AGENDA ITEM WORDING:
Discussion and Direction Regarding Work Order No. 03 to Complete Additional Data Collection Runs
for the 2023 U.S. 1 Arterial Travel Time and Delay Study ("ATTDS") in Segments 13-24, as approved
by the Monroe County Board of County Commissioners ("BOCC") at the BOCC's February 21, 2024,
regular meeting.
ITEM BACKGROUND:
The U.S. 1 Arterial Travel Time and Delay Study("ATTDS") is performed biennially to monitor the
Level of Service ("LOS") on U.S. Highway 1 ("U.S. 1"). The study is conducted for concurrency
purposes,pursuant to Monroe County Comprehensive Plan Policy 301.1.2 and Monroe County Land
Development Code Sections 114-2 and 114-200. Monroe County's adopted overall and segment LOS
on U.S. 1 is LOS "C,"represented by a median speed of 45 miles-per-hour("mph").
On November 8, 2023, the Monroe County BOCC considered the Draft 2023 Arterial Travel Time&
Delay Study. The Draft 2023 ATTDS reported an overall LOS D on U.S. 1 with a median speed of 44.7
mph, but indicated that all segments within unincorporated Monroe County currently operate at a LOS
C or better. The report noted that Traffic Signal Delays and Construction Delays were
significantly longer in 2023 than in 2021, and the Monroe County BOCC's traffic engineering
consultant,AECOM, suggested re-collection of data in 2024 on at least some segments,where
construction delays were excessive, and/or the Keys COAST project and signal retiming is
underway and may improve traffic flow.
At discussion-and-direction Item M2 on the published agenda of the BOCC's regular 8 November 2023
public meeting ("Discussion and direction on the 2023 U.S. 1 Arterial Travel Time and Delay Study and
the Preparation of the Biennial Assessment of Public Facilities Capacity Report"), the BOCC voted to
approve this recommendation for re-collection of data in 2024.
On February 21, 2024, the BOCC approved Work Order No. 03 to Complete Additional Data
1955
Collection Runs for the 2023 U.S. 1 Arterial Travel Time and Delay Study ("ATTDS") in Segments 13-
24 (scope of work attached), based on BOCC direction given at the November 8, 2023 regular meeting.
The Work Order agenda item indicated that the Florida Department of Transportation("FDOT") had a
traffic signal retiming project planned for February 2024 in these segments, and that the additional runs
will be performed in March 2024, following the FDOT traffic signal retiming project.
Following the February 21, 2024, approval of the work order, staff was informed that the FDOT
signal retiming project has been delayed until approximately June, 2024.
Per the adopted Arterial Travel Time & Delay Study methodology, data collection is to occur during the
peak traffic season, which ends in April. Therefore, 2024 data collection will be done before the signal
retiming has occurred.
Given that the signal re-timing project has been delayed, and the signal re-timing was a factor in the
BOCC's November 8, 2023, decision to re-collect data in 2024, staff is requesting that the BOCC
approve/maintain its prior decision to re-collect data and proceed with Work Order No. 3.

SCOPE OF SERVICES FOR WORK ORDER NO. 3
US-1 Arterial Travel Time and Delay Study 2024
Monroe County, Florida
A. INTRODUCTION
The Monroe County Planning Department requested that a Travel Time and Delay Study
be conducted in certain segments that experienced delays due to roadway construction
and/or traffic signals during the 2023 Travel Time and Delay Study. Some segments with
signals will also be included as part of this study due to the upcoming FDOT signal
retiming effort that is expected to start in February/March of 2024. Based on these
considerations, the travel time runs will be conducted from Marathon (segment 13) to
County Line Sign (segment 24).
B. SCOPE OF SERVICES
Tasks 1 — 4: Travel Time and Delay Studies
Using the floating car method, the Consultant will record travel time, speed, and delay
data for the segments from 13 to 24. Data will be recorded by date, day of week, time of
day and direction.
