Özet

In this paper, the ball-bank device, little-known in Turkey, has been introduced and a special application has been demonstrated on five horizontal curves. A solution has been proposed for the technique's only known disadvantage of positioning, without worrying about the GPS connection and synchronization difficulties. The primary goal of the paper is only to show the application of the technique from various aspects and not to establish geometric parameters for these curves. Field observations have shown that by means of this method it is possible to estimate the curve radius, or when the curve geometry is known, for a given comfort limit, the super elevation rate as well as the advised curve speeds (being different from the design speeds).
