The purpose of this study is to analyze the patterns of complicated pedestrian flow with visible pedestrian area model. The coordinates of all pedestrians at each frame is calculated.The pedestrian area is defined as the 90cm circle from the coordinates of each pedestrian. The condition of monodirectional pedestrians which forms groups is similar to the distribution of electric field, so Blobs, Meta-ball, with Bezier Clipping method is used to visualize the pedestrian area. (1) The conflict among pedestrians is reduced by the forming group of monodirectional pedestrians; (2) The pedestrian move along the edge of other group's area because he/she can't cross inside the group; (3) The overlap of group's area illustrates the conflict between groups;The condition of pedestrian flow is analyzed with visible pedestrian area model.
