Functional Classification of Roads in Mississippi

MDOT Classification Waze Road Type
  Interstate    Freeway 
  Expressway    Major Highway 
  Principal Arterial    Major Highway 
  Minor Arterial    Minor Highway 
  Urban Collector    Primary Street 
  Rural Major Collector    Primary Street 
  Rural Minor Collector    Primary Street 
  Local Road    Street 


Exceptions:

US Functional Classification guidance states that county roads (CR-xxx) with a shield should be classified as Primary Street. Since several Mississippi counties number their roads vs giving them a name, and does not imply a special route class, any CR-xxx road should be classified per the MDOT FC maps.

MS-7xx, 8xx, 9xx roads should be classified as depicted on the functional classification maps. They often are not signed and are local roads that receive state maintenance.

IE., if it is classified as a Collector = Primary Street, Principal Arterial = Major Highway, etc...

When transitioning from urban to rural classification, try to make the transition at an intersection of another road classified as a primary street or greater, in lieu of a city limit. Example: https://www.waze.com/editor/?env=usa&lon=-89.96852&lat=32.62558&layers=3045&zoom=2

MS-43 would normally be classified as a Major Highway to the Canton city limit, which is one segment beyond Finney Rd. Likewise, MS-16 would be a Major Highway about a mile short of Sharon Rd. It has little effect on routing but helps improve the appearance of the map.

Mississippi Road Segment Locking Guidance

Mississippi provides the following guidance for locking roads based on segment type. Any road of a certain segment type should be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.

Segment Type Default
 Freeway  5
 Ramp  Highest Rank of Connected Segment
 Major Highway  4
 Minor Highway  3
 Primary Street  2
 Street  1
 |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-|  3

Lock segments higher than what is listed in the table (at least your editing rank) to prevent tampering with unusual turn restrictions, one-way segments, road geometry, etc...
