HERE Lanes Data Specification

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 Links and Nodes (Road Centerline Model), and as Lane Groups and Lane Group Connectors (Lane Model):

Figure 2. Lane Group Representation

We logically "glue" the two models together, in both directions. Each Lane Group Connector (Lane Model) has a position on a Link in the Road Centerline Model. And every portion of a Lane Group is associated with a Link in the Road Centerline Model.
