SCOPE OF SERVICES
Task 1 - Preparation for initial meeting -
The study team will prepare for an initial meeting with the City of Fort Collins traffic
engineering staff. The team will prepare an agenda to follow and a list of items that
need to be addressed during the meeting.
Task 2 - Philosophy Meeting with City Staff
The study team will meet with the City of Fort Collins traffic engineering staff to
review existing practices and philosophy. The team concurs with traffic engineering
staff that each city has a philosophy of signal timing that they would like to maintain.
We envision a full day meeting to discuss these and other issues. The meeting should
be held at a location where everyone can concentrate on the issues.
David Hook, Dan Cronin, and Allen Albers will attend the meeting. Following are
examples of the types of questions that might be discussed:
• What is the City's Philosophy on the range of cycle lengths to be used?
• How should bicycles and pedestrians be accommodated?
• What is the city's philosophy on preemption?
• How does the cityfeel about leading vs. lagging left turns?
• Should heavier volume movements be favored for progression?
• What is the City's philosophy regarding travel speeds to be used?
• How should over -capacity intersections be treated?
• How much time should be given to side streets?
At this meeting the group will also discuss signal timing software. Most all available
software packages have been used by at least one member of the study team. Each
one has it's own ease of use, embedded philosophy, and results. The study team will
be prepared to discuss the various packages and lead the group into an agreement as
to which will be used.
The final part of the meeting will be to develop a schedule to complete the signal
timing effort. Hook Engineering places a strong emphasis on meeting project
schedules. The team will identify milestones and key dates that need to be met. The
group will also identify the level of effort needed by city staff to meet schedule.

Task 3 - Obtain Data from City, Collect Saturation Flow Rates
The City is underway collecting much of the needed data for the study. They City
will also be responsible for providing:
• Initial Travel Time and Delay Studies
• Link Travel Speeds
• Intersection Geometrics
• Signal Phasing
• Existing Timing
• Existing Link Volumes (with diurnal variation)
These data will be provided to the study team. The team will review these data for
consistency and reasonableness.
The City will also collect weekend peak turning movement volumes and road -tube
ADT volumes during the early part of September. These volumes will be at strategic
locations with high traffic volumes. The study team will use these volumes to
develop weekend timing plans.
The study team will collect saturation flow rate (SFR) studies at key intersections
within the City of Fort Collins.
Task 4 - Develop Timing Plan Periods, Coupling Analysis, Progression Priorities and
Progression Speed.
The existing daily traffic counts will be reviewed to determine where logical breaks
may occur throughout the day. The city currently has a plan describing what time of
day plans are implemented. However, as the city has grown, spreading of the peak
periods may have occurred. The study team will review the average daily traffic
volumes to determine if the existing time periods need to be adjusted.
A coupling index analysis is a methodology used to determine logical breaks for
signal timing zones. The coupling index is similar to Newton's theory of gravity and
follows the following form:
Index = Volume
distance
The higher the index, the more likely two signals should be tied together. The longer
the distance, the smaller the need for signals to be tied together. This formula has
been used throughout the U.S. and provides a good indication of where logical breaks
in the system should occur. Within these zones, the cycle length can be optimized to
Fort Collins Comprehensive Signal Timing Scope of Services Page 2
provide maximum progression. With a city the size of Fort Collins, we envision
approximately three to five zones. These zones will be reviewed with city staff.
The team will also review the data to determine which direction of traffic should
receive priority during the various time periods. Many jurisdictions tend to favor the
heavy commuter traffic for progression priority but some try to balance progression in
two directions.
Progression speed will be determined by reviewing speed limits and the results from
the before travel time and delay studies.
Task 5 - Code Data Files for Progression Program
As data are gathered, the study team will code the data into the selected progression
program. The following timing plans will be developed:
• AM Peak Plan
• Midday Plan
• PM Peak Plan
• Offpeak Plan
• Weekend Peak Plan
Task 6- Run Progression Program
Once the data are entered into the signal timing program, the program will be run to
produce the timing plans. The results will be portrayed in progression diagrams for
each progressed roadway. Several progression diagramming programs are available
which provide easy -to -read outputs.
Capacity analysis will also be provided at key intersections. The capacity analysis
together with the progression diagrams will be reviewed by the study team. The team
will evaluate the diagrams and look for opportunities to improve progression. This
will occur in an iterative fashion until the final draft plans are developed.
One effective method of reviewing the proposed timing is to compare it with the
existing timing. The proposed splits for a particular intersection should not be
radically different than the existing splits. If there are large discrepancies, the
intersection should be carefully reviewed to determine the reason for the major
change.
Once the timing plans have been developed, they will be provided to the city for
implementation.
FortCollins Comprehensive Signal Timing Scope of Services Page 3
The Saturday peak hour timing plan will be developed after the data has been
collected. It is anticipated this effort will occur in early September after the college is
back in session.
Task 7 - Implementation of Timing Plans
The city staff will code the timing plans into their central computer system. Prior to
this step, the team will work out a methodology by which the tinning plan is provided
to the city. Care needs to be taken that phases are not inadvertently switched. The
team will work with city staff to develop forms, spreadsheets or other methods to
make the implementation by the city easy and straightforward.
Task 8 - Fine -Tuning of Timing Plans
The study team knows that the development of good timing plans is only part -way to
the finished product. Once implemented, the routes must be driven to "fine-tune" the
timing.
One of the most common examples for the need for fine-tuning occurs where large
volumes of traffic are entering the traffic stream between signalized intersections.
These vehicles typically arrive at the downstream signal during the red phase. If the
beginning of green is not modified, the platoon arrives at the signal at the beginning
of green but must slow down because of these queued vehicles. Providing an earlier
green of just a few seconds can greatly reduce the amount of slowing incurred by the
platoon.
It is anticipated that the fine tuning will occur "on the fly". As adjustments are
needed, they will be called in to the person operating the central computer system.
After the plan has had a chance to be implemented, the route can be driven again to
see the effect of the change.
The study team has shown a high level of effort for this task because we know that
fine tuning is a necessary and important step in the process.
It is not necessary for the coding, running, implementing and fine-tuning of these
plans to occur all together for each time period. Once one time period is complete, it
will be implemented while the coding and running of the other time periods is
occurring.
Task 9 - Before /After Analysis
After all timing plans have been implemented and fine-tuned, the city will perform
after travel time runs of the various routes. These after travel time runs will be used
along with the before travel time runs to show improvements to the overall system.
