the event’s negative impact in safety and/or mobility
Examples of special events that require a permit include:
A. Air & Sea Shows
B. Renaissance Festivals
C. Marathons
11
C. Signal Retiming for Safety The Traffic Operations office is responsible for the implementation of the FL-SHSP. The district
believes that signal retiming process, due to its potential for enhancing traffic safety and
improving traffic flow, is instrumental in addressing the emphasis areas of the FL-SHSP,
specifically intersection crashes.
The primary objective of signal retiming is to improve the safety and mobility of the street
system by processing traffic through intersections safely and efficiently. A traffic signal that is
properly designed and timed can be expected to reduce the frequency and severity of certain
crash types.
As part of this assignment, the consultant shall complete the following five steps consistent with
the procedures and guidelines outlined in the FDOT Traffic Engineering Manual, MUTCD,
FHWA Traffic Signal Timing Manual, and ITE Traffic Signal Timing Manual. Although these
steps indicate the typical signal timing process, the consultant shall develop signal timing plans
that are consistent with the policies, procedures and preferences of the respective signal
maintaining agencies.
The five distinct steps that define the signal timing development process are:
1 – Project Scoping
The project scoping is a key component of signal timing development. During this step, the
consultant team shall establish the following items:
a. Objectives Common objectives based on signal timing policies include reducing the number and
severity of congestion related crashes, reducing stops, delay, and travel time for a
corridor. During the project scoping period, the consultant shall also identify any known
traffic related issues. The identification of these issues may be the result of public
comments, staff observations, or known discrepancies with established policies. Once
these issues, if any, are identified, the consultant shall develop objectives for the specific
signal retiming project. Reducing the number and severity of congestion related crashes
shall be the primary objective of all projects developed through this contract.
b. Standards and Procedures The consultant shall adhere to the applicable procedures and standards contained in the
current edition of MUTCD as well as FDOT standards and those followed by the signal
maintaining agency with jurisdiction over the project location. The procedures and
standards shall be confirmed as part of the scoping process. The standards identify
parameters used for the timing of change and clearance intervals, actuated timing
settings, pedestrian timing, signal operation plans and phasing changes (such as
‘protected+permissive’ to ‘protected+only’ left turn phase, right turn overlap phase etc).
c. Control Sections The consultant shall identify logical groups (control sections) of signals to be included in
the timing process. The concept of sections is an important one. Typically, every
intersection in a section changes to a new timing plan at the same time of day. Each
12
intersection in a section likely operates in the same control mode—manual, time of day,
or traffic responsive. The control section boundaries are selected in a manner that will
minimize the need for interaction with the signals in adjacent sections. Changes to
control sections, if any, shall be, limited to those that can be implemented with the
equipment already in the field.
d. Performance Measures As the project scope is defined, performance measures must be selected to evaluate the
success of the retiming effort. The consultant shall include expected crash/injury severity
reduction, travel time, stops, delays, queue lengths, numbers of cycle failures, average
speeds and the percent time that intersections are congested as the performance
measures.
e. Number of Timing Plans The consultant shall at a minimum develop five distinct signal timing plans (i.e., for the
AM peak, mid-day peak, PM peak, day time off peak patterns and nighttime) for typical
weekdays, unless otherwise directed by the signal maintaining agency. In addition to
time-of-day plans, separate plans for weekdays, weekends or even specific days (such as
Friday in a high weekend travel area) may be warranted based on variation in travel
patterns and volumes. The consultant shall also determine the hours in which each
timing plan is to be operated.
2 – Data Collection
The data typically can be categorized as: traffic characteristics, traffic control devices,
intersection geometry, and crash history. The consultant is expected to collect the following data
as part of this step:
a. Crash Data The consultant shall analyze the crash data for the latest three-years available to identify
discernible crash patterns. The consultant shall also develop collision diagrams
intersection/ corridor using any automated crash mapping tool. Such automated tool
shall be presented to the FDOT project manager for approval prior to utilizing it for any
project. The consultant shall also develop and implement a QA/QC process for
automated collision diagrams.
