TRAFFIC SAFETY C<MtISSION
COMMISSION REPORT OF: February 1, 1988 ITEM NO. 6A
LOCATION: Intersection of Elm Avenue and Chatham Road
INITIATED BY: Cheryl Ernst, Principal, Hope Elementary School, 3010 Tamarack
Avenue, Carlsbad, California 92008
BACKGROUND:
DATA:
Ms. Ernst, in her letter of October 5, 1987 requested that a four-way STOP
be established at the Elm Avenue/Chatham Road intersection. At this time,
STOP signs control Chatham Road, however no controls have been placed on
Elm Avenue.
This matter was discussed at the December 7, 1987 meeting of the Traffic
Safety Commission. Only three (3) of five (5) Commissioners were present
at the meeting. After hearing the staff report and receiving input from
the Principal of Hope Elementary School, including several parents, the
Commission voted 2-1 to recommend to the City Council that a four-way STOP
intersection be established.
Subsequently, at the January 1988 Traffic Safety Commission meeting the
City Engineer requested recons i de ration of the recommendation before a
full Commission. The Commission voted 3-1, with one member absent, to
reconsider this matter at the February 1, 1988 Traffic Safety Commission
meeting. School officials of Hope Elementary were notified of this action.
A memo received from the City of Carlsbad Risk Manager addressing his
concerns about the Elm Avenue/Chatham Road intersection is attached. The
previous memo to the Commission from the City Engineer is also included.
Elm Avenue is designated as a Secondary Arterial on the Circulation
Element of the General Plan. Chatham Road is a residential street
intersecting Elm Avenue and provides access to a portion of the Calavera
Hills area. In the future, a traffic signal will be installed at the Elm
Avenue/Tamarack Avenue intersection. However, at this time the Elm/
Tamarack intersection is a four-way STOP controlled intersection.
A traffic count was obtained at the Elm/Chatham intersection to determine
if a 4-way STOP is warranted. Vehicle approach volumes and the total
entering volume is shown on Exhibit 1. Warrants for STOP sign installations
contained in the CALTRANS Traffic Manual are also attached. At this
location, the 85th percentile speed on Elm Avenue is 41 miles per hour,
TRAFFIC SAFETY CotfilISSION
COMMISSION REPORT OF: February 1, 1988

ITEM NO. 6A
therefor the minimum vehicular volume is 70% of the stated volume warrant.
It can be observed from Exhibit 1 that there are only four (4) hours of an
average day when the total vehicular volume entering the intersection is
70% of 500 vehicles per hour (350 vehicles) or more.
In the past 12 months, there has been one (1) reported accident at the Elm
Avenue/Chatham Road intersection. Pedestrian volumes are very low except
in the morning and afternoon when students are going to and from school. A
recent count of students crossing Elm Avenue at Chatham Road in the
morning found 10 pedestrians crossing at the intersection and 44 crossing
near the intersection. In the afternoon a total of 22 pedestrians crossed
at the intersection and 43 crossed Elm Avenue near the Chatham Road
intersect io n. At the intersection of Elm Avenue and Tamarack Avenue, a
total of 36 pedestrians crossed Elm Avenue in the morning and 29 crossed
in the afternoon. Field sheets indicating the turning volumes and
pedestrian volumes at each intersection are attached.
CALTRANS warrants for Adult Crossing Guards contained in the Traffic
Manual are attached. From the latest pedestrian counts, an Adult Crossing
Guard is not warranted at the Elm Avenue/Tamarack Avenue intersection but
would meet pedestrian volume warrants if students crossing at Chatham Road
crossed at Tamarack Avenue. Minimum vehicular volume warrants are not met
at the Tamarack Avenue/Elm Avenue intersection during the one hour period
before and after school as indicated on Table A.
