A new method for fitting the horizontal alignment of a road to a set of (x, y) points is proposed in this article. The proposed method describes the horizontal alignment as a sequence of headings unlike current methods that represent road alignment through curvature.These points are obtained from digital imagery or global positioning system (GPS)-data collection. An analytic-heuristic approach is introduced and the proposed method produces unique solutions for complex horizontal alignments. Researchers and departments of transportation could obtain accurate geometric features using the solution. However, the solution may not be accurate enough for road redesign. The article presented case studies using the method.
