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

Our logos through time

One of the first logos


Then it went red


Then the official TSS company logo came along


Then the Aimsun logo started spinning


Then it went blue


Then we kicked that spin into shape


And we injected a bit of Aimsun Online lime green!

In 2017 we rebranded and this is the new company logo – clean, simple, and dynamic
