| Abstract: | In course rectangular coordinates with road point of intersection as origin a circular curve function formula including connecting curve was set up, with the distance from course control points to the circular curve fitting least squares theory Iterative method was used for calculating circular curve radius approximation |
| |
| Keywords: | road control point study out circular curve |
