Research and Application of Method to Special Type Road Curves Location

LIU Bo-yang;PENG Qing-tao;Aerial Remote Sensing Institute of Jilin Province;  
There are many methods to highway curves location,traditional methods such as tangent off-set method and method of deflection angle. These methods are all locating the main points of the curves first,and then conducting the details location. Since they are usually limited by the field topography,we need to find a convenient method. As the Total Station and computer are popularized and promoted,a variety of computing tools replace large and complex analysis work for engineering and technical personnel to greatly improve the efficiency and quality of work. Procedures for curve location can compute all data of lines rapidly and high precise,working with the Total Station,gives full play to the role of portable computing tools and meets the needs of fast high-precision measurement. This article focused on the design principles and process of location procedures,as well as its application to line measurement.And pointed out the inadequacy of the procedures and areas for improvement.
