Re: Resolution 57-23 –Approving the City Of Dublin’s Speed Management Program
And Repealing The City’s Current Traffic Calming Policy
Background
At the June 12, 2023 City Council meeting, the proposed Speed Management Program (Program)
was discussed and Council provided guidance on several topics. This memo and associated
resolution present the proposed Program for Council’s review and adoption.
City Council referred this topic to Community Services Advisory Commission at the June 28, 2021
Council meeting. The City worked with Toole Design to develop a new Speed Management
Program to build on national best practices, state of the art technology and local community
engagement. CSAC discussed the Program at three meetings: November 9, 2021, September 12,
2022 and December 13, 2022. CSAC recommended to advance the Program for City Council’s
review at the third meeting. A public meeting was also held on August 9, 2022. City Council
discussed the topic at three meetings, a Council Work Session on March 6, 2023 and two City
Council meetings on April 24, 2023 and June 12, 2023. The proposed Program is the culmination
of this Program development, discussion and community engagement over the past two years.
Summary
Based on the recent Council meeting discussion, the following direction has been incorporated into
the proposed Program. The revised Program, Toolbox and Implementation Guide are attached for
reference.
Discussion Question: 1. Is Council supportive of the proposed revised Vision Statement
for the Speed Management Program?
Council directed to keep the “all” in the Vision Statement and accept the other proposed changes,
to read:
“The Speed Management Program will provide a framework for a data-driven approach to speed
management. The Program goals strive to create safe and comfortable streets for all residents
and road users across Dublin including people walking and rolling.”

Discussion Question: 2. Is Council supportive of the proposed revisions to the speed
management categories?
Council supported the proposed revisions to the speed management categories, as reflected in the
table below. The categories acknowledge the differences in speed management strategies based
on the functional classification and speed limit of each roadway, as shown below. Staff has
incorporated an example project in the Program to help explain how it will be administered, which
is included in the revised Program as attached.

Discussion Question: 3. Is Council supportive of the proposed revision to Category 3
for vertical devices in the Speed Management Toolbox?
Council confirmed the proposed changes for the applicability of vertical measures within Category
3 solutions in the Speed Management Toolbox, to read:
• Vertical Measures, such as speed cushions, should only be considered if other
measures have been unsuccessful. If after at least one Category 3 Speed Management
Solution has been tried and proven to be ineffective, and speeds are still in Category 3,
then vertical measures will be evaluated as described in Step 3 of the Speed
Management Program.
Discussion Question: 4. Would Council like to include the Education and Awareness
Category as an additional Speed Management Category?
Council determined that since the education and awareness techniques were already being
implemented there is no need to specify this as a stand-alone category. Supporting language is
included in the Program supporting education and awareness:
Step 1. Collect data and educate
• Residents have access to the Education and Awareness Solutions within the Speed
Management Toolbox beginning in this step of the Speed Management Program.
Within the Speed Management Toolbox, the following solutions are available:
Public Awareness Campaigns can be messaged through a variety of communication tools such
as social media, email, fliers, newsletters, and signs to help others understand how small changes
can make a big difference.

Police Loaner Laser Program allows residents to be trained to use a handheld laser gun to
measure speeds of traffic on a roadway.
Police Ride Along Program invites a resident to ride along with an officer based on interest.
Yard signs are a trend in grassroots speed management efforts. Neighbors can take action by
placing a sign in their yard to encourage slower speeds, through coordination with their HOA or Civic
Association. The effectiveness of yard signs will be evaluated as the program progresses to
determine if this is a viable part of the Program.
Discussion Question: 5. Would Council like to include temporary vertical devices in the
Category 2 Speed Management solutions?
Based on the data showing vertical devices to be more effective when speeds are higher, such as
in Category 3, Council directed staff to keep vertical measures as solutions only applied in
Category 3.
Discussion Question: 6. Should staff pursue a vertical traffic calming device project,
such as temporary speed cushions, on Cacchio Lane?
Council would like to pursue a vertical traffic calming project. Staff will first engage the area HOAs,
Civic Associations and residents. Transportation and Mobility will work with Communications and
Public Information to develop information to share with the neighborhood and temporary public
engagement signs to gain feedback from residents. If the neighborhood is supportive, staff will
advance the initiative described in the City Council memo dated June 6, 2023, follow the process
detailed under Speed Management Category 3 in the Program and could install temporary speed
cushions as early as Q3 2023 depending on the outcome of the engagement.
Discussion Question: 7. How many tactical urbanism pilot projects should staff pursue
and should the topic remain with Council or return to CSAC?