At a minimum the consultant shall create the following histograms and tables as part of
the crash analysis:
Histograms
Crashes by type
Crashes by contributing cause
Crashes by time of day
Crashes by lighting condition
Crashes by surface condition
Crashes by weather condition
Crashes by day of the week
Crashes by month of the year
Crashes by age group at fault
Crashes by alcohol/drug involvement
13
Tables
High crash spots
High crash segments
Crash summary by type
Crash summary by contributing cause
Crash summary by location
b. 24-Hour Weekly Volume Profiles The weekly traffic volume profiles are an important element in the data collection effort
and should be collected at critical locations along the corridor. Critical locations are
those that govern the traffic characteristics of the corridor.
c. Turning Movement Counts Intersection turning movement counts shall be collected for representative traffic
periods. The traffic counts shall include a count of all vehicular traffic at the intersection,
as categorized by intersection approach (i.e., northbound, southbound, etc.) and
movement (i.e., left-turn, u-turns, through, or right-turn movement), pedestrians, and
vehicle type (including transit). If heavy vehicles are significant (i.e. more than 2%), the
vehicular count should be further categorized by vehicle classification. The presence of
special users at the intersection (e.g., elderly pedestrians, school children, bicyclists,
emergency responders, etc.) should also be documented.
d. Vehicular Speed Data on vehicular traffic speed should be gathered, as needed, to identify the approach
speeds to the intersection. This is especially important in determining the signal phasing.
Traffic speeds are especially important when considering controller parameters
influenced by detectors (for example, extension of green, time before reduction etc).
e. Travel Time Runs The consultant shall conduct travel time runs to record delay, stop, and running time
data. Such data can be used to calibrate the base analysis model and to compare the
corridor operations before and after the new timings are implemented.
f. Condition Diagram The consultant shall develop a scaled condition diagram to depict relevant geometric
and traffic control data (such as number of lanes, lane width, lane assignment, turn bays,
pedestrian crosswalks, vehicular and pedestrian signal heads, speed limit signs, phase
sequence, use of overlaps, and signal timing settings etc.).
g. Field Review Typically, the consultant shall conduct field reviews during AM peak, PM peak, off-peak
periods on a typical weekday and weekend at the signalized intersections and of the
subject corridor. The key elements to consider are location and operation of signal
equipment, intersection geometry, signal phasing, intersection operations, vehicle
queuing, adjacent traffic generators, preemption requirements (for trains, draw bridges
and emergency vehicles), posted speed and/or free flow speed.
14
h. Existing Signal Timing The consultant shall obtain the existing signal timing sheets from the local maintaining
agency to in order to develop a base analysis model. Key information from the existing
signal timing includes phase sequence, yellow and all-red intervals, pedestrian walk and
flashing don’t walk intervals, minimum green, and detector settings. Additionally, if the
intersection is operating in coordination, then the cycle length, splits and/or force-offs,
offsets, and reference phases should be obtained from the existing signal timing.
i. Intersection Analysis The consultant shall conduct an analysis to determine a reasonable signal phasing for the
prevailing conditions, evaluate the need for coordination, identify traffic signal control
mode of operation, verify detection design and to evaluate basic signal timing
parameters to determine the settings that will operate as a part of the timing plan.
3 – Model Development
The consultant shall utilize the FDOT approved computer-based tools are to calculate and
evaluate signal timing. Since many of these tools assume the presence of under-saturated
conditions, it is important to recognize their capabilities and limitations. The requirements for
developing timings for saturated and under-saturated conditions should be considered as the
model is developed. The consultant should consider the following elements:
• Establish a “standards and conventions” document (i.e., file naming, map settings, base data parameters, analysis settings) that provides the user with consistency through the retiming process;
• Review the plan development in levels or stages to ensure efficiency;
• Coordinate with the respective signal maintaining agencies; and
• Include quality assurance and quality control measures.
a. Data Input The consultant shall establish a base network utilizing computer models such as
Synchro, PASSER, TRANSYT-7F, TEAPAC etc. for the study time periods (i.e., morning,
midday, p.m., etc.). The typical data used in the model include lane geometry, link
speeds and distances, phase numbering, left- and right-turn phasing, existing signal
timing (i.e., yellow and all-red intervals, pedestrian walk and flashing don’t walk
intervals, minimum green, and detector settings), controller type, and coordinated
reference phases. Field observations should be compared with the traffic operation
results for each time period in the model. A review of the calibrated model shall be
performed prior to moving forward with the timing plan development analysis.
b. Analysis The consultant should utilize the following steps, which are typically used on the base
network for each time period to select a cycle length, evaluate intersection and system
operations, and identify the best plan based on the objectives of the study:
15
• Cycle Length Selection Cycle length selection should reflect local policies and users of the system. The
cycle length for the subject time period is determined based on the performance
measures that have been identified for the system.
• Cycle Length Refinement – Intersection Analysis Once a cycle length is selected, the volume-to-capacity ratios, movement splits,
minimum splits, and vehicle queues should be evaluated at each of the subject
intersections for the two to four cycle lengths identified for further refinement.
