A Method to Identify and Classify the Vertical Alignment of Existing Roads
A detailed knowledge of the geometric characteristics of already built roads is necessary for various tasks related to their exploitation. However, sufficiently accurate or updated information about their geometric characteristics is frequently not available. Therefore, it is common to collect data of road geometry normally by means of a vehicle equipped with various sensors and, from the data obtained, generate analytically a geometric design that fits reality as closely as possible. There are several procedures to recreate the horizontal alignment of existing roads. However, no such effort has been made for vertical alignment. Knowledge of vertical profile's geometry is important for safety traffic studies as sight distance. This article presents a method of obtaining the geometrical elements of the vertical profile of highways through the longitudinal slope of their centerline points. The procedure has been successfully validated by its application on five rural highways in Spain.
