Same situation as provided in the question in the image shared. Suppose the spiral curve is determined to be 230 ft. Normal crown rate holds at 2.5%.  Design the superelevation transition (in other words, find the stations of A, B, C, and D on both sides of the circular curve). Find the cross slope (slope of the cross section) at station 478+00, station 477+00, and station 476+00.

Control Survey and Geodetic reductions

Control surveys or survey controls are used to establish reference points as a basis for various construction activities. Vertical and horizontal control points are to be established in a control survey to increase accuracy. After establishing the control points, all other types of surveys such as topographic, right-of-way, aerial mapping, construction layout, boundary surveys, and utility mapping can be worked upon so that control networks can be formed. The place from which the observations are made is called a survey station.
