if the component asymmetricAreaOffset is absent, the symmetricAreaOffset is applied to both sides of the position (left and right)
If the component asymmetricAreaOffset is present, the symmetricAreaOffset is applied to the enclosed side of a curve.
If the curvature of the path is 0 the offset is applied to the left handside of the path.
To determine how the lateral offset is to be applied to the path, the following steps are executed:
- For each nth pathPointPredicted (ppp_n), vectors v_(n-) and v_(n+) from ppp_n to ppp_(n-1) and from ppp_n to ppp_(n+1) are created.
- v<sup>_</sup>(n-) and v<sup>_</sup>(n+), the normalized vectors of vectors v_(n-) and v_(n+) are created.
- v<sup>_o</sup> the normalized sum of the vectors v<sup>_</sup>(n-) and v<sup>_</sup>(n+) is calculated.
The symmetrical border offset spans a vector in the direction of both v<sup>_o</sup> and -v<sup>_o</sup>, if the asymmetrical border offset is ABSENT.
The symmetrical border offset spans a vector in the direction of v<sup>_o</sup> if the asymmetrical border offset is PRESENT.
The ends of the border offsets vectors of ppp_n for each side are connected to the border offsets vectors of the endings of ppp_(n-1) and ppp_(n+1) to create the indicated zone.
