TO: BOARD OF SUPERVISORS
FROM: J. MICHAEL WALFORD, PUBLIC WORKS DIRECTOR
DATE: September 12, 1995
SUBJECT: Consulting Services Agreement with Dowling and Associates
Project No. 4660-6X4144
Specific Request(s) or Recommendation(s) & Background & Justification
I. RECOMMENDED ACTION:
APPROVE a Consulting Services Agreement between the Contra Costa County Public Work
Department and Dowling and Associates.
II. FINANCIAL IMPACT:
Payment limit is $60,000. All costs will be provided through the Regional Traffic Signalization
Operations Program grant. The grant is administered by the Metropolitan Transportation
Commission. Therefore, no cost will result to the County.
III. Reasons for Recommendation and Background:
The Public Works Department applied for and received a grant for traffic signal upgrades
along the Pleasant Hill Road/Taylor Boulevard corridor. The grant provides for the selection
of a consultant to perform various studies and to then recommend timing changes and
synchronization of the signal system. The approval of the Consulting Services Agreement
would allow the consultant to begin such work.
IV. CONSEQUENCES OF NEGATIVE ACTION:
Failure to approve the agreement would result in forfeiture of the $124,500 grant received by
the Public Works Department.

Womscom AND DELIVERABLES
Task I - Review the Existing Roadway System
Purpose:
• Collect signal system data required for the study.
• Identify any special needs of project review team members.
Task Description:
1.1 Field Review
The Dowling Team will conduct a field review to identify field conditions relevant to
development of traffic signal coordination plans. Plans or "as-built" drawings will be used
as a reference for the field review. Where plans are available, the field reviewer will
confirm significant design features; features which have been changed will be noted. At
intersections where plans are not available, sketches of the intersections (constraint diagrams)
will be drawn showing geometric conditions such as channelized turn lanes, lane width and

length dimensions, where relevant, and unusual geometric features. Photographs will also be
taken to document field conditions and provide in-office reference for all intersections.
1.2 Information Gathering From Review Team
A meeting will be initiated at the beginning of the project to collect data required for
development of signal coordination plans. Essential information includes identification of
signal control equipment and signal phasing plans. Additional information that would be
useful includes "as-built" plans and contract specifications for installation of existing
equipment, signal timing cards, and any existing timing plans that may be in effect. It will
also be important to obtain information from the review team members regarding their
preferences on signal phasing (e.g. use of lagging left turns) and analysis methodologies to
be used for traffic operations analysis described under Task 4.
A letter will be sent to all project review team members in advance of the meeting to provide
a meeting agenda and project schedule, and to request participants bring information needed
for the project.
Products:
a. Sketch drawings and photo log of each intersection.
b. Summary of signal system data.
C. Summary of special needs of project review team members.
Task 2 - Collect Traffic Counts
Purpose:
• Provide basis for development of signal coordination plans.

Dowling Associates
Transportation Engineering - Planning • Research - Education
Task Description:
The Dowling team will collect hourly directional counts at two locations for the "time period
from Thursday through Sunday, inclusive. The preferred locations for these directional
counts is near the north and south ends of the project corridor. These counts will provide
data for identification of peak periods during the weekend and for determining when each
plan should be in effect.
Turning movement counts at each of the fourteen project intersections for the weekday
morning, midday and evening peak periods will be conducted during typical weekdays:
Tuesday through Thursday. The weekend peak period turning movement counts will be
conducted during the peak period identified by the hourly directional counts.
Products:
a. Turning movement counts for weekday morning, midday, evening and weekend peak
periods.
b. Hourly directional counts at two locations from Thursday through Sunday.
Task 3 - Conduct Travel Time Studies
Purpose:
To document the effectiveness of the signal coordination plans.
Task Description:
Travel time runs will be conducted for the morning and evening peak hours using the
floating-car technique. Six runs will be made in each direction for each peak period for the
before and after project conditions. Travel times will be recorded separately for each
jurisdiction's signals (three segments) for each run. Summary data will be provided showing
the travel time for each segment and the travel time for the entire corridor.

