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)
The editor should check to see if a road is a Controlled-access highway to determine if it qualifies as a Freeway .
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.
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.
