Based on the white noise filtration method, the time domain model of stochastic road irregularities was established including the model of multipoint time-delay correlative excitation from the same track and the model of space-coherance excitation from the bilateral tracks of a vehicle on the road. Further the development was made from the time domain model of one dimensional road irregularities to two-dimensional road surface and the simulation realization completed in MATLAB environment. The case studies demonstrated that the digital road surface characteristics simulated by white noise filt...
