Parameter Estimation of Social Forces in Crowd Dynamics Models via a Probabilistic Method
Focusing on a specific crowd dynamics situation, including real life
experiments and measurements, our paper targets a twofold aim: (1) we present a
Bayesian probabilistic method to estimate the value and the uncertainty (in the
form of a probability density function) of parameters in crowd dynamic models
from the experimental data; and (2) we introduce a fitness measure for the
models to classify a couple of model structures (forces) according to their
fitness to the experimental data, preparing the stage for a more general
model-selection and validation strategy inspired by probabilistic data
analysis. Finally, we review the essential aspects of our experimental setup
and measurement technique.Comment: 20 pages, 9 figure
