How fast is my model? APS: A framework to systematically assess the computational speed of pedestrian models

Abstract: A pedestrian model's computation speed impacts the model applicability. However, little attention has been given to this model property in the field of pedestrian dynamics modelling. As such, no framework exists to guide the systematic analysis of a pedestrian models' computational speed. This contribution presents the APS framework (Assess Pedestrian model Speed framework), a framework to determine the speed of (pedestrian) dynamics models. APS features three methods to assess the computational speed of an algorithm, each tailored specifically to the use case of pedestrian models. It also provides guidance in choosing the proper method or methods depending on the goal and requirements of the analysis. APS also includes a new procedure to produce test cases. By using multiple test cases, the framework ensures that the dependency of a model's computational speed on the simulated scenario is assessed systematically.
