__Editor Tracking__ (`created_date`, `created_user`, `last_edited_date`, `last_edited_user`)

__Functional Class__ (`domi_class`)

A general classification system used by the Department of Mobility and Infrastructure to stratify roads by significance.

* • Principal Arterial - Roadways with high traffic volumes such as interstate highways, freeways, and expressways; frequently the route of choice for intercity buses and trucks.
* • Minor Arterial – Roadways that serve trips of moderate length and smaller geographic areas than principal arterials.
* • Collector – Roadways that “collect” traffic from Local Roads and connect traffic to Arterial roadways. Typically, shorter than Arterial Routes but longer than Local Roads. Collectors provide traffic circulation within residential neighborhoods as well as commercial, industrial, or civic districts.
* • Local – Roadways that provide direct access to adjacent land, not intended for use in long distance travel. Locals roads provide access to higher systems, and typically don’t carry through traffic movement.
* • Alley - Streets intended to provide access to the rear or side of lots or buildings in urban areas and not intended for the purpose of vehicular through traffic.
* • Park Road – Roadways that provide access into and through parks.
