![]() ![]() It has been argued that the speed-density diagram of pedestrian movement has an inflection point. This inflection point was found empirically in investigations of closed-loop single-file pedestrian movement. I use Manjaro if you are so interested what Lin I use also. No, if you are asking if Im that user, Im not, I messaged you on fb but I shared some more here. edit: apps windows have gray background and they are shown until 'Application stopped' finishes. The reduced complexity of single-file movement does not only allow a higher precision for the evaluation of empirical data, but it also significantly simplifies analytical considerations. Proceedings 5th MATHMOD Vienna, February 2006 (I.Troch, F.Breitenecker, eds.) Object Oriented Modelling in Mechatronics 2 - 3. It runs on Linux but in about its MathMod-10.1. This is especially true if one assumes homogeneous conditions, i.e. Appropriate methods and tools are requiredto perform plant-wide simulation of the control-relevant dynamic behaviour, with time scales ranging froma few up to a thousand seconds nonlinear models based on first principles are employed, in order todescribe the whole operating range, possibly including off-design conditions. neglects temporal variations (consider time averages, neglect stop-and-go waves), individual differences of pedestrians (all simulated pedestrians have identical parameters) and investigates only steady-state (not the initial phase). As will be shown in this contribution one then can make a transition from the microscopic to a continuous and macroscopic perspective.īuilding on that it will be shown that certain (common) variants of the Social Force Model (SFM) do not produce an inflection point in the speed-density diagram if – assuming periodic boundary conditions – infinitely many pedestrians contribute to the force computed for one pedestrian. It will furthermore be shown that if – in said 1d movement situation – one only considers nearest neighbors for the computation of the inter-pedestrian forces the Social Force Model in the continuous description results in the so called Kladek formula for the speed-density relation. ![]() Since the Kladek formula exhibits the desired inflection point this observation is used as a motivation for an extension of the Social Force Model which allows to transform the continuous description of the SFM continuously to the Kladek formula and which also exhibits the inflection point in the speed density relation.

It will be shown then, that this extended SFM yields astonishingly similar speed density relations as the original SFM when only a fixed limited number of (nearest) pedestrians are considered in the computation of the inter-pedestrian force.įinally it will be discussed, if also the description of the speed-density diagram for (motorized, four-wheel) vehicular and/or bicycle traffic could benefit from these measures. ![]()
