Depending on the study horizon, various methods (e.g. queueing theory, simulation, train dynamics) are used to quantify and evaluate the interactions between all subsystems. All methods are in accordance with the relevant regulations of the railway infrastructure companies. Thanks to our scientific background, we can extent the methods used, if necessary, to meet specific requirements. We are happy to present selected projects that have been worked on by our team in recent years. For a complete list of references, please contact us.
