CITY OF CARLSBAD
TRAFFIC SAFETY COMMISSION
REPORT OF: October 6, 1986
(This item was continued from the August
Traffic Safety Commission meeting.)
ITEM NO.D-4
4, 1986 --
LOCATION: Intersection of Park Drive and Kelly Drive.
INITIATED BY: Susan Haupert, 4904 Park Drive, Carlsbad, CA
PROBLEM AS STATED BY REQUESTOR:
Additional stop signs are needed at this intersection.
DATA:
Kelly Drive intersects Park Drive creating a "T'' intersec-
tion. A stop sign is located on Kelly Drive. On the
of this intersection is Kelly
~chool immediately north of the
Park Drive curves northeasterly
immediate northwest corner
Park, with Kelly Elementary
park. East of Kelly Drive,
to a residential area.
During the school year, children cross Kelly Drive with the
assistance of school crossing guards (see attached letter
from Kent Sears). To improve sight distance, hedges along
Park Drive east of Kelly Drive were trimmed. Advanced
warning signs have been installed on Park Drive advising
motorists of the school crossing. There have been no
reported accidents in the past eighteen (18) months (see
attached accident diagram). Recent traffic counts are
attached.
The primary function of a stop sign is to assign right-of-way
to crossing streams of pedestrians, bicyclists and motor
vehicles to share the same intersection. Installation of a
stop sign at locations where they are unexpected should
generally be avoided, as the stop sign may lead to an
increase in accidents. The basic criteria (policy) that
establishes the need for stop signs is commonly referred to
as Stop Sign Warrants.

ITEM NO.D-4
Stop Sign Warrants contained in that policy are adopted from
nationally accepted criteria and only those intersections
that meet the minimum warrants should be considered for stop
signs. Any of the following conditions may warrant a multi-
way stop sign installation:
1. Where traffic signals are warranted and the need is
urgent, the four~way stop is an interim measure that can
be installed quickly to control traffic while arrange-
ments are being made for the signal installation.
2. An accident problem, as indicated by five or more
reported accidents, of a type susceptible of correction
by a four-way stop installation in a 12-month period.
Types of accidents susceptible of correction include
right angle and left turn collisions.
3. Minimum volume warrant:
a. The total vehicular volume entering the intersec-
tion from all approaches must average at least 500
vehicles per hour for any eight hours of an average
day, and
b. The combined vehicular and pedestrian volume from
the minor street or highway must average at least
200 units per hour for the same eight hours with an
average delay to minor street vehicular traffic of
at least 30 seconds per vehicle during the maximum
hour.
c. When the 85-percentile approach speed of the major
street traffic exceeds 40 miles per hour, the
minimum vehicular volume warrant is 70 percent of
the above requirements.
CONCLUSION:
None of the warrants for the installation of additional stop
signs at the intersection of Kelly Drive and Park Drive are
met.

tion.

required for Council action if the stop sign is recommended.

SCHOOL PEDESTRIAN SAFETY AT THE INTERSECTION OF PARK DR. AND KELLY DR.
The City Engineering Department was asked to ·1ook at the operation of
TELEPHONE
(619) 438-5541
the intersection of Park Dr. and Kelly Dr. in regard-to school pedestrian
safety. A suggestion was made to create a three way stop. Though I cannot
recommend a three way stop there are measures which can enhance safety for the
students.
Our field investigation found that the hedge along Park east of Kelly restricted
the view drivers had of the activity of the crosswalk area. These hedges will
be removed. We will also be placing advance signing on Park to alert drivers
of the school crosswalk area.
The Student Safety Patrol, which you use at this intersection, is an excellent
way to provide for the safety of students crossing Kelly. When properly trained
I feel it is the best method. After observing your Student Safety Patrol, I
have the following suggestions:
1. The patrol members with paddles should be placed on al I three legs
of the inte'rsection, simulating a three way stop during peak pedes-
trian activity.
2. These same students should stand out of the travelled lane. They
should stand in the parking lane or in the shoulder area.
3. Students should be crossed only after a reasonably large group has
accumulated.
4. If vehicles are approaching, they shoul.d be allowed to stop completely
before crossing the students. Not only does this ensure the vehicle
stops, but it provides a buffer between the students and any other
approaching traffic.
With these changes, I believe we
for the safety of the students.