This analysis allows the consultant to assess if the cycle length will meet specific
objectives of the study.
• Corridor Refinement - System Analysis After the analysis is complete, a system analysis of the subject corridor or
network should be completed to provide an analysis of:
o Vehicle progression along the corridor
o Intersection-to-intersection interaction
o Left-turn operations
Simulation The consultant shall use the simulation program to compare the selected performance
measures resulting from the new timing with the measures produced by the existing
timing or other cycle lengths. In this way, the potential effectiveness of the new timing
can be evaluated.
4- Draft Timing Plans
After the cycle lengths are evaluated, the intersections and system analyzed, and the
timing plans compared, a preferred timing plan should be selected. The consultant shall
submit the draft timing plans for review to the Department and the local signal
maintaining agency.
5- Final Timing Plans
Once the Department and local signal maintaining agency have completed their review
and the comments have been incorporated into the draft timing plans, the timing plans
are ready to be deemed final.
Task products A signal retiming plan will be deemed completed after a safety report, signed and sealed by a
professional engineer registered in the State of Florida, has been submitted and approved by the
department. The safety report at a minimum shall include:
• Methodology, findings and recommendations
• Input and output data files of the computer model
• Hard copies of Signal phasing and timing plans
16
• Copies of the correspondence with the local signal maintaining agency, meeting minutes etc.
• Benefit-Cost Analysis: Three types of B/C analysis shall be performed (*)
• Net Present Value (NPV) Analysis: Three types of NPV analysis shall be performed (**)
• Expected Crash Reduction Table based on the latest 3-year crash data
The consultant shall submit four hard copies and two CD-ROMs (or DVDs) with PDF of the
report and the files used to develop report in their native format (for example Synchro files,
word documents, excel tables, jpeg files etc).
(*): Benefit –Cost
Type 1:
Type 2:
Type 3:
(**): Net Present Value
Type 1: NPV based on crash reduction benefit
Type 2: NPV based on operational benefit
Type 3: NPV based on combination of crash reduction and operational benefit
The consultant shall utilize a service life of three years for the purpose of benefit/cost and NPV
analysis.
D. Structural Analysis Typically, as part of retiming process, revisions to signal phasing may result in modifications to
signal head configuration, thereby increasing the load due to additional signal heads. In such
cases, the department may assign this task to the consultant to verify the structural integrity of
the signal poles due to the additional loads. The consultant shall utilize FDOT approved analysis
software packages (such as “Atlas” for strain poles and “Mast Arm Program” for mast arm
supports) for conducting the structural analysis. If available, the department will provide access
to as-built plans and/or survey files to the consultant. If such information is not available or if
the study location is on a local roadway, the consultant shall be responsible for collecting
pertinent data necessary to perform the structural analysis.
1. Task products A structural analysis task will be deemed completed after a technical report, signed and sealed
by a professional engineer registered in the State of Florida, has been submitted and approved
by the department. The technical report at a minimum shall include:
• findings and recommendations
• calculations
• Input and output data files of the computer model
• Hard copies of structural analysis worksheets
17
The consultant shall submit four hard copies and two CD-ROMs (or DVDs) with PDF of the
report and the files used to develop report in their native format (for example computer model
files, word documents etc).
E. Road Safety Audits The Traffic Operations office is responsible for the implementation of the FL-SHSP. The district
believes that RSAs, because of their proactive nature and the low-cost/high value nature of their
recommendations, are instrumental in addressing the emphasis areas of the FL-SHSP.
In general, RSAs aim to answer the following two questions:
1. What elements of the road may present a safety concern: to what extent, to which road
users, and under what circumstances?
2. What opportunities exist to eliminate or mitigate identified safety concerns?
The goal of an RSA is to develop recommendations that enhance safety, while minimizing
impact, if any, on traffic flow. As part of this assignment, the Consultant shall complete the
following steps consistent with the procedures and guidelines outlined in the FDOT MUTS
Manual, MUTCD, HSIP, AASHTO, and FHWA RSA guidelines:
1. Identify project or existing road to be audited.
2. Select RSA team. The consultant team must provide a qualified and multidisciplinary
team of experts suitable for the specific RSA to be conducted – each RSA will likely
require the participation of different areas of expertise. While in the ideal RSA some of
the expertise is provided by the local agency and/or the Department, there may be
occasions in which these agencies are unable to provide the necessary expertise. For
these cases, the consultant team shall have access to experts within the necessary fields
of expertise. Typical fields of expertise necessary to conduct an RSA are:
a. Road safety specialist. The road safe specialist shall act as the leader of all RSAs.
