We study the use of cubic spline interpolation to represent the center-
line of a road, for curves in both 2
and 3
. We look at algorithms to
create a representation based on arc length and evenly spaced nodes along
the centerline. We also consider methods for moving between rectangular
coordinates and coordinates based on distance along the centerline and
the offset from that centerline (in 2
) and a related decomposition in 3
1 Introduction
In road vehicle simulation, we need a way to describe the road. The usual
