ROAD: Interactive Geometric Design Tool for Transportation Education and Training

Abstract

Traditionally, transportation engineering students have used engineering drawing techniques to manually lay out lines and curves over contour maps for highway geometric design. The design process requires numerous calculations of stopping sight distance, minimum turning radius, and curve alignments to minimize economic and environmental impact and construction costs. Students usually perform iterative computations to manually meet design criteria and environmental constraints. The traditional approach of learning geometric design is cumbersome and time consuming, limiting students from taking a broader perspective on geometric design. A new software tool,
