§ 38-60. Definitions.

The following words, terms and phrases, when used in this article and article IV, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

General. For simplicity, the definitions of this section are stated in terms of single radius curves of edge of driveways or intersecting highways. Where compound or tapers are used, an equivalent single radius curve may be used as a control guide.

Buffer area means the border area along the frontage between the traveled way and the right-of-way line within the frontage boundary lines. (See areas (1), (2), (3), and (4) in figures 1 and 2 in section 38-95.)

Buffer island means the area between the frontage right-of-way line and a line parallel to and a minimum of four foot distance from the right-of-way line extended away from the right-of-way line. (See area (5) in figures 1 and 2 in section 38-95.)

Corner clearance (C) means at an intersecting street or highway, the dimension measured along the edge of the traveled way between the frontage boundary line opposite the intersection of the two right-of-way lines and the tangent projection of the nearest edge of the driveway. (See figure 3 in section 38-95.)

Distance between double driveways (D) means the distance measured along the right-of-way line between the tangent projection of the inside edges of two adjacent driveways to the same frontage. (See D in figure 2 in section 38-95.)

Driveway angle (Y) means the angle of 90 degrees or less between the driveway centerline and the edge of the traveled way. (See figures 1 and 2 in section 38-95.)

Driveway width (W) means the narrowest width of driveway measured parallel with the edge of traveled way. (See figures 1 and 2 in section 38-95.)

Edge clearance (E) means the distance measured along the edge of the traveled way, between the frontage boundary line and tangent projection of the nearest edge of driveway. (See figures 1 and 2 in section 38-95.)

Frontage means the length along the highway right-of-way line of a single property tract of roadside development area between the edges of the property; distance between (1) and (2) in figures 1 and 2 in section 38-95. Corner property at highway intersection has a separate frontage along each highway.

Frontage boundary line (abbreviated as FB line) means a line perpendicular to the highway centerline, at each end of the frontage lines, extending from the right-of-way to the edge of through-traffic lane; see lines (1)—(4) or (2)—(3) in figures 1 and 2 in section 38-95.

Inside radius (U) means the inside or smaller curve radius on edge of driveway, used when Y is substantially less than 90 degrees. (See figures 2 and 3 in section 38-95.)

Outside radius (R) means the outside or larger curve radius on edge of driveway. (See figures 1, 2, and 3 in section 38-95.)

Rural arterial road system means a connected rural network of continuous routes, whose design should be expected to provide relatively high overall travel speeds, with minimum interference to through movement, and providing service to corridors with trip lengths and travel density indicative of statewide or greater than intracounty travel.

Rural collector road system means routes generally serving intracounty rather than statewide travel and on which average trip lengths and travel speeds are less than on arterial routes.

Rural local road system means routes generally serving to provide access to adjacent land and provide service to travel over relatively short distances as compared to collectors or other higher systems and not classified in a higher system.

Urban arterial system means streets and highways serving metropolitan activity centers, high and moderate traffic volume corridors, and providing trips of long and moderate lengths and a high proportion of total urban area travel on a minimum of mileage. Service to abutting land should be subordinate to the provision of travel service to major traffic movements. This system carries the major portion of trips entering and leaving an urban area.

Urban collector street system means streets penetrating neighborhoods, collecting traffic from local streets in the neighborhoods, and channeling it into the arterial systems. A minor amount of through traffic may be carried on collector streets, but the system primarily provides land access service and carries local traffic movements within residential neighborhoods, commercial and industrial areas.

Urban local street system means streets not classified in a higher system, primarily providing direct access to abutting land and access to the higher systems. They offer the lowest level of mobility. Service to through traffic is deliberately discouraged.
