Similar to the RDNO field, but provides a universal identifier for road segments that can be referred to by all users of the dataset. (Source: Boone County GIS Department)

    SYMBOL
    Type of road segment. Used in conjunction with DISPLAYNAM and LABELNAME fields to determine which kind of symbology and label a given road is supposed to have. If the road is a highway, its label is derived from the LABELNAME field; for all other types of roads, the label is derived from the DISPLAYNAM field. (Source: Boone County GIS Department)
