Abstract: This study investigates the optimization and analysis of vertical curve fitting techniques in roadway design. By comparing different mathematical models, including parabolic, cubic, and spline-based approaches, we evaluate their effectiveness in minimizing design errors and ensuring smooth transitions between roadway segments. Using a dataset of roadway profiles, the study applies each technique to optimize curve fitting and assess performance metrics, such as curvature continuity, vertical alignment accuracy, and computational efficiency. The results demonstrate the superiority of spline-based techniques in achieving optimal roadway designs with minimal deviations.
