  Planning the evacuation of people from crowded places, such as squares,
stadiums, or indoor arenas during emergency scenarios is a fundamental task
that authorities must deal with. This article summarizes the work of the
authors to simulate an emergency scenario in a square using NetLogo, a
multi-agent programmable modeling environment. The emergency scenario is based
on a real event, which took place in Piazza San Carlo, Turin, on the 3rd of
June 2017. The authors have developed a model and conducted various
experiments, the results of which are presented, discussed and analyzed. The
article concludes by offering suggestions for further research and summarizing
the key takeaways.
