Experiment driven models for pedestrians and crowds

Cécile Appert-Rolland (LPT – U-Psud Orsay)

The growing interest for crowd modeling has led to the development of various types of models, in part inspired by fluid mechanics.
However we are still lacking full knowledge of pedestrian behavior throughout all the scales (from individuals to crowds, from low to high densities, etc).
In this seminar I will show how experiments can be used to develop or improve microscopic or macroscopic models. Several series of experiments will be reported.
Some, performed in Rennes, deal with interactions at low and moderate densities (PEDIGREE and PEDINTERACT Project) while other ones, performed in Orsay and in Argentina (PERCEFOULE Project), have provided intriguing observations of high density crowds that question current models.
In another perspective, models can be useful to scan the mechanisms responsible for, for example, pattern formation occurring at the crossing of perpendicular pedestrian flows.
