This paper deals with response behavior of the high-speed-moving connected vehicles on the running road subjected to seismic excitation. High-speed-moving connected vehicles are modeled by a set of vehicle model that has 21 degrees of freedom per vehicle. Running road is modeled by masses spring, and damper that have 1 degree of freedom in each direction. We investigated the effect of running road on behaviors of vehicles. We assumed ground as running road. We employ modal analysis in which nonlinear restoring force of stopper is considered. Response behaviors of vehicles on running road were different from response behaviors excluding running road. In this study, maximum displacement responses of vehicles on running road were bigger than maximum displacement responses excluding running road. The natural frequency of vehicle was emphasized by grounds. Also, we investigated the effect that the number of cars gives behaviors of vehicles. In this model, response behaviors of vehicles were just a little different, but its difference does not greatly give the safety of the vehicles influence.
