Abstract

Real Time Kinematic GPS technique displays really an efficient and fast improvement within today's technological developments. The most important reason of that is one can obtain coordinates instantaneously and in the cm level accuracy by using this technique. This technique is widespread used in construction and survey areas because of its mentioned properties. In this study, the usage opportunity of RTK GPS technique in land application of highway geometry and its consequences will be observed. Therefore, the determination of highway geometry (superelevation design) and its control are very important from the view point of optic and safety conditions. For this purpose, a finished highway project will be checked by using RTK GPS technique then the certainty degree in transition of geometric standards of highway from project to land and effects on it will be examined. The obtained results by using RTK GPS are compared with the project (terrestrial survey) results and are gained centimetre level accuracy.