As the RSA team leader, the road safety specialist shall sign and seal the final
RSA document – the road safety specialist shall be a licensed engineer in the
State of Florida
b. Traffic operations engineer
c. Road design engineer
d. Local contact person
e. Other areas of expertise. Some of the areas of expertise that may be required in
some RSAs may include (this is not intended to be a comprehensive list):
i. Human factors
ii. Maintenance
iii. Enforcement
iv. First response
v. Pedestrian & bicycle treatment
vi. Transit operations
vii. ITS
18
3. Conduct a pre-audit meeting to review project information. This meeting shall
bring together the project owner, the design team (if any) and the audit team to discuss
the context and scope of the RSA and to review all project information available.
4. Office review of crash data and other available information. This step aims to
help identify areas of safety concerns. The RSA team should restrict its comments to
those issues having a bearing on the safety of road users. Comments may be either
specific to a particular location or broad-based. Issues related to aesthetics, amenities,
or congestion should also be commented upon if they lead to less-safe conditions
5. Perform field reviews under various conditions. For typical RSAs, at least 3 field
reviews ought to be performed: one during night time, one during the daytime peak
period, and one during day-time off-peak period. The number/time of field reviews may
be modified if the RSA study location justifies it. The objectives of the field reviews are:
a. Gain insight into the project or existing road
b. Verify/identify areas of safety concerns
6. Conduct audit analysis and prepare report findings. As a result, the safety issues
are identified and prioritized and suggestions are made for reducing the degree of safety
risk. Suggestions to enhance safety are to be prioritized using a Cartesian plane where
the X axis represents “feasibility”, and the Y axis represents “value”. RSA suggestions
should be appropriate to the state in the RSA and the elements being examined (ex., the
suggestions of a construction phase RSA would be different than those made in a
preliminary design RSA). The RSA results are then succinctly summarized in the formal
RSA report.
7. Present audit findings to project owner, design team, RSA steering
committee, or Safety Review Committee. The audit team will orally report the key
RSA findings to the project owner, design team, RSA steering committee, or Safety
Review Committee in order to facilitate the understanding of the RSA.
8. Record/Prepare Formal Response. The consultant team will summarize the
feedback provided by the project owner, design team, RSA steering committee, or the
Safety Review Committee to each safety issue/recommendation listed in the RSA report.
The Consultant team shall also be prepared to conduct RSAs of any of the following types:
1. Pre-construction road safety audits
a. Preliminary design road safety audits
b. Detailed design road safety audits
2. Construction Road Safety Audits
a. Pre-opening road safety audits
3. Post-Construction Road Safety audits
a. RSAs of existing roads
The members of the RSA team shall have demonstrated excellent command of the MUTCD and
familiarity with the Department’s Local Agency Participation (LAP) program.
It is expected that many of the recommendations made on post-construction RSAs would
involve pavement marking & signing enhancements. The consultant team shall have a
19
demonstrated ability and experience interpreting the MUTCD and creating pavement marking &
signing plans.
It is also expected that, occasionally, RSAs may recommend relatively high-cost safety
enhancements (ex., installing a new signal, installing/upgrading lighting, etc). Should an RSA
take place on a non-State Road, it is also possible that the local agency having jurisdiction over
the road may not have available the funds necessary to implement the recommendation. In
these cases, the consultant will be required to explain to the local agency the Department’s LAP
program.
1. Task products An RSA will be deemed completed after the following submittals are received and approved by
the Department:
1. RSA report. In general, the RSA report shall follow the following sample outline:
a. Introduction
i. Scope and purpose of the RSA
ii. Identification of project stage or existing road and items reviewed and not
reviewed

Cartesian plane
d. Formal statement. This is a concluding statement signed by the RSA team
members indicating that they have participated in the RSA and agreed or reached
consensus on its findings. The RSA team leader – the Road Safety Specialist –
who is required to be a licensed engineer in the State of Florida, shall sign and
seal the final report.
2. Crash summary tables. Each submission of the draft and the final technical
memorandum shall be submitted with the supporting crash summary tables. The crash
summary tables shall be developed using a spreadsheet compatible with MS-Office Excel
2007 and submitted to the Department in an electronic format.
2. Performance time When a single Road Safety Audit is issued in a task work order, the Consultant shall be provided
15 calendar days to conduct the RSA, submit a first draft to the Department, and make the
20
presentation of findings. The calendar days begin counting on the day the task work order is
issued.