The Traffic Safety Coordinating Committee does not recommend placing
Chatham Road on the Suggested Route to School due to the number of
conflict points (intersections) which the pedestrians must cross when
walking on Chatham Road between Elm Avenue and Tamarack Avenue and the
fact that students would have to cross Elm Avenue at an uncontrolled
intersection. This intersection meets the requirements of a rural
intersection for an uncontrolled crossing. The vehicle volume warrant
would be 300 vehicles during each of any two hours in which 30 or more
school pedestrians cross daily while going to or from school. As can be
observed on Table A, minimum vehicle volume warrants are met and if all
students crossed at the intersection the minimum pedestrian volume would
al so be met.
STOP sign warrants for the Elm Avenue/Chatham Road intersection are not
met and STOP signs should not be installed. If school officials and
parents are not requiring students to follow the Suggested Route to
School, pedestrians will continue to cross Elm Avenue at and near Chatham
Road. Moving the existing Adult Crossing Guard from the Tamarack Avenue
intersection to the Chatham Road intersection would aid school pedestrians
in crossing Elm Avenue.

ITEM NO. 6A
Based upon the low entering volumes, very low number of ace i dents and
adequate sight distance at the subject intersection, the Traffic Safety
Coordinating Committee does not recommend creating a four-way STOP
intersection by installing STOP signs on Elm Avenue at Chatham Road. The
following options are available and recommended by the Traffic Safety
Coordinating Committee:
1. Request that school officials of Hope Elementary work with the
parents and not a 11 ow students to cross Elm Avenue at Chatham
Road.
2. Request that school officials (and parents) monitor the Chatham
Road/Tamarack Avenue intersection and not allow students to walk
up Chatham Road on the way home, but direct the students
southerly on Tamarack Avenue to the intersection of Elm Avenue/
Tamarack Avenue. Likewise, they would monitor the Chatham
Road/Elm Avenue intersection and direct students easterly on Elm
Avenue to the Adult Crossing Guard stationed at Elm Avenue/Tamarack
Avenue.
3. Have Officer Friendly and a Traffic Division Officer of the
Carlsbad Police Department address the student body in an
assembly to discuss safe walking and bicycle riding to and from
school. This meeting to be arranged by the Hope Elementary School
Principal.
The following options are NOT recommended by the Traffic Safety Coordinating
Committee:
1. Move the Adult Crossing Guard from Tamarack Avenue to Chatham Road.
2. Hire an additional Adult Crossing Guard for Hope Elementary
School students and place that individual at Chatham Road. A
guard would therefore be at Tamarack Avenue and Chatham Road
where each roads intersects Elm Avenue.
3. Install STOP signs on Elm Avenue at Chatham Road.

Dear Mr. Shirey:
"Excellence In Education"
.. __,
As you know, we have had several conversations regarding the safety of the
students to and f rom Hope Elementary School this year. Many of my parents are
still very concerned about certain intersections and other safety hazards. I
have formed a committee of the concerned parents to study the issues and
prioritize them and seek alternatives.
The purpose of t his letter is to inform you that the parent representatives
and I would like very much to have an opportunity to speak with the Traffic
Commission regard ing the intersection of Chatham and Elm Avenue. I have re-
commended to parents through my newsletters, as you have suggested, that students
walk down to the Tamarack and Elm crossing for the safe route to school; however,
many youngsters and their parents are utilizing the Chatham and Elm i ntersection
to cross instead. There have been several near misses with youngsters crossing
in that area, and there have been cars which have had problems entering onto
Elm Avenue from Chatham because of the difficulty. Our parents from the Safety
Committee are recommending that a 4-way stop be placed at that intersection to
enable youngsters to cross in a safer fashion. Our committee is also intending
to recommend that an unmarked car be placed at that intersection to observe the
patterns of beh av ior. It is my understanding that you left a message in my office
that you had be en conducting this type of observation and we appreciate that very
much. The paren t s would still, however, like an opportunity to speak with the
Traffic Conmiss ion further on this issue.
I appreciate the time and considerations you have given in our new school 1 s
opening and the safety of our students. I look forward to hearing from you re-
garding their opportunity to attend one of the Traffic Commission meetings.