Based on Council’s acknowledgment of the benefits of CSAC’s review, along with the desire to keep
the projects advancing quickly, staff proposes up to three tactical urbanism pilot projects be
discussed at an upcoming CSAC meeting with recommendations advanced to City Council in a
timely manner.
Tactical urbanism projects range in scope and scale that are characterized by being flexible, short-
term projects. Tactical urbanism could be incorporated into Dublin’s landscape in several ways,
including painted curb extensions, planters, street trees, mini traffic circles with paint and/or
delineators, textured and colored asphalt, or chicanes and colorful crosswalks.
Resolution 57-23 – Approving the City Of Dublin’s Speed Management Program And Repealing The City’s
Current Traffic Calming Policy
July 25, 2023
Page 4 of 7
Tactical urbanism projects will be highly dependent on resident feedback in order to be an
effective tool and to build a successful program. Therefore, staff will also seek feedback regarding
proposed tactical urbanism projects from residents near project locations.
Discussion Question: 8. Should staff request additional funds with an upcoming
supplemental appropriations ordinance for more than one set of speed safety cameras
in 2023?
Staff plans to purchase an initial set of speed safety cameras through existing budgets in 2023.
Staff plans to include funding for a second set of speed safety cameras in the upcoming Q3
Supplemental Appropriations Ordinance, based on the direction from Council. If approved, staff will
purchase this set of speed safety cameras for installation in 2023. A third set will be proposed
through the 2024-2028 CIP process under the Police Department.
Discussion Question: 9. Are there additional considerations Council would like to be
included in the Speed Management Program?
Several topics were discussed by City Council for consideration:
1. Noise related to vehicles was discussed. Staff understands the concern with noise, but since
noise is not always associated with speed (noisy mufflers, large vehicles accelerating, etc.), it is
not best placed in this Program. Police have updated the Traffic Enforcement Action Policy to
address vehicle noise enforcement, as well as their commitment to engaging in regular
enforcement campaigns.
2. Adding trees and targeted signs were discussed as additional design solutions for speed
management. Street trees and yard signs are now included as solutions in the Speed
Management Toolbox. The City’s long standing practice of planting street trees along travel
ways supports speed compliance and enhances the pedestrian experience. If street trees are
identified for a specific location, Transportation and Mobility staff will coordinate with Parks and
Figure 1. Examples of Tactical Urbanism
Resolution 57-23 – Approving the City Of Dublin’s Speed Management Program And Repealing The City’s
Current Traffic Calming Policy
July 25, 2023
Page 5 of 7
Recreation and Public Services staff to incorporate such trees. Street trees are added to the
tactical urbanism solutions within Category 2:
Tactical Urbanism Solutions:
1. Street Width Reduction Using Pavement Markings visually narrows the roadway, and
helps to reduce speeds. This can be done in a variety of ways, including marking on-street
parking spaces (as shown in the example below) or by adding a wide edge line to any street
type, including curb and gutter.
2. Stamped and Colored Asphalt can be used for emphasizing crosswalks or pavement other
areas.
3. Other tactical urbanism solutions, such as street trees, are also included in Category 2.
3. Council noted rotating driver feedback signs improve driver compliance, along with resident
support, and directed the purchase of additional signs for the program. Based on approval in
the 2024 operating budget, staff will purchase and deploy an additional set of rotating driver
feedback signs, for a total of three sets of rotating driver feedback signs in addition to the 40
existing permanent driver feedback signs. Staff also plans to purchase eight more permanent
signs to complete the goal of covering every public school roadway frontage, which will bring
the total to 48.
The Speed Management Program Resolution incorporates the direction from these nine discussion
questions and the Program developed by Toole Design Group, CSAC, community engagement and
City Council.
Next Steps
Details of the Program’s next step by quarter are listed below with updates to the June 6, 2023 memo
shown in green.
Projected Implementation – Q2 2023
• The Police Department will conduct regular speed and noise enforcement campaigns. Based on
identified community concerns, the Police Department will conduct increased enforcement in
Resolution 57-23 – Approving the City Of Dublin’s Speed Management Program And Repealing The City’s
Current Traffic Calming Policy
July 25, 2023
Page 6 of 7
specific areas of the City (i.e. Riverside Drive, Bridge Park, I-270, etc.). The Police Department will
inform the community of the enforcement efforts prior to beginning increased enforcement in
specific areas.
• The Police Department will emphasize speed enforcement in school zones and neighborhood
roadways based on the presence of vulnerable roadway users and lower allowable speeding
thresholds.
