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 


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, keep the HIGHER of the two classifications to the next intersection with a road classified higher than a street within the next 1-2 miles. If it is greater than a short distance, keep the classification until the intersection with the next street.

IE., if a roads classification is MH in an urban area, but drops to a mH on the rural map, and the road has an intersection/interchange with another road of PS or greater just outside the urban map, continue to the urban classification to that intersection.

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 |-|-|-|-|-|-|-|-|-|  2

Lock segments higher than what is listed in the table to prevent tampering with unusual turn restrictions, one-way segments, road geometry, etc...
