Description

This study aims to evaluate evacuation safety using an evacuation behavior framework which deals several evacuation behavior models. In this paper, we implemented two crowd walking models, namely, the Social Force model and the RVO model. The Social Force model is a dynamical model which solves Newton's motion equation. On the other hand, the RVO model is an expanded model of velocity obstacles for collision avoidance. When we try to understand the characteristics of these models, the results are as follows. If the desired speed of the agents are over 3.5 m/s, the flow coefficient of the Social Force model declines because of increasing the frequency of arch actions. However the flow coefficient of the RVO model does not decline. As regards an application to the evacuation from a building, the flow of a room decline because of the crowded corridor.
