Studies based on the numerical simulation to understand the falling behavior of passengers on public transportation system have been carried out. Experimental verifications are necessary to understand the actual behavior and increase the accuracy of the simulation method. A carriage system on which a human subject can stand is used and collision experiments are carried out under the very low speed of 0.14m/s. The movement of the carriage and the human subject are measured with high speed cameras and an accelerometer. The variability of the collision velocity is about 10%, in spite of the carriage is driven by the human power. Mostly the variability of the measured results is about 10%. On the other hand, unexpected results, such as vertical displacements at the heel of the subject, are observed. In addition, a numerical simulation of the experiment with FEM code LS-DYNA is carried out to see the estimation accuracy of both the simulation model and the simulation method.
