Maren Maus: Calculation of capacities in railway networks under the consideration of network effects


Capacity calculations are essential for the long-term planning of railway infrastructure. The calculations are influenced by many different parameters such as the train mixture, the delay behavior and the intended operational quality. Many of the methods currently used in practice calculate characteristic capacity values separately for the single elements of a railway network, namely lines, track groups and route nodes. Due to the different calculation approaches, the determined capacity values are not directly comparable with each other and interactions with the surrounding infrastructure elements are not sufficiently considered.

In this project an optimization model that examines the possible capacity utilization of railway lines and nodes while taking network effects into account is developed. To quantify network effects, the resulting capacities are compared to the values of the single elements calculated via the state-of-the-art methods.
