Section 16:47-4.26 - Signalized intersection standards
Universal Citation: NJ Admin Code 16:47-4.26
Current through Register Vol. 56, No. 24, December 18, 2024
(a) Signalized intersection standards for determining fair-share contributions for State highway approaches are as follows:
1.
The general standards listed in
N.J.A.C.
16:47-4.2 4 apply. LOS will be measured by
stopped delay per vehicle per Table 9-1 of the "1994 Highway Capacity Manual,"
Special Report 209, or superseding issue.
2. For all movements at:
i. Study locations, applicable to an urban
lot, on all approaches operating at LOS A, B, C, D, or E, under the no-build
condition; deterioration by 25 percent of the difference between the no-build
condition to the bottom of LOS E (60 seconds) will be allowed. If a traffic
movement or a lane group on all approaches operates under the no-build
condition at LOS F, no deterioration will be allowed. Exceptions may be made to
the delay standards for left turn lanes and jughandles, but the left turns and
jughandles must not back up onto the through lanes;
ii. Study locations, applicable to a rural
lot, on all approaches operating at LOS A, B, C, or D under the no-build
condition, deterioration by 25 percent of the difference between the no-build
condition to the bottom of LOS D (40 seconds) will be allowed. If a traffic
movement or a lane group on all approaches operates under the no-build
condition at LOS E or F, no deterioration will be allowed. Exceptions may be
made to the delay standards for left turn lanes and jughandles, but the left
turns and jughandles must not back up onto the through lanes.
3. Delay will be used to compare
build and no-build conditions for values of V/C ratios up to the lesser of 1.2
or the reciprocal of the peak-hour factor (1/PHF). V/C ratios will be used to
compare build and no-build conditions when the no-build V/C ratio exceeds the
lesser of 1.2 or the reciprocal of the peak-hour factor (1/PHF).
4. If any no-build movement on any approach:
i. For study locations, applicable to an
urban lot operating at a V/C ratio greater than 1.2, then the build conditions
shall not increase the V/C ratio on that movement.
ii. For study locations, applicable to a
rural lot operating at a LOS E or F (delay equal to or greater than 40
seconds), then the build conditions shall not increase the delay on that
movement. Also, a no-build V/C ratio exceeding 1.2 shall not be
increased.
5. Comments
on the interaction of conflicting movements at adjacent driveways and roadways
are required.
6. If there is a
traffic signal within 2,640 feet (805 meters) of the lot, an arterial analysis
may be required.
(b) If a new approach is added to an existing signalized intersection, the new approach shall operate at LOS C based on the build year traffic volumes and in accordance with (a) above. All proposed new signalized intersections shall operate, at minimum, at LOS C for all approaches.
