1.0 INTRODUCTION /BACKGROUND rll. The purpose of this document is to summarize the data collection efforts, traffic signal timing optimization methodology, and results of a traffic signal
timing optimization project for the Town of Addison. Kimley-Horn and Associates, Inc. developed new, optimized traffic signal timing plans for the seventeen (17) intersections listed
below and illustrated in Exhibit A. Belt Line at Marsh Belt Line at Business Belt Line at Commercial Belt Line at Surveyor Belt Line at Runyon Belt Line at Midway Belt Line at Beltway
Belt Line at Addison .Belt Line at Quorum Midway at Spring Valley Midway at Hornet Midway at Proton Midway at Beltway Midway at Lindberg Midway at Dooley Marsh at Realty Spring Valley
at Greenhill The need for this project was significant. Intersections along Belt Line Road and Midway Road had not been retimed for eight to ten years. Traffic patterns and volumes within
the Town of Addison have been in constant flux over the last decade. Traffic volumes along Belt Belt Line Road and Midway Road are some of the highest in the Dallas-Fort Worth area.
Parts of the hardwireinterconnect system are inoperable and impractical to repair. This interconnect failure means the loss of coordination between traffic signals. Finally, the need
for coordinated timing plans within the Town of Addison is significant due to the Dallas /Fort Worth metropolitan area's (D/FW) designation as a non-attainment area. DIFW must conform
to acceptable pollutant standards within the next few years or risk severe sanctions. Traffic signal timing improvements are the most cost effective solution forreducing vehicle emissions,
delay, stops, and fuel consumption. One of the primary objectives of the project was to provide coordination between jurisdictions. As shown in Exhibit A, the cities of Carrollton, Dallas,
and Farmers Branch all have coordinated systems adjacent to the Town of Addison. The adjacent agency intersections, which were evaluated for inter-jurisdictional coordination, are listed

2.0 DATA COLLECTION The infonnation required to model existing conditions and develop optimized timing plans is extensive. The type of infonnation that was collected is highlighted below:
lI, • Number of traffic lanes per approach Assignment of traffic lanes Existing actuated timing plans (min and max greens, clearance intervals, etc ...) Existing coordinated timing plans
for adjacent jurisdictions Distance between intersections Speed limits Traffic volumes (24-hour counts and turning movement counts) "Before" and "after" travel time runs fI(Il, Traffic
Counts Two types of traffic counts, 24-hour recording machine counts and turning movement counts, were made by Kimley-Horn's data collection subconsultant (Metrocount). The machine counts
recorded the number of vehicles by direction in IS-minute increments. Each such count included one weekday of data. These directional counts are shown in Exhibit B. More detailed daily
count infonnation is illustrated in Appendix A. Accordingly, having traffic volume data on a daily basis, it is possible to determine the appropriate "time-of-day, day-of-week" schedule
for operation of the new timing plans. The turning movement counts were hand counted by observers. For each intersection approach, the observers counted the vehicles by specific movement
(i.e., left turn, straight through, or right turn). Data were tabulated by IS-minute increments and totaled by the hour. Turning movement counts were perfonned during the following time
periods on a typical non-holiday weekday: • AM Peak (6:30 AM -8:30 AM) • Off Peak (9:00 AM -11:00 AM) Noon Peak (11 :30 AM -1:30 PM) • PM Peak (4:30 PM -6:30 PM) Detailed turning movement
count data sheets are included as Appendix B. Travel Time Runs Both "before" and "after" travel time runs were made using the floating car technique during the time periods shown above.
