Abstract :Traditional highway design procedure is a trial and error process where the system manager spends a lot of time. To improve this manual process, a new method to design highways is investigated. A mathematical function called Bézier Curve is used. Highway designs have been made with both traditional and Bézier Curve methods on a level type terrain. According to results, Bézier Curve gives a shorter highway than traditional method. And, the curve radius is also larger than traditional method which help improve highway safety and drivers` comfort. So, the highway designed with Bézier Curve reduces overall roadway length and larger curve radius than traditional designed highway.
