City of Culver City, California
City Council Agenda Item Report
RECOMMENDATION:
Staff recommends the City Council authorize entering into a professional services
agreement with KOA as the most responsive and qualified firm to develop optimized
traffic signal timing plans and flow charts at 26 signalized intersections along
segments of the Jefferson Boulevard, Sepulveda Boulevard, Overland Avenue, and
Slauson Avenue major street corridors.
This expense will be funded by Playa Vista Mitigation fund. Upon approval of the City
Council, staff will make a budget transfer to allocate funding to project No. 880 –
Traffic Signal Synchronization studies.
A 4/5
th
vote is required to approve the budget amendment.
BACKGROUND/ DISCUSSION:
Increased construction and fuel costs with growing vehicular traffic volumes and
changing driving patterns promotes the need to increase the efficiency of the existing
traffic signal system. One cost effective strategy that is easy to implement is the
improvement to the traffic signal operation through coordination and optimization.
This effort is often recommended to be accomplished in five (5) to ten (10) year
increments.
The widening of Overland Avenue north of Washington Boulevard, increased
passengers through the LAX airport facility, and the rerouting of the Culver City Bus
Route number three (3), have added to the vehicular changes and patterns on

City Council Agenda Item Report
Jefferson Boulevard, Sepulveda Boulevard, and Slauson Avenue. In addition, there
are future projects on the horizon such as the LAX expansion, West Los Angeles
College expansion, Symantec and Fox Hills Mall developments, and the population
increases at the Playa Vista development in Los Angeles.
DISCUSSION:
Two (2) MTA grants, in the past ten (10) years, the Sepulveda Boulevard Automated
Traffic Surveillance and Control (ATSAC) system and the Jefferson Boulevard ATSAC
gap closure projects were responsible for projects that upgraded sixteen (16) and
twelve (12) signalized locations, respectively. The upgrade mainly provided for the
installation of sophisticated traffic signal controllers. At the time of those installations,
the timing of the traffic signals was based on available traffic volume data for each
intersection with coordination between signalized intersections determined from field
observations.
Recent developments in traffic signal computer modeling programs provide for
determining and evaluating various strategies involving cycle lengths, phasing
sequence, splits (proportioning of the traffic signal length) and coordination points with
displays represented on a computer monitor. The model will address vehicular
demand by allocating green time to equalize the degree of saturation on each
vehicular movement followed by coordinated traffic signal cycle lengths to promote
progressions, minimize delays, maximize storage area and when possible
accommodate pedestrian crossings.
Engineering Division staff prepared and sent out five (5) requests for proposals (RFP)
for professional Traffic Engineering services in providing, at twenty-one (21) signalized
intersections, traffic signal optimization timing plans. The RFP was sent to the
following Traffic Engineering firms.
1. Austin Foust Associates
2. Crain and Associates
3. Katz, Okitsu and Associates
4. Wilbur Smith and Associates
5. Willdan
The following firms submitted a proposal which included their estimated cost for the
requested effort.
Company Proposal Fee
Austin Foust Associates $ 29,400City of Culver City, California
City Council Agenda Item Report
Willdan $ 31,500
Katz, Okitsu and Associates $ 35,650
Staff reviewed the proposals and three responding firms provided a summary of the
effort each would perform in keeping with the tasks requested in the RFP. Austin
Foust indicated that they would provide timing charts in the LADOT-ATSAC format
and not standards as stipulated in the RFP. Also Willdan failed to recognize this
requirement. The KOA proposal is complete and responsive to the requirements
stipulated in the RFP. In addition, to process the optimization program model, KOA
will, as part of this effort, prepare recommendations for potential minor signalization
improvements and revised minor phasing. Although KOA’s cost is the highest, staff is
recommending awarding them the contract based on their well written proposal,
superior experience, and successful working relationships with City staff on past and
current projects.
KOA has been involved in several traffic signal improvement projects over the past
fifteen (15) years within the City of Culver City. The most recent was the Washington
Boulevard realignment evaluation. An integral part of this evaluation was the retiming
of seven (7) traffic signals in the downtown area. Their successes in satisfactorily
completing traffic signal timing work in the city yields a high degree of confidence that
the desired work can be accomplished within the RFP framework. KOA is also
providing consultant services for the Sunkist Park Neighborhood Traffic Management
Plan.
It was suggested from Public Works signal field staff to include an additional group of
five (5) signalized intersections, on Overland Avenue and additional intersections on
Slauson Avenue, as part of this effort. This would increase KOA’s cost proposal by
$8,500 (approximately $1,700 per location) to $44,150.
Therefore, staff is recommending that the City Council award an agreement with KOA
in an amount not-to-exceed, $44,150, to provide traffic signal timing optimization plans
and charts at 26 intersections. The work is expected to be completed by December
2006.
FISCAL ANALYSIS:
Negotiations regarding mitigation measures for traffic related impacts within the City of
Culver City resulting from the build out of Phase 1 of Playa Vista yielded a deposit of
$1,250,000. These funds are in account number 420.212270 (Deferred Revenue).
There is $1,238,821.89 of unreserved funds in the account. Support for a battery
back-up system at several signalized intersections and reimbursement of grant City of Culver City, California
City Council Agenda Item Report
matching funds for the traffic signal upgrades in the Jefferson Boulevard and
Sepulveda Boulevard corridors were previously funded from this mitigation account.
There is a nexus to accomplish this signal timing optimization effort at this time
because we are at a half way milestone to the full Playa Vista build out expected in
2011. Therefore, it is recommended that Playa Vista funds be used to pay for this
work.

