A simple and useful Method About Alignment of Horizontal Curve

A simple method about alignment of 'horizontal curve is introduced. This method is faster and attains standards in the paper location of horizontal curve in difficult terrain. Compared with accumulate element alignment method and apartment curve alignment method, it takes only l/ 3~ 1/ 5 of their time to use the simple method of alignment to determine a horizontal curve. This method is faster and more efficient than that of the two methods above.
