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
2 - Other Freeways & Expressways
3 - Other Principal Arterials
4 - Minor Arterials
5 - Major Collectors
6 - Minor Collectors

• RURALURBAN

1 – Rural (population < 5,000)
2 – Small Urban (population 5,000 to 49,999)
3 – Urbanized (population 50,000 to 199,999)
4 – Large Urbanized (population >= 200,000)

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 Controlled-access highway to determine if it qualifies as a  Freeway .

Urban Functional Classification

AHTD Functional Class	Qualifier	Corresponding Waze Road Type
Urban Interstate	None	Freeway
Other Freeways and Expressways	Controlled-access highway	Freeway
Other Freeways and Expressways	Non-controlled-access highway	Major Highway
Urban Principal Arterial	None	Major Highway
Urban Minor Arterial	None	Minor Highway
Urban Collector	None	Primary Street

Rural Functional Classification

AHTD Functional Class	Qualifier	Corresponding Waze Road Type
Rural Interstate	None	Freeway
Rural Principal Arterial	Controlled-access highway	Freeway
Rural Principal Arterial	Partially-limited-access road	Major Highway
Rural Minor Arterial	None	Minor Highway
Rural Major Collector	None	Primary Street
Rural Minor Collector	None	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.
