Aimsun Traffic Simulation Software


Traffic modelling without boundaries


Aimsun is traffic modelling software that allows you to model anything from a single bus lane to an entire region. With thousands of licensed users in government agencies, consultancies and universities all over the world, Aimsun stands out for the exceptionally high speed of its simulations and for fusing travel demand modelling, static and dynamic traffic assignment with mesoscopic, microscopic and hybrid simulation – all within a single software application.

Aimsun allows you to carry out traffic operations assessments of any scale and complexity. The applications are endless but some of the most common are:

  • Assessment and optimisation of Transit Signal Priority (TSP) and Bus Rapid Transit (BRT) schemes
  • Feasibility studies for High Occupancy Vehicle (HOV) and High Occupancy Toll (HOT) lanes
  • Impact analysis of infrastructure design such as highway corridor improvement/construction
  • Environmental impact analysis
  • Toll and road pricing
  • Evaluation of travel demand management (TDM) strategies
  • Signal control plan optimisation (Aimsun-TRANSYT link) and adaptive control evaluation
  • Safety analysis
  • Evaluation of Variable Speed policies and other Intelligent Transportation Systems (ITS)
  • Highway Capacity Manual (HCM) analysis
  • Workzone management
