Below are some approved mapping sources:

  • Functional Classification Layer for ArcGIS - Add to ArcGIS Basemap linked above by clicking "Modify Map" in upper right corner of ArcGIS map, clicking on "Add" in upper left corner, then selecting "Add Layer From Web", then entering this URL.

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. Each map shows roads into different road type classifications. 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:

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 Maps, 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.