ATTENTION: Mr. Max Paetzold
SUBJECT: TRAFFIC SIGNAL OPTIMIZATION EFFORT
Dear Sir:
Austin-Foust Associates, Inc. (AFA) is pleased to respond to your RFP dated April 26, 2006 to provide
optimized signal timing for 21 locations 13 of which are multi-purpose intersections. Our understanding
is that the consultant will prepare a computerized traffic flow simulation program which will, in turn,
produce optimized signal timing patterns. The timing charts will be in the LADOT-ATSAC format The
consultant will be responsible for development and calibration of the model but the City will furnish the
AM/PM and midday peak hour turning movement counts at the 13 multi phase locations along with
existing timing charts. The signal optimization will be based upon existing intersection lane
configurations and signal phasing — no new improvement to the existing geometry is planned. City Staff
will install the recommended timing plans in the field controllers and the consultant shall evaluate the
results and provide recommendations for any fine tuning that may be needed.
AF'A's approach to this project is to utilize Synchro Software to provide the basic traffic flow simulation
program. However, the key to success of any flow simulation is to properly calibrate the simulation
model to accurately replicate existing conditions. Then after the model is calibrated it can be used to
optimize signal timing patterns. In order to ensure proper calibration, AFA will conduct observations of
start-up lost time, yellow extension, saturation flow rates and maximum back up queues at six of the 13
multi phase locations. The Synchro traffic flow simulation will be adjusted using the field measured
parameters to produce model results similar to those observed in the field. Only after this thorough
testing and calibration effort can the model be "trusted" to produce optimal and reliable future timing
patterns.
AFA has used essentially this same calibration process for many signal timing optimization programs
with the entire City of Aliso Viejo being our most recent project. Our approach there, as will be done
here, was to calibrate the model, then optimize signal timing followed by field implementation and fine
tuning The only difference is AFA conducted the initial traffic counts as well as before and after floating
car travel time runs.

Based on the City providing the traffic counts and floating car travel time data, AFA proposes to develop
and calibrate the Synchro model, produce optimal timing patterns and perform an after field review for
fine tuning purposes for a fixed fee of $1,400 per intersection for a total cost of $29,400.
I will be the Project Manager and you contact person. We realize it may be difficult to evaluate our
proposal simply from the brief letter. Therefore, we would be pleased to demonstrate to you our typical
Synchro traffic flow simulation (probably using our recently completed Aliso Viejo model) if you have
the time and interest. If you have any questions, please feel free to call. We would like to talk more
about our approach.

