This study investigates pedestrian avoidance behaviors in a crowd. In order to appreciate avoidance behaviors in detail, the new graphic illustration method, called “Pedestrian-Perspective Movement Tracking Diagram” was developed in this paper. This illustration method packs a sequence of pedestrian movement from the pedestrian's perspective visually in one picture.
The results of our experiment show for example detouring avoidance behavior can be observed after pedestrians reduce their speed. A case study in a real railway station was also carried out applying our new method to observe avoidance behaviors in a more complex pedestrian flow.
