SPEED ZONING SURVEY
VARIOUS CITY STREETS IN ARCADIA
NOVEMBER 1988
The California Vehicle Code in Section 40802(b) defines a speed trap as a
section of highway with a prima facie speed limit not justified by an
engineering and traffic survey conducted within the last five years and where
enforcement involves the use of radar or other electronic devices used to
. measure the speed of moving objects. Section 40803 declares that evidence
obtained from the use of a speed trap is inadmissible in court in prosecuting
under the Code.
The current Engineering and Traffic Study which was adopted by the City of
Arcadia in 1984 will expire in January 1989. This proposed Speed Zoning
Survey establishes recommended speed limits on portions of 24 City streets and
is required for continued radar enforcement.
The traffic and engineering survey referred to above is. defined in Section 627
of the Vehicle Code as a survey of highway and traffic conditions in
accordance with methods determined by the Department of Transportation
(Ca1trans) for use by State and local authorities. The survey must include:
a) Prevailing speeds as determined by traffic engineering measurements
b) Accident records
c) Highway, traffic and roadside conditions not readily apparent to the
driver.
Caltrans' Method for Engineering and Traffic Survey on City Arterials and
Co II ector Road s
The Ca1trans' method bases speed zoning on the premise that a reasonable speed
limit is one that conforms to the actual behavior of the majority of motorists
and that by measuring speeds, one will be able to select a limit that is both
reasonable and effective.
Their manua 1 states, "Exper ience has shown that speed 1 imits shou 1 d be
estab 1 i shed at or be 1 ow the 85 percent ile speed, wh ich is the speed at or
below which 85% of the traffic is moving." The speed chosen for speed zoning
should be in five mile per hour increments and should normally be selected at
a value immediately below the 85 percentile speed unless it is within 1-1/2
miles per hour of the next higher increment,
1898
SPEED ZONING SURVEY
NOVEMBER 1988
As a check on the validity of the proposed speed limit, an analysis should be
made of the two-year accident record for the roadways under consideration. If
this record shows an abnormally high percentage of accidents normally
associated with excessive speeds, the proposed limit should be reduced.
This is as much a judgment situation as is the interpretation of causes of
accidents. However, if a driver cannot stop in time to avoid a collision, he
is probably traveling faster than reasonable at that particular time under the
conditions prevailing at that time.
Regarding the third element of the study, Section 22358.5 of the Code states,
"It is the intent of the Legislature that physical conditions such as width,
curvature, grade and surface conditions, or any other condition readily
apparent to a driver, in the absence of other factors, would not require
special downward speed zoning, as the basic rule of Section 22350 is
sufficient regulation as to ~uch conditions."
Obviously, in most surveys, the speed zoning is established on the basis of
prevailing speeds. While not generally palatable to local officials, this
method does acknowledge the fact that drivers set the pace (regardless of
posted speed limits) and this is accepted as reasonable under normal
conditions. Further, this acknowledgment permits a consistent and defensible
enforcement effort.-
The establishment of a speed limit below the critical speed (85th percentile)
should be done with great care as this may make violators of a
disproportionate number of the reasonable majority of drivers.
The Survey
Procedures as out 1 ined in the Ca ltrans Traffic Manual and briefly described
above were followed by both the Pol ice Department in conducting the radar
speed measurements as well as by the Engineering Division in reviewing
accident reports and field checking for unusual conditions. The data thus
obtained formed the basis of this report and recommendations.
Prevailing Speeds
All sampled speed checks were conducted during off-peak hours and contained
100 vehicles per location. The speeds shown are the 85th percentile speeds
and the pace is that 10 mile per hour increment containing the largest number
of vehicles.

