| Abstract: | There are the two methods widening in the triangular and approximate tangent change for the fourth road curve in the national criterion.The precision widening formula has been derived and applied to calculate the coordinate of side peg of circlar curve with superhign and widening spiral in this paper.The digital set-out has been realized unsing the special applying program. |
