Generalized Centrifugal Force Model for Pedestrian Dynamics

TL;DR

This paper introduces a continuous force-based model for pedestrian movement that accounts for elliptical volume exclusion, accurately replicating observed behaviors in various corridor geometries through empirical validation.

Contribution

The paper presents a novel generalized centrifugal force model incorporating elliptical exclusion zones, improving the realism of pedestrian dynamics simulations.

Findings

Model shows good agreement with empirical data

Accurately reproduces oscillations and overlaps in pedestrian flow

Validated in narrow and wide corridor experiments

Abstract

A spatially continuous force-based model for simulating pedestrian dynamics is introduced which includes an elliptical volume exclusion of pedestrians. We discuss the phenomena of oscillations and overlapping which occur for certain choices of the forces. The main intention of this work is the quantitative description of pedestrian movement in several geometries. Measurements of the fundamental diagram in narrow and wide corridors are performed. The results of the proposed model show good agreement with empirical data obtained in controlled experiments.
