New Jersey Administrative Code › Title 16 - TRANSPORTATION › Chapter 47 - STATE HIGHWAY ACCESS MANAGEMENT CODE › Subchapter 4 - ACCESS CLASSIFICATIONS AND LEVELS › Section 16:47-4.36 - Traffic impact study area

Current through Register Vol. 56, No. 14, July 15, 2024
(a) Traffic impact
				study locations shall be established as follows:
1. The half of each trip furthest from the
				site shall be eliminated. The applicant's responsibility for all trips between
				the lot and another destination ceases at the midpoint of each trip. This
				determination shall be made based on a trip table which identifies origins and
				destinations.
2. Those locations
				exceeding both 100 new half-trips during the critical peak hour(s), determined
				in accordance with
				16:47-4.3 0(d)1i and 10 percent of
				the anticipated daily site traffic shall be analyzed. Intersections,
				uninterrupted flow sections, weaving sections, merges, and diverges are
				examples of locations which shall be analyzed.
3. When determining whether the new 100 peak
				hour half trips and the 10 percent of the anticipated daily site traffic in
				accordance with (a)2 above have been met, the following criteria shall be
				utilized:
i. For signalized intersections:
(1) The number of existing separate traffic
				signal phases shall be determined;
(2) For each signal phase, the number of new
				site-generated peak hour half trips assigned to each traffic movement on each
				approach shall be determined. When a traffic movement is allotted green time in
				two or more signal phases, the traffic volume based on the percentage of the
				available green time for traffic movement shall be proportional;
(3) For each signal phase, the site-generated
				traffic volumes that conflict shall be added together. In the event that the
				signal phasing and geometry preclude traffic conflict, the highest
				site-generated half trips traffic volume for any given signal phase by
				direction shall be considered the traffic volume in conflict. The higher
				traffic volume in conflict under each signal phase shall be taken;
(4) The traffic volumes for all traffic
				signal phases obtained in (a)3i(3) above shall be added. This is the total
				number of new site-generated peak hour vehicle trip impacts for determining
				study area locations at the signalized intersection;
(5) If the total number of new site-generated
				peak hour half trips is greater than or equal to 100, then this location may be
				a study area location and the above four steps shall be repeated for
				anticipated daily site-generated traffic. If the number is less than 100, then
				the signalized intersection is not a study area location; and
(6) If the total number of new site-generated
				daily half trips at the location is greater than or equal to 10 percent of the
				new site-generated daily trips, then this location is a study area location. If
				the number is less than 10 percent, then the signalized intersection is not a
				study area location.
ii.
				For divided highways, at ramps and ramp junctions, unsignalized intersections,
				uninterrupted flow sections, weaving sections, merges and diverges, the
				assignment of site-generated traffic volumes within the half trip length shall
				be determined as follows:
(1) Turning site
				trips are defined as that component of the site-generated traffic volume,
				within the half trip length, which will turn on to or off of the highway within
				1,500 feet (457.5 meters) of a highway access point. Through site trips are
				defined as that component of the site traffic volume, within the half trip
				length, which will not turn on to or off of the highway within 1,500 feet
				(457.5 meters) of a highway access point;
(2) Through site trips shall be uniformly
				distributed among the through lanes on the highway. Assign turning site trips
				to the right-most through lane;
(3)
				If the total number of turning site trips plus through site trips in the
				right-most through lane during the peak hour is greater than or equal to 100,
				then this location may be a study area location and this test shall be repeated
				for anticipated daily site-generated traffic. If the number during the peak
				hour is less than 100, then the location is not a study area location;
				and
(4) If the total number of
				turning site-generated daily trips is greater than or equal to 10 percent of
				the daily trips, then this location is a study area location. If the number is
				less than 10 percent, then the location is not a study area location.
iii. For all other locations, the
				general standards in accordance with (a)1 and 2 above shall be
				applied.
4. Driveways to
				lots except for the applicant's driveways shall not be considered study area
				locations. However, signalized driveways shall be addressed when progression is
				analyzed pursuant to
				16:47-3.4(b)  2,
				3.4(c)2 and 4.30(c)6v.
