Aimsun is a leading international provider of software and services for traffic planning, simulation and prediction.
Acquired by Siemens in April 2018, Aimsun continues to build on over 20 years of experience in algorithms, software and operational know-how for mobility applications. The team of 80 highly qualified employees is based in offices in Barcelona, London, Paris, New York City, Singapore and Sydney, serving over 5000 licensed users in 80 countries.
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.