Our staff includes 13 registered civil engineers and/or registered traffic engineers. The company has strong
expertise in transportation engineering and in project management. We have served in key roles on many
of the largest transportation projects in Southern California. The company has applicable experience in
project management and in all project phases where transportation expertise is required. We have strong
CAD capabilities, using both AutoCAD and Intergraph MicroStation. The firm's capabilities and experience
include a wide range of work for public agencies and private developments. Specific areas of expertise
include:
The Katz, Okitsu & Associates team prefers the use of
SYNCHRO as a tool for development of signal timing
plans. We have been using this program nearly
exclusively in our recent signal timing projects, and we
have retimed nearly 1000 traffic signals using this program.
SYNCHRO is a modern and easy-to-use windows-based
program that has been designed to properly handle many
of the common issues that cannot be analyzed with legacy
programs, such as Passer2 or TRANSYT-7F. These
include comparison between free vs. coordination
operation, unequal cycle lengths, arterials and grid
networks, and explicit handling of actuated controllers.
The program has greatly improved our ability to deliver
more properly fine tuned plans to the street It has also
provided a well-designed geographic database for maintenance of traffic volumes and signal timing
parameters. Its companion program, SimTraffic, also allows for a very convenient and realistic real-time
animation of simulated or existing timing plans and of the proposed, improved or optimized timing plans.
This is very effective for analyzing over-saturated networks or unusual features that cannot be properly
modeled by traditional software.

As seen, these two exhibits show the typical SYNCHRO printed

The program includes numerous other reports. The Katz, Okitsu &
Associates team can also provide timing plans using Passer2,
TRANSYT-7F, or other programs. However, we do not recommend
use of these programs for this project. If the participating agencies
were not familiar with SYNCHRO, we would request an opportunity
to make a presentation of the program for your evaluation. We are
confident that you will agree with our recommendations.
Signal timing software can provide valuable information; however,
practical experience is also essential in a signal timing study.
Traditional methods such as time-space diagrams are frequently as
effective as computer generated solutions; also, knowledge of the
practical limitations on maximum green intervals and judgment of
pedestrian traffic actuations and their effects. Katz, Okitsu &
Associates has extensive experience in signal timing that is used in all
of our signal timing plan development activities. Fortunately,
SYNCHRO also has a very convenient time space diagram display and
editing feature that facilitates the manual adjustment of optimized
timing plans, as well as the performance changes that result from
those manual adjustments. The Time Space Diagram can be displayed
vehicular flow style that is becoming more and more popular in the Traffic
in traditional band style or in a
community.
Katz, Okitsu & Associates normally employs software as appropriate to assist in developing and evaluating
traffic signal plans. This software is useful in identifying appropriate concept signal timing plans, cycle lengths,
and splits for study networks. It is important to stress that we use this software as tools, not as mandates.
In fact, we normally expedite timing plans onto the street, because study resources are often better spent
in fine-tuning than in exercising software. This is particularly true for locations that are experiencing near-
capacity conditions and severe congestion.
We are highly qualified to provide Culver City with the expertise necessary to conduct the necessary work
for this project. Many of our projects are performed directly for public agencies or for other firms working
directly for public agencies. We have extensive knowledge of the special needs and requirements of public
agencies, and we approach all of our projects in the best interest of the public agency. We have completed
numerous signal timing and other traffic engineering projects under direct contracts with many public
agencies throughout Southern California,

Washington Boulevard Realignment Feasibility per
Study, Culver City, California (2005): The City of
Culver City has retained Katz, Okitsu & Associates to
evaluate the feasibility of realigning Washington Boulevard
from Ince Boulevard to its easterly intersection with
Culver Boulevard. A goal of the project is to recover the
land now dedicated to street use and to expand a
pedestrian plaza or provide other amenities that are not
now possible. Washington Boulevard would be realigned
to intersect with Culver Boulevard near the existing Ince
intersection, and Ince Boulevard would generally be
incorporated into the realignment Katz, Okitsu &
Associates analysis focused on the significant and complex
traffic operation issues in the study area due to the
confluence of Culver Boulevard and Washington Boulevard and the heavy traffic flows that travel along
Culver Boulevard between the easterly and westerly intersections. The City wished to maintain good
pedestrian circulation in the downtown area, a goal that is difficult to achieve in conjunction with the traffic
carrying function of Culver Boulevard. We evaluated existing conditions in the project vicinity to
determine whether features of the existing circulation system are not functioning at optimum levels or as
intended in studies completed in the past. In analyzing the alignment, we used the Synchro traffic signal
simulation and optimization program to assess traffic conditions to determine whether existing conditions
can be improved readily and simply by evaluation and retiming of the signal system. Through this an
optimized timing plan was developed and implemented to greatly improve existing conditions. Reference:
Mr. Todd Tipton, City of Culver City, (310) 253-5783 or email: todd.tipton@culvercity.org.
Santee Signal Timing, (2004): Katz, Okitsu & Associates
was retained by the City of Santee to create citywide traffic
signal timing plans. The project area, which is completely
within the City of Santee, consists of 44 existing traffic signals.
The project deals with 44 intersections along eight arterials.
Santee is the only City in San Diego County to own and
operate an Econolite signal system. This makes the City very
unique and requires a specialized knowledge of this type of
signal system to properly time the trafficsignals. The project
included simulation and optimization model for the entire City
of Santee including a 9-phase intersection with the ninth phase
serving the San Diego Trolley traveling on street through the intersection of Mission Gorge and Cuyamaca
Avenue. The system is comprised of an Econolite Aries system with AS2C system controllers.

