Visualization--Why It Should Now Be a Basic Tool for Geometric Road Design

This paper describes how a range of visualization tools or techniques may be used in the planning and design of roads. It documents the author's experience over a period of nearly forty years with visualization and geometric design in the Queensland Department of Main Roads (an Australian state road authority). It focuses on using simpler forms of visualization for addressing road geometry issues, rather than the more elaborate forms that are used for public consultation. The paper shows how visualization enables both appearance and safety issues to be detected and addressed. It presents examples of how visualization has shown that a satisfactory result would still be achieved in cases where some of the normal design "values or practices" had to be compromised as a result of design tradeoffs. The various visualization tools are presented in chronological order of their use within the Queensland Department of Main Roads and examples of their application are given. Issues relating to the amount of use or lack of use of some of the tools are also presented. Limitations of some of the tools are discussed. Lastly, the paper looks at how future developments in visualization are likely to allow potential operational issues to be detected and addressed by refining the road geometry.
