Aimsun is a software company that provides simulation software and services for transportation planning and traffic management.^[1]

Overview

Aimsun was founded in 1997 and developed Aimsun Next traffic modeling software, which simulates mobility in networks.^[2]

Aimsun also develops Aimsun Live, which is a simulation-based traffic forecasting software^[3] as well as Aimsun Auto for studying path planning in driverless vehicles,^[4] and Aimsun Ride for modeling demand-responsive transportation services.^[5]

Aimsun was acquired by Siemens in 2018 for an undisclosed sum, as part of the Siemens Mobility Intelligent Traffic Systems (ITS) unit.^{[6] [7]}

In 2021, Siemens Mobility carved out the Intelligent Traffic Systems (ITS) unit, of which Aimsun is a part, and renamed it Yunex Traffic.^[8]

In 2022, Italian infrastructure group Mundys (then known as Atlantia) bought Siemens' Yunex Traffic division for 950 million euros ($1.1 billion) to expand its transport services, making Aimsun a part of the Mundys group.
