Abstract
Pedestrian dynamics is an interdisciplinary field of research. Psychologists, sociologists, traffic engineers, physicists, mathematicians and computer scientists all strive to understand the dynamics of a moving crowd. In principle, computer simulations offer means to further this understanding. Yet, unlike for many classic dynamical systems in physics, there is no universally accepted locomotion model for crowd dynamics. On the contrary, a multitude of approaches, with very different characteristics, compete. Often only the experts in one special model type are able to assess the consequences these characteristics have on a simulation study. Therefore, scientists from all disciplines who wish to use simulations to analyze pedestrian dynamics need a tool to compare competing approaches. Developers, too, would profit from an easy way to get insight into an alternative modeling ansatz. Vadere meets this interdisciplinary demand by offering an open-source simulation framework that is lightweight in its approach and in its user interface while offering pre-implemented versions of the most widely spread models.
Highlights
Pedestrian dynamics is an active and versatile research area that attracts scientists from sociology and psychology to engineering, computer science and mathematics
While panic is considered as myth by sociologist and human behaviour scientists [9], this word is still used by many computer scientists [10, 11]
We argue that walking behavior must be modeled adequately before we can move on to modeling more complex situations, that is, before we can build a tactical and strategic level on top
Summary
We introduce the three perhaps most widely used locomotion models which are all part of Vadere. We give an overview on existing open-source crowd simulators that each support one or two of these locomotion models. On we refer to a simulated pedestrian as an agent while reserving the term “pedestrian” for the real world