The "before" runs were made prior to the implementation of the new signal timing to establish baseline conditions (vehicle speeds, delay, and number ofstops) and to detennine appropriate
progression speeds, areas where queue management is critical, and areas where recurrent congestion may affect progressive traffic movement. "After" travel time runs were made to evaluate
the degree of improvements in vehicle speeds, delay, travel times, and stops due to the implementation of optimized signal timing. Final Report -Traffic Signal Timing Project 3

rI i(r(I 3.0 NEW TIMING PLANS Coordinated traffic signal timing plans were developed for each of the project intersections for the AM, Off, Noon, and PM peak periods. These plans run
Monday through Friday from 6:30 AM to 11 :00 PM. Weekend plans run from 11 :00 AM to 7:00 PM on Saturday and Sunday. The development of timing plans for the Town of Addison had to consider
the incorporation of existing coordinated timing plans from the adjacent jurisdictions. Coordination between jurisdictions is impossible unless you have the cooperation of the other
jurisdictions and the cycle lengths of each system are the same. Fortunately, the cities of Carrollton, Dallas, and Farmers Branch supported the concept of inter-jurisdictional traffic
signal coordination, Unfortunately, all three agencies utilized completely different cycle lengths. Cycle Len2fhs The traffic signal cycle length in a coordinated system is the amount
of time to go from the -beginning of the main street yellow around to the beginning of the main street yellow. For a coordinated system to function properly, each intersection within
the system must have the same cycle length. The peak period cycle lengths of the adjacent agencies were noted as follows: • 144 seconds for Carrollton (Marsh at Country Place and Midway
at Keller Springs) • 160 seconds for Dallas (Belt Line at the Tollway) • 120 seconds for Farmers Branch (Midway at Alpha and Marsh at Beltway) After calculating the cycle length requirements
of the Addison intersections, evaluating the need for coordination, and discussing possibilities with the various agencies, we determined that the biggest benefits would occur with the
following coordination strategies: • Belt Line Road system to match the Dallas system • Belt Line at Trend to match Belt Line system (Carrollton modification) Midway at Dooley to match
Carrollton system Marsh at Beltway to match Belt Line system (Farmers Branch modification) Optimized Timing Plans Using the above coordination strategies, the timing optimization model
calculated preliminary timing for each intersection movement. This information was input in the field into each traffic signal controller. Individual intersection movement time lengths
and progression throughout the system were extensively reviewed. Improvements to the traffic signal timing plans were implemented and reanalyzed. 4.0 RESULTS In order to determine the
extent to which the new plans had improved traffic flow, travel time runs were once again made by Metrocount. These runs were made using "floating car techniques", i.e., the driver ofthe
test vehicle took care to drive with the pace of the other traffic. As the vehicle passed through each signalized intersection, the elapsed time was recorded. Also, the duration of stopped
time, if any, was recorded. The results of these travel time runs are highlighted in Exhibit C. Final Report -Traffic Signal Timing Project 5

the "Before" and "After" travel time runs by direction. The results show significant travel time reductions for each arterial during each time period in each direction. These results
were verified in the field with Town of Addison staff. A detailed summary of these results is provided in Appendix C. 5.0 OBSERVATIONS /RECOMMENDATIONS Throughout the course of the project,
a few important issues were noted for future reference. These issues and our recommendations, which are based on past experience and current standards, are noted below: • All traffic
signal controllers and traffic signal cabinets need to be upgraded. Most of this equipment has not been updated for over ten years. The controller is no longer in production. Spare parts
will eventually not be available. A good analogy is to visualize a 286 computer at each intersection. • IIII! \ • \\I\ The amount of Town staff dedicated to traffic signals is below
the industry standard of one technician per 20 to 30 traffic signals. The Town's one technician is only partly dedicated to traffic signals meaning that the Town cannot perform proactive
