Remarks:
1. It is stipulated that the left and right sides should be distinguished by the direction of road centerline (i.e. the direction of mileage increase); Q =-1when the line element is shifted to the left; Q =1when the metaline inclines to the right; When the metal wire is straight, Q=0.
2. When the line element is a straight line, the radius of curvature of its starting point and ending point is infinite, and it is replaced by the 45th power of 10.
3. When a line element is a circular curve, no matter what line element its starting point and ending point are connected with, its radius of curvature is equal to.
