Introduction ' ,�.

NTMP
Neighborhood Traffic Management Program
The Neighborhood Traffic Management Program (NTMP) was created to ensure the
safety of our Collier County neighborhoods from speeding drivers and to restore local
streets to the residents.
Typical speeding complaints from homeowners living on residential streets in Collier
County illustrate that a majority of motorists drive over the 30 mph speed limit. Those
who exceed the speed limit come from all age groups. Why do they speed? The studies
show that:
• Local residents drive faster on their local streets because they
feel familiar and comfortable.
• Outsiders use local streets as short cuts to busy arterial roads.
Traffic conditions on residential streets can greatly affect neighborhood livability. When
our streets are safe and pleasant, the quality of life is enhanced. When traffic problems
become a daily occurrence, our sense of community and personal well-being are
threatened. By addressing high vehicular speeds and cut-through volumes, traffic
calming can increase both the real and perceived safety of pedestrians and bicyclists,
and improve the quality of life within the neighborhood.
This revised NTMP was developed, specifically, by Collier County and the Traffic Calm-
ing Task Force. It's mission is to identify, qualify and address dangerous driving behav-
iors. Traffic calming may be defined as: The combination of mainly physical measures
that reduce the negative effects of motor vehicle use, alter driver behavior, and improve
conditions for non-motorized street users.
Note: This program was not designed as a regulatory arm for neighborhood
control of internal traffic, which would then become an enforcement issue.

Goals Objectives & Policies
Goals:
It is the goal of the Collier County Neighborhood Traffic Management Program (NTMP)
to establish procedures and techniques that will promote neighborhood livability.
Although livability has no precise definition, it can be thought of as encompassing the
following characteristics:
• The opportunity to walk or bike within the roadway area with a feeling of safety.
• The opportunity to interact socially with neighbors without traffic related
distractions or threats.
• A sense of community and neighborhood identity.
• A balanced relationship between the multiple uses and needs of a
neighborhood.
Objectives:
• To promote safe and pleasant conditions for residents, pedestrians,
bicyclists, and motorists on neighborhood streets.
• To reduce vehicular speeding on local neighborhood streets.
• To preserve and enhance pedestrian and bicycle access to neighborhood
destinations.
• To enhance a sense of community and neighborhood identity.
• To encourage citizen involvement in neighborhood traffic management
activities.
• To provide a process that will address neighborhood traffic management
requests.

Policies:
• Through traffic should be routed to the major roadways designated in the Trans-
portation Element of the Collier County Growth Management Plan.
• Re-routed traffic that results from a traffic management project should be
evaluated on a project-by-project basis.
• Emergency vehicle access should be preserved.
• Roadways as shown in Exhibit"A" are not eligible for the NTMP.
• Collier County shall employ a variety of traffic calming devices to achieve the
NTMP's objectives. Such traffic calming devices shall be planned and designed
in conformance with sound engineering and planning practices.
• To implement the NTMP, certain procedures shall be followed in processing
neighborhood traffic management requests in accordance with applicable
codes and related policies and within the limits of available resources. At a
minimum, the procedures shall provide for:
• Submittal of project proposals.
Evaluation of proposals by staff.
• Citizen participation in plan development and evaluation.
• Methods of temporarily testing traffic management plans when needed.
• Communication of any test results and specific findings to area
residents and affected neighborhood organizations before installation of
permanent traffic calming devices.
• Review and prioritization of traffic calming projects requiring funding.
• Follow-up study and findings report.

How the NTMP works
The process in a nutshell:
• The NTMP Project Manager receives and reviews requests for traffic calming.
• The requests are then subjected to a qualifying process that includes field counts
and observations, and input from citizens in the affected area(s).
• Working as a team and with the "three E's" process" (education, enforcement, and
engineering), citizens and staff derive solutions that may be implemented to
address specific problems.
• Next it is determined who will fund the project.
• Funding for the county road NTMP projects must be sensitive to the
prioritization criteria. Qualified projects, approved for private road systems,
are normally funded by HOA's or Municipal Service Benefit/Taxing Units
(MSB/TU's). Homeowners requesting calming devices along dead-end
streets are required to fund those installations.
• Once qualified, traffic calming projects are integrated into the existing schedule of
county traffic calming projects.
• Following the installation of the project, county staff will begin it's evaluation in order
to review it's effectiveness and impact.

