Project Understanding
TJKM's main objective for this swdy is to analyze 87 roadway segmenu throughout the City of
Cupertino (as shown on the figure following this page) and recommend appropriate speed limie
consistent with the laws and practices of the State of California. Since we have recerrcly finalized
our surveys of approximately 61 segmenu In the City of San Leandro, 49 segmene for the City of
EI Cerrito, 45 segmenu in the City of Los Altos, 10 segmenu in the City of Orinda, and 6 segmenu
for the Mountain House Community Service District, we are very familiar with the new California
MUTCD guidelines (or setting speed limits.
For the City of Cupertino, we will conduct an Engineering and Traffic Study in each speed zone
that conforms to Section 627 of the California Vehicle Code and meet the intent of Section 28.13
of the California MUTCD; compile collision data relevant to speed zoning; identify roadway and
traffic conditions that may affect speed zones; prepare a speed survey map; and recommend the
speed limit for adoption by the City Council
With all of the statistics Inherent In the speed survey process, there is a great deal of engineering
judgment required, and to a certain extent, a consistenq process applied during the establishment
of speed limiu. Speed limiu should be realistic and reasonable regardless of the resuks of the
field swdies. Reasonable limie are those at which responsible motorise would drive without
enforcement and without any signage. One cannot rely totally on this assumption, however, as
motorises tend to drive somewhat fatter in residential districu away from their homes than the
residenu of those dlstricu would prefer. In a way, perhaps unconsciously, motorise tend to be
more concerned about speeds near their own homes and less concerned elsewhere. This is not
so ,much a tendency to .:illfully brzal. ;:~~ lay. or to drive unsafely, but re per a ra„z..,,~on o.
human nature, the press of time, and the use of high-performance vehicles.
In 2004, in order to better conform to the intent of the federal standards as established in
FHWA's Manual of Uniform Traffic Control Device (MUTCD), and also to address some of the
widespread disregard of the 5 mph special downward speed zoning provision, the California
MUTCD (CA MUTCD) replaced the Traffic Manual, and the speed zoning section of the Traffic
Manual was changed to require rounding the 85~^ percentile to the nearest 5 mph increment
rather than the lower 5 mph increment. This specific guideline revision has resuked in raising
certain street speed limiu and has become a challenge to state and local jurisdictions.
However, in October 2007, the California Traffic Control Devices Committee (CTCDC) has
ruled to approve a language change in the California Traffic Control Manual to clarify how local
speed limiu may be set. CTCDC was prompted to make this change due to major variations in
the interpretation and application of the California Manual on Uniform Traffic Control Devices
(MUTCD) Section 28.13 section, to better distinguish the differences between "within" to "round
to the nearest" 5 mph (or setting local speed limits. The changes now include:
:• Posted speed limiu will be set "within" 5 mph of 85th percentile;
• Jurisdictions can lower this speed by an additional flue mph based on conditionslfactors
eked in the California Vehicle Code;
2 Posted speeds shall not be below the 50th percentile.
This issue is still an on-going debate. As of this writing, the Department of Transportation has
rescheduled a Special CTCDC meeting to discuss Agenda Item 09-10, Section 28.13 Speed Limit
Sign (R2- I) on March 19, 2009. The resulu of that meeting might have some bearing on this
study.

Work Plan
Our approach is based upon our extensive experience with speed and engineering surveys, as
well as the overall field of traffic engineering safety. TJKM will perform tasks as outlined below.
Task I.0 Kick-Off Meetin¢ and Coordination with Public Work a ~ t'ce D pattrcient
TJKM wrll meet with the City of Cupertino engineering (and enforcement) personnel to discuss
existing Issues, control devices, roadway and traffic conditions, roadway geometry, speed zones,
citizen complaints and collision data as it relates to the 67 roadway segments as shown
previously in the map figure.
TJKM's Project Manager, Christopher Thnay, will work with City staff to summarize action
items, detail the data requirements and report format, and set communication protocols, which
we will follow throughout the project. Mr. Thnay will be the main point-of-mnhct for City
staff, helping to achieve smooth flow of the project
Tack 2.0 Radar Field Data Colle~*i~~ Ana Cpeed Data A ix is
The most crucial component of a speed zone survey is the selection of locations for data
collection. The prevailing speed at the data collection point should be representative of the
entire speed zone segment and not too close to any traffic control device. Our experience
with other jurisdictions suggests that location near curves and shott speed zones should be
avoided. TJKM will work closely with the City and the data collectors to verity that the study
loatlons identified are adequate for sampling and will obtain City approval prior to proceeding
with data collection.
