Abstract EN
Unidirectional pedestrian movement is a special phenomenon in the evacuation process of large public buildings and urban environments at pedestrian scale.
Several macroscopic models for collective behaviors have been built to predict pedestrian flow.
However, current models do not explain the diffusion behavior in pedestrian crowd movement, which can be important in representing spatial-temporal crowd density differentiation in the movement process.
This study builds a macroscopic model for describing crowd diffusion behavior and evaluating unidirectional pedestrian flow.
The proposed model employs discretization of time and walking speed in geometric distribution to calculate downstream pedestrian crowd flow and analyze movement process based on upstream number of pedestrians and average walking speed.
The simulated results are calibrated with video observation data in a baseball stadium to verify the model precision.
Statistical results have verified that the proposed pedestrian diffusion model could accurately describe pedestrian macromovement behavior within the margin of error.
