i.e. this DF describes the lanes which are blocked by an object or event and not the position of the object / event itself. A confidence is used to describe the
probability that exactly all the provided lanes are occupied.

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.
If [**PathPredicted**](#PathPredicted) has only one element, the encoded area represents a circle with the asymmetricAreaOffset as the defining radius.
