The dynamic interaction of bridge-traffic system is dependent on the stochastic characteristics various parameters that are random in nature, such as surface roughness, traffic flow, and so on. It necessary to include these uncertainties analysis. In this paper, coupled vibration studied considering flows roughness. parameters, extrapolation maximal displacement mean value process, firstly presented probability Two vehicle models, one with 18 degrees freedom (DOFs) other 3 DOFs, were adopted simulation. A cellular automaton (CA) model simulate bridge numerical investigation shows that: (1) distribution vertical lateral displacements generally remains stationary; (2) responses at different time under have negligible correlation; (3) strictly monotonically increases growth design period.
