Re: Proposal for Traffic Operations Analysis for De Anza & Pacifica/McClellan
Dear Mr. Stillman:
Hexagon Transportation Consultants, Inc., is pleased to submit this proposal to prepare a traffic operations
analysis for the intersection of De Anza Boulevard & Pacific Drive/McClellan Road. At this intersection
McClellan Road and Pacifica Drive are offset and have been curved to meet at a single intersection.
Because of the curved alignment, the cross-streets must run as split phases at the signal. This decreases
the green time for De Anza Boulevard and leads to long back-ups. Another issue is the gas station
driveway that is oriented across from McClellan Road, which creates a potential conflict with vehicles that
do not necessarily see each other.
The purpose of the study is to explore options for revamping the intersection to allow more greentime for
De Anza Boulevard. One option is to straighten the cross streets and create two"T"-intersections operating
off a single controller. This design would lessen the conflicts at the gas station driveway. Hexagon will
study the signal phasing and queuing with this option. If the realignment proves to be unworkable,
Hexagon will explore other options to make the gas station driveway safer.
Our scope of work includes creating a Synchro and Simtraffic traffic simulation of the intersection to test
the realignment option. An important issue will be the queuing between the two"T"-intersections because
the queue space is limited. Our scope of work also includes a peer review of the realigned signal design
that you already have created. If the realignment would not function because of queuing limitations, we
would study options for improving the existing intersection alignment, especially with respect to the gas
station driveway.
Scope of Work
Data Collection. Hexagon will conduct intersection turning-movement counts of both vehicles and
pedestrians for three hours in the morning and three hours in the afternoon. Also, we will observe the
signal timing, and we will measure the minimum, average, and maximum queue lengths. These data will
be necessary to calibrate the Synchro model.
Synchro/Simtraffic Model Creation. Hexagon will create a model of the intersection using the Synchro and
Simtraffic software. This model will cover the AM and PM peak three-hour periods and will show the traffic
flows, signal operations including pedestrian phasing, and queue lengths. It will be calibrated to existing
conditions.
Realignment Evaluation. Hexagon will use the model to evaluate the potential realignment of the
intersection into two"T"-intersections. Of particular interest will be the queuing between the intersections.
We will note whether unacceptable back-ups would occur. The simulation will also include the crosswalk
across De Anza Boulevard. The signal timing within the model will allow enough greentime for pedestrians
to cross the street.
Signal Design Peer Review. Hexagon will review the conceptual signal design that you have prepared. We
will note the locations of poles, signal heads, and detectors. To reduce the cost of the potential
modification, we will try to reuse as much existing signal equipment as possible.
Recommendations. Hexagon will provide recommendations for the signal design and operations of the
potential realignment scheme, assuming that it can be made to work. If the realignment option would result

in unacceptable operations, Hexagon will make recommendations to make the existing intersection
alignment as safe and efficient as possible. Particular attention will be paid to the gas station driveway.
Schedule and Budget
The study will take three weeks to complete. It will be necessary to complete the traffic counts before the
week of Thanksgiving. After that, traffic conditions do not return to normal until mid-January. The cost for
the study will be$9,975. You may authorize us to proceed by sending a Purchase Order. If you would
prefer, we can send a standard contract.
We appreciate the opportunity to submit this proposal for your consideration. Please do not hesitate to
contact us if additional information is needed.
Sincerely,
HEXAGON TRANSPORTATION CONSULTANTS, INC.
