29. Nav construction family base

The nav_construction_family_base consists of coverage and KPIs for all navigation construction scenarios and is inherited by scenarios in which the Ego navigates through a construction zone. The metrics can be identified by the prefix ftlx_. This is the base scenario for navigating construction, inherited from nvdx_lib_base.
