Presentation of the PEDIGREE project - realization of controlled experiments on pedestrians dynamics
Dynamics of pedestrians: crowds and individuals
Cécile APPERT-ROLLAND and Jérémie DU BOISBERRANGER The response of a highway to a local perturbation (on-ramp) is taken as a test for lane changing rules. In a first stage, real data were analyzed, with a special focus on the relaxation length, i.e. the length necessary to obtain a new equilibrium among the lanes, downwards the on-ramp.
In a second stage, the set-up is reproduced with numerical simulations based on cellular automata. The analysis of the macroscopic behavior of the system downwards the on-ramp allows to point some limitations of the simulation approach.
Macroscopic relaxation after on-ramps: real data vs. cellular automata simulations
Stefan NOWAK We present first results for the calibration of the floor field model of pedestrian dynamics. The definitions of this cellular automaton model are quite simple, so even large crowds can be simulated faster than real time with modest computational effort. Nevertheless it has already been shown to reproduce the main collective and self-organisation phenomena observed empirically. Here we want to discuss its macroscopic calibration using empirical fundamental diagrams obtained in large-scale experiments.
