D. Project Administration and Control It is understood and agreed that the Engineer's contract is
with the County and that all services shall be performed under the direct supervision of the
Director. It is also understood and agreed that the Cities of Irving and Coppell and/or
TxDOT's designated representative may communicate directly with the Engineer for the
purpose of providing technical direction relative to traffic signal timing matters which affect
their respective jurisdiction. In the event of discrepancy between the review comments of the
various reviewers and agencies, it is mutually understood and agreed that the Director will
provide final direction to the Engineer.
II. SIGNAL TIMING OPTIMIZATION
A. PrelimiM Analysis The Engineer will perform the following preliminary analysis:
1. Field Observations Prior to the development of new signal timing, the Engineer shall
conduct field observation on each route and during each time period of analysis. Such
observation shall be performed by a traffic engineer with extensive experience in the
development and implementation of progressive traffic signal timing plans.
Initial travel time runs will be made prior to the development of the new signal timing to
establish baseline conditions (speeds, delay, and number of stops) and to determine
appropriate progression speeds, areas where queue management is critical, and areas where
recurrent congestion may affect progressive traffic movement. Additional runs will be
made once the new optimized signal timing is implemented to assist in the fine- tuning and
adjustment of the new signal timings.
2. Verification of Intersection Geometrics For each Project intersection, the Engineer will
verify the following elements of intersection geometrics and pedestrian accommodation
that affect signal timing:

• The number of lanes on each approach and the required or permitted usage of each lane
(i.e., "left only "; "left or straight "; "straight only "; "straight or right "; "right only "; or
"left, straight, or right ", etc.) ;
• Approximate street widths, crosswalk lengths, and grades; and
• Existence of pedestrian signal indications (i.e., "Walk" and "Don't Walk ") and/or
pedestrian actuation.
• Proposed geometric improvements at each signalized intersection.
3. Adjust Count Data Using factors developed from the recording machine counts, the
Engineer will estimate the vehicular volumes for those intersection approaches for which
actual Saturday turning movement counts were not made. The Engineer will present the
data collected and calculated at a Technical Review/Progress Meeting.
4. Determine Number of Timing Plans Required Based on an assessment of existing
recording machine count data, it is anticipated that most areas should have unique timing
plans for the AM Peak, AM Off Peak/Noon Peak, PM Off -Peak, PM Peak, Late Evening
Off -Peak and Saturday time periods. For each control area, the Engineer shall review the
newly collected count data to verify the number of plans.
5. Coordination with Adjacent Cities Along Belt Line Road the opportunity exists to
provide some degree of coordination across Irving and Coppell at these city's mutual city
limits. The Engineer will confer with the staffs of those cities.:
• The existing control areas and cycle lengths by time of day in the areas contiguous
with Irving and Coppell; and
• The extent, if any, to which the other city would be willing to modify the control
areas and/or the cycle lengths to enhance the opportunities for coordination across
the mutual boundary with Irving and Coppell.

6. Determine Control Area Boundaries The Engineer shall use the following process to
determine the optimum control area boundaries for six (6) unique timing plans:
• Review the new and previously existing count data to determine similarities in volume
fluctuation patterns;
• Review proposed signalized intersections that may be pending or scheduled for
construction in the immediate future within the studied signal systems.
• For each of the six (6) timing plan periods (e.g., AM Peak, AM Off- Peak/Noon, PM
Off -Peak, PM Peak, Late Evening Off -Peak, and Saturday), determine approximate
cycle length requirements for key intersections, which shall include all diamond
interchanges and all arterial/arterial intersections.
• Based on the above, and taking into consideration (1) the intersections groupings
currently defined by the City of Irving or Coppell's signal systems and (2) the
opportunities for mutual coordination across city limits, the Engineer will make an
initial division of the overall Project area into control areas. This information will be
presented in map form for review and subsequent interactive discussion.
7. Finalize Cycle Lengths and Control Area Boundaries The Engineer shall identify which
signals should be coordinated; determine need, time, and duration of peak period timing
plans using the following techniques:
• Conduct a variability analysis of traffic demand through the day and week; and/or
• Use of a numeric coupling index analysis using vehicle link demand to distance
ratios, and/or
• Use of computer software coordinability factors, grouping of natural isolated
location cycle lengths; and/or other