The study will be conducted over 14 days within the four-week period in March 2024.
The study will consist of 14 round-trip runs, sampling each day of the week twice.
The study will employ the staggered schedule of departure times previously approved
by the US 1 Level of Service Task Force Team, so as to record peak hour conditions in
as many different locations as possible.
Task 5: Study Report
The study results will be summarized in a report, including a series of tables and graphs.
The travel time and speed data will be used to determine LOS and reserve capacity.
In addition, a statistical analysis of the mean, median, standard deviation, and range of
speed recorded for each individual segment and for the overall US-1 corridor will be
provided. Excess roadway capacities and deficiencies in capacity will be determined and
reported in accordance with the latest US 1 Level of Service Task Team Methodology.

Discussion and direction on the 2023 U.S. 1 Arterial Travel Time and Delay Study and the preparation
of the Biennial Assessment of Public Facilities Capacity Report.TIME APPROXIMATE OF 11:00
A.M.
ITEM BACKGROUND:
The U.S. 1 Arterial Travel Time and Delay Study ("ATTDS") is performed biennially by the County's
traffic consultant (AECOM) to monitor the Level of Service on U.S. Highway 1 ("US 1"). This
professional traffic engineering study is conducted for concurrency purposes, pursuant to Monroe
County Comprehensive Plan Policy 301.1.2 and Land Development Code Sections 114-2 and 114-200.
The Monroe County Comprehensive Plan and Land Development Code require that all development
and redevelopment taking place within the unincorporated County do not result in a reduction of the
level of service requirements, including transportation facilities. The Comprehensive Plan and Land
Development Code include a Level of Service Standard of"C" (45 mph) for U.S. 1.
This LOS standard is used within the County's Concurrency Management System to review
development proposals and ensure that the transportation facilities needed to serve development will be
in place when the impacts of the development occur. Concurrency must be satisfied at the time a
development permit is issued; at the time a certificate of occupancy; or through a binding contract or
agreement for the necessary facility and/or service improvements or proportionate share contribution.
To determine the Level of Service ("LOS") on U.S. 1, the County's professional traffic engineering
consultant conducts an established systematic traffic monitoring program, developed by the U.S. 1 LOS
Task Force, to monitor traffic volumes and travel speeds of U.S. 1. It is important to note that the U.S. 1
LOS Task Force developed a unique methodology to assess level of service for the Florida Keys to
cover both its overall arterial length from Key West to the Florida mainland, and 24 roadway segments
delineated, based on an average travel speed formula.
1
1965
Along with completing the systematic traffic monitoring program, the Comprehensive Plan and Land
Development Code ("LDC") Section 114-2(b)(3) directs professional staff to submit a Biennial
Assessment of Public Facilities Capacity Report ("PFCR") to the BOCC to identify the capacity of
available public facilities. For this report Monroe County utilizes the U.S. 1 Arterial Travel Time and
Delay Study to document the road/transportation available capacity and areas of marginal or inadequate
facility capacity.
The LDC further directs that the County shall not approve applications for development in areas of
Monroe County that are served by inadequate facilities identified in the Biennial Assessment of Public
Facilities Capacity Report, except the County may approve development that will have no reduction in
the capacity of the facility or where the developer agrees to increase the level of service of the facility
to the adopted level of service standard, through:
• A binding executed contract is in place at the time the development permit is issued which
provides for the commencement of the actual construction of the required facilities or provision
of services; or
• An enforceable development agreement guarantees that the necessary facilities and services will
be in place with the issuance of the applicable development permit. An enforceable development
agreement may include, but is not limited to, development agreements pursuant to section
163.3220, F.S., or an agreement or development order issued pursuant to Chapter 380, F.S., or
• The proportionate share contribution or construction is sufficient to accomplish one or more
mobility improvement(s) that will benefit a regionally significant transportation facility.