• In furtherance of increasing traffic safety and intelligence-led, proactive traffic enforcement,
the Police Department will ensure that recent traffic complaints and high crash areas are
discussed daily so all officers know where community members are asking for assistance with
traffic complaints and where they can focus their enforcement efforts.
• The Police Department will personally follow-up with each resident who submits a concern
regarding speed management, regardless of which City division receives the concern.
Projected Implementation – Q3 2023
• Staff proposes that Code Sections 72.130 and 72.131 be repealed and superseded with the
adoption of a Speed Management Program Resolution at the July 31, 2023 City Council
meeting.
• Staff will bring forward legislation to City Council to establish the Bridge Street Business
District.
• Develop a media campaign toolbox and strategy project.
• Add enforcement metrics and a speed management dashboard displayed on the City’s website for
transparency and showing the progress of the program.
• The Police Department will work with the Ohio State Highway Patrol Aviation Unit to conduct
enforcement campaigns with zero tolerance for excessive speed, street racing, reckless operations,
and operating a motor vehicle while intoxicated (OMVI) on I-270 and US-33.
• As directed by Council, begin engaging residents regarding installing speed cushions on Cacchio
Lane and depending on the resident feedback and engagement process, speed cushions
could be installed as early as Q3 2023.
• Staff will include funding for speed safety cameras in the upcoming Q3
Supplemental Appropriations Ordinance.
Projected Implementation – Q4 2023
• Based on Council direction, staff will develop up to three tactical urbanism concept plans and
install the pilot projects which will be highly dependent on resident feedback, to create an
effective tool and to build a successful program.
• Purchase initial set of speed safety cameras and begin issuing warning letters.
• Staff will request annual funds to implement speed management program initiatives (i.e.
rotating driver feedback signs, speed safety cameras, tactical urbanism projects, etc.) as part
of the CIP.
Projected Implementation – Q2 2024
• Based on outcome of tactical urbanism pilot projects, create guidelines and design criteria for a
toolkit to be used on tactical urbanism projects for citywide neighborhood driven implementation.

Recommendation
Staff recommends approval of Resolution 57-23 Speed Management Program, and repealing
Sections 72.130 and 72.131 of the City Codified Ordinances, 2004 Traffic Calming Policy.
Speed Management Program
The Speed Management Program will
provide a framework for a data-driven
approach to speed management.
The program goals strive to create safe
and comfortable streets for all residents
and road users across Dublin including
people walking and rolling.
Speeding concerns will fall into one of three categories in this Program. Police and Transportation &
Mobility Staff will determine the appropriate speed management category by calculating the eighty-fifth
(85th) percentile speed minus the posted speed and/or identifying results that have more than one percent
of traffic traveling at excessive speeds. These categories will be used to select context appropriate speed
management solutions as defined below:
The Vision Statement of the
Speed Management Program
Speed Management Program | Dublin, Ohio | July 2023
The Goals of the Speed
Management Program
1. Reduce traffic-related fatalities
and serious injuries in the City
of Dublin for all roadway users,
including those walking and rolling.
2. Reduce excessive speeding across
Dublin. Excessive speeding is
defined as traveling more than 15
mph over the speed limit.
3. Develop strategies to address
speeding concerns on Dublin streets.
Speed Management Categories
This Program uses a three step process for each speeding concern received.
Step 1. Collect data and educate
Speed Management Program | Dublin, Ohio | July 2023
Speed Management Program Steps
Speed data will be collected when there is a resident
or City staff concern.
A resident request
•Can be submitted through any format, such as the
GoDublin app, email, website or phone.
A city staff concern can include, but is not limited to:
•Roadway has been identified as a high crash
corridor based on a review of fatal and serious
injuries crashes within past five (5) years,
•Police Maintenance Zone,
•Review of speed citation data,
•Review of speed-related crashes
Speed data will be gathered in response to both
request types. Data collected within the past eighteen
(18) months will be considered current, if there
hasn’t been a change to the roadway network or
development in the area.
All traffic concerns are documented and investigated
by officers. If a call is received from a resident
that requires immediate follow up, an officer is
dispatched to speak with the resident and/or address
the concern. If the complaint involves a recurring
speed issue, a member of the police department
traffic enforcement unit will conduct a follow up
investigation. During the investigation, officers
contact the complainant to obtain further information.
Residents will receive a response that the request
has been initiated and information regarding the
Speed Management Program.
Residents have access to the Education and
Awareness Solutions within the Speed Management
Toolbox beginning in this step of the Speed
Management Program.
