Multi-Directional Pedestrian Flow Model Based on Empirical Data

This research aims at finding characteristics of multi-directional pedestrian traffic flows based on empirical data. Recently, several pedestrian models are proposed to evaluate congestion in normal and/or evacuation situations. However, not many models are validated using observed data and even important characteristic of flow is still unknown. This research has conducted an experiment to find characteristics of congestion phenomena and microscopic behaviors of pedestrians depending on one-direction and bi-directional flow. A microscopic simulation model based on pedestrian behavior observed in the experiment is proposed. The model is tested and has shown that it represents basic characteristics of pedestrian flows.
