Research on Time Series Modeling Method of 3D Stochastic Road

Based on the previous work on the road time series model,a further development toward the 3D road simulation by using double auto-variable time series method was made.The basic principle of time series model was introduced and then the present application to the road simulation and the main models were summed.Through the discussion about the digital feature of the arbitrary roads,an innovative simulation method of 3D stochastic road surface by using double auto-variable time series was proposed and the application process and the flow were analyzed.'