TO: CITY ENGINEER
FROM: Risk Manager
REQUEST FOR A 4-WAY STOP AT THE INTERSECTION OF ELM AVENUE
AND CHATHAM ROAD
The proposal for a 4-way stop sign at the intersection of Elm and Chatham has
been reviewed at length by the members of the Traffic Safety Coordinating
Committee both as a group and in their individual capacities as a part of their
work responsibilities.
As a result of my review of the situation, it is recommended that the request
for a 4-way stop be denied for the following reasons.
1. There is a sight/distance problem for eastbound traffic on Elm Avenue.
The proposed intersection would appear at the end of a short curve.
Vehicles backed up from the intersection would pose a hazard to
approaching vehicles that had not yet observed the intersection stop
signs because of the curvature of the street.
2. The north side of the proposed intersection is even more obscured because
of the wooden barricade and the trees. Pedestrians walking south,
especially small children, would be hidden from the view of eastbound
traffic. This would create a false sense of safety which could have
tragic results.
3. The Cal Trans Traffic Manual deals with this specific problem at
Section 10-02. 3. It states that 11 ••• school routes should be planned to
take advantage of the protection afforded by existing traffic controls. 11
A review of the factors to be considered for determining the routes makes
it clear that the existing recommended route, even though minimally
longer, is the best solution to the safety problem.
4. The hazards cited would increase the risk of an accident occurring and,
as a result, would expose the City to an additional liability problem.
It would be extremely tragic to give small children a false sense of security or
safety by creating a dangerous intersection and then having one or more of them
injured or killed as the result of an accident.
The issue would appear to be one of convenience vs. safety and, considering
the potential hazards, the only proper decision would be the one that provides
the greatest level of safety for the children using the route.
If you have any questions, or if I can be of any additional assistance, please
feel free to contact me.

TO: TRAFFIC SAFETY COMMISSION
FROM:· CITY ENGINEER
INTERSECTION OF ELM AVENUE AND CHATHAM ROAD
At the Commission's December 7 meeting, the subject intersection was
considered and recommended for the installation of four-way stops.
At that meeting, only three members were present, with two voting
the recommendation.
It is my strong opinion, and that of the Traffic Safety Coordinating
Committee, that a four-way stop at this intersection is not warranted,
and w_ill severely hamper the efficient flow of traffic.
Although traffic along Elm Avenue is light at the current time, that
situation will be changed in the near future. As traffic increases on
Elm Avenue, signals will be required at Elm and Tamarack Avenues.
At that time, stop signs at Elm and Chatham will become a significant
hindrance to the flow of traffic. This significant flow restriction will
increase hazards throughout the day, simply to accommodate student
crossings during two short periods of the day.
I feel that overall safety and efficiency is best served by directing
current and future children to the controlled intersection of Elm and
Tamarack Avenues, retaining the current controls at Chatham and Elm.
To accomplish this, I would request the Commission to reconsider its
previous actions before the full Commission at its February meeting.
Respectfully submitted,

POLICY
Stop Signs and Yield Signs
• Stop Signs
The STOP sign (R1) shall be used where traffic
is required to stop except at signalized Intersections.
The STOP sign shall be an octagon with white mes-
sage and border on a red background. The standard
size shall be 30 x 30 Inches. Where greater emphasis
or visibility Is required, a larger size is recommended.
On local streets and secondary roads with low ap-
proach speeds and low volume, a 24 x 24 inch size
may be used.
At a multiway stop intersection, a supplemental plate
(R1 ·3 or R1 -4) should be mounted just below each
STOP sign.
The numeral on the supplementary plate shall corres-
pond to the number of approach legs, or the legend
ALL-WAY (R1·4) may be used. The plate shall have
white letters on a red background.
A red flashing beacon or beacons may be used in
conjunction with a STOP sign. See Section 9-08
(Flashng Beacons).
Secondary messages shall not be used on STOP sign
faces.
• Warrants for STOP Signs
Because the STOP sign causes a substantial incon-
venience to motorists, it should be used only where
warranted. A STOP sign may be warranted at an inter-
section where one or more of the following con-
ditions exist:
1. On the less important road at its intersection with
a main road where application of the normal right
of way rule is unduly hazardous as evidenced by
accidents susceptible to correction by STOP
signs.