Signal System Troubleshooting & Timing, National City, California (on-going): Katz, Okitsu &
Associates is currently working under an as-needed contract to provide traffic signal system support. The
first task was to reassemble the BiTran server and restore communication to all interconnected
intersections, including troubleshooting of fiberoptic modems. This task has been completed. The next
phase was to restore operational coordination timing plans, where valid and compatible with existing signal
designs. However, this phase determined that many of the existing plans are not compatible with recently
modified signal phasing and others are not functional. As part of the final phase, new coordinated traffic
signal timing will be implemented over the major cooridors of the City using a Synchro network to be
created. Reference: Mr. Din Danesh far City of National City (619) 336-4387.
Alessandro Boulevard Traffic Signal Timing Project, Moreno Valley, California (2004): Katz,
Okitsu & Associates conducted a traffic signal optimization study for the City of Moreno Valley on this
heavily used east/west arterial that passes through the center of the City. This project was the fourth
traffic signal optimization project undertaken by our firm for the City of Moreno Valley. In conjunction
with coordination activities, pedestrian clearance intervals were modified to comply with new Federal
guidelines and volume density settings were applied to actuated approaches. Corridor travel speeds along
the arterial were increased by 20% to over 30 mph, average, for all time periods. Reference: Mr. Alan
Kashefl, Associate Traffic Engineer, City of Moreno Valley (909) 413-3145.
Euclid Street Traffic Signal Coordination Study &
Implementation, Garden Grove, California (2003-
2004): The City of Garden Grove obtained funding to
retime the traffic signals along Euclid Street for its entire
length within the City, from Orangewood Avenue to
Westminster Boulevard. Katz, Okitsu & Associates was
retained to conduct the timing study and to implement
the final timing plans at the City Traffic Control Center
and at intersection controllers. The corridor has 12
traffic signals including a ramp for the SR 22 Freeway. The
signals use Econolite controllers and the Aries traffic
management system. Katz, Okitsu & Associates used the Synchro program to establish timing plans and
provided full implementation and fine-tuning services. The plans were developed to readily extend along
crossing arterials that will be retimed in the future. The plans have been implemented for AM, PM, off
peak and weekends_ The corridor now experiences travel times that are 25% better than base line
conditions. Reference: Mr. George Allen, City Traffic Engineer, City of Garden Grove (714) 741-

Our designated Project Manager is Rock Miller, P.E.,
P.T.O.E. Mr. Rock Miller is registered as a Traffic
Engineer and Civil Engineer with 30 years of traffic
engineering experience. He has extensive experience in
conducting signal-timing studies. He will be responsible
for all phases of the project, including coordination with
the City, supervision of timing studies using software,
evaluation and fine-tuning. Mr. Miller was responsible for
traffic signal timing while serving as the City Traffic
Engineer at the City of Costa Mesa, where he developed
a unique and responsive approach to signal timing on high

the Sydney (Australia) Coordinated Adaptive Traffic
(SCAT) signal timing system. Under Mr. Miller's approach,
splits were constantly adjusted based upon occupancy data
This method allowed the signals to be much more respo
Mr. Miller logged 100's of hours on the Costa Mesa's signal
Since leaving Costa Mesa, Mr. Miller has conducted timing studies for numerous public agencies. These
include "hands on" timing studies for the Cities of Garden Grove, Irvine, Moreno Valley, El Cajon, National
City, Carson, Long Beach, and San Clemente. For these studies, Mr. Miller and staff were responsible

