We investigate running stability of the high-speed-moving vehicle subjected to the seismic excitation considering the passengers' dynamic characteristics. The analytical model of the vehicle consists of the body, the trucks and the wheelsets. The passengers are modeled as the 2-DOF system in horizontal and vertical directions. The behaviors of the vehicle and the passengers are simulated with the actual seismic input to the system. Then the possibility of the rollover of the vehicle is evaluated. We focus on the effect of the dynamic characteristics of the human and the number of the passengers when the vehicle is subjected to the seismic excitation.
