Abstract: Due to the very high speeds on railways and motorways, the relationship between the horizontal and vertical geometry of roads with respect to the road dynamics has become very important. In recent publications, new transition ...

Abstract: Precise leveling has been used for the determination of accurate heights for many years. The application of this technique is difficult, time consuming, and expensive, especially in rough terrain. These difficulties have ...

Abstract: This study examines the problem of the intersection of a spiral curve with a circle, which especially occurs in the design of junctions. To achieve the requirements, an iterative method which has been programmed, is suggested ...

Abstract: Layout is one of the most important missions of the surveying engineer, which aims to carry out the designed horizontal and vertical geometries of an engineering structure by satisfying the required accuracies. It is ...

Abstract: In this paper, a new transition curve to be used in the design of the horizontal geometry of routes has been examined. This curve joins two straight lines with a single element. It is an alternative curve to the well-known ...
