| Abstract: | We analyzed the basic principle of least squares method,and used the method of least squares to fit the highway planar curve.The example shows that the results are close to ones by cubic spline function and meets the requirements of highway curve design.This method simplifies the calculation process,and is practicable in the work of curve design. |