correspondence, meetings, Email, telephone calls and other management techniques utilized for design
projects. Meetings to provide updates to the participating agencies are anticipated for the preliminary
submittal of timing plans, the final accepted timing plans and at the end of the project.
• Instructor - Fundamentals of Traffic Engineering: Katz Okitsu & Associates' Principal Mr. Rock
Miller is retained by the University of California, Institute of Transportation Studies, to make
presentations for this widely attended class that is presented several times each year throughout
California. He is the lecturer for topics including Highway Capacity, Level of Service Analysis for
highways and intersections, and Intelligent Transportation Systems.
• Honolulu Phase I Signal Re-timing Project, Honolulu, Hawaii: Principal-in-charge. The City and
County of Honolulu, Hawaii is undertaking a three-year program to re-time and optimize all 700 traffic
signals on the island of Oahu. Katz, Okitsu & Associates was retained to conduct a study to evaluate
existing conditions and prepare plans for the re-timing of the first study phase, 300+ intersections.
The Synchro program is being used for the first time in the State for this project. Study routes include
the high volume route from the Airport to Waikiki Beach, as well as other major access routes to the
downtown area. The routes are subject to heavy congestion, with backup through closely, spaced
intersections in many study areas.
• Euclid Street Traffic Signal Coordination Study & Implementation, Garden Grove,
California: Principal-in-Charge. The City of Garden Grove obtained funding to retime the traffic signals
along Euclid Street for its entire length within the City, from Orangewood Avenue to Westminster
Boulevard. Katz, Okitsu & Associates was retained to conduct the timing study and to implement the
final timing plans at the City Traffic Control Center and at intersection controllers. The corridor has
12 traffic signals including a ramp for the SR 22 Freeway. The signals use Econolite controllers and the
Aries traffic management system. KOAA used the Synchro program to establish timing plans and
provided full implementation and fine-tuning services. The plans were developed to readily extend
along crossing arterials that will be retimed in the future_ The plans have been implemented for AM,
PM, off peak, and weekends. The corridor now experiences travel times that are 25% better than base
line conditions.
• Bay Area Regional Traffic Signal Optimization Project: Project Manager. KOA was named to
MTC's consultant bench for the RTSOP program in 2006. Mr. Miller is currently working on projects
with the Cities of San Francisco, San Leandro, Lafayette, and San Ramon. The San Ramon project
includes over 60 traffic signals and includes retiming of the Crow Canyon Road corridor that was timed
by our firm in 2000. The San Francisco project includes the Market Street and Embarcadero corridors
where transit priority will guide the signal timing efforts. KOA was selected to this bench based upon
our strong qualifications and references that included signal timing projects for other Bay Area
communities, including Oakland, Alameda, and Martinez.

