| Outline of Final Research Achievements |
A numerical simulation method was developed to analyze the pedestrian motion under the highly dense situations. Discrete Element Method (DEM) was employed to the calculation of inter-pedestrian forces. The present numerical method was applied to some problems, such as one-way and two-way flow of pedestrian, evacuation from an exit, packing of human being, and so on. It was found that the obtained results agree quantitatively with the previous experimental results. Especially, valuable information was obtained on the heterogeneity of the force acting on the dense crowd.
Pedestrian flows were recorded by a digital video camera, and were analyzed by the PIV. The walking velocity measured from a diagonal position was corrected by a 2D projection technique.
