simplified visual representations of complex public transportation networks. For the diagram to be as useful as possible for passengers, it must be simple and understandable. This is exactly the reason why it is important to study the psychology behind the diagram and the user, and it is also important to study the way in which users interact with the diagram. Nowadays what characterizes many diagrams are simplified transport lines, distortion of real geographical relationships, color coding of lines... One of the elements that also significantly affects the user experience of the diagram is the way the station names are positioned on the lines of transit diagrams. Although many famous diagrams use different ways to display cell names, some ways are more successful and more user-friendly than others. In addition to the theoretical and research aspects, the paper also looks at the practical part of creating a transit diagram through 6 steps.