What do I do?
Community approval is one of the most
important steps in any traffic calming program.
1. LODGE A COMPLAINT:
A complaint needs to be made directly to County staff. It can be made by any
person or group living in the affected area such as: a citizen(s), a Home
Owners Association (HOA), or by a city or County staff member such as the
Collier County Community Traffic Safety Team.
Please note: Only county owned, residential streets are eligible for any county
assistance other than for general consulting services. A listing of in-eligible
(non-residential) roads are shown in Exhibit"A".
To lodge a complaint, please contact the Transportation Planning Department:
By PHONE: NTMP Project Manager 239-252-5782
By MAIL: NTMP Project Manager, Collier County Transportation Division
2800 Horseshoe Drive North, Naples, FL 34104
BY EMAIL: Transplanning @colliergov.net
2. COMPLETE AN APPLICATION:
A completed application must be submitted to the County.
Please use the official NTMP Application form shown as Exhibit"B". The
completed application identifies the contact person, address, phone number,
date and nature of the complaint.
3. CIRCULATE PETITION#1:
The resident, citizen, or group must obtain a show of community support and
backing by circulating a petition and acquiring signatures of at least 10% of the
households along the affected roadway.
Please use the official NTMP Petition form shown as Exhibit"C".

4. TRAFFIC STUDY PERFORMED:
The County staff then reviews the problem at the site and orders a traffic study
in order to determine if minimum eligibility criteria are met.
The chart above shows the criteria.
5. CIRCULATE PETITION #2:
If minimum criteria are met, a second and broader petition must be circulated
by the citizen, resident, or group within the identified petition area. This time,
signatures must be obtained from more than 51% of households and/or
businesses in the petition area.
6. NEIGHBORHOOD WORKSHOP:
Once the second petition is submitted, county staff will call a neighborhood
meeting to review data findings. A neighborhood "traffic team" is established to
be a point of contact with the county and the group will be educated about the
practice of"Traffic Calming". The County staff and Traffic Team begin
developing a project concept involving the"three E's":
Education Programs that remind speeders of the negative effects
of their action
Enforcement Police presence to enforce speed limits.
Engineering The construction of a physical change to the roadway
to deter speeding. Examples include: Deflections,
Obstructions and/or Roadmarkings. It can
also include the use of signs and pavement
markings to obtain the desired effect.

What do I do?
7. START EDUCATION PROCESS: (more detail on pg. 13)
Traffic Calming Education produces activities that inform and seek to modify
driver behavior. Techniques include printed information, meetings and work
shops with staff, interaction with neighbors, signing campaigns, neighborhood
speed watches, school programs, and parent outreach.
8. START ENFORCEMENT PROCESS: (more detail on pg. 14)
After a pre-defined period of time, the results of the educational process will be
evaluated. If additional measures are required, then the enforcement process
will begin. Enforcement involves a more intensive police presence and a
greater allocation of time to enforcing the speed limit in a particular neighbor-
hood. Unfortunately, it is often not practical to maintain a police presence at the
level needed to permanently lower speeds. However, consistent visible
enforcement does lead to respect of the speed limit by motorists.
9. COMMUNITY MEETING &ENGINEERING OPTIONS: (more detail on pg. 15)
The County staff and Traffic Team now meet again to determine if next steps
are necessary. If they are, ENGINEERING concepts and options will be
discussed.
The Traffic Calming Task Force examined many different traffic calming engineered
techniques. Realizing that Collier County's/Naples' neighborhoods are not all the
same and there are a variety of street designs within neighborhoods,the Task Force
include a wide range of techniques in this program that can be considered to
address the differing traffic conditions.
An appropriate engineering technique for the community and it's traffic problem
will be decided on at this meeting.
9
16A10
10. DETERMINATION OF FUNDING:
Also decided at the above meeting will be who will finance the project. Only county
owned local roads are eligible for any application for funding from the county. To be
considered for an NTMP grant, the project must be ranked according to the
"Project Prioritization" criteria. Exhibit"D" Rankings indicate which projects, or
portions thereof, are to receive funding as well as the prioritization of the project
within the county schedule. Privately owned residential neighborhoods such as
gated communities must privately fund and manage their own projects. These
neighborhoods, while not part of the funding prioritization process, are still subject
to applicable planning and engineering review and permitting as identified in this
document.
11. BOARD APPROVAL:
If County funding is available, the community's request for an engineered traffic
calming project is included on the agenda at the next available Board of Commis-
sioners' meeting. At this public meeting, the Board will vote to approve/disapprove
the request.
12. PROJECT IS DESIGNED AND INITIATED
If the go ahead is given by the Board, then County staff schedules the design and
implementation of the project according to the scores of the prioritization rankings.
13. MONITORING AND IMPACT STUDIES
Immediately following the installation of the project, County staff will begin an
evaluation of it including field observations, traffic counts, speed studies, and other
data collection as staff feels may be appropriate to review the effectiveness and
impacts of the traffic calming project.