2. On a county road or city street at its intersection
with a state highway.
3. At the intersection of two main highways. The
highway traffic to be stopped depends on ap-
proach speeds, volumes, and turning movements.
4. On a street entering a legally established through
highway or street.
5. On a minor street where the safe approach speed
to the intersection is less than 10 miles per hour.
6. At an unslgnalized intersection in a signal-
ized area.
7. At other intersections where a combination of high
speed, restricted view, and accident record indi·
cates a need for control by the STOP sign.
4-38
3-1987
SIGNS Traffic Manual
POLICY
A STOP sign Is not a "cure-air' and Is not a substitute
for other traffic control devices. Many times the need
for a STOP sign can be eliminated If the sight distance
is Increased by remo"'ng the obstructions.
STOP signs shall not be erected at any entrance to an
intersection when such entrance Is controlled by an
official traffic control signal, nor at any railroad grade
crossing which is controlled by automatic signals,
gates, or other train-actuated control devices except
as provided In eve 21355, Stop Signs. The conflicting
commands of two types of control devices are con-
fusing. If traffic is required to stop when the operation
of the stop-and-go signals is not warranted, the signals
should be put on flashing operation with the red flashing
light facing the traffic that must stop.
Where two main highways Intersect, the STOP sign or
signs should normally be posted on the minor street to
stop the lesser flow of traffic. Traffic engineering studies,
however, may justify a decision to Install a STOP sign or
signs on the major street, as at a three-way intersection
where safety considerations may justify stopping the
greater flow of traffic to permit a left-turning movement.
STOP signs should not be Installed lndlscrlmlnately at
all unprotected railroad crossings. The allowance of
STOP signs at all such crossings would eventually breed
contempt for both law enforcement, and obedience to
the sign's command to stop. STOP signs may only be
used at selected ralVhlghway grade crossings after
their need has been determined by a traffic engineering
study. Such study should consider approach speeds,
sight distance restrictions, volumes, accident records,
etc. This application of STOP signs should be an Interim
use period during which plans for lights, gates or other
means of control are being prepared.
Portable or part-time STOP signs shall not be used except
for emergency purposes. Also, STOP signs should not be
used for speed control.
e Multlway STOP signs
The "Multlway Stop" installation may be useful at some
locations. It should ordinarily be used only where
the volume of traffic on the intersecting roads Is approx-
imately equal. A traffic control signal Is more satisfactory
for an Intersection with a heavy volume of traffic.
Traffic Manual
R1-2
V
Standard 38"
SIGNS
POLICY
4-39
3-1987
Any of the following conditions may warrant a multi-
way STOP sign Installation:
1. Where traffic signals are warranted and urgently
needed, the multlway stop may be an Interim
measure that can be installed quickly to control
traffic while arrangements are being made for
the signal Installations.
2. An accident problem, as indicated by five or more
reported accidents within a 12 month period of
a type susceptible to correction by a multlway
stop Installation. Such accidents Include right·
and left-turn collisions as well as right-angle
collisions.
3. Minimum traffic volumes
(a) The total vehicular volume entering the Inter-
section from all approaches must average at
least 500 vehicles per hour for any 8 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 8 hours, with an average delay to minor
street vehicular traffic of at least 30 seconds
per vehicle during the maximum hour, but
(c) When the 85-percentlle approach speed of
the major street traffic exceeds 40 miles per
hour, the minimum vehicular volume warrant
Is 70 percent of the above requirements.
e Yield Signs
The YIELD sign (R1·2) assigns right of way to traffic
on certain approaches to an intersection. Vehicles
controlled by a YIELD sign need stop only when nec-
essary to avoid Interference with other traffic that
Is given the right of way.
The YIELD sign shall be a downward pointing, equi-
lateral triangle having a red border band and a white
Interior and the word YIELD in red Inside the border
band. The standard size shall be 36 x 36 x 36 inches.
