The Lisbon Metro navigation project was updated between 1995 and 1998, before the opening of the World Expo '98 and the introduction of the new red line. Later, in 2011, the symbols, lines, and signs in the metro were redesigned. However, after many years, the navigation solutions require review and improvement. To achieve this, it is essential to generate accurate statistics and determine how well the navigation works for tourists, migrants, and first-time users while also paying attention to crowds at tunnel intersections and the overall flow of people. By studying the current wayfinding system of the Lisbon Metro, it is necessary to draw parallels with existing wayfinding in large cities with metro systems. To identify which wayfinding signs are not effective and why. Based on information design research, this study aims to identify problems with wayfinding perception and propose solutions to improve wayfinding experience in the Lisbon Metro system. Metro navigation is one of the first impressions and interactions that tourists and migrants have in Lisbon. A repeated review and in-depth analysis of the Lisbon metro navigation can help minimize crowding in some areas of the metro, reduce anxiety, and make it easier for people visiting it for the first time.engEffective navigationInformation visualizationIntuitive navigationSigns in public placesLisbon metroWayfinding systemsmaster thesis204008182