The Draft 2023 ATTDS reports that the overall LOS for the entire length of U.S. 1 has fallen
from LOS C to LOS D (44.2 mph), and there is no reserve capacity for additional trips. According
to the policies and regulations in the Monroe County Year 2030 Comprehensive Plan and Monroe
County Land Development Code, this would mean that County may not permit new development,
other than single family homes, unless the proposed development's traffic impact is mitigated.
The Draft 2023 ATTDS does indicate that all individual segments within unincorporated Monroe
County currently operate at a LOS C or better. Within unincorporated Monroe County, two (2)
segments operate at a LOS C: Long Key (Segment 16) and Cross Key (Segment 24).
The 2023 ATTDS further indicates that two (2) segments within unincorporated Monroe County
decreased in LOS as compared to the 2021 ATTDS: Stock Island (Segment 1) which fell from an LOS
A to a LOS B; and Big Pine Key (Segment 10) which fell from a LOS A to a LOS B as compared to the
2021 ATTDS.
Note regarding Segment 1 (Stock Island):AECOM has included an alternative reserve capacity chart
with alternate LOS and reserve capacity analysis for Stock Island (Segment 1) in Appendix G of the
draft report. The first reserve capacity chart indicates LOS B for Segment 1, with an overall U.S. 1
median travel speed of 44.2 mph (LOS D). The second, alternative reserve capacity chart, which the
BOCC may choose to utilize, indicates LOS A for Segment 1, with an overall U.S. 1 median travel
speed of 44.7 mph (LOS D), and includes the following note: This table is based on all travel time Nuns
except 3 SB Nuns in segment 1 (Stock Island)from 3-14-23 to 3-16-23. These 3 SB Nuns were excluded
as the average travel speeds were very low (4-7 mph) and were considered as outliers. The overall
travel speed is 44.7 mph as compared to the previous page table that has an overall travel speed of
44.2 mph and is based on all travel time runs. Both reserve capacity charts are included as
attachments to this agenda item for reference and consideration.

1966
Within unincorporated Monroe County, fourteen (14) segments saw no change in LOS between the
2021 and 2023 ATTDS: Boca Chica, Segment 2; Big Coppitt, Segment 3; Saddlebunch, Segment 4;
Sugarloaf, Segment 5; Cudjoe, Segment 6; Summerland, Segment 7; Ramrod, Segment 8; Torch,
Segment 9; Bahia Honda, Segment 11; 7-Mile Bridge, Segment 12; Long, Segment 16; Tavernier,
Segment 22; Key Largo, Segment 23; and Cross, Segment 24. Additionally, both segments within the
City of Marathon (Marathon, Segment 13; and Grassy, Segment 14) and one segment within saw no
change in LOS between the 2021 and 2023 ATTDS.
Within unincorporated Monroe County, the LOS increased from a LOS C to a LOS B in Duck Key
(Segment 15) as compared to the 2021 ATTDS.
A summary of the LOS Study by segment within Monroe County is attached to this agenda item
(Average Travel Speeds and Levels of Service). Those segments at LOS C are highlighted in yellow.
Those segments with no reserve capacity (all of which are within the incorporated area of Islamorada)
are highlighted in dark orange (LOS D and LOS E).
The Monroe County Land Development Code provides, at Section 114-2, that:
1. U.S. 1 shall have sufficient available capacity to operate at LOS C for the overall arterial length
and the 24 roadway segments of U.S. 1, as measured by the U.S. 1 Level of Service Task Force
Methodology, at all intersections and roadway segments.
2. Development may be approved, provided that the development in combination with all other
permitted development will not decrease travel speed by more than five percent (501o) below LOS
C.While development may be approved within 5% of LOS C, the proposed development shall be
considered to have an impact that needs mitigation. Development mitigation may be in the form
of specific improvements or proportioned shared contribution towards improvements and
strategies identified by the County, and/or FDOT to address any level of service degradation
beyond LOS C and/or deficiencies.
