This research related to the reappointment of the main roads and railways in the event of loss (Axis elements in the horizontal projected: Straight lines. Circular curves. Between these two elements are introduced Transit Curves), and also rehabilitation, commensurate with the developments taking place in the present time. The program is designed to also facilitate this work using the language of MATLAB. There are several questions present themselves: - What are the requirements for work (Field or desktop)? - What are the proposals for the development of the current reality of the road network and railways in the study area and rehabilitation? - What are the tools that allow transfer of theoretical study to a realistic work progress on the ground?