maintenance or operational improvements. Another staff member should also be trained in operation and maintenance of the traffic signals. This second individual would could assist in
daily maintenance and operational calls as well as provide back-up for vacations, sick-leave, and late night on-call shifts. A traffic signal system with intersection communications
needs to be installed. Without this improvement, Town staff will have to continue to manually reset the controller clocks on a weekly (sometimes daily) basis. This resynchronization
is required for optimized coordination. The benefits ofhaving this type of system include the following: Final Report -Traffic Signal Timing Project 6
r· ( • A precise timing relationship can be maintained at all times. The system periodically downloads a clock update to its local controllers, thereby assuring that each controller
is precisely "in step" with the desired timing plan. • Timing adjustments can be made remotely; an operator at the signal maintenance shop enters the change into the microcomputer and
then executes a download. • Most system malfunctions are reported automatically; the field master auto-dials. the shop's microcomputers and uploads an "alarm." The Town does not have
to wait for a motorist to complain to determine that the system is not working properly. In order to insure the longevity of the new timing plans, the Town of Addison should address
these issues in the near future. j( 6.0 ACKNOWLEDGEMENTS r( ,.'. Kimley-Hom acknowledges the support of Robin Jones and Charles Mitchell of the Town of Addison. They provided extensive
insight to the traffic needs of the Town and "went the extra mile" to facilitate the timing plan implementation and fine-tuning process. Final Report -Traffic Signal Timing Project 7

EXIllBIT A. ENGINEER'S SERVICES I. PROJECT DEFINITION, MANAGEMENT, AND CONTROL Kim1ey-Horn and Associates, Inc.. (KHA)shall perfonn the following Professional Services relative to the
optimization of signal timing for 17 intersections in the Town of Addison (TOWN). This Scope of Services shall hereinafter be referred to as "the Project." Project Definition. For purposes
of this Project the following 17 intersections in the TOWN shall be included: 1. Town ofAddison intersectionsto be included in signal timing: a) Belt Line at Marsh b) Belt Line at Business
c) Belt Line at Commercial d) Belt Line at Surveyor e) Belt Line at Runyon f) Belt Line at Midway g) Belt Line at Beltway h) Belt Line at Addison i) Belt Line at Quorum j) Midway at
Spring Valley k) Midway at Hornet 1) Midway at Proton m) Midway at Beltway n) Midway at Lindberg 0) Midway at Dooley p) Marsh at Realty q) Spring Valley at Greenhill 2. Other agency
intersections to be included in the model: r) Marsh at Country Square (Carrollton) s) Marsh at Beltway (Farmers Branch) t) Belt Line at Trend (Carrollton) u) Belt Line at Tollway NB
and Tollway SB (Dallas) v) Midway at Keller Springs (Carrollton) w) Midway at Alpha (Farmers Branch) x) Spring Valley at Proton (Farmers Branch) Timing plans for intersections shown
above in the Project Definition (subpart 2) will not be optimized, modified, or fine-tuned. However, existing coordinated timing plans, phasing, and turning movement counts ofthese intersections
will be added to the model. A. Project Meetings. Unless otherwise stated herein, it is assumed that all Project technical and review meetings will be held in the Addison Service Center.
It is agreed for budgeting purposes that up to six (6) meetings will be held relative to the Project, which is expected to have a total duration ofapproximately three (3) months. B.
Project Control. KHA will coordinate data collection and design efforts with TOWN staff and/or consultants working within or adjacent to the project limits. Project records will be Page
1 of6
) maintained throughout the duration of the project. One set ofthese records will be given to the TOWN upon the completion ofthe project. C. Project Schedule. KHA shall develop a project
schedule using the Microsoft Project software program. Deviations from the original schedule will be incorporated into the schedule and discussed with the TOWN. D. . ONOC. Throughout
the project, KHA senior staff will conduct quality reviews. These reviews will address the completeness and accuracy of traffic data collected and of the timing plans developed. ll.
DATA COLLECTION KHA will collect the following data: A. Turning Movement Counts. New turning movement count data will be collected and reduced for four (4) two (2)-hour time periods
at each Project intersection. Data will be tabulated by IS-minute increments, by approach direction (e.g., northbound, etc.), and by turning movement (e.g., left,· straight, or right).
