This paper presents an application of the simulation system of the vehicle-occupant dynamic interaction which was developed by the author. During the application of this system, the effects of bridge expansion joint and vehicle speed on human dynamic behavior were investigated using this computer simulation system. The expansion joint of highway bridge is modeled by Fourier series function. The randam roughness of an actual highway surface has been taken into account in the simulation system. It was found that projection of expansion joint and the shape of obstacle exert a serious influence upon human ride comfort. Some results are presented in the form of parametric plots. Allowable height of expansion joint in the vehicle speed range of 40 to 160 km/h, and a standard of maintenance are presented.