TJKM proposes to use National Data & Surveying Services/All Traffic Data (NDS/ATD) for data
collection. The NDS/ATD crew has conducted various speed data collection efforts using radar
devices for many cities and counties. Their recent experience includes collection for the City
o(Sacramento, Citrus Heights, Oakland, Vacaville and Fremont Radar technicians are all fully
trained and cettified in speed data collection and are equipped with certified equipment All
Traffic Data's field technician use their years of experience to selett the ideal spot for
collection and are trained to calibrate their equipment before each collection period to achieve
maximum accuracy.
Their pricing is reflected as a reimbursable expense in our budget As we have successfully
collaborated on many past projects, we are confident in our ability to work together to
successfully complete the project
Speed surveys will be performed with a calibrated hand-held radar gun. The calibration
certificate for radar gun will be included with the final report. Data will be colletted from an
unmarked vehicle parked in an inconspicuous location on the roadside. The calibrated radar gun
will be checked periodically with tuning fork. Only free Flowing vehicles in the traffic stream will
be included in the survey to establish normal speed conditions. The speed survey will not be
conducted in a construttion area, with or without traffic control devices, or in an area with
abnormal topography, visibility concerns, or hazards and inclement weather. Radar data
collected in the field will be used to calculate the SOrh and 85r^ percentile speeds, the 10 mph
pace speed, the percent of vehicles observed within the 10 mph pace speed, the range of speeds
observed, standard deviation, standard error of the mean and the average speed.

TJKM proposes to use the following measures to collect reliable data:
•3 A representative number of speeds will be obained by radar and recorded at each
location. Speed for a minimum of 100 vehicles per direction will be recorded in up to
two hours during non-peak hours. The speed survey shall be performed during off peak
hours. The radar survey shall not be performed during peak hours of 7:00 a.m: 9:00 a.m.
and 4:00 p.m.-6:00 p.m..
.• Record free-flowing vehicle speeds. If several vehicles are in a platoon, only the speed of
the first vehicle will be recorded.
B• Other field data will include reference of cross streets, weather conditions, beginning and
ending time, etc. Special evenu or conditions that could influence speeds will be noted.
Such condtions could include severe weather, maintenance acWities, stalled vehicle on
the roadway, etc. Our field crews will be empowered to postpone data collection if they
believe the data would be invalid for any reason.
Task 3.0 RoadwayySgglnent Characteristics
A field check will involve a professonal traffic engineer (California registered professional Civil
Engineer) driving each street while "floating' with prevailing traffic to determine the speed of
traffic from the driver's viewpoint. The engineer will evaluate the appropriateness of the 85th
percentile and will add the perspective of human judgment to set the appropriate speed limit
The final recommended limit will be determined by such factors as:
• prevailing speeds and volumes • horizontal and vertical alignment of the
•S roadside deveinnment roadway
•.• the number and location of driveways • superelevation
:• Intersections cin
• parked vehicles Pa g
•3 emergency shoulder areas • visibility and control
•.• schools and playgrounds •S landscaping
:• areas frequented by pedesttians :• accident history
Numerous other, less tangible factors also contribute to setting speed limits. We will be
especially cognizant of the factors not readily apparent to motorists, because this enables us to
justify reasonable speed limits that may be lower than what the numerical data alone suggest.
Task 4.0 Collision History Review and Accident Rate Calculations
Collision_history is very important in speed limit establishment and it is vital to become fully
aware of collision histories, collision problems and collision distributions.
For source data, TJKM tan either obtain the collision data from the City (hopefully in electronic
format) as indicated in the RFQ or TJKM will review the Statewide Integrated Traffic Records
System (SWITRS) collision reports or the nwst recent two or three-year period that is available.
TJKM has access to the SWITRS data for the past five years (2004 to 2008) and will be able to use
Intersection Magic to efficiently process the data for the study.