Traffic Calming Techniques
The implementation of traffic calming measures has the potential to create
controversy, so it is recommended that it occurs as the final step of a
three-step process referred to as the "three E's" (education, enforcement,
and engineering). Let's examine each of these in detail.
Step # 1 : EDUCATION
Educational programs seek to remind speeding drivers of the negative effects of their actions, often by
stressing that the community's children and elderly are the most at risk. Educational campaigns may
use brochures or neighborhood newsletters to spread this message. Newsletters may also contain
information on speeding fines (particularly in school zones), pedestrian and bicycle safety tips, and
information on average speeds in the neighborhood.
Techniques also include printed information, meetings and workshops with staff, interaction
with neighbors, signing campaigns, neighborhood speed watches, school programs, and parent
outreach.
Signs:
One method of educating the driving public is to install a sign informing them that traffic
calming devices have been installed.
Advantages:
• Informs and alerts driver of oncoming devices;
• Improves safety of the technique or device being used; and
• Improves effectiveness of the technique or device.
Disadvantages:
awn
PONTEFRACT ROAD
• More signage on the street, sometimes considered un-
sightly.

TECHNIQUES: Enforcement
Step # 2: ENFORCEMENT
Enforcement involves a more intensive police presence and a greater allocation of time to
enforcing the speed limit in a particular neighborhood. There are a variety of methods used
by the police.
Mobile radar display: advises motorists of the speed at which they are
traveling
Advantages:
• Educational tool; 4..
• Very good public relations tool; and 1 .k r
xis
• Useful especially in school and construction zones
where spot speed reduction is important.
Disadvantages: t
• Requires periodic enforcement;
yayti;i ,
• Effective for limited duration; and
• Unit moves frequently, which requires personnel.
Periodic monitoring by police: for speeding and other violations .
Advantages:
• Good temporary public relations tool; and
• Serves to inform public that speeding is
undesirable behavior, for which there are consequences.
Disadvantages:
• Effect is not permanent; and
• Enforcement is an expensive tool.
14
16A10
TECHNIQUES: Engineering
Step # 3 • ENGINEERING
If Education and Enforcement Procedures have not controlled the traffic problem, then
the county, along with the community traffic team, will begin to explore options for an
engineered change to the road.
Neighborhoods are not all the same and there are a variety of street designs within
neighborhoods. With this in mind, the Task Force has included a wide range of
techniques in this program that can be used to address differing traffic conditions.
The selection of traffic calming measures should be based on the following:
• The measure of potential to address volume or
speed reduction on affected roadways.
• The type of roadway.
• Actual site conditions.
Techniques:
When choosing a technique to use, both the physical and psychological nature of the
problem is examined. The physical problem itself is usually addressed by changing the
width of the street since wider roads encourage higher automobile speeds. Techniques
such as neck downs, roundabouts and medians all decrease road width.
The psychological aspect involves understanding how the motorist thinks. If a motorist
can see into the distance, the tendency is to increase speed. The interruption of sight
lines, with changes in the road's direction will cause motorists to slow down. Using
techniques such as chicanes and roundabouts, or breaking the road into smaller
visual units by changing the surface pavement, such as brick pavers or stamped
concrete, causes the driver to slow down. It also means motorists widen their vision
field, becoming much more aware of pedestrians and bicyclists. Changes in the road
..............................
a. k rgaw
15
16A10
design force traffic to travel at a slower, more even pace. Traffic calming may also be
achieved by changing the psychological feel of the street. Streets using different
surface types, vertical landscaping or narrowed lanes create the appropriate space
for a relaxed, pedestrian-friendly feel. These psychological changes give motorists cues
that they are no longer on a major roadway but are in a different environment that is
shared with people.
All traffic calming techniques have a limited range of effectiveness. To achieve traffic
calming objectives, some techniques need to be placed every 250-400 feet. If traffic
calming techniques are used too sparsely, traffic may slow close to the installation, but
the overall speed will probably not decrease. One technique may be used multiple
times or multiple techniques may be used in conjunction with one another. Most
techniques will affect noise, air quality, congestion, fuel consumption and many other
factors. Some techniques can improve these conditions, others may cause these prob-
lems to increase.
Emergency vehicle access and response time must be considered when designing and
installing traffic calming devices. Emergency vehicles, particularly ambulances, have
more difficulty with "vertical" devices such as speed humps than with "horizontal"
devices such as centerline and edgeline striping. Likewise, bicyclists and pedestri-
ans must be kept in mind when developing a traffic calming strategy, as some de-
vices can obstruct their movements. Many devices can be modified to allow bicy-
clists and pedestrians to by-pass them. For instance, a diverter can be fitted with a
bicycle/pedestrian link to allow for through movement.

