Subject: Flint Center Events and De Anza College Quarter Rush Signal Timings
Dear Ray:
We are pleased to present this proposal to conduct traffic engineering services for the City of
Cupertino in conjunction with the Flint Center and the De Anza College. We have prepared
this Scope of Work based on our discussions with you on your needs for professional traffic
engineering services.
The Flint Center, located just east of State Route 85, hosts several events each week.
Between 800 to 2300 people attend an event at the Flint Center. Most of these events occur in
the evenings, after the PM peak period. Due to the close proximity of the Flint Center to the
SR-85 ramps, vehicles destined to the Flint Center often queue at the SR-85 ramps and along
Stevens Creek Boulevard. It is our underst~mding that new timing plans for special events at
the Flint Center and the quarter rush at De- Anza College will be developed as part of this
project.
SCOPE OF WORK
The scope of work below outlines in detail our proposed work plan to conduct the project.
Task 1: Data Collection
To evaluate the operations of the study intersections, DKS will collect traffic volume data
(turning movement count) at the four study iintersections. The intersection turning movement
counts will be collected manually at the following intersections:
• Stevens Creek Boulevard/SR-85 Southbound ramp
• Stevens Creek Boulevard/SR-85 Northbound ramp
• Stevens Creek Boulevard/Mary Avenue
• Stevens Creek Boulevard/Stelling Road

The intersection turning movement counts ~~vill be conducted before and through the start of
an event, and before and through the concl~.~sion of the same event. This count data will be
collected for up to three different sizes of events. In addition, we will collect turning
movement counts during the morning peak period on the first day of the Fall quarter of
classes at the De Anza College. The dates of the three events for which counts will be
conducted has not been determined at this ~~oint but will be determined in consultation with
Flint Center and City staff.
DKS also plans to collect 24-hour mechanical mid-block counts at up to five locations during
the days intersection turning movement counts will be conducted. Tube counts will be placed
at the garage entrances for at least one 24-hour period.
These mechanical count information will 1-elp determine the event plan introduction time.
The counts from the mechanical counts will. be graphed so that the various traffic levels can
be readily identified. The locations of the mechanical counts will be determined.
Task 2: Traffic Signal Re-Timing
This task consists of the development and implementation of new signal timings for the four
signals along the study corridor. We will develop coordinated signal timing plans for all
identified signals.
We will use Synchro and SimTraffic to develop the event signal timings. The timing plans
will specify the cycle length, phase split, off;;et, phase sequence, and other parameters that the
local system allows to be changed on a timi~ag plan basis. We will specify the times of each
specific day that the event signal timings will need to be in effect to accommodate specific
sizes of events at the Flint Center. In addition, we will review existing parameters such as
pedestrian crossing times and other volume-density settings where they are used to help
improve the corridor's efficiency.
All timing plans presented for review will be fine-tuned in the software, and not just raw
output from optimization models. -The event plans will consist of multiple plans targeted at
certain attendance projections for the Flint Center. Out initial data collection efforts will
focus on the following event sizes:
• De Anza College Quarter Rush
• ,Event Plans for expected attendance of 1000 or less
• Event Plans for expected attendance between 1000 and 1800
• Event Plans for expected attendance over 1800
Based on feedback from the Flint Center and City staff, the variations in attendance figures
for the events will be modified to better accommodate the different types of events.
DKS will submit draft timing plans to the City of Cupertino for review. This submittal will
document the expected operation of the sip;nals using time-space diagrams, time-location
diagrams, ad measures of effectiveness reports created by the simulation models. We will
meet with the City to discuss the comments a~1d modify the plans as needed.

DKS will assist the City in implementing and fine-tuning the new coordinated signal timing
plans for each signal. This work will include:
• Entering the new timings into the Street~'Vise database;
• Setting the parameters for automatic implementation of the timings;
• Conducting field observations to fine-twee the timings during each of the four event plans
developed;
• Making adjustments to the signal system database based on changed determined during
the field observations.
DKS staff will be present during timing pl<<n implementation for fine-tuning. It is assumed
that the City will take the lead on the timing implement into the Streetwise database.
Deliverables: Traffic signal timing sheets ready for implementation.
Final implemented and fine-tuned event signal timings and evaluation of
implemented timing plans.
FEE
Our fee to perform the services described above is $15,800. The services will be conducted
on a time and materials basis in accordance with our standard hourly billing rates. This fee is
based upon the Scope of Work described above and includes all direct expenses and
administrative support.
SCHEDULE
DKS will provide a draft of the proposed signal timings with time-space diagrams within four
weeks of receipt of the traffic counts. Final. timings will be submitted, including time-space
diagrams, within two weeks of receipt of comments on the draft signal timings.
We thank you for inviting us to submit this :proposal to conduct services for this project. We
look forward to working with you. Should you have any questions, please do not hesitate to
call me or Shirley Chan.
Sincerely,
DKS Associates
