HERE Lanes Data Specification

Lane Group Attributes Model

Lane Groups can bear the attributes defined in the subsections below:

The Protocol Buffer implementation of Lane Group attributes is documented in Lane Group Attributes.

Specification Compliance Assertion

Topology Reference Type: Lane Group Parametric Range

Format Reference: SpecificationComplianceAssertion

Definition: This attribute indicates whether a particular range on a current Lane Group conforms to certain quality compliance rules. The compliance rules are grouped into specifications, and IDs of these specifications are used as values for this attribute. The absence of this attribute in a Lane Group means it doesn't conform with compliance specifications.

Values: If this attribute is present, then its positive integer value (starting from 1) represents the ID of a specific HAD compliance level. These compliance levels are defined in Compliance Specification Levels.

Lane-Level Topology Segment Reference

Topology Reference Type: Lane Group Parametric Range

Format Reference: Lane-Level Topology Segment Reference

Definition: This attribute references a topology segment associated with a given lane group.
