Towards TransiTUM: A generic framework for multiscale coupling of pedestrian simulation models based on transition zones

Existing pedestrian dynamics models differ in computational effort and their ability to authentically describe human movement behaviour. Hybrid approaches combine different models to speed up simulation time and to improve the results of the simulation. Current hybrid approaches can only combine a specific set of models. It is not possible to independently change the coupled models from the hybrid approach. Furthermore, transition of pedestrians between the different models is only possible at specific entry points. TransiTUM overcomes these issues and can combine any model if provided a certain set of parameters, which are common in pedestrian dynamics (e.g., pedestrians’ positions, velocities). In this paper, the coupling of mesoscopic and microscopic scales is presented. c © 2014 The Authors. Published by Elsevier B.V. Peer-review under responsibility of PED2014.
