Aimsun (originally TSS) introduced traffic micro-simulation on standard computers in the late 1980s and went on to develop Aimsun. Our latest release, Aimsun 8, stands out for the exceptionally high speed of its simulations and for integrating travel demand modelling, hybrid microscopic-mesoscopic traffic simulation and dynamic traffic assignment. Aimsun continues to innovate with Aimsun Live, the market’s only simulation-based solution for real-time traffic management. Aimsun licensees include the City Councils of Sheffield, Southampton, Leeds, and Leicester in the UK; government agencies such as NYCDoT and USDoT in the USA, and Transport for New South Wales and Main Roads, Brisbane, Australia. Leading consultancies such as AECOM, Arup, Halcrow, Cambridge Systematics and Delcan use Aimsun to deliver consultancy services, while academic users and research partners include the Universities of California, Berkeley and Massachusetts Institute of Technology, USA; Keio, Japan; European Commission - Joint Research Centre and Universities of Napoli, Italy; Southampton, Leeds and Newcastle, UK; and Queensland, Australia, allowing us to form award-winning research partnerships.