• Warrants for YIELD Signs
The YIELD sign may be warranted:
1. On a minor road at the entrance to an intersection
where it is necessary to assign right of way to the
major road, but where a stop is not necessary
at all times, and where the safe approach speed
on the minor road exceeds 1 O miles per hour.
2. On the entrance ramp to an expressway where an
acceleration lane is not provided.

Traffic Manual SCHOOL AREA PEDESTRIAN SAFETY 10-11
located within 600 feet, School Crossing Traffic Sig-
nals should be considered when either of the follow-
ing conditions are ful fi lled:
1. Urban Areas -500 vehicles and 100 school pede-
strians for each of any two hours (not necessar-
ily consecutive) daily while students are cross-
ing to or from school; or
500 vehicles for each of any two hours daily
while students are crossing to or from school
and a total of 500 school pedestrians during the
entire day.
2. Rural Areas (Use 70 percent of the volumes not-
ed under Urba.n Areas) -350 vehicles and 70
school pedestrians fo r each of any two hours
(not necessarily consecutive) daily while stu-
dents are crossing to or from school; or
350 vehicles for each of any two hours (not
necessarily consecutive) daily while students
are crossing to or fro m school and minimum
total of 350 school pedestrians during the entire
day.
When critical (85 percentile) approach speed ex-
ceeds 40 mph or the approach visibility is less than
the required stopping sight distance, rural warrants
3-1987
should be applied.
The design of School Crossing Traffic Signals shall
conform to Chapter 9 of the State Traffic Manual and
include the foll owing considerations:
l. The signals shall be designed for full-time opera-
tion.
2. Pedestrian signal fac es of the International Sym-
bol type shall be installed at all marked cross-
walks at signalized intersections along the "Sug-

unusual circumstances, such as restricted visi-
bility.
4. If an intersection is signalized under this guide-
line for school pedestrians, the entire intersec-
tion shall be signalized.

Crossing Supervision 10-07
10-07.1 Types of Crossing Supervision
There are two types of school crossing supervision:
l. Adult control of pedestrians and vehicles with
Adult Crossing Guards or police officers.
2. Student control of only pedestrians with School
Safety Patrol.
Recommended practices for the organization, op-
eration and administration of Adult Crossing Guards
and Student Safety Patrols are given in "SCHOOL
CROSSI G GUARD PROGRAMS" and "SCHOOL
SAFETY PATROL PROGRAM " booklets.* Also, see
Sections 10-07.10, 11 herein.
10-07.2 Adult Crossing Guards
Adult Crossing Guards are a supplemental tech-
nique and not a traffic control device. They may be
assigned at designated school crossings to assist ele-
mentary school pedestrians at specified hours when
going to or from school. The following suggested pol-
icy for their assignment applies only to crossings
serving elementary school pedestrians on the "Sug-
gested Route to School".
An Adult Crossing Guard should be considered
when:
l. Special problems exist which make it necessary

Automobile A~sociation (:\:\.-\I.
to assist elementary school pedestrians in cross-
ing the street, such as at an unusually complicat-
ed intersection with fr equent turning move-
ments and high vehicular speeds; or
2. A change in the sc hool crossing location is immi-
nent but prevailing conditions require school
crossing supervision for a limited time and it is
infeasible to install another form of control for
a temporary period.
10-07.3 Warrants for Adult Crossing Guards
Adult Crossing Guards normally are assigned
where official supervision of elementary school
pedestrians is desirable while they cross a public
highway on the "Suggested Route to School", and at
least 40 elementary school pedestrians for each of
any two hours daily use the crossing while going to
or fr om school. Adult crossing guards may be used
under the following conditions:
l. At uncontrolled crossings where there is no al-
ternate controlled crossing within 600 feet; and
a. In urban areas where the vehicular traffic
volume excees 350 during each of any two
hours (not necessarily consecutive) in which
40 or more school pedestrians cross daily
while going to or from school ; or
b. In rural areas where the vehicular traffi c vol-
ume exceeds 300 during each of any two
10-12
J.1987
SCHOOL AREA PEDESTRIAN SAFETY Traffic Manual
hours (not necessarily consecutive) in which
30 or more school pedestrians cross daily
while going to or from school.