done this year (2004). The traffic signals along each corridor were not operating in a coordinated
mode prior to this timing study. Timing plans were prepared for all time periods using Synchro
software. After Karla, Okitsu & Associates inputted the timing plans, in close cooperation with the City
of Moreno Valley staff, the traffic along each arterial significantly improved.
STEPHEN S. CHANG, AlCP — NETWORK DESIGNER
Mr. Stephen Chang, AICP, is an Associate Transportation
Planner with over six years of experience involving
transportation projects. He has excellent technical
writing skills, and has prepared traffic impact analysis and
circulation studies for private developments in many
areas of Southern California. He experience includes:
preparation of Caltrans-related studies including Project
Study Reports and warrant analysis; residential traffic calming projects in established communities; traffic
modeling assessments; and private community evaluations. He is also proficient in the use of intersection
capacity and signal timing software.
• Crow Canyon Area Signal Re-timing Project, San Ramon, California: Network Designer. Mr.
Chang entered traffic volume peak hour data and set-up the Synchro Traffic Signal Timing model for
over 30 intersections in the City of San Ramon, along an important commuter arterial. The project
was conducted and managed at our Orange County office. The existing signal system is based upon
Wapiti software for Model 170 controllers. This type of system is relatively rare in California. The
results of optimization suggest that substantial traffic performance improvements will be attained during
implementation.
• Base Line Road Signal Timing Project, Highland, California: Network Designer. Mr. Chang set-
up the Synchro Traffic Signal Timing model for the City of Highland, Caltrans, and a private developer
to provide signal re-timing and coordination services for Base Line at SR 30 Freeway ramps and two
adjacent City intersections in the City of Highland. The ramp intersections experienced significant AM
period congestion prior to study activities. The Synchro program was utilized for development of
timing plans. The SimTraffic module of the program showed the dramatic effect of changing phase
recall strategies upon congestion at the site.
• Alhambra Avenue Signal Timing, Martinez, California: Network Designer. Mr. Chang imputed the
data and constructed the signal timing model for the study. Alhambra Avenue is an important
north/south arterial providing access from the Route 4 Freeway to the traditional downtown and the
John Muir Home Historical site. Katz, Okitsu & Associates prepared traffic signal timing for 9
intersections along Alhambra Avenue. Signal Timing plans took in consideration three new signals and
revised striping in the project area. The project area also included two state highway on- and off-ramps
intersections at the Route 4 Freeway. SYNCHRO software was used as a data manager and for
optimization of traffic flows.
• Perris Boulevard Signal Timing, Moreno Valley, California: Network Designer. Mr. Chang set-up
and entered the data for I I signalized intersections on Perris Boulevard in the City of Moreno Valley.

The Firm also conducted travel time and delay studies along Perris Boulevard within the study limits
before and after the timing activities. Timing plans were prepared for all time periods using Synchro
software. After Katz, Okitsu & Associates inputted the timing plans, in close cooperation with the City
of Moreno Valley staff, the traffic along Perris Boulevard significantly improved.
Katz Okitsu & Associates is focused on continuous improvement. Consequently, the company has in place a
formal Quality Assurance program for all of our engineering and planning projects. To ensure continuity
and adherence to budget and schedule, a Project Manager and project team conducts the project from
inception to the completion of the final engineering and/or planning documents. There is an ongoing focus
to the fundamentals of technical management and design quality: field reviews and data collection, project
planning, documentation, reviews, and milestone checkpoints. Formal quality control and ergonomic
checklists are employed.
The professionals proposed for this project have been identified first, for their ability to meet anticipated
program needs, and second, for their ability to support the project's staffing requirements in a timely and
through manner. The very nature of such programs requires that professionals assigned to the project
work in a focused manner (100%) on the project at times, while at other times the support they need to
provide is somewhat less. Indeed, successfully distributing multiple assignments over each professional in a
consulting firm is how we can provide services to our clients on a cost-effective basis.

