Multi-way stop control can be useful as a safety measure at intersections if
certain traffic conditions exist. Safety concerns associated with multi-way
stops include pedestrians, bicyclists, and all road users expecting other road
users to stop. Multi-way stop control is used where the volume of traffic on
the intersecting roads is approximately equal.
02 The restrictions on the use of STOP signs
described in Section 2B.04 also apply to multi-way stop applications.
Guidance:
03 The decision to install multi-way stop
control should be based on an engineering study.
04 The following criteria should be
considered in the engineering study for a multi-way STOP sign installation:
A. Where traffic control signals are
justified, the multi-way stop is an interim measure that can be installed
quickly to control traffic while arrangements are being made for the
installation of the traffic control signal.
B. Five or more reported crashes in a
12-month period that are susceptible to correction by a multi-way stop
installation. Such crashes include right-turn and left-turn collisions as well
as right-angle collisions.
C.
Minimum volumes:
1. The vehicular volume
entering the intersection from the major street approaches (total of both
approaches) averages at least 300 vehicles per hour for any 8 hours of an
average day; and
2. The combined
vehicular, pedestrian, and bicycle volume entering the intersection from the
minor street approaches (total of both approaches) averages at least 200 units
per hour for the same 8 hours, with an average delay to minor-street vehicular
traffic of at least 30 seconds per vehicle during the highest hour;
but
3. If the 85th-percentile
approach speed of the major-street traffic exceeds 40 mph, the minimum
vehicular volume warrants are 70 percent of the values provided in Items 1 and
2.
D. Where no single
criterion is satisfied, but where Criteria B, C.1, and C.2 are all satisfied to
80 percent of the minimum values. Criterion C.3 is excluded from this
condition.
Option:
05 Other criteria that may be considered in
an engineering study include:
A. The need to
control left-turn conflicts;
B. The
need to control vehicle/pedestrian conflicts near locations that generate high
pedestrian volumes;
C. Locations
where a road user, after stopping, cannot see conflicting traffic and is not
able to negotiate the intersection unless conflicting cross traffic is also
required to stop; and
D. An
intersection of two residential neighborhood collector (through) streets of
similar design and operating characteristics where multi-way stop control would
improve traffic operational characteristics of the
intersection.
