AbstractVertical curves play a fundamental role in highway geometric design by influencing vehicle dynamics, ride comfort, and safety. Although parabolic curves are widely adopted in current practice, alternative curve formulations may exhibit different dynamic-performance characteristics. To the authors’ knowledge, limited research has examined the vehicle-dynamics implications of hyperbolic vertical curves using multi-body simulation under standard highway-design constraints. Therefore, this study compares the dynamic performance of hyperbolic and parabolic vertical curves using a CarSim-based vehicle model. The analysis covered crest and sag curves designed according to stopping sight distance (SSD) and passing sight distance (PSD) criteria under identical geometric boundary conditions.
