RE: Proposal and Letter of Agreement to provide engineering services in the preparation of
a grant application for Traffic Light Synchronization Funds
Dear Ms. Daneshmand:
Barton-Aschman Associates, Inc. is pleased to submit this proposal to provide professional
transportation engineering services. This project is in one of Barton-Aschman's areas of
greatest technical strength and experience -- traffic operations. We have completed many
similar projects during the past few years and are extremely interested in assisting the City
of Coppell in securing funds for traffic signal improvements. Based on our discussions with
you and on our unparalleled experience in projects of this type, we have prepared a Scope of
Services for this project.
If accepted, this letter will become an agreement between the City of Coppell and Barton-
Aschman Associates, Inc. to provide the services outlined in the Scope of Services contained
in this letter.
FIRM INFORMATION
Barton-Aschman Associates, Inc. was incorporated in 1959. The company's headquarters
are located at 820 Davis Street, Evanston, Illinois, 60204-1381. The Dallas office was
opened in 1981 and is located at 5485 Belt Line Road, Suite 199, Dallas, Texas, 75240. The
Fort Worth office is located at 2630 West Freeway, Suite 242, Fort Worth, Texas, 76102,
and was opened in 1990.
BACKGROUND
The nucleus of the present firm was organized by George W. Barton in 1945. From its
inception, George Barton's practice was oriented toward traffic engineering operations and
urban transportation planning. In 1958, Frederick T. Aschman's private planning practice was
merged with that of Mr. Barton's. This merger enabled Barton-Aschman to focus both
engineering and planning skills on resolving urban and regional problems. The firm has over
forty years of practical traffic en. gineering.and operations experie, nce.
The professional staff is comprised of over three hundred and thirty men and women, many
of whom have worked for municipal and state agencies as practicing traffic engineers, city
ers, and directors of public works.

Barton-Aschman has a long history of providing quality services in traffic engineering and
operations, signal system design and timing, and preparation of plan specifications for signal
system installations. Barton-Aschman has provided consulting services to more than three
hundred fifty cities throughout the United States and Canada.
The firm maintains nineteen offices throughout the United States with the Dallas office being
the hub of signal system design and timing practice area. Other Barton-Aschman offices
include Ft. Worth, Texas; Evanston, Illinois; Washington, D.C.; Minneapolis-St. Paul,
Minnesota; Southfield, Michigan; San Jose, Berkeley, Riverside, Pasadena, Orange County and
Sacramento, California; Columbus, Ohio; Honolulu, Hawaii; Fairfax, Virginia; Fort Lauderdale,

RELATED EXPERIENCE
Barton-Aschman Associates (BA) has taken the lead among Texas Consultants in the State
sponsored Traffic Light Synchronization (TLS) program. With the addition of the Fort Worth
Barton-Aschman office we are directing the activities of nine (9) TLS projects during Phases
I and II. Phase I projects include the Cities of Duncanville, Fort Worth, Garland, and Hurst.
Phase II projects include the cities of Addison, Brownwood, Corsicana, Mineral Wells, and San
Angelo.
Each project includes the following tasks:
· Data collection (including 24-hour machine counts, peak-hour turning movement
counts, travel time runs, intersection delay, existing timing studies, and
intersection inventories).
· Simulation of existing conditions using PASSER II, TRANSYT-7F, and/or
NETSIM.
· Calibration of computer simulations to ensure accurate representation of
observed conditions.
· Development of "Before" study (including travel time, calibration and annual
cost results).
· Development of optimum cycle lengths, patterns, and timing using PASSER II
and TRANSYT-7F.
· Preparation of timing sheets.
· Implementation and fine-tuning of pin settings and offsets into controllers.
· Evaluation of new patterns and timing results in an "After" study.

SCOPE OF SERVICES
The proposed engineering services will be sufficient to prepare an application for funds under
the Traffic Light Synchronization Program II, with only minimal, essential input from the City.
The grant application will be prepared for city submission as outlined by SDHPT's Grant
Application Procedures dated April 1991.
Barton-Aschman has reviewed the above procedures and proposes to complete the following
tasks, accordingly.
1. Meet with city staff to review selection criteria, identify potential projects, and to
determine available pertinent information.
2. Observe project locations or sections in the field; and collect appropriate travel time
and delay data to define operational characteristics (consistent with the required
Quality of Service Study Method).

3. Review traffic volume data available from the city and identify supplementary data, if
needed. Barton-Aschman will collect up to two (2) 24-hour counts if needed.
4. Determine in discussion with city, other selection criteria information needed for
application.
5. Contact local SDHPT District Office to secure supplemental information, if necessary
at locations on the state system.
6. Prepare grant application originals to consist of cover page and the following seven
attachments:
A. Standard Assurances
B. Project Area Maps
C. Description of Project
D. Quality of Service
E. Budget
F. Project Task Responsibility
G. Debarment Certification
7. Review completed application with City and modify if necessary.
8. Assist City in responding to questions from SDHPT, if they arrive during application

1. Three (3) copies of the completed grant application for review.
2. Six (6) final grant applications for SDHPT submission.
RESPONSIBILITY OF THE CITY
The City will provide the following to BA:
1. Proposed project(s)information.

FEE FOR SERVICES AND METHOD OF PAYMENT
The fee for completing the project will be based on our hourly rates for staff personnel,
current at the time of performance, for staff services rendered. The maximum fee and
expenses for completion of Tasks 1 through 8 will not exceed $1,656.00 without receiving
prior written authorization from the City. Attachment A gives the time and fee estimates on
an individual task basis for the proposed Scope of Services. Reimbursable expenses are also
given.
The fee for extra services, meetings, work sessions, and presentations (and work in addition
to the tasks indicated in the Scope of Services) will be billed separately based on our hourly
rates for staff time and expense.
Direct reimbursement for out-of-pocket expenses such as mileage, reproduction, etc., will be
billed at cost and will be added to the staff time costs incurred on the project.
Invoices will be submitted monthly and will indicate charges incurred during the preceding
month. Billings are due and payable within thirty (30) days of invoice date. A one and one-
half (1.5) percent carrying charge will be added each month to all past due accounts.
AUTHORIZATION
We are prepared to initiate work on this project upon receipt of a signed copy of this Letter
of Agreement. This proposal will remain valid for thirty days.
