This study is a bachelor thesis in the field of information design with focus on informative illustration. The purpose of the work was to create an easy-to-understand and easily accessible overview map of Stockholm Central Station in order to strengthen the spatial understanding of the location and thereby increase navigation. The study is based on methods and theories relevant to information design and informative illustration. The methods used in the work were observations/site analysis, interviews with tourists and unaccustomed travelers, a customer journey, and an environmental analysis. The results show a need in wayshowing systems at Stockholm Central Station and simplify the reading of the overview map. The design proposal focuses on reducing the cognitive load through, among other things, information reduction, the use of clear color coding and hierarchy, and a perspective that is adapted to the viewer´s location. This can contribute to viewers being able to read the information and understand the structure of the station, thereby creating a mental map more easily. The design proposal aims to facilitate navigation for all visitors regardless of previous experience.
