Abstract<br> <br> The main task of road engineering survey is to provide detailed and accurate survey materials for road design, so as to make its design reasonable, economical and applicable. The essence of road engineering survey is to serve the smooth construction of each stage of the project, which is divided into initial survey and fixed survey. At each stage, technical data must be provided for design, construction and operation to ensure the feasibility and accuracy of design, the correctness of guidance and supervision, and the safety of operation and management.<br> This paper combines the development and application status of curve lofting in road engineering survey at home and abroad. Through the research on the calculation method of the coordinates of the encrypted points in curve lofting and the method of lofting the coordinates by using total station and RTK, the accuracy of the data collected in the experiment is analyzed, and the process of calculating the coordinates of the encrypted points in curve lofting by computer software programming is described in detail, and the design and implementation process of curve lofting in theoretical road engineering survey is explained in detail. The process starts from the order of straight line, circular curve and transition curve, and each step is analyzed in detail.<br> <br> <br> <br> Keywords: road survey; Curve lofting; ; Calculation; program