In addition, the number of vehicles not being serviced on the first cycle will be counted every five minutes for the intersection of Belt Line and Midway. The time periods shall be defined
as follows: • AM Peak = eight (8) consecutive IS-minute periods (normally 6:30 AM to 8:30 AM) on a non-holiday Tuesday, Wednesday, Thursday, or Friday; • Noon Peak = eight (8) consecutive
IS-minute periods (normally 11 :30 AM to 1:30 PM) on a non-holiday Monday, Tuesday, Wednesday, or Thursday; • PM Peak = eight (8) consecutive IS-minute periods (normally 4:30 PM to 6:30
PM) on a non-holiday Monday, Tuesday, Wednesday, or Thursday; and • Off Peak = any eight (8) consecutive IS-minute periods between 9:00 AM and 11:00 AM on a non-holiday Tuesday, Wednesday,
Thursday, or Friday. It is understood that the beginning and ending times of the AM Peak, Noon Peak, PM Peak, and OffPeak counts may be adjusted based on the results ofrecording machine
count data. B. . 24-Hour Machine Counts. For up to 12 locations, new Monday-through-Friday recording machine count data will be collected and reduced. For each location and direction,
a minimum of twenty-four (24) hours of data will be recorded by IS-minute increments, beginning on or before 11 :00 PM on a Monday and ending on or after 1:00 AM on Friday. Counts will
not be made on holidays, during adverse weather conditions, or when school is not in session. Four additional counts will be made on Saturday. C. Travel Time Runs. Both "before" and
"after" travel time runs will be made using floating car techniques during the time periods shown in Section ILA above. The three routes to be included in these travel time runs include
Belt Line, Midway, and Marsh. The "before" 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. KHA will review recently
Page 2 of6
. ) ) completed travel time runs by TOWN staff for possible inclusion into the "Before" run database. . After the fine-tuning and adjustment of the new, optimized signal timing is in
place, the "after" runs will be made to document the degree ofimprovement. D. Initial Field Observation. Prior to the development ofnew signal-timing, KHA shall coriduct field observation
on each route during each time period. A traffic engineer with extensive experience in the development and implementation ofprogressive traffic signal timing plans shall perform such
observations. E. Photolog Summary. KHA shall photograph each approach of each signalized intersection. These photographs shall highlight the traffic signal hardware for each approach.
A copy of the photolog will be given to the TOWN upon completion ofthe project. F. Existing Timing Plan Review. TOWN personnel will download existing traffic signal timing information
from each of the controllers. This information will be reviewed and input into the timing model developed by KHA. Likewise, traffic signal timing information for the other local agency
controllers will also be input into the model. G. Verification of Intersection Geometries. For each Project intersection, KHA will verify the following elements of intersection geometries
and pedestrian accommodations that affect signal timing: . • The number of lanes on e.ach 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"); • Approximate street widths, crosswalk lengths, and grades; and • Existence of pedestrian signal indications
(i.e., "Walk" and "Don't Walk") and/or pedestrian actuation. ill. PRELIMINARY ANALYSIS. KHA will perform the following preliminary analysis: A. Adjust Count Data. Using information from
the traffic counts, KHA will make adjustments as necessary to ensure the reasonableness of the turning movement counts for each intersection. If any· adjustments are deemed necessary
the changes will be made upon conference with the TOWN. . B. 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, Noon Peak, PM Peak, and Off Peak time periods. For each control area, KHA will review the newly collected count data
to verify the number ofplans. C. Determine Control Area Boundaries. KHA shall use the following process to determine the optimum control area boundaries for timing plan purposes: • Review
traffic timing parameters of coordinated systems in adjacent cities; • Review the new and previously existing count data to determine similarities In volume fluctuation patterns; Page
3 of6
") • For each timing plan period (e.g., AM Peak, Noon Peak, PM Peak, and Off Peak), 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 opportunities for mutual coordination with existing intersecting systems and
systems in adjacent cities, KHA 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. Generally speaking, the need for coordination between any two signalized intersections is directly proportional to the traffic volume and inversely proportional
to the distance between the intersections. This relationship can be quantified mathematically by the "coupling index", where D = distance, V = volume, I = coupling index, and I = VfD.