Do's and Dont's of the Planning Process
Do the following:
• Install temporary traffic calming features and monitor them for a period of time before
installing the permanent features. Testing features on site prior to permanent installation
will relieve resident anxiety about the impact on their own driving patters and driving
behaviors will adjust to the new route circumstances.
• Have an organized program including public involvement with plans and policies ap-
proved and supported by the local government. Emphasize the selected treatments(s)
will be initially in a "test" mode, with permanency pending the outcome measurement.
Be able to describe what is being done to keep traffic off residential streets.
• Channel public resources by prioritizing traffic calming request according to document-
able criteria, setting thresholds of volume, speed, etc., to merit treatment.
• Involve the local service agencies, including fire, police, and emergency medical ser-
vices personnel, from the start.
• Consult with fire department and EMS personnel to develop the preferred design, par-
ticularly with speed humps and traffic circles.
• Review traffic patterns in the neighborhood as a whole. Avoid solving the problem on
one neighborhood street by just shifting the traffic to another neighborhood street.
• Make certain that all signing, pavement markings, and channelization is in accordance
with the Manual on Uniform Traffic Control Devices (MUTCD), the AASHTO Policy on
Geometric Design of Highways and Streets, and the Florida Roundabout Guide.
• Check sight distances for vehicles, pedestrians, and bicyclists. Sight distance should
be consistent with the dimensions shown in CHAPTER 3 — GEOMETRIC DESIGN or
CHAPTER 16— RESIDENTIAL STREET DESIGN of the FDOT Manual of Uniform Mini-
mum Standards.
• Become familiar with the traffic calming features used in other communities and as-
semble references so that residents can be directed where to see them.
• Check sight distances by visiting the site before and after installation. Do parked cars
obstruct sight distances? Do landscaping or other features obstruct sight distance?
• Review the illumination at night. Are additional street lights needed? Does landscaping
block the light? Is there a shadow on one side of a median or traffic circle that might
hide pedestrians from view?
• Review the channelization during the day and at night. Is it a clear approach from all
directions? Can it be seen at night? Watch the traffic: Is the driving public confused by
the signing and channelization? Make adjustments as needed.
17
16A10
• Review the site for utility conflicts. Is there a fire hydrant? Does it need to be
moved?Are there existing utilities in the way?
• Check the storm water drainage. Will the storm drain system need to be moved
or revised? Can the runoff flow through or around the device?
Don't do the following:
• Install neighborhood traffic calming features without a well-engineered program
supported by the public.
• Install neighborhood traffic calming features on arterial or collector streets as
shown on Exhibit"A".
• Install neighborhood traffic calming features on streets without curbs unless sup-
plemental features or other design considerations are included to keep vehicles
within the traveled way.
• Place neighborhood traffic calming features in front of driveways.
• Neglect to check for conflicting utilities or drainage considerations.
INAPPROPRIATE TRAFFIC CALMING TREATMENTS
Stop Signs
When used for traffic calming, stop signs often do one or more of the following:
• Increase midblock speeds along the street because of drivers trying to make up
for lost time.
• Increase noise because of quick accelerations and decelerations.
• Increase pollution.
• Reduce drivers' expectation of a uniform flow.
• Relocate the problem.
• Cause disrespect for stop signs by drivers and bicyclists.
For these reasons, stop signs should not be used for traffic calming.
18
16A10 4
Signage
• Novelty signs -While signs such as CHILDREN AT PLAY, SENIORS CROSS HERE, SLOW
DEAF CHILD, and DEAR CROSSING (meaning loved one) may make an infrequent roadway
user aware of a specific local population, most regular users of the roadway are unaffected by
the signs.
• Odd speed limit - NEIGHBORHOOD SPEED LIMIT 23 MPH and other odd speed limit signs
place a high dependence on police to monitor speeders and are not consistent with the national
practice required by the MUTCD of posting speeds limits in 5 mph increments.
• Crosswalks — Standard crosswalks marked only with signs and pavement markings do not af-
fect motorists' speeds and should not be used by themselves as traffic calming treatments.
• Bike lanes — Standard bike lanes are not traffic calming treatments. They can be used to pro-
vide additional space between the sidewalk and motor vehicle traffic, but should not be used by
themselves for traffic calming.
• Speed trailers —While speed trailers can be used as part of a traffic calming program for edu-
cational awareness, they have no lasting effect on motorists' behavior.
• Reduced speed limit signs — Reduced speed limits without physical traffic calming measures
do not slow drivers and should not be used for traffic calming.
• Rumble strips — These applications have high maintenance requirements and can cause se-
vere noise problems. Also, they can be an obstacle to bicyclists.

