Transient behavior of a passenger's body standing within a bus at sudden stop is estimated based on finite element method. The purpose of this study is to estimate the effects of the velocity of the bus, the grip force of the passenger, facing direction and friction between shoes and floor on the falling behavior of a passenger's body at sudden stop. The bus model is made to represent the arrangement of a bus used for local transportation. The human body model is made to represent aged woman of about 70 years old, based on the human body scantling database of AIST Japan. As the first step of simulation, gravity effects are applied to the whole model. Then, initial velocity is applied to both the bus model and the human body model. The bus model collides with the barrier model to simulate the sudden stop of the bus. The FEM code LS-DYNA is used for current simulation.
