A framework for visualising road design prior to construction using driving simulation technologies

This paper proposes a framework where road designs can be visualised in a virtual reality environment prior to any physical construction. A software algorithm for generating computer graphics models automatically enables this framework to be effective. Key road design parameters such as the number of lanes, shoulder length, speed limits, turn angles, etc., must first be identified and then a computer program is developed to build computer graphics models based on these parameters. The generated computer graphics will include triangle meshes, textures, and height maps which can be rendered within a virtual reality environment. When used in conjunction with driving simulation technologies, the program also enables road designers to drive on their road being designed. Any implementation of this framework will be the most effective if it is incorporated with an existing road design process. Additionally, a case study is presented in order to demonstrate an implementation of the proposed framework.
