functionalClassification

A numerical value indicating the functional classification of the road segment corresponding to the span.

Classification values are part of the hierarchical network that helps determine a logical and efficient route, and have the following definitions:

• Roads that allow for high volume, maximum speed traffic movement between and through major metropolitan areas.

• Roads that are used to channel traffic to functional class 1 roads for travel between and through cities in the shortest amount of time.

• Roads that intersect functional class 2 roads and provide a high volume of traffic movement at a lower level of mobility than functional class 2 roads.

• Roads that provide for a high volume of traffic movement at moderate speeds between neighborhoods.

• Roads with volume and traffic movement below the level of any other functional class.
