* Add lateral permeability for a GTU type in the direction of the design line of the overarching CrossSectionLink.
* Therefore, the lateral directionality of one-sided permeability has to be switched for left lanes. This is done because
* the CrossSectionLink has no idea in which direction vehicles will be moving. On a 1+1 lane road with overtaking
* possibilities, the longitudinal directionality of both lanes will be BOTH. Example:
*
* <pre>
* Suppose the design line runs from left to right.
*
* =========================
*
* LANE 1L (BACKWARD) GTUs are allowed to move to lane 2L
* Permeability RIGHT is true, although vehicles will go to the LEFT...
* -------------------------
* =========================
*
* LANE 2L (BACKWARD) GTUs are NOT allowed to move to lane 1L nor to lane 2R
* No permeability defined (empty set)
* =========================
* =========================
*
* LANE 2R (FORWARD) GTUs are NOT allowed to move to lane 1R nor to lane 2L
* No permeability defined (empty set)
* =========================
* -------------------------
*
* LANE 1R (FORWARD) GTUs are allowed to move to lane 2R
* Permeability LEFT is true
