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

2005

• GETRAM becomes AIMSUN NG (New Generation), the world’s first integrated macroscopic and microscopic traffic modelling software; the package also includes integrated editing and simulation

• Aimsun Online pilot project in Singapore

2007

• AIMSUN NG drops the caps and becomes Aimsun, adding mesoscopic simulation and Dynamic User Equilibrium assignment to the toolbox of version 6

2009

• Aimsun 6.1 integrates Legion’s pedestrian simulation engine as an Aimsun plug-in

2010

• The first branch office opens – in New York City

2011

• Branch office opens in Paris, France

• Aimsun 7 includes hybrid mesoscopic-microscopic simulation

• Aimsun Online selected as platform for DSS in Interstate 15 San Diego ICM project

2012

• We open a new branch office in Sydney, Australia

2013

• Aimsun 8 incorporates full support for four-step travel demand modeling

• I-15 Integrated Corridor Management project in San Diego wins the 2013 ITS America award for Best Innovation

2014

• CTF award for Operational Efficiency Program of the Year, awarded to I-15 Integrated Corridor Management project in San Diego.

• Our UK branch opens in London

2015

• Aimsun 8.1 is launched, with a focus on enhanced visualization and version control

• Barcelona head office relocates to larger headquarters

2017

• TSS rebrands and becomes Aimsun. Aimsun software becomes Aimsun Next, and Aimsun Online becomes Aimsun Live

• Aimsun opens an office in Singapore

2018

Siemens Mobility acquires Aimsun

2019

• Aimsun expands its product portfolio with the launch of Aimsun Auto – a software platform for large-scale testing of path planning algorithms for AVs.

2020

• Launch of Aimsun Ride, for modeling on-demand transportation

• Launch of Aimsun Next 20, focused on modeling pedestrians, bikes and how we use public transportation

• Alex Gerodimos becomes new CEO.