The Department will prioritize the RSAs whenever multiple ones are issued in the same task
work order. The consultant, however, shall have enough qualified staff to simultaneously
conduct up to two RSAs
3. Format of Submittals All submittals, drafts and final document, shall be submitted to the Department in the following
manner, unless directed otherwise by the Department’s project manager:
1. Three (3) Hard copies (i.e., print), and
2. Electronic formats, which are:
a. pdf, and
b. the documents’ native format (ex., MS-Word, MS-Excel, etc).
F. Safety Review The Traffic Operations office is responsible for supporting the Department’s resurfacing,
reconstruction and rehabilitation (3R) program by developing a Safety Review for each project.
The purpose of this study task is to identify significant crash patterns and recommend actions
aimed at enhancing safety on locations that are programmed for 3R projects.
Under this task, the Consultant shall be responsible for:
1. Obtaining and analyzing all data necessary for the performance of the Safety Review.
The data shall include, but is not limited to:
a. The scope of the 3R project, if available
b. The department high crash lists – spot and segment
c. Crash data for the most recent 3 years available, from the following sources:
i. Department’s crash database
ii. Databases maintained by other agencies (ex., cities, counties, law
enforcement agencies, etc)
2. Meeting with local government representatives/officials and groups of concerned
citizens, if any, and document any safety concerns they may have
3. Analyzing crash data and identifying discernible crash patterns. At a minimum the
Consultant shall create the following graphs and tables for analysis:
a. Graphs:
i. Crashes per study year
ii. Crashes by type
iii. Crashes by contributing cause
iv. Distribution of crashes by locations of interest (ex., signalized, non-
signalized intersections, median openings, ramp, etc)
b. Tables
i. High crash spots
ii. High crash segments
iii. Collision summary by type
21
iv. Collision summary by contributing cause
v. Crash summary by location – assigning the rows to the locations of
interest, and the columns to the crash types, and highlighting crash
patterns that need further study
4. Conducting a field review during a peak hour (to be determined by the Consultant based
on the period where most crashes occur) and identify probable causes for the crash
patterns identified
5. Preparing a technical memorandum containing the findings of the crash data review,
interviews with local officials, and the probable causes for the crash patterns identified
6. Recommending, for each crash pattern identified, if an additional study needs to be
conducted.
1. Task products: This task will be deemed completed after the following submittals are received and approved by
the Department:
Final Technical memorandum. Prior to submitting the final technical memorandum, the
Consultant shall submit the document as a draft. If changes need to be made, the
Department will request a modified draft. The final technical memorandum shall be
submitted only after an acceptable draft, which generates no comments from the
Department is submitted. It is expected that the number of drafts submitted to the
Department will vary based on the quality of the submittal. The final technical
memorandum shall contain the name and contact information of the Consultant’s
engineer who managed the task.
Crash summary tables. Each submission of the draft and the final technical
memorandum shall be submitted with the supporting crash summary tables. The crash
summary tables shall be developed using a spreadsheet compatible with MS-Office Excel
2007 and submitted to the Department in an electronic format.
2. Performance time When a single safety review is issued in a task work order, the Consultant shall be provided 15
working days to conduct a Safety Review and submit a first draft to the Department. The
calendar days begin counting on the day the task work order is issued.
The Department will prioritize the Safety Reviews whenever multiple Safety Reviews are issued
in the same task work order. When this occurs, the Consultant shall submit the first draft of the
highest priority Safety Review within the first 15 working days while the first draft for the second
Safety Review, in terms of priority, shall be provided seven working days later – that is, within
the first 22 working days. This same seven working day increment shall be applied for each
additional Safety Review assigned.
Should the Department provide the Consultant comments on a Safety Review’s first draft, the
Consultant will be provided five (5) additional working days to submit a second draft.
22
Should the Department have comments on the second draft, or in any other subsequent draft,
the Consultant will be given three (3) extra working days to implement the comments and
submit a revised draft.
3. Format of submittals All submittals, drafts and final document, shall be submitted to the Department in the following
manner, unless directed otherwise by the Department’s project manager:
3. Three (3) Hard copies (i.e., print), and
4. Electronic formats, which are:
a. pdf, and
b. the documents’ native format (ex., MS-Word, MS-Excel, etc).
G. In-house support services At the Department’s request, the Consultant shall make available the services of any of the
positions identified in the “personnel” section of the scope of services. When in-house support
services are required, the Consultant will be compensated for hours on-the-job.
