Lane Road Reference Model

Both the Road Centerline Model and Lane Model represent the same real world road network. The following figures show how the same road segments are represented as segments and nodes (the Road Centerline Model), and as Lane Groups and Lane Group Connectors (the Lane Model):

Figure 2. Lane Group Representation

The two models are logically "glued"together in both directions. Each Lane Group Connector (Lane Model) has a position on a segment in the Road Centerline Model. Every portion of a Lane Group is associated with a segment in the Road Centerline Model.