Whenever the critical (85 percentile) ap-
proach speed exceeds 40 mph, the guidelines
for rural areas should be applied.
2. At stop sign-controlled crossings:
Where the vehicular traffic volume on undi-
vided highways of four or more lanes exceeds
500 per hour during any pe riod when the school
pedestrians are going to or from school.
3. At traffic signal-controlled crossings:
a. Where the number of vehicular turning
movements through the school crosswalk ex-
ceeds 300 per hour while school ped estrians
are going to or from school; or
b. Where there are circumstances not normally
present at a signalized inter ection, such as
crosswalks more than 80 feet long with no
intermediate refuge, or an abnormally high
proportion of large commercial vehicles.
10-07.4 Legal Authority and Program Funding
for Adult Crossing Guards
Cities and counties may designate local law en-
forcement agencies, the governing board of any
school district or a county superintendent of schools
to recruit and assign adult crossing guards to inter-
sections that meet approved guidelines for adult
supervision.
There are various methods for funding a school
adult crossing guard program. One of these methods
is through the use of fines and forfeitures received
under Section 1463 of the Penal Code. Disposition of
these fines and forfeitures is defined in Sections
42200 and 42201 of the California Vehicle Code. An
example of these dispositions by cities and counties
is as follows:
Disposition by cities (CVC 42200). Fines and
forfeitures received by cities and deposited into a
"Traffic Safety Fund" may be used to pay the
compensation of school crossing guards who are
not regular full-time members of the police de-
partment of the city.
Disposition by county (CVC 42201 ). Fines and
forfeitures received by a county and deposited in
the road fund of the county may be used to pay
the compensation of school crossing guards, and
necessary equipment and administrative costs.
The board of supervisors may adopt standards for
crossing guards and has fin al authority over the
total cost of the crossi ng guard program.
Another avenue of funding school adult crossi ng
guard programs is through the use of the "Crossing
Guard Maintenanc District Act of 1974." This act
defin es how a local agency may form districts within
which property and improvements may be assessed
to pay the costs and expenses of providing school
crossing guards. (Chapter 3.5, Sections 55530-70 of
Part 2, Division 2, Title 5 of the Government Code.)
10-07.5 Choice of Adult Crossing Guards
High standards fo r selection of adult crossing
guards are essential. They must understand children
and in addition should possess the following qualifi-
cations:
1. Average intelligence
2. Good physical condition, including sight and
hearing
3. Mental alertness
4. Neat appearance
5. Good character
6. Dependabl e
7. Sense of responsibility for safety of children.
8. Good verbal communication.
Undoubtedly, the most important quality a cross-
ing guard should possess, however, is the ability to
gain the respect of the children so that they respond
to direction.
10-07.6 Uniform of Adult Crossing Guards
Adult crossing guards should be uniformed so that
motorists and pedestrians can recognize them and
respond to their signals. It is recommended that their
uniforms be distinctively different from those worn
by regular police offic ers.
During periods of twilight or darkness, adult cross-
ing guards should wear either reflectorized material
or re f1 ectorized clothing.
10-07.7 Training Programs for Adult Crossing Guards
Adequate training should b provided in adult
crossing guard r sponsibilities and authority. Experi-
ence indicates that this fun ction can usually be per-
formed effectively by a law enforcement agency re-
sponsible for traffic co ntrol.
Training programs should be d signed to acquaint
newly employed crossing guards with their specific
duties, local traffic regulations, and crossing tech-
niques. Training workshops should also be u ed as a
method of advising experie nced employees of recent
changes in exi ting traffic laws and program proce-
dures. For example, crossing guards should b famil-
iar with the Califo rnia law, which provides that any
person who disregards any traffic signals or direction
given by a nonstudent school crossing guard author-
,,
Traffic Manual SCHOOL AREA PEDESTRIAN SAFETY 10-13
ized by a law enforcement agency, any board of
supervisors of a county or school district shall be gui l-
ty of an infraction and subject to the penalties of
Section 42001 of the California Vehicle Code. (CVC
Section 2815 )
Primarily, adult crossing guards should be instruct-
ed to provide appropriate safety instruction for chil-
dren crossing, watch traffic flow , wait for an appro-
priate gap between vehicles and lead groups of
school children promptly across a street. Under no
circumstances should a crossing guard permit a child
to cross the road alone. Even when there is no traffic
on the road, a crossing guard should be alert to unex-
pected e mergencies and should accompany children
across the street to the curb.
