AIMSUN

Aimsun is a traffic simulation software package used to model, analyze, and optimize road networks. It is employed by transportation agencies, consultants, researchers, and planners to assess current conditions and explore future scenarios.

The software supports both microscopic and mesoscopic simulation approaches, allowing detailed vehicle-level modeling as well as aggregated network behavior. It includes capabilities for dynamic traffic assignment, route choice modeling, and calibration against observed data. Aimsun also provides modules for traffic signal and corridor control optimization, incident management, and secondary effects such as pedestrians and transit interactions.

Aimsun offers an integrated workflow that includes a network editor, data import from GIS and other sources, scenario management, and results visualization. It can integrate real-time data feeds for operational use and enables export and interoperability with other tools through APIs and standard data formats. The platform is designed to support planning studies, operational analysis, ITS evaluations, and academic research.

Versions and products in the Aimsun family typically include Aimsun Next, the main platform for planning and operations, and Aimsun Live, which focuses on real-time data integration and operational decision support. The software aims to provide a comprehensive environment for simulating, evaluating, and optimizing transportation networks.
