With around 9.5m PAX a year and 400 takeoffs and landings a day to over 100 destinations, Stuttgart Airport is one of the busiest airports in Germany. The goal is to optimise the passenger traffic routing in the four terminals in order to allow passengers to reach their gate quickly and safely. The orientation system was already made more dynamic in the last few years, yet it was still worth examining where it was possible to improve the information design. After a more detailed analysis of the airport, Moniteurs advised the Terminal Management and the company management with regard to information architecture, naming systems, graphics and analogue and digital orientation signage. A flexible routing system to the security checks, in consideration of passenger capacity, was one of the main criteria. The first modules have already been implemented.