Contact information is as follows: Katz, Okitsu & Associates, 17852 E. Seventeenth Street, Suite 102,
Tustin, California 92780-2142, Tel: (714) 573-0317, Fax: (714) 573-9534, Email: Rrnirler(&katzokitsu.corn.
Task 2 - Existing Facilities Analysis & Data Collection
2.) - Crossing or Continuing Arterial Coordination
Katz, Okitsu & Associates does not ignore existing signal timing plans on cross streets or extensions of
study area streets while performing any timing project. Our normal approach is to identify existing crossing
or continuing arterial coordination plans, if any, and build new plans around these intersections, where
feasible or appropriate.
2.2 - Intersection Inventory
An inventory of intersection physical conditions will be conducted for each location. This will include
assessment of intersection configuration, peak hour traffic conditions, existing signal timing and phasing,
intersection spacing, prevailing cruise speeds, and other traffic data. All information required to prepare
and calibrate the proposed traffic signal timing software will be collected or evaluated from data or field
inspections.
Katz, Okitsu & Associates
Planning and Engineering IiProposal to the
City of Culver City
Traffic Signal Optimization Effort
If permitted, we will propose to open each traffic signal controller cabinet briefly to inventory phase
assignments and directions. This process often determines that signal phasing is not consistent with office
records. By identifying proper phasing early, problems associated with implementation can be greatly
reduced.
The precision of the traffic network is of critical importance. Lane groups will be established to capture all
distinct movements at an intersection. Lane groups will include exclusive left- and right-turn lanes, through
movements and shared movements as necessary.
2.3 - Traffic and Turning Movement Counts
The Traffic Solution will provide two-hour traffic turning movement counts for the AM peak, the mid-day
peak, and the PM peak for all locations for this project. These counts will be required to conduct traffic
signal timing studies. The hour of counts will be 6:30-8:30 am, 11:30 am-1:30 pm, and 4:00 to 6:00 pm on
weekdays.
2.4 - Speed and Delay Studies
The City will be responsible for conducting floating car studies of speed and delay. This information is
useful in evaluating the effectiveness of signal timing plans.
Task 3 - Development of Signal Timing Plans
3.1 - Input Coding
Katz, Okitsu & Associates will prepare Synchro models for all time periods for the study area. The
network will be built upon a scale map of the study area. The map will show all arterial highways and
signalized intersection locations, at minimum. Data required to operate Synchro will be coded to create
model versions of the highway system. This includes geometric information, traffic volumes, and signal
timing parameters.
The signal timing model will be calibrated to show existing traffic volumes, existing signal phasing, and
existing traffic patterns. The results of the calibration will be carefully compared with existing conditions
to insure that the current operation is closely replicated and that all model input parameters are accurate.
The SimTraffic module of Synchro will assist in verifying the existing signal operation and roadway
geometrics.
3.2 - Evaluate Phase Sequences and Strategies
It is the objective of any traffic signal timing project to maximize green opportunities on major arterial
roadways while minimizing delay on cross-street. In order to achieve this objective, Katz, Okitsu &
Associates will evaluate existing traffic signal phasing and splits to determine if they optimize intersection
and system-wide operations. Alternative signal phasings will be tested as the study evolves and as data
200 suggests.
ES
Katz, Okitsu & Associates
Planning and Engineering 12Proposal to the
City of Culver City
Traffic Signal Optimization Effort
Frequently, overall system timing can be improved through changes in existing conditions at selected
intersections. This is particularly true when existing signal phasing or channelization results in the need for
excessively long signal cycle lengths. Split phased intersections with pedestrian crossings on both legs are
typical examples of locations that may dictate system cycle length requirements. Other channelization or
signal control improvements at multi-phase intersections may reduce the need for traffic signal capacity for
left-turn lanes. Katz, Okitsu & Associates will analyze existing conditions and prepare recommendations for
potential minor signalization, timing, or channelization improvements that may be appropriate for
implementation in conjunction with this project.
3.3 - Preliminary Timing Plans
After calibration is completed and pronounced final, Katz, Okitsu & Associates will use the Synchro
program to develop optimized timing plans that will minimize overall system delay and also minimize stops
along arterial through routes. The model is then fine tuned using the time space diagram editing
procedures to insure smooth traffic flow without reducing system performance. The optimization
procedure is repeated several times and the performance results are benchmarked. This helps to insure
that the final plans are fully optimized, since Synchro often is unable to find a superior plan using its hill-
climbing method unless its starting point is compatible for finding the best plan.
Frequently, a recommended timing plan can be prepared without use of alternative signal phasing strategies,
such as lead/lag. This is clearly true for networks of two-phase signals and often true for signals at spacings
of one-half mile or longer. However, for closely spaced intersections (one-quarter mile or less) with left-
turn phases, it is often possible to greatly reduce stops by utilizing alternative phasing strategies. We will
work to be consistent with local preferences for special phase sequences, since they can generate confusion
to some motorists. We will advise the City of situations where lead/lag phasing may be most effective.
The results of the signal timing runs will be discussed with the City for potential implementation. Data will
be collected only for weekday AM, off peak, and PM; however, the proposed timing plans may be applicable
or additional timing plans will be considered and generated for other study periods, using global
adjustments to the collected data. Where system timing plans do not appear to be justified for all hours,
isolated actuated operation will be recommended.
3.4 - Final Timing Charts
Katz, Okitsu & Associates will prepare timing charts showing all information that will be required for data
entry and programming of existing signal controllers for system operation. Parameters or timing sheets will
be provided in the format desired by the City (LADOT — ATSAC standards). Timing plans will be prepared
for the AM Peak, PM Peak, Off-Peak. Suitable plans will also be prepared for weekend periods; however,
weekend counts will not be obtained.