Products:
a. Average travel times for the morning and evening peak hours for before and after
project conditions.
Task 4 - Develop and Present a List of Possible Alternatives
Purpose:
• Identify operational or geometric changes expected to improve traffic flow.
• Provide early review and feedback on possible system modifications.
Task Description:
To identify potential operational and/or geometric changes that may improve traffic flow, the
Dowling team will analyze the level of service of all intersections using the TRAFFIX
software package. TRAFFIX is a program, developed by Dowling Associates, which
incorporates the latest (1994) Highway Capacity Manual techniques along with other
methodologies for analyzing traffic operational efficiency in a single easy to use package.
Modifications to system intersections will be tested using the methodology preferred by each
member of the project review team for their jurisdiction. Service improvements may include
restriping to add a left turn lane, changes in signal phasing, or other modifications.
Service improvement alternatives identified in the traffic operations analysis will be tested
against the physical constraints at the intersections to determine which alternatives may be
the most practical given funding and schedule constraints. (It is possible that some possible
improvements may not be recommended for implementation under this project but may
deserve future consideration). The Dowling team will present applicable improvement
options to the review team along with an approximate cost estimate and cost-effectiveness
assessment.
Products:
a. Summaries of traffic operations analysis for existing conditions and potential
alternatives.
b. Cost estimates and cost-effectiveness assessment for potential alternatives.

Task 5 - Develop Traffic Signal Coordination Plans
Purpose:
• Develop traffic signal coordination plans specially tailored to the Pleasant Hill Road /
Taylor Boulevard project corridor.
Task Description:
5.1 General
The Dowling team will develop signal coordination plans for the following time periods:
- Weekday AM peak period
- Weekday PM peak period
- Weekday noon period
- Weekend peak period
Timing plans will be developed using the TRANSYT-717 optimization model, using the
QUICK-71' program for coding and editing of model data. Timing plan development will be
performed in two steps. First, the TRANSYT-7F model will be calibrated to represent
actual field conditions on Pleasant Hill Road and Taylor Boulevard. The second step will
involve optimizing traffic signal timing.
The Dowling team recommends consideration of zones within the arterial system which
would allow application of half cycle signal timings, or some other partial cycle where traffic
demand is low and delay might otherwise be excessive. Use of shorter cycle times in some
instances may minimize delay without serious sacrifices in signal progression. This might be
particularly true where signals are separated by significant distance.
The Dowling team will present all recommendations to the review team and solicit feedback
at strategic decision points.
5.2 Calibration
To calibrate the TRANSYT-717 model, traffic data will be collected at the major intersections
along the corridor and compared against the TRANSYT-717 default values. Saturation flow
rates, volume/capacity ratios, percent stopping and queue lengths will be compared to field
observations at congested intersections for the weekday PM peak period. If discrepancies are
7
Dowling Associates
Transportation Engineering - Planning - Research • Education
discovered, the model inputs will be checked for accuracy and adjusted to replicate actual
field conditions.
5.3 Optimization
A combination approach will be directed toward optimizing traffic signal coordination plans.
The first element of our approach is to maximize the bandwidth. Second we will minimize
stops, delay, fuel consumption, and queue spillover.
The Progression Opportunities model (PROS) contained in the latest version of TRANSYT-
7F provides for bandwidth optimization. PROS has an inherent advantage over traditional
maximum bandwidth programs such as PASSER II and MAXBAND. PROS considers both
through bands and short term progression opportunities. Because PROS looks for
opportunities to provide travel through two or more adjacent intersections at the desired
progression speed, it is much more flexible than the traditional through bandwidth programs.
Using PROS alone, however, has been shown to sacrifice minimizing stops, delays, and fuel
consumption.
Using the disutility index in TRANSYT-7F results in significant reductions in stops, delay,
and fuel consumption. However, reliance on the disutility index does not result in a
maximum bandwidth.
Using PROS as a function of the TRANSYT-7F disutility index will result in the most
optimum timing plans. The combination approach has been proven by the results from
studies around the country and has been confirmed by our experience with the cities
participating in the 1993 FETSIM program in California. The Dowling team has had
extensive experience in using the PROS model since its release in 1993. As part of our
FETSIM services, we recommended the use of PROS to many cities. The results from using
the PROS versus the traditional approach based on minimizing the disutility index were
significant.
A preliminary set of signal coordination plans will be submitted for review and comment.
Based on comments received from the project review team, Dowling Associates will revise
the preliminary signal coordination plans, if necessary.