1. Potential in-house tasks The following table lists some of the tasks that may be assigned to the Consultant as in-house
support services. The table also indicates the type of position that would be expected to perform
this task:
In-house task Position Fatal crash reviews Engineer in training Draw collision diagrams Technician Retrieve crash data Technician Draw existing condition diagram Technician Draw proposed condition diagram Technician Develop maintenance task work orders Technician / engineer in training Crash analysis Engineer Operational analysis Engineer Field reviews and field measurements Technician / engineer in training / engineer Others as needed Depending on the task assigned
2. Use of field overhead Whenever the Department requests the services of a single position on a full time basis (40
hours per week) for any period longer than 21 working days (typically equivalent to one calendar
month), the fee shall be calculated using the Consultant’s field overhead.
3. Related in-house support costs The Department expects that the employee provided by the Consultant for in-house support
services will need the continued support from the home-office. For instance, the Consultant’s
home office is expected to make periodical reviews of the employee’s performance and job
satisfaction, provide training opportunities, and assist him/her with other administrative tasks
(ex., preparation of timesheet, expense reimbursement documents, etc).
23
Thus, the Department will allow the Consultant to bill 3 project manager hours and 3 clerical
hours for every 21 work days labored by each employee providing in-house support services.
Whenever in-house support services are provided for a period briefer than 21 days, project
management and clerical hours shall be prorated to the nearest half hour.
4. Work load limits for in-house support employees Whenever an employee is assigned to provide full time (i.e., 40 hours per week) in-house
support services for the Department, the Consultant Project Manager shall limit the employee’s
work load to the 40 hours he/she is working for the Department, unless approved in writing by
the Department’s project manager.
Such a limitation in the work load of employees providing in-house support services will help
ensure that:
employee burnout is avoided
employee operates at peak performance
employee’s attention is focused entirely on the Department’s work
FDOT receives high quality services
5. Billing for in-house support services The Consultant shall invoice the Department on a monthly basis for in-house support services,
unless otherwise approved by the Department’s project manager. The invoice must be preceded
by a progress report which shall, at a minimum, identify the hours labored by the employee on a
daily basis.
The Department’s project manager will compare the days labored in the progress report with the
“task tracking sheet” that in-house support employees will be asked to submit on a daily basis
(the task tracking sheet identifies the tasks in which the employee worked during the day, and
the time spent on each task). This task tracking sheet is to be submitted to the Department
project manager via e-mail. The Department recommends that the employee also send a copy of
such e-mail to his/her Consultant project manager.
Should there be a discrepancy between the task tracking sheets and the progress report, the
Department’s project manager will reject the progress report and request that it be revised and
resubmitted so that it is in full agreement with the task tracking sheets.
6. Evaluation of in-house support employees Employees providing in-house support services for periods longer than 21 working days will be
evaluated on a monthly basis by the Department’s project manager. The basis for evaluation
will be determined for each employee based on the nature of the task(s) assigned.
A copy of the evaluation will be provided to the employee and to the Consultant Project
Manager.
24
H. Fatal Crash Review The Department is responsible for reviewing each of the fatal crashes that occurs on the State
Highway System and determining the actions, if any, that the Department could take to:
1. Reduce the probability that similar crashes will occur in the future
2. Reduce the severity of similar types of crashes
As part of this task, the Consultant will be provided copies of fatal crash reports to:
1. Identify the location of the fatal crash
2. Determine the adequacy of the road’s:
a. Geometric configuration
b. Roadside elements
c. Fixed objects
d. Traffic control devices
i. Pavement markings
ii. signs
iii. signals
e. Lighting (if the crash occurred after sundown)
f. Drainage
3. Review the crash history (three years) of the location to identify any crash patterns
4. Perform field reviews, when deemed necessary, and document findings
5. Determine the probable cause(s) of the crash
6. Determine what actions, if any, the Department could take to:
a. Reduce the probability that similar crashes will occur in the future
b. Reduce the severity of similar type of crashes
7. Rank the recommended actions by their implementability (ex., availability of right of
way, etc) and their impact on mobility.
It is expected that the crash’s location will be identified and recorded in a GIS application, and
all findings will be stored on a relational database linked to the GIS application.
1. Task products Update GIS application and/or related relational database.
2. Performance time Fatal crashes for which a disposition (disposition = cause of crash + recommended actions) can
be made without the need for a field review shall be completed in no more than 45 minutes.
Fatal crashes for which a field review is needed to enter a disposition shall be completed in no
more than 3 hours or a time-frame specified by the department project manager.
