Abstract: This work aims to develop a method of generating a random road profile in three-dimensional space based on existing road design and classification standards and parameters, such examples being the Volvo Global Transport Application (GTA) and the International Organization of Standards (ISO). This is done by combining probability models, statistical distributions and mathematical methods of defining road curves, elevation and surface roughness through the use of MATLAB code. The proposed road profile generator code creates a road in three-dimensional space independent of vehicle characteristics and behaviour. The ultimate goal of this work is to contribute to the capabilities of modern virtual vehicle simulation systems by incorporating more random environments with respect to a wide range of established national standards to better simulate real driving loads.
