Siemens announces decision to acquire Aimsun at Intertraffic Amsterdam 2018

  • Aimsun SL will complement the existing Siemens portfolio in the Intelligent Traffic Systems (ITS) segment
  • Aimsun to be managed as separate legal entity and wholly-owned subsidiary of Siemens AG in the Mobility Division
  • Closing completed on Wednesday 4th April 2018

Siemens has officially acquired Aimsun SL. The two companies announced the decision at Intertraffic Amsterdam 2018 (see photo) and closing was successfully completed on April 4th 2018. The two parties have agreed not to disclose financial details of the deal. Aimsun will be managed as a legally independent company under the roof of the Intelligent Traffic Systems (ITS) business within the Mobility Division.

The growing volume of individual traffic, especially in booming metropolitan areas, as well as new requirements driven by technological developments such as shared and autonomous mobility, force traffic planners and operators to take a new perspective on the mobility of the future. Data-driven solutions are considered as key to also address resource constraints and environmental protection considerations. Aimsun develops software that simulates future traffic flows in the planning phase of construction projects. Based on data, it supports its users to make more effective and efficient decisions for the realization of their projects. In daily traffic management, Aimsun has developed a software solution that uses real-time data to help to optimize traffic flows and predict as well as prevent congestion before it occurs.


“Siemens is aiming to becoming a fully integrated provider of intermodal door-to-door travel solutions. Therefore we have taken several steps in the recent past to strengthen our portfolio and competence in the growing area of digitized, data-driven mobility solutions. In combination with the acquisition of HaCon, a software provider for public transportation, mobility, and logistics, we are expanding our strong position in rail and road automation technology,” says Michael Peter, CEO of the Mobility Division.

“We are glad, that we have found a partner with whom we can continue on our path towards becoming the provider of the future ‘mobility operating system’. This acquisition is a strategic step for us to foster a strong position in the future, digitized mobility ecosystem which is increasingly depending on data-driven solutions”, says Markus Schlitt, Head of Intelligent Traffic Systems business.

“Our partnership with Siemens will further fuel our recent explosive growth and strengthen considerably our presence in the ITS vertical, namely in decision support systems for integrated corridor management and simulation for signaling optimization. The combination of our companies will also provide a platform for our software to be used throughout Central Europe and in emergent markets,” adds Jaime L. Ferrer, CEO of Aimsun.
