  This paper presents a study regarding group behavior in a controlled
experiment focused on differences in an important attribute that vary across
cultures -- the personal spaces -- in two Countries: Brazil and Germany. In
order to coherently compare Germany and Brazil evolutions with same population
applying same task, we performed the pedestrian Fundamental Diagram experiment
in Brazil, as performed in Germany. We use CNNs to detect and track people in
video sequences. With this data, we use Voronoi Diagrams to find out the
neighbor relation among people and then compute the walking distances to find
out the personal spaces. Based on personal spaces analyses, we found out that
people behavior is more similar, in terms of their behaviours, in high dense
populations and vary more in low and medium densities. So, we focused our study
on cultural differences between the two Countries in low and medium densities.
Results indicate that personal space analyses can be a relevant feature in
order to understand cultural aspects in video sequences. In addition to the
cultural differences, we also investigate the personality model in crowds,
using OCEAN. We also proposed a way to simulate the FD experiment from other
countries using the OCEAN psychological traits model as input. The simulated
countries were consistent with the literature.
