Road Classes

Road Class (ROAD_CL/ROAD_CLASS) is a combination of a variety of conditions: Ramp, Ferry Type, Controlled Access, Intersection Category, and Functional Class.

Ramp (Ramp) indicates a ramp that is a connector that provides access between roads that do not cross at grade: N (Not a ramp) or Y (Ramp).

Ferry Type (FerryType) indicates whether a link is or is not a ferry link. If the link is a ferry link, Ferry Type describes if it is a boat ferry link, or a rail ferry link: H (Not a Ferry), B (Boat Ferry) or R (Rail ferry).

Controlled Access (ContrAcc) identifies roads with limited entrances and exits that allow uninterrupted high speed traffic flow: Y (Controlled Access) or N (Not Controlled Access).

See Intersection Categories for details about Intersection Categories (INTERSECTION_CATEGORY).

See Functional Class Codes for details about Functional Class (FuncClass).