Within the incorporated city of Marathon, both segments operate at a LOS of C or better: Marathon,
Segment 13, operates at a LOS A; and Grassy Key, Segment 14, operates at a LOS C.
Within the incorporated area of Islamorada, Village of Islands, Lower Matecumbe (Segment 17)
improved from LOS C to LOS B as compared to the 2021 ATTDS and Upper Matecumbe (Segment
19) saw no change from the 2021 ATTDS, remaining at LOS E.
Within the incorporated area of Islamorada, Village of Islands, three(3) segments decreased in LOS:
Tea Table, Segment 18, dropped from LOS A to LOS B; Windley, Segment 20, dropped from LOS D
to LOS E; and Plantation, Segment 21, Dropped from LOS C to LOS D.
In 2009, Islamorada adopted a Comprehensive Plan amendment to address U.S. 1 Level of Service
standards for transportation facilities, as follows:
Policy 2-1.21: Adopt Level of Service (LOS) Standards Pursuant to the U.S. 1 Level of Service Task
Force. Islamorada, Village of Islands hereby adopts the following level of service (LOS) standards for
roadways, pursuant to the methodology developed by the U.S. 1 Level of Service Task Force for
3
1967
analyzing LOS in Monroe County:
1. The level of service on U.S. 1 shall be maintained within 5% of LOS C as measured on an overall
countywide basis not dependent on any single road segment, using the measured median travel
speed from the annual report of public facilities capacity.
2. For all other roadways for which the Village is responsible, the Village hereby adopts a minimum
LOS standard of D as measured by peak hour traffic volumes at all intersections, including but
not limited to all intersections with U.S. 1.
[Policy 2-1.2.2 deleted pursuant to Ordinance No. 09-23]
Policy 2-1.2.4: Prevent Development Resulting in Additional Trips on Deficient U.S. 1 Without
Mitigation. The Village shall deny development permits for development that would result in additional
trips on U.S. 1 upon exhausting the 5% below LOS C allowance authorized by the U.S. 1 Task Force
Methodology as measured on an overall countywide basis not dependent on any single U.S. 1 segment,
unless the impacts of the proposed development can be mitigated for its proportionate share of required
transportation concurrency improvements pursuant to Section 163.3180 F.S.
Under Monroe County Comprehensive Plan Policy 301.2.3 ,if the overall LOS for US 1 falls below
the LOS C Standard, then no additional land development will be allowed unless mitigation
measures are implemented.
Per the County's professional transportation engineering consultant, AECOM, who conducted
the study:
Roadway widening is a typical mitigation measure (or capacity improvement) used by most agencies.
However, in Monroe County, road widening (specifically along U.S. 1) is restricted by the adopted
Comprehensive Plan Policies to preserve and protect the fragile ecological conditions. There are other
remedies that could be explored and evaluated to improve the traffic flow and capacity along U.S. 1.
Some examples include:
• Upgrade the traffic signal infrastructure and/or signal timing at signalized intersections
along U.S. 1 to enhance traffic flow. FDOT has programmed a signal retiming study along
US 1 in Monroe County,which is expected to start in early 2024.
• Provide or improve transit service or other multi-modal transportation alternatives.
The Monroe County Transit Department is in the process of initiating studies/projects to improve
transit service
• Implement active traffic management and Transportation System Management & Operation type
improvements, which include real-time monitoring of traffic flow and implementing measures to
address traffic congestion. Video cameras at some intersections are being installed through the
ongoing Keys COAST project by FDOT, which will help monitor traffic flow.

• Add turn lanes at strategic locations to improve roadway capacity.
• Implement access management improvements (consolidate driveways/access points, modify
median openings, etc.) to reduce interruptions to U.S. 1 traffic.
• Provide and/or improve frontage roads to reduce the impacts to U.S. 1 traffic flow.
