A macroscopic loading model for dynamic, anisotropic and congested pedestrian flows: Implementation, calibration and case study analysis

Pedestrian facilities are more and more congested. It is important to understand the modeling of pedestrian flows to assure safety and comfort. Many models have already been developed such as the social force modle and PedCTM. The problem is that either they allow for population heterogeneity or they are fast. The goal of this project is to implement a new model that has both of these characteristics. The new model presented here is fast due to the use of a fundamental diagram. The anisotropy of this model comes from a new formulation of a fundamental diagram based on the literature, SbFD. This project gives a summary of the model and presents the new fundamental diagram. It also compares this fundamental diagram to the state-of-the-practice, Weidmann (1992). The different parameters of the model and the fundamental diagrams are calibrated using the simu- lated annealing algorithm. Finally, a case study analysis on two set of experimental data is done to compare the performance of the fundamental diagrams.