While the Department may assign fatal crash reviews as a task to in-house support staff, it may
also assign it as a home-office assignment. Whenever fatal crash reviews are assigned as a home
office assignment the hours involved shall be negotiated without exceeding the time limits
specified above.
25
3. Format of submittals An updated file of the GIS application and/or relational database and a document that notes the
engineer that reviewed the fatal crashes constitute an acceptable form of submittal.
I. Skid Hazard Reporting System Update The Highway Safety Act of 1973 marked the first time that Congress specifically designated
construction funds for highway safety improvements. The act directed the states to identify
multiple safety hazards, slippery pavements among them.
The Department maintains a database of skid tests which have been performed along the State
Highway System. The Department is responsible for reviewing this database and ensuring that
slippery pavement problems are resolved in a timely manner. The Skid Hazard Reporting (SHR)
system includes mechanisms for tracking slippery pavement conditions from detection through
problem reduction.
Under this task, the Consultant shall update the SHR system by following the steps presented in
the most recent update of the document titled “SKID HAZARD REPORTING System – User
Documentation”. Currently, the document was last updated in October 2007.
J. “5% List” Analysis The Department is responsible for assessing the locations (spots and segments) that ranked
among the top 5% locations according to the number of crashes.
The Consultant will be tasked with reviewing the two 5% lists (spots and segments) provided by
the Department and:
1. Review crash history at each location
2. Identify crash patterns, if any
3. Identify actions the Department has taken, is currently taking, or plans to take at such
locations
4. If crash patterns are identified, Identify applicable safety engineering countermeasures
with the potential to:
a. Reduce the probability that crashes of a specific crash pattern occur again, or
b. Reduce the severity of crashes occurring in a specific crash pattern
5. Identify if the recommended safety engineering countermeasures are implementable
6. Recommend whether an additional safety study is needed. The additional safety study
would identify the crash reduction factors of the countermeasures identified in the
previous steps, the costs of the countermeasures as well as its operational consequences.
K. Geographic Information Systems (GIS) Application
Development The Department relies on GIS as a tool to systematically identify locations with crash patterns
that can be reduced or eliminated through the implementation of safety engineering
countermeasures.
26
The Department has used its internal resources to develop a GIS tool that allows the
Department to identify signalized intersections with specific crash patterns. For instance, the
tool enables the Department to identify the signalized intersections that had the highest number
of a certain subset of crashes. These subsets can be created based on a crash’s:
1. Crash type (ex., rear end, angle, etc)
2. Harmful event (ex., failed to yield right of way, etc)
3. Type of injury (ex., none, severe, fatal, etc)
4. Hour of day (ex., 1:00am, 3:00pm, etc)
5. Day of week (ex., Monday, Wednesday, etc)
6. Month of year (ex., February, June, etc)
7. Distance from the intersection (etc, 100ft, 250ft, etc)
8. Pavement condition (ex., wet, dry, etc)
Under this task the Consultant will be expected to develop a GIS application that expands the
capability of the Department’s existing application. A sample of the GIS applications that the
Consultant should be prepared to develop include:
1. Tool to rank non-signalized intersections based on the occurrence of a specific crash
pattern (ex., angle crashes, left turn crashes, etc)
2. Tool to rank roadway segments based on the occurrence of a specific crash pattern (ex.,
run off the road, head on, etc.)
3. Tool to identify spots and/or roadway segments that meet certain conditions (these
conditions could be related to the location crash history and/or geometric
configuration), for instance;
a. Identify non-signalized intersections with more than XX angle crashes in a YY
year period (where XX and YY are variables)
b. Identify signalized intersections with protected/permissive left turn phasing and
with more than XX left turn crashes in a YY year period
c. Identify one (1) mile segments where the percentage of night time crashes is
greater than YY % in the most recent year
d. Identify one (1) mile segments of undivided roads with more than XX head on
and angle crashes in a 3 year period
The cost, deliverables and schedule for this task are to be negotiated prior to assignment of the
Task Work Order.
L. Net Present Value Driven Studies Under this task the Consultant will be responsible for developing a safety study, from beginning
(i.e., identification of study location) to end (i.e., approval by the SRC) that meets or exceeds a
pre-established NPV target. The Consultant will be provided with guidance and criteria that
needs to be followed and met. In this type of assignment, payment will be made based on
percentage completed. The metric used to measure progress will be the NPV of the project(s)
approved by the SRC, expressed as a percentage of the target NPV. If the NPV of the project(s)
approved by the SRC exceeds the target NPV, payment will be capped at the pre-negotiated
amount.