SPEED CONTROL: Vertical Deflection
Raised Crosswalks a.k.a. Raised crossings, sidewalk extensions
Raised crosswalks are Speed Tables outfitted with crosswalk markings and signage to channel
pedestrian crossings, providing pedestrians with a level street crossing. Also, by raising the
level of the crossing, pedestrians are more visible to approaching motorists.

Advantages:
• Raised Crosswalks improve safety for both pedestrians and vehicles;
• If designed well, they can have positive aesthetic value;
• They are effective in reducing speeds; and
• They are good for locations where pedestrian crossings occur at haphazard locations and
vehicle speeds are excessive.
Disadvantages:
• Textured materials, if used, can be expensive;
• Impacts on drainage needs to be considered; and
• Noise and air pollution may increase.

SPEED CONTROL: Vertical Deflection
Speed Humps a.k.a. Road humps, undulations.
Speed humps are rounded raised areas placed across the roadway. They are generally 10 to
14 feet long (in the direction of travel), making them distinct from the shorter "speed bumps"
found in many parking lots, and are 3 to 4 inches high. The profile of a speed hump can
be circular, parabolic, or sinusoidal. They are often tapered as they reach the curb on each
end to allow unimpeded drainage.

Advantages:
• Speed Humps are relatively inexpensive;
• They are relatively easy for bicycles to cross if designed appropriately;
• They are very effective in slowing travel speeds; and
• They are good for locations where very low speeds are desired and reasonable, and noise
and fumes are not a major concern.
Disadvantages:
• They cause a "rough ride" for all drivers, and can cause severe pain for people with certain
skeletal disabilities.
• They force large vehicles, such as emergency vehicles and those with rigid suspensions, to
travel at slower speeds;
• They may increase noise and air pollution; and
• They have questionable aesthetics.

Speed Tables a.k.a. Trapezoidal humps, speed platforms.
Speed tables are flat-topped speed humps, also 3 to 4 inches high but with a sloped approach
taper on each side of a flat top. They are generally 20 to 24 feet wide. Comfortable speed
limited to 20 to 25 mph.

