New Jersey Administrative Code › Title 16 - TRANSPORTATION › Chapter 47 - STATE HIGHWAY ACCESS MANAGEMENT CODE › Appendix D - NUMBER AND LOCATION OF DRIVEWAYS AND INTERCHANGES

Current through Register Vol. 56, No. 14, July 15, 2024
D-1 Number of Driveways
a. All lots or sites eligible for access to a State highway may
				be approved for one or more two-way driveways, as set forth in paragraph b.
				Lots or sites located on AL 2 State highways with the ability to have non-
				State highway access to a street other than the State highway shall not have
				access to the State highway. On divided State highways, two one-way driveways
				may be substituted for a two-way driveway. On undivided State highways, two
				one-way driveways may be substituted for a two-way driveway with Department
				approval based on safety or operational considerations.
b. The number of driveways on a State highway shall be
				determined as follows:
1. For nonconforming lots, the maximum number of two-way
				driveways shall be one.
2. For a conforming lot or site, the number of two-way
				driveways shall be determined as follows:
i. For a lot or site requiring a minor permit, one shall be
				allowed.
ii. For a lot or site requiring a major permit, a maximum of
				two may be allowed if, as determined by the Department, the second driveway
				will benefit the safety and efficiency of the State highway and meets the
				requirements of paragraph b3 below.
iii. For a lot or site requiring a major with planning review
				permit, two or three may be allowed if the second and third driveways, as
				determined by the Department, will benefit the safety and efficiency of the
				State highway and meet the requirements of paragraph b3 below.
3. Requirements for more than a single two-way driveway for a
				lot or site requiring major or major with planning review permits are as
				follows:
i. Two may be allowed on a midblock lot or site which has a
				minimum of three times the spacing distance between the centerlines of each of
				the next adjacent non-single family residential lots. See Figure D-1. (L## +
				R## > 3 x S)
ii. Three may be allowed on a midblock lot or site that has a
				minimum of four times the spacing distance between the centerline of each of
				the next adjacent non-single family residential lots. See Figure D-1.(L## + R##
				> 4 x S)
iii. A maximum of two may be allowed on a corner lot or site
				that has at least three times the spacing distance between the centerline of
				the next adjacent non-single family residential lot on one side and on the
				other side to:
(a) The centerline of the adjacent side street; or
(b) The centerline of the side street frontage measured along
				the lot or site frontage, when non-State highway access is provided to that
				side street.
4. An emergency driveway shall not be counted as a driveway for
				the purpose of determining the number of driveways.
D-2 Location of driveways
a. The location of driveways shall be established using the
				Design Standards and Driveway
Design Parameters found at NJ.A.C. 16:47 Appendix E and safety
				considerations based on sight distance and other geometric requirements. b.
				Driveways, whether on a conforming or nonconforming lot or site, shall also be
				subject to the following requirements:
1. Whenever possible, unsignalized driveways on divided State
				highways for major traffic generators involving left-turns to a lot or site
				from a State highway and egress from a lot or site to a State highway should be
				located at existing median breaks. In such cases, the driveway should be lined
				up with the median break or be located 330 feet from the median opening. For
				new median openings, traffic signal spacing requirements must be met. (See
				N.J.A.C. 16:47 Appendix G.)
2. Whenever possible, on undivided State highways, access on
				both sides of the road shall be aligned. Where this is not possible, it is
				desirable to have the centerlines of driveways offset at least 200 feet.
3. No driveway shall be located along an acceleration,
				deceleration, or exclusive right-turn or left-turn lane where the lane is at
				its full width. This prohibition does not apply:
i. Along two-way left-turn lanes;
ii. To a right-turn-in only driveway from a divided State
				highway within the limits of a left-turn lane;
iii. To driveways on the opposite side of a State highway
				within the limits of a right-turn lane;
iv. To access to a lot zoned or used for a single family
				residential unit;
v. To the portion of a deceleration lane for a reverse loop
				jughandle that precedes a street intersection; or
vi. Along collector-distributor lanes.
4. No driveway shall be located along a ramp or a
				jughandle.
5. No new driveway shall be located within the inscribed circle
				area of a roundabout unless it is designed as an approach to the roundabout. No
				new driveway shall be located opposite the splitter island of a roundabout or
				within 50 feet of the end of the splitter island of a roundabout. Existing
				driveways located within the inscribed circle area of a proposed roundabout or
				within 50 feet of the end of the splitter island of a proposed roundabout will
				be evaluated on a case-by-case basis for safety and operational
				efficiency.
D-3 Location of new interchanges
a. A new interchange on a State highway segment shall be at
				least one mile from the nearest interchange on an urban State highway or at
				least two miles from the nearest interchange on a rural State highway.
				Designations for urban and rural State highways shall be found by using
				N.J.A.C. 16:47 Appendices A and B-2. The distance between interchanges shall be
				measured from the center point of each interchange which is defined as the
				midpoint of the extremities of the ramp system for the interchange.
b. A new interchange shall be separated from a signalized
				intersection by at least the minimum traffic signal spacing requirements found
				at N.J.A.C. 16:47 Appendix G. The distance shall be measured from the center
				point of the interchange to the center point of the intersection.
c. A new interchange may be permitted when at least one of the
				following conditions is met:
1. Two divided multi-lane accessible principal arterials
				cross;
2. If a traffic signal is installed at the location proposed
				for the interchange and the green time available would be less than 50 percent
				for accessible principal arterials or less than 40 percent for minor
				arterials;
3. A new at-grade signalized intersection at the same location
				would not provide LOS C or better for the through movement of the State highway
				during any peak period when the closest signalized intersections on the State
				highway on either side of the location are currently operating at LOS C or
				better for the through movement on the State highway;
4. An existing at-grade signalized intersection at the proposed
				location operates at overall LOS F during any peak period and there is no
				reasonable improvement that can be made to provide sufficient capacity;
5. The minimum through band widths for State highway traffic
				signal progression, as described in NJ.A.C. 16:47 Appendix G, cannot be
				maintained; or
6. A proposed major traffic generator will be served by an
				existing street intersection and it would not be feasible to provide effective
				traffic signal progression along the State highway for both the through traffic
				and the traffic which would be generated by the development.
d. Interchanges proposed to serve major traffic generators may
				be permitted only if a regional benefit to traffic movements can be
				demonstrated, and at least one of the following three conditions is met:
1. The major traffic generator is located along a State highway
				where left-turns or access directly onto the State highway are either
				prohibited by this chapter or would otherwise be undesirable as determined by
				the Department;
2. The traffic flows entering or leaving the traffic generator
				would reduce the highway green time per cycle for any traffic signal which
				would serve the traffic generator to less than 50 percent for accessible
				principal arterials and less than 40 percent for minor arterials; or
3. The location that would otherwise be signalized does not
				meet the traffic signal spacing criteria set forth in NJ.A.C. 16:47 Appendix G
				and signalization of the driveway or street would impede the progressive flow
				along the State highway.
