Summary

 

Aimsun is a 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 level of 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

Good Example

PanAm Toronto 2015 Games - area model: Mesoscopic model of Toronto Area, time-shifted traversal matrices and adjusted subarea matrices. The modelling team imported the whole Greater Golden Horse Shoe area into Aimsun from the Land Information Ontario GIS system. From this model, the team extracted the mesoscopic subarea and then developed trip tables for the traversal area using the time it took vehicles to get to the subarea.

Input Data

OD matrices, counts, signal timings, public transport schemes, transport network (topology)