Speed Cushions
Speed cushions are several small speed humps installed across the width of the road with
spaces between them. They are generally installed in a series across a roadway resembling a
split speed hump. The design of speed cushions forces cars to slow down as they ride with one
or both wheels on the hump.

Advantages:
• The wider axle of fire engines allows them to straddle the cushions without slowing down;
• They are relatively easy for bicycles to cross if designed appropriately;
• They are less costly than speed tables but are considered just as effective; and
• They are good for locations where very low speeds are desired and reasonable, and noise
and fumes are not a major concern.
Disadvantages:
• They cause a "rough ride" for all drivers, and can cause severe pain for people with certain

Textured Pavement a.k.a. Change in pavement texture (such as asphalt to
brick).
Textured pavements are roadway surfaces paved with brick, concrete pavers, stamped asphalt,
or other surface materials that produce constant small changes in vertical alignment. Though
including textured pavements among vertical features may appear a stretch to some readers,
one need only observe travel speeds on old cobblestone and brick streets to appreciate the
rationale.

Advantages:
• If designed well, they can have positive aesthetic value;
• They can calm two streets at once; and
• They are good for intersections with substantial pedestrian activity.
Disadvantages:
• They tend to be expensive, varying by materials used;
• Impact to drainage needs to be considered; and
• Require increased maintenance

Speed Kidney
Speed kidneys are a new traffic calming device that consist of a raised and curved area placed
at the center of any lane. Drivers can choose to adopt a curved path, which moderates speed
without vehicle damage or vertical discomfort.

Advantages:
• Speed kidneys are relatively inexpensive;
• No delay for emergency vehicle response time, by straddling the main speed kidney;
• No vehicle damage or vertical discomfort;
• They are very effective in moderating travel speeds; and
• They produce less negative environmental impacts than speed humps
Disadvantages:
• They cause a "rough ride"for drivers if they choose to drive straight over the kidneys; and
• They have questionable aesthetics.

Centerline and Edgeline Striping
a.k.a. Visually narrowing the roadway(Psycho-Perception Control).
Painting an edgeline several feet from the pavement edge has the effect of visually narrowing
the roadway. A double yellow line striped down the center of roadway might have a
comparable effect, visually limiting drivers to half of the road. In theory, the perceived narrow-
ing could cause a modest speed reduction,just as a real narrowing causes a modest speed
reduction.

"Traffic Calming" Credits
These notes support Statements on Page 5 of this Booklet regarding the
practice of"traffic calming".
The authority to implement "Traffic Calming" comes from the following
sources:
1. Collier County Growth Management Plan, Transportation
Element(VI). Goals and Objective & Policies.
(VI) Objective 9: The County shall encourage neighborhood
involvement in the establishment and maintenance of safe and
pleasant conditions for the residents, pedestrians, bicyclists and
motorists on neighborhood streets, which are not classified as
arterials or collectors, through the implementation of the Collier
County Neighborhood Traffic Management Program (NTMP). In
developing strategies and measures to encourage such condi-
tions, the NTMP shall consider the impact of such strategies and
measures on the adjacent arterial and collector systems (from a
level-of-service and operational standpoint).
2. Board of County Commissioners Resolution 95-608, which
establishes the Neighborhood Traffic Management Program.
3. The Unified Land Development Code (ULDC), Chapter 4,
Subdivision Design Requirements. § 4.03.05 (A) Blocks. The
length, width and shape of blocks shall be determined with due
regard to:
(4.) Where special topographical conditions exist, block
lengths greater than 660 feet shall be approved by the County
Manager or designee pursuant to procedures set forth in Chap-
ter 10. Traffic calming devices, as approved in the Neighborhood
Traffic Management Program, shall be provided in block lengths
greater than 660 feet.
Chapter 6. Infrastructure Improvements and Adequate Public Facilities
Requirements. § 6.06.00 Transportation System Standards. § 6.06.01
Street System Requirements.
(G.) Use of local streets by cut-through traffic shall be discour-
aged, using methods (like traffic calming) that do not compromise
connectivity or reduce the number of access points to the subdi-
vision.
