'''Functional Classification'''
 
The Arkansas Functional Class (FC) map is updated by the the Arkansas State Highway and Transportation Department (AHTD).  The AR Functional Class map follows the national FC categories; however, AHTD does not produce color-coded maps similar to some other states.  Instead, AHTD creates and provides as an overlay layer to the ArcGIS map the FC categories using a numerical system. To determine a roads classification, one simply clicks on the road in question, which opens a pop-up window. This window includes a number of fields but for FC purposes, the two key fields are FUNCCLASS and RURALURBAN. The key / legend for these values is as follows:
 
* FUNCCLASS
 
1 - Interstates<br />
2 - Other Freeways & Expressways<br />
3 - Other Principal Arterials<br />
4 - Minor Arterials<br />
5 - Major Collectors<br />
6 - Minor Collectors<br />
 
* RURALURBAN
 
1 – Rural (population < 5,000)<br />
2 – Small Urban (population 5,000 to 49,999)<br />
3 – Urbanized (population 50,000 to 199,999)<br />
4 – Large Urbanized (population >= 200,000)<br />
 
Using the Functional Classification layer on the ArcGIS map and checking the qualifiers on the road, the Corresponding Waze Road Type is determined via the following two tables. For Arkansas, RURALURBAN value of 1 is considered Rural. Values of 2, 3 or 4 are considered Urban. The editor should check to see if a road is a [[wikipedia:controlled-access highway|Controlled-access highway]] to determine if it qualifies as a {{Freeway}}.

{{note|a|a}} This includes ALT, TRUCK, BYP, CONN, and SCENIC US routes.
 
{{note|b|b}} Generally, default to the LOWER of the two choices. However, use the greater of the two choices if the road is between two urban areas and is classified higher in the urban area than in the rural one. If the road does not enter another urban area, then use the lower choice.
 
For example,
* A US Highway classified as a Minor Arterial is a {{Major Highway}}.
* A US Highway BUS (Business) route classified as a Minor Arterial is a {{Minor Highway}}.
* A State Highway classified as an Other Freeway is a {{Freeway}}.
* A State Highway classified as an Urban Collector is a {{Minor Highway}}.
* A State Highway classified as a Rural Minor Arterial that becomes an Urban Minor Arterial at both ends of the rural area is a {{Minor Highway}}.
* A locally-maintained road classified as an Other Principal Arterial is a {{Major Highway}}.
* A locally-maintained road classified as an Urban Collector is a {{Primary Street}}.
 
If a road is not shown on the Functional Classification layer, it is deemed as a Local Road with a Waze Road Type of {{Street}}.
 
Inconsistent switching between road types along a road is not wanted.  Consistency is key. Do not change a road type for routing sake or to make it appear on the map at a higher speed.
 
Sometimes strictly following these functional classification guidelines will generate inconsistent Waze road types at boundaries between urban and rural maps.  It is best to use the aerial maps and GPS data to find a logical location where a road should make the change in road type.  These types of changes are usually at intersections with other roads (primary street and above) and sometimes incorporate a change in lane count (2-lane road transitions to 4-lane road).  Prudent editor discretion is needed at these locations.
 
=== Dirt (unpaved/gravel) roads ===
 
The USA Standard ([[Road_types/USA#FC_cross_reference|matrix table]]) does not specify how to set unpaved road segments, so we define that here. Unpaved roads may or may not be classified in the states' functional classification system. If they are, set the road type according to the functional classification. If they are not, set the road type to Dirt Road / 4x4 Trail.
 
To stay aligned with the USA Standard, an AR County Road functionally classified as Local, or a Local street classified as a Collector, is still to be set as a Primary Street. A Local street functionally classified by the DOT as Local, is a Street. ''Otherwise, dirt is dirt.'' The majority of dirt roads in Arkansas are not functionally classified.

If the users' Waze client options are set to avoid dirt roads, they will still be routed on dirt roads functionally classified as either a Collector or Street. This is necessary to insure beginning-to-end routing should the origin/destination be on an unpaved road however, Waze route pruning will only consider these lower-priority roads (Primary Street, Street, Dirt) near the origin/destination.
 
Examples:
 
*An unpaved <u>County Road</u> identified in the AHTD FC system as a <u>Collector</u> is a <u>Primary Street.</u>
*An unpaved street identified in the AHTD FC system as a <u>Local</u> road is a <u>Street</u>.
*Any unpaved road not listed in the AHTD FC system is <u>Dirt</u>.
