Title: DEVELOPMENT OF GEOMETRIC DESIGN STANDARDS FOR LOW-VOLUME ROADS IN CANADA
Abstract: Approximately 76 percent of the road system in Canada has been classified as rural local roads that carry low traffic volumes. In the past, a uniform set of geometric design standards for roads was not available in Canada. The lack of national standards for low-volume roads resulted in agencies developing their own. These standards may not have been compatible with the required function of the road and also had the effect of nonuniform treatment of roads between road jurisdictions. Transportation planners and designers were faced with the problem of reducing national standards, which were originally developed for a higher classification of roads, to meet economic constraints. It became evident that there was a need to find ways to construct these roads more economically and to maintain their safety and effectiveness. As a result, the Roads and Transportation Association of Canada initiated a project to develop a national set of geometric design standards for low-volume roads. A separate chapter for low-volume roads is now included in the Manual of Geometric Design Standards for Canadian Roads. A discussion is presented of the approach used to develop the geometric design standards for low-volume roads, the results and findings, and future research that should be performed to further refine the standards.
