Abstract
The road surface is regard as a curved surface including multifrenquencies, but not a curved line extending along the road direction. Instead of common single wave description method, a digital simulation method is studied to generate an analogous road surface, in which semi-sphere shape based on brownian motion process is adopted to describe the real road fluctuation state. Digital simulation proves that the generated road curve can describe the real road state, and its digit character is in accord with the regulation specified by International Organization for Standardization.
