| Abstract: | Combined with practical engineering evaluation on highway alignment,a kind of method is put forward to fit highway alignment on the basis of the cubic spline function.The precision is discussed between curve fitting and distribution of fitting nodes.Practice shows that the principle is correct;its result is suitable and credible.It provides theoretical basis for engineering design. |

| Keywords: | highway alignment curve fitting cubic spline function distribution of fitting nodes |