In order to evaluate severity of Arcadia midblock accident history for streets
included in this study, two comparisons were made.
1. A ratio of injury accidents to total accidents in the City versus a
similar ratio for the study area for the years of 1987 and 1988. The
information was obtained from California Statewide Integrated Traffic
Records System (SWITRSl report for Arcadia. As shown on the tabulation
for the two year accident history, the City-wide accidents totaled 1,748
of which 805 were injury accidents. The City-wide ratio was 805/1,748, or
0.46. The study area ratio was an average of 0.50 which was slightly
greater for the 34 segments of roadway shown on the tabulation than for
the entire City.
Any street or portion thereof having a ratio greater than 0.50 (which is
the greater of the two ratios shown above) has an accident history of
greater than average severity and therefore it must be assumed that
speeding was a factor in said accident.

1898
SPEED ZONING SURVEY
NOVEMBER 1988
2. A second comparison was made between study area accident rates per million
vehicle miles (A/MVM) with similar statistics developed by the Los Angeles
County Road Department Study of 1982-83 wherein 81 miles of highway had an
acc i dent rate of 1. 55 A/MVM. Arcad i a's study area covered 43 miles with
an accident rate of 1.28 A/MVM plus a rate of accidents involving personal
injury of 0.61 IA/MVM. Thus, the total accident rate was somewhat greater
in the County study (1.55 County to 1.28 City), and using the more
conservative rates, the presumption that speeding was a factor on any
street having an accident rate greater than 1.28 and an injury accident
rate greater than 0.61 must be maintained.
Speed Limit Reduction
The speed limit justified by prevailing speed studies could be reduced by five
miles per hour on any street or portion thereof shown in the tabulation to
equal or exceed at least two of the following:
1. Ratio of injury accidents to total accidents exceeding 0.50.
2. Accident rate per million vehicle miles per year exceeding 1.28.
3. Injury accident rate per million vehicle miles per year exceeding 0.61.
Conditions Not Readily Apparent to the Driver
With one exception, no physical conditions involving width, curvature grades
or surface conditions are existing which are not readily apparent to the
driver. . Other factors such as dips, shrubbery, obscuring driveways or
intersecti6ns, lane changes, midblock crosswalks, etc., are presently signed
for advance warning to the motorist or are obviously present, and downward
speed zoning on the basis of this aspect of the Engineering Study is not
justified.
One exception is Baldwin Avenue between Foothill Boulevard and Huntington
Drive, a distance of 1.2 miles which is currently posted at 35 mph.
Baldwin Avenue is a divided four lane roadway providing ingress and egress
to the Foothi 11 Freeway, L. A. State and County Arboretum, Santa Anita
Race Track, Santa Anita Fashion Park and four local roadways. Traffic
volumes on Baldwin Avenue have increased approximately 15% in the past
five years and current ly averages 28,460 vehic les per day increas ing to
over 30,000 vehicles per day during the Santa Anita racing meet and the
peak commercial use at Santa Anita Fashion Park.
Ba ldwi n Avenue from Stanford Drive souther ly a distance of approximate ly
3,000 feet presents the motoring public with a series of horizontal curves
and a north to south downgrade, both constituting a potential hazard to
the unwary.
An analysis of the SWITRS report indicates "Unsafe Speed" or "Following
Too Close" as the primary collision factor in 15 of the 35 reported
midblock accidents.

1898
SPEED ZONING SURVEY
NOVEMBER 1988
In view of the above discussion where traffic volume, roadway alignment
and an assumption that unsafe speed contribute to a significant number of
accidents, it is recommended that consideration be given to retaining the
posted speed of 35 mph.

In the City Council deliberations of the recommendations, please consider the
following:
1. The recommended zones will not attract a change in driver behavior. They
will generate a favorable change in driver attitude.
2. As our studies indicate, the recommendations contained in this report do
not propose an increase in operating speeds, but an adjustment of the law
to which the motorist is subjected, to more closely reflect existing safe
levels.
3. The enforcement effort will be properly directed through realistic zoning,
and the judicial acceptance of these efforts should be well received. The
average daily traffic count on the streets included in the study is 13,854
vehicles. If 15% (or 2,078 vehicles per day) are exceeding a reasonable
and prudent speed on each of the 34 streets or portions thereof included
in the study, there are 70,652 motorists per day who would be in violation
of the proposed limits.