• Methodologies utilized in this analysis however such methods must be acceptable
to the City jurisdictions. Coordination recommendations shall identify locations
which are to perform as a coordinated system by time -of -day. Each timing plan
shall include start and duration time and shall include the peak traffic demand
periods.
8. Technical Memoranda For each control area, the Engineer shall prepare a Technical
Memorandum which documents the following:
• Proposed control area boundaries, with discussion of factors which went into their
determination (e.g., cycle length requirements, volume fluctuation patterns,
coupling indices, etc.);
• Proposed coordination, if any, across city limits;
• Proposed cycle lengths; and
• Preliminary measures of effectiveness.
In addition, the following information will be provided as an appendix to the technical
memorandum:
• Traffic counts, both raw data and adjusted values;
• Initial travel time data.
The Engineer will meet with the County and representatives of the local jurisdictions to
receive comments on each such technical memorandum during the scheduled Technical
Review/Progress Meetings (paragraph I. A.). The technical memorandum shall be
formatted to facilitate its incorporation into the Project's Final Report. Changes which are
agreed to at the Technical Review/Progress meetings will be documented in the minutes of

the review meeting and will be incorporated into the Final Report in accordance with the
following Article III. Deliverables.
B. Generation of Timing Plans
lans
1. Determine Controller Interval Timing Based on approach speeds, trrafic volumes and
existing intersection geometrics and/or other CMAQ geometric improvement , the
Engineer will determine the appropriate controller interval timing (minimum green,
passage, yellow, all -red, walk, pedestrian clearance, MAX I, etc.). This data will be
provided in tabular (spreadsheet) format for existing geometry and for proposed CMAQ
geometry. After receipt of review comments, this data will be finalized and submitted in
tabular format in accordance with the following Article III. Deliverables.
2. Generate Timing Plans Making appropriate use of PASSER II -90, PASSER III -90, or
PASSER IV -94, TRANSYT7 -F, Syncro, or other County approved software, the
Engineer will generate new signal timing plans. It is anticipated that six (6) unique plans
will be generated for all subsystems of the new signal system. This will generally consist
of unique plans for the AM Peak, AM Off- Peak/Noon, PM Off -Peak, PM Peak, Off -Peak
and Saturday time periods. In addition, a "Late Evening Off - Peak" plan will be developed
for each subsystem using traffic volumes derived as follows:
• Using the recording machine counts, the ratio of the Late Evening Off -Peak
volume levels to the Noon and/or PM Off -Peak volume levels will be determined;
and
• The Late Evening Off -Peak turning volumes will be estimated by applying this
ratio to the counted Noon or PM Off -Peak turning volumes.
Progression band widths for all timing plans will be optimized to the maximum practical
extent through variation of the signal phase sequence (i.e., a particular left turn phase may

be "leading" during one timing plan but lagging during one or more other timing plans).
At locations where a "yellow trap" condition would result because of a lagging "protected -
permitted" left turn phase on the opposite approach, the Engineer will confer with the
Texas Department Of Transportation (TxDOT) or the local jurisdiction's staff to determine
the feasibility of their implementing "Dallas" left -turn phasing to eliminate the yellow trap.
This will include the Engineer considering vehicle driver sight distances at these
locations. The final timing willuse Dallas left -turn phasing or other means that will not
allow a yellow trap to occur.
Each timing plan will include a cycle length, offset, and split. The plans, along with a
computer - generated time -space diagram, will be submitted for review. At a subsequent
review meeting, the Engineer will discuss the characteristics of each plan and receive
comments. The Engineer will finalize each timing plan to incorporate such comments in
accordance with the following Article III. Deliverables.
3. Finalize Timing Plans The Engineer will furnish the final timing plan data in generic
form, i.e., cycle length in seconds, split times in both seconds and percent of cycle, and
offset in both seconds and percent of cycle. Also included will be minimum green, amber,
all red, max phase length, walk, and dont't walk intervals. Offsets will be referenced to the
beginning of the first major street green phase (i.e., the "barrier "). The Engineer will
prepare controller time sheets for each intersection from the generic timing plans. These
will be prepared based on the individual input needs of the different controllers.
Timing data will be entered by City personnel; and it is assumed that the Engineer's role
relative to timing plan implementation will be limited to responding to questions that may
arise during the implementation process.
C. Timing Plan Fine - Tuning When the new timing is operational, the Engineer will provide
qualified staff members for on -site fine- tuning assistance. During the course of this assistance,

the Engineer will observe the actual operation of the new timing plans and suggest minor
adjustments to improve the operation.
For intersections in Irving and Coppell, Irving and Coppell personnel will participate in this
process, thereby gaining familiarity with the timing plans and with the fine- tuning process.
The Engineer will provide up to three (3) person weeks of on -site fine tuning for the
intersections in Irving and Coppell.
Actual timing adjustments will be entered by City personnel.
If the final timing plans produced by the Engineer in Task II.B are not input by the City
personnel within fourty five (45) calendar days, Task II.0 shall be considered complete.
D. Final Report At the conclusion of the Project, the Engineer will prepare a Final Report in
accordance with the following Article III. Deliverables which will include the following:
• The updated information originally provided in the technical memoranda;
• Summary of Project benefits as determined from an analysis of the initial and final data
analyses; and
• The following additional information, provided in the appendix:
• Final signal timing data (in spreadsheet format) along with time -space diagrams; and
• Travel time runs
• Software input values used in the timing analysis for each timing plan.
The Engineer will submit a draft Final Report for review and will subsequently meet to review
comments during one of the Technical Review/Progress meetings. The Engineer will then
submit the Final Report, incorporating appropriate review comments in accordance with the
following Article III. Deliverables.
