We report some experimental study of the behavior of pedestrians when they follow each other. In the frame of the PEDIGREE project, trajectories of pedestrians walking along a one-dimensional path were tracked through a high-precision motion capture. Data analysis allowed to obtain the fundamental diagram at different scales. Two unexpected transitions in the way pedestrians follow each other have been evidenced. The interest of the experiment is to capture at the same time microscopic and macroscopic characteristics of the flow. Indeed, macroscopic structures such as stop-and-go waves can also be studied from the data. Eventually, a data-based following model has been proposed. Its calibration/validation can be performed both at the microscopic or macroscopic level. It is possible to extend the model to quasi-one-dimensional flows for the modeling of pedestrian flows in corridors.
