We have a single focus on algorithms, software and operational know-how for mobility applications in strategic transport planning, traffic engineering and mobility management.
Follow our journey from a university research lab team to an international mobility software and services company.
Members of the former LIOS (Simulation and Operations Research Laboratory) at the Polytechnic University of Catalonia (UPC) develop a microsimulator prototype. This microsimulator is eventually named AIMSUN2 (Advanced Interactive Microscopic Simulator for Urban and Non-Urban Networks).
The company, originally known as TSS-Transport Simulation Systems, is officially founded on 11th November 1997. Technical development continues at the university lab but TSS opens an office in c/Tarragona in Barcelona, with a tiny core team dedicated to commercializing the software. TSS sells AIMSUN within a simulation environment called GETRAM (Generic Environment for Traffic Analysis and Modeling), which also contains a traffic network graphical editor (TEDI), a network database, a module for storing results and an Application Programming Interface for interfacing assignment models.
