The following function returns the closest point on a Lane Plan.
To iterate along a lane on a Lane Plan, the following functions can be used:
These functions increase the point index up to the end of the Lane Plan Lane, and then automatically jump onto the next Lane Plan Segment, if there is one that has a lane that connects to the current lane.
The following function computes the distance between two points on the lane plan. However, it returns a result only when the two points are connected without lane changes.