10-07.8 Operating Procedures for Adult
Crossing Guards
Adult crossing guards should not direct traffic in
the usual police regulatory sense. In the control of
traffic, they should pick opportune times to create a
safe gap. At these times, their presence in the road-
way serves as an easily recogni zed indication that
pedestrians are about to use the crosswalk, and that
all traffic must stop. Adult crossing guards may use a
"STOP" paddle (C28A), similar to the one shown in
Section 10-03.8, except that the paddle shall have
"STOP" on both sides and that it shall be reflector-
ized when used during hours of darkness. When all
traffic has stopped, the adult guard all ows the chil-
dren to cross.
10-07.9 School Safety Patrols
School Safety Patrols have a definite role in aiding
school pedestrians at crossings near elementary
schools. This measure is a supplemental technique
rather than a traffic control device as defined in Sec-
tion 440 of the California Vehicle Code.
School Safety Patrols may be used to direct and
control children at crossings near schools where
there is no need to create adequate gaps in traffic.
School Safety Patrols may be used to direct and
control children at signalized intersections where
turning movements are not a problem, and to assist
adult crossing guards in the control of children at
crossing locati ons u ed by large numbers of children.
School Safety Patrols shall not be responsible for
directing vehicular traffic. They do not function as
poli ce.
10-07.10 Warrants for School Safety Patrols
A School Safety Patrol may be established at loca-
ti ons where an existing traffic control device, police
officer or adult crossing guard is in operation, or
where there are adequate crossing gaps in vehicular
flow at an uncontrolled cros ing, and it is desirable to
3-1987
use School Safety Patrols to guide the sc hool pede-
strians. School Safety Patrols should be es tablished
only by agreement between the governing board of
the school district and local traffic law enforcement
agencies.
A School Safety Patrol should be considered when
all of the following conditions are fulfilled:
1. Twenty or more school pedestrians crossing in
each of any two hours (not necessaril y consecu-
tive) daily enroute to or from school; and
2. Critical (85 percentile) approach speed does
not exceed 35 mph; and
3. No more than two traveled lanes in each direc-
tion; and
4. At least one "adequate crossing gap" in traffic
per minute during an average 5-minute period
during the peak school pedestrian hour.
An "adequate crossing gap" is defined as the num-
ber of seconds required for a student to observe the
traffic situation while in a safe location at one side of
a roadway and then to cross the roadway to a point
of safety on the opposite side. The actual walking
time to cross (roadway width in fe et divided by 3.5
fee t per second) must be added to the perception
and reaction time (usually 3 seconds) and a clear-
ance interval of 2 seconds between rows of pedestri-
ans in the platoon / group.
Ga = (W ...,...3.5) +3+2 ( -1)
Whe re Wis the roadway width in feet; N is the num-
ber of rows of pedestrians in a platoon /
group;
A School Safety Patrol shall not be assigned where
inadequate stopping sight distance prevails.
10-07.11 Legal Authority for School Safety Patrols
School Safety Patrols should be authorized by the
local school board. School authorities should be re-
sponsible for organizing, instructing and supervisi ng
patrols with the ass istance of the local police.
The California Education Code [Chapter 8, Article
1, Sections 49300 to 49307 ( 1977)] and the California
Administrative Code [Title 5, Article 3, Sections 570
to 576 (1978) and 632] authorize the development of
School Safety Patrols and outline rules for imple-
menting these programs within the state.
10-07.12 Choice of School Safety Patrols
chool Safety Patrols should be carefully selected .
They should be children fr om the 5th grade or high-
er. Leadership and reliability should be determining
qualities for patrol membership.
