About Aimsun

We have a single focus on algorithms, software and operational know-how for mobility applications in strategic transport planning, traffic engineering and mobility management.

Aimsun company history

Follow our journey from a university research lab team to an international mobility software and services company.

1989-1997

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).

1997

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.

2000

Release of GETRAM 4.0

2002

TSS moves to a larger office on c/París in central Barcelona and begins to grow, steadily bringing in new developers – many of whom are still with us today

2004

TSS moves to a larger head office in Barcelona on Passeig de Gràcia. There are separate departments for Development, Projects, Marketing, Accounts and Management
