Detailed Description

A lane in the road network.

This is the line, that a typical vehicle is supposed to follow. Thus, if the road narrows (e.g. at a construction site) this line is supposed to describe the trajectory that the vehicle should follow. The intended direction of travel on the lane is given by the direction defined by the sequence of points forming the center line.

A lane is part of a road and mainly characterized by its center line.

It also knows about any adjacent lanes, antecessor and successor lanes. The following image will be referred to by later comments. We'll use the lane with ID 3 as reference if not mentioned otherwise.

antecessor and successor rules

For lane A to be the antecessor of lane B, the last point of A's center line has to be identical to the first point of B's center line. Any lane starts or ends at such a split/merge point. No lane can ever keep its ID after such a split point.
