| Abstract: | Based on the relationship of road roughness,its autocorrelation function and its power spectral density,autoregressive(AR) model was employed to simulate road roughness of all grades,which are stipulated by the National Standard GB7031-86.The WorldToolKit(WTK) 9.0,which is an integrated cross-platform development package,was used within the Visual C++ 6.0 development environment to accomplish the visualization of the road roughness of all grades. |