• Improve local roads to minimize U.S. 1 being used as a local street for short trips.
• Do not install new traffic signals along U.S. 1, if a safe and/or less restrictive alternative (such as
indirect left-turns, a roundabout, etc.) can be provided to accommodate traffic movements.
• Conduct speed studies on selected segments of U.S. 1 to confirm if the current posted speed
limits are appropriate and modify, if necessary.
The U.S. 1 Transportation Master Plan has identified several locations for improvements. It is
recommended that follow-up studies be conducted at those locations to evaluate the feasibility of
implementing improvements (such as the ones listed above or from the Master Plan) to enhance traffic
flow.
This is the first Travel Time and Delay Study conducted after all COVID-19 related restrictions have
been lifted and more people appear to be traveling. The traffic data collected as part of this study,
indicates higher volumes as compared to 2021 traffic volumes. The increased volumes may have
impacted travel speeds.
Table 4 of the Draft 2023 ATTDS (attached to this agenda item) summarizes the "delay events"within
the 2023 data and provides a comparison to delay data from the 2021 ATTDS. As explained on Pages
18-20, Signal Delays and Construction Delays were significantly longer in 2023 than in 2021:
• Tra ff c signals resulted in a total delay of 2 hours, 18 minutes and 12 seconds in 2023, as
a.
compared to 1 hour and 8 seconds in 2021... The last signal retiming study that included 16
traffic signals along US 1, was performed by FDOT in 2019. It is possible that a new signal
retiming study at the above segments/locations may help reduce the signal delay, which may
improve the overall US 1 Level of Service.
• Construction delays accounted for 4 hours 29 minutes and 55 seconds during the 2023 study, as
compared to 2 hours 14 minutes and 56 seconds construction delay during the 2021 study...
There was significant increase in construction delay during the 2023 study as compared to 2021
study. For example, emergency water main 2023 — US 1 Arterial Travel Time and Delay Study
Monroe County repairs at MM 84 affected travel time runs on March 8 and March 9; only SB
direction of travel was allowed at a time on US 1, while the NB traffic was diverted to Old Hwy
(parallel to US 1) and afterwards merged back to US 1;flagger operations were used for traffic
management.
It is important to note that, if adopted, the 2023 ATTDS will not be used for development review until
the Biennial Assessment of Public Facilities Capacity Report ("PFCR") is adopted, which will be
scheduled for a future BOCC meeting.

STAFF RECOMMENDATION:
Staff requests the BOCC provide direction and approval on the following items for the 2023 Arterial
Travel Time and Delay Study(ATTDS):
1. Stock Island (Segment 1) LOS:
A. Use of Stock Island (Segment 1) analysis including 3 SB travel runs identified as outliers by
AECOM (Segment 1 LOS B; Overall median travel speed=44.2 mph); or
B. Use of Stock Island (Segment 1) analysis excluding 3 SB travel runs identified as outliers by
AECOM (Segment 1 LOS A; Overall median travel speed= 44.7 mph).
2. AECOM suggests re-collection of data in 2024 on at least some segments, where construction delays
were excessive, and/or the Keys COAST project and signal retiming is already underway and may
improve traffic flow. Once data is updated, ATTDS and PFCR could be updated mid-2024.
3. Dependent on decisions above:
A. Approve and Utilize 2023 ATTDS for PFCR(development applicants must identify mitigation);
Next study in 2025 (data collection March '25; results adopted October '25). Development must
mitigate until October 2025.
B. Continue to Utilize 2021 ATTDS (2023 data affected by excessive construction delays) for PFCR;
Next study in 2025.
C. Approve and Utilize 2023 ATTDS for PFCR(development applicants must identify mitigation);
Data updates in March 2024; results August 2024. Development must mitigate until mid/late 2024.
D. Continue to Utilize 2021 ATTDS (2023 data affected by excessive construction delays) for PFCR;
Data updates in March 2024; results August 2024.