27
The Department project manager will, prior to the SRC meeting, review the project’s NPV to
ensure that the NPV methodology was properly applied; the correct crash reduction factors were
used; the proper numbers and values per crash were used, etc. The Department project
manager will have final say on the validity of an NPV calculation. No project shall be presented
to the Safety Review Committee if the Department project manger does not support the
Consultant’s NPV calculation.
Before issuing this type of assignment, the Department will provide specific guidance and
criteria for the Consultant to follow and meet. Typical guidance provided under this type of
assignment includes:
1. Procedure to calculate NPV
2. Cost per crash information
3. Other information, as necessary
Typical criteria provided under this type of assignment includes:
1. The emphasis area (from the Florida Strategic Highway Safety Plan), or type(s) of crash
(es) that the project must intend to reduce. For instance, the Consultant may be limited
to developing a project that generates all NPV from reducing crashes that involve
vulnerable users (i.e., pedestrians and bicyclists)
2. The geographical region where the project is to take place. For instance, the Consultant
may be allowed to develop a project anywhere in the District, or it may be restricted to a
certain County, City, etc.
3. The number of projects that may be developed to accumulate the target NPV. For
instance, the Consultant may be directed to produce all the required NPV in one project
alone, or it may be allowed to develop as many projects as necessary to reach the NPV
target
4. The time that the Consultant will be provided to develop projects from beginning to end
5. Other criteria, as directed by the Department’s project manager
Under this type of assignment, the Consultant must be aware that a project that is not approved
by the SRC does not generate any NPV. Only SRC approved projects generate NPV that allow
the Consultant to make progress towards meeting the target NPV.
M. Data Collection Under this task the Consultant may be required to conduct, on a cost-unit basis, any of the
following types of counts:
1. Automated Data Recorder (ADR) Counts
a. 24-hour (1 day) traffic count (15 minute intervals)
b. 48-hour (2 days) traffic counts (15 minute intervals)
c. 168-hour (7 days) traffic counts (15 minute intervals)
d. 336-hour (14 days) traffic counts (15 minute intervals)
2. Turning movement counts
a. 4-hour turning movement and/or pedestrian counts
b. 6-hour turning movement and/or pedestrian counts
28
c. 8-hour turning movement and/or pedestrian counts
3. Pedestrian volume counts
4. Vehicle classification surveys
a. 24-hour vehicle classification counts (15 minute intervals)
b. 48-hour vehicle classification counts (15 minute intervals)
Counts conducted by the Consultant shall be taken during the weekday period of Monday
afternoon through Friday morning, with the exception of 7 and 14 day counts, unless approved
in writting by the Department’s project manager.
1. Quality control for data collection The Consultant shall perform independent quality control of all data collected for the
Department. At a minimum, the following quality controls shall be performed:
a) For ADT counts
The Consultant must ensure that:
24-hour directional split < 15%, and
Peak hour directional split < 15%
If any of the directional splits exceeds the tolerance threshold, the Consultant must justify, in
writing, potential reasons why the threshold was exceeded. If the Department does not deem
such justification valid, the Consultant shall repeat the counts at its own cost. If however, the
second count is consistent with the first (i.e., the threshold is exceeded, again), the Department
will reimburse the Consultant for the second count.
b) For vehicle classification counts
The Consultant must ensure that:
Vehicles assigned to unknown category < 10%
If the percentage of vehicles assigned to the unknown category exceeds 10%, the Consultant
must justify, in writing, potential reasons why the threshold was exceeded. If the Department
does not deem such justification valid, the Consultant shall repeat the counts at its own cost.
c) For turning movement counts
The Consultant must ensure that when volume A and volume B are compared, they do not differ
by more than +/- 15% (i.e., the tolerance).
Volume A Volume B Tolerance

2. Task products The Consultant shall provide the following documentation at the time of submittal:
A CD-ROM, or any other digital media approved by the Department’s project manager,
containing the collected data in the following formats:
o PDF format, and
o Spreadsheet format compatible with Microsoft Excel 2007
Hard copy of collected data using survey processing software (SPS) 24 hour synopsis
report.
Electronic files provided to the department shall be named according to the following rule:
Rule: Year-month-day-SectionNumber-milepost.extension

Count taken on January 25, 2009 in the intersection of SR 818 (Griffin Road) and Nob Hill Road / SW 100 Avenue
When such a rule does not allow the Consultant to provide a description of the location where
the counts were taken (ex., counts taken on a state road without a section number, etc), the
Consultant shall request a new naming convention/rule from the Department’s project
manager.