The coordinatability factor calculated by Synchro™ 4.0 which is a modified version of the coupling index may be substituted for the coupling index. Wherever feasible and appropriate,
however, the overall control areas for this Project will be structured to achieve interlocking two-way progression, north-south and east-west. Accordingly, in those instances where adjacent
signals have essentially the same cycle length requirement, the presumption will be that they should be coordinated, irrespective of volume or distance. In those instances where different
cycle lengths are required, coupling indices will be computed for selected links to refine the initial control area configurations. D. KHA will prepare a technical memorandum that documents
the following: • Proposed control area boundaries, with discussion of factors which went into their determination (e.g., cycle length requirements, volume fluctuation patterns, and coupling
indices); • 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; • Before travel time data. KHA will meet to receive comments on the draft technical memorandum. KHA will incorporate review comments
and submit a final technical memorandum. Any changes that are agreed to at the review meeting will be documented in the minutes of the review meeting and will be incorporated into the
final report. IV. GENERATION OF TIMING PLANS A. Develop Controller Interval Timing. Based on approach speeds and intersection geometrics, KHA will develop the appropriate controller
interval timing for the yellow, all-red, and pedestrian clearance intervals will be calculated by KHA. This data will be provided in tabular (spreadsheet) format for TOWN review. After
receipt ofreview comments, this data will be finalized and submitted again in tabular format. Page 4 of6
) B. Initial Timing Plans. Making appropriate use of Synchro™ 4.0, PASSER II-90, PASSER ill-90, PASSER IV-94, and/or TRANSYT-7F, KHA will generate new signal timing plans. It is anticipated
that up to four (4) unique plans will be generated for all subsystems of the Project. This generally will consist of unique plans for the AM Peak, Noon Peak, PM Peak, and OffPeak time
periods. Progression bandwidths for all timing plans will be optimized to the maximum practical extent using dual leading left-turns. After this optimization is complete, the arterial
will be re-optimized allowing the 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). KHA will identify locations where a "yellow trap" condition would result because of a leading ''protected-permitted'' left-turn phase on the opposite approach. This information
will be provided to the TOWN and reviewed with them to determine the most appropriate appropriate method for eliminating the yellow trap condition. The [mal timing will make use of lagging
left-turns only at those locations where the yellow trap will not 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, KHA will discuss the characteristics of each plan and receive comments. KHA will then finalize each timing plan
to incorporate such comments. . This project will follow current Town of Addison requirements for traffic signal timing. C. Finalize Timing Plans. KHA will furnish the final timing plan
data in an electronic format for the 820A controllers. .. v. . TIMING PLAN IMPLEMENTATION AND FINE-TUNING A. Implementation Assistance. KHA will assist TOWN personnel during the implementation
of coordinated timing plans. A senior engineer will be available to download the new coordinated plans and respond to questions that may arise during the implementation process. B. Timing
Plan Fine-Tuning. When the new timing is operational, KHA will provide qualified staff members for on-site. fine-tuning assistance. During the course of this assistance, KHA will observe
the actual operation of the new timing plans and suggest adjustments to improve the operation. Each of the TOWN intersections will be observed during the AM, NOON, PM, and OFF peak periods,
It is assumed that TOWN persomiel will participate in this process, thereqy gaining familiarity with the timing plans. For budgeting purposes, it is mutually understood and agreed to
that no more than onehundred and thirty-two (132) man-hours will be expended under this contract for finetuning purposes. Page 5 of6
VI. FINAL REPORT A. Analysis of "Before" and "After" Results. KHA will update the model for the fme-tuning changes. The results from the final ("After") model runs will be compared with
the results from the "Before" study. Specific measures of effective which will be compared are vehicle delays, stops, fuel consumption, emissions, and travel times. B. Preparation of
Final Report. At the conclusion of the· Project, KHA will prepare a final report that will include the following: • The updated information originally provided in the technical memoranda;
and • Summary ofProject benefits as determined from an analysis of the "before" and "after" data. The following additional information will be provided in the appendix: . • Final signal
timing data along with time-space diagrams; and • "After" travel time runs. KHA will submit a draft fmal report for review and will subsequently meet to receive comments. KHA will then
submit the fmal report, incorporating the review comments. C. Presentation of Results. KHA will present the results of the project at one (1) Town Council meeting. Page 60f6
