| Abstract: | It is difficult and complex to survey and calculate the coordinate and tangent orientation angle of arbitrary points on highway oval curve.Contacting with the engineering example,this text translates the oval curve to part of the transition curve and derivates the simple and applied computing expressions to solve this question consequently.The computing expressions can be also used in the computer programme. |