Products:
a. Computer printout of calibrated simulation runs for existing conditions.
b. Coordination plans for weekday morning, noon, evening and weekend peak periods.
C. Time Space Diagram showing progression opportunities.
Task 6 - Develop a Final Plan
Purpose:
• Fine tune signal coordination plans
• Develop a plan for implementation.
Task Description:
The Dowling team will develop a plan for implementation that involves preparation of timing
sheets in a format required for installation of controller settings. The timing sheets will be
prepared in the format required for each jurisdiction. Each jurisdiction will be responsible
for actual installation of signal timings.
The Dowling team will develop a recommended schedule of operation for each signal
coordination plan. The recommended schedule will be based on the directional machine
counts described under Task 2. We will evaluate when each timing plan should be in effect
and when the signals should be set to operate free or set to flashing operation, if appropriate.
The Dowling team will also recommend a schedule for implementation of signal equipment
and timing plans. Coordination of timing plan implementation with equipment installation
activities will be an important element of a successful implementation plan. Dowling
Associates staff will review traffic operation in the field and recommend fine tuning
adjustments to the installed timing plans, if necessary. We will perform simulation runs
using TRANSYT-7F with the fine tuned timing plans.
Products:
a. Timing sheets for each intersection.

d. Final signal coordination plans with fine tuned adjustments.
Task 7 - Prepare Draft and Final Reports
Purpose:
• To document project activities
Task Description:
Interim products identified in the previous tasks will be combined into draft and final reports.
The reports will contain a summary of the study and study results including a description and
graphic of the network, project assumptions, simulation run results, final optimization plan
results, subsystems identified, and implementation plan. The report will clearly identify
improvements in corridor travel time, energy savings, and estimates of improvements in
vehicle emissions. Five (5) copies of the draft report will be provided for review. Based on
review comments, the report will be revised and ten (10) copies of the final report will be
submitted.
Products:
a. Draft Report (five copies)
b. Final Report (ten copies)
Task 8 - Prepare PS&E
Purpose:
• Develop bid documents for procurement and installation of equipment necessary to
provide WWV coordination.
• Define any required physical modifications for contractor installation.
10
Dowling Associates
Transportation Engineering Planning Research Education
Task Description:
The consultant team will inventory all existing traffic signal controllers and hardware to
ensure compatibility with WWV receivers. Time base coordination with the use of WWV
technology is relatively reliable and is easy to maintain; however, older traffic signal
controllers such as the Multisonics 911 cannot be coordinated with WWW receivers.
Equipment upgrades and options will be investigated and presented to the project team.
Recommendations will be made regarding the most cost-effective upgrade option. Equipment
upgrades, costs and availability will be investigated to ensure the project will be completed
on schedule and within budget.
Plans will be developed showing physical modifications to intersections recommended and
approved in Task 4, and providing details for installing WWV receivers and any other
hardware that may be required. Plans and specifications will be incorporated into County bid
documents and submitted for review. One set of revisions will be incorporated into the final
bid package and resubmitted for bidding. Cost estimates will also be provided. The
Dowling team will assist in reviewing bid proposals and will assist in assessing which
equipment will provide the most reliable performance.
Products:
a. Alternatives for signal equipment upgrade with an assessment of cost-effectiveness.
b. Preliminary and final plans, specifications, and estimates.