Step 2. Police and Transportation & Mobility
Staff evaluate results and determine the speed
management category
Police and Transportation & Mobility Staff evaluate
results and determine the speed management
category as defined in the Speed Management
Categories section.
Every odd month (January, March, May, etc), staff
will publish results from recently completed speed
surveys with the identified speed management
category. Residents who initiated requests will be
notified.
Step 3. Use the speed management toolbox and
implementation guide to select appropriate
solutions
The speed management toolbox will be used to
identify appropriate solutions for each category
of request. The speed management toolbox and
implementation guide will be maintained and updated
by the Division of Transportation & Mobility.
In addition, the Traffic Enforcement Action Policy
(attached) will be used by the Police Department to
provide guidance to officers enforcing speed limits,
focusing on the following areas:
•Serious Injury or Fatal Crash Areas
•Neighborhoods generating complaints
•School zones
•Areas identified from formal speed complaints
•Official business districts
•Maintenance zones
Speed Management Program | Dublin, Ohio | July 2023
Category 1 and Category 2 will be assigned speed
management solutions that can be implemented
by the Division of Transportation & Mobility and
Police. Police will lead the placement of the Mobile
Speed Trailers, the Police Observations and Resident
Engagement, and any other items in blue font in the
Speed Management Toolbox.
•City staff will update the Speed Management
webpage with the selected speed management
tool for Category 1 and Category 2 projects
every quarter, or sooner. If a route qualifies for
a speed management solution, the resident
who initiated the request will be notified of the
selection solution, and an estimated date for
implementation.
The map of ineligible streets in the Implementation Guide shows the streets in Dublin that do not qualify for most
of the horizontal measures or any new vertical deflections listed in Category 3 of the Speed Management Program,
but other types of solutions are possible. Some of these routes have existing measures that do not need to be
removed, but will not receive additional measures. The list was developed in conjunction with the Washington
Township Fire Department and the City of Dublin Police Department.
Ineligible Streets
Speed Management Program Steps (Continued)
Category 3 streets will be reviewed on a case-by-
case basis to determine the appropriate speed
management solution. These solutions will likely
require specific funding through the Capital
Improvements Program or other sources. Residents
who initiated requests will be notified.
1.Implement appropriate Category 2 solutions
prior to implementing Category 3 solutions to
determine if the Category 2 solutions resolve
the issue. If the issue is not resolved, staff will
determine the appropriate Category 3 solution.
2.If High Visibility Enforcement is a selected
solution, Police will lead this effort.
3.Conduct a road safety audit or corridor study and
engage with neighborhood residents, city staff,
emergency services and other stakeholders to
best understand the speeding and safety issues.
Engagement should consider all modes including
people walking, bicycling, driving, accessing
transit, etc.
4.Select speed management solutions from the
implementation guide based on street function
and street type. Assess the overall expected crash
reduction and speeding reduction with crash
modification factors using national, state or local
resources to determine if selected solutions are
likely to meet the project goals.
5.Seek neighborhood feedback on recommended
speed management plan.
6.If necessary, determine appropriate funding
source and submit project for funding
consideration, through the Capital Improvements
Program or other source. Staff will also take
advantage of maintenance and operations
opportunities to consolidate design and
construction activities.
Speed Management Program | Dublin, Ohio | July 2023
Speed Management Program Example
1.A resident enters a speeding concern through
the GoDublin app for their 25 mph speed limit
residential street named Nospeeding Drive.
2.Staff reviews the speed data collected within the
past 18 months, and does not find a recent survey
3.Staff collects speed data for the street.
4.An officer contacts the resident to discuss the
concern.
5.The resident is provided the option to pursue the
Education and Awareness Solutions, regardless of
the speed survey results.
6.The speed survey results are reviewed, as shown
in the example below:
7.The two metrics used to determine the Speed
Management Category are the 85th percentile
speed and the percent of excessive speeds.
8.The 85th percentile values is compared to Table 1
for a 25 mph local street:
a. 85% speed over speed limit calculation:
28.67 – 25.00 = 3.67 mph
b. Round up to 4 mph over posted speed limit
c. Category 2 solutions would apply
9.The excessive speed percent is compared to one
percent, as defined in Category 3:
d. Percent of excessive speeds: 0.1%
e. Does not result in one or more percent of
motorists
10.Staff publishes the results with the speed category
and notifies the resident.
11.The Speed Management Toolbox is reviewed
by Police and Transportation & Mobility staff to
determine the most appropriate solution(s).
12.The planned solution for Nospeeding Drive could
include solutions from Categories 1 and 2, such
as a Public Awareness Campaign, rotating driver
feedback signs and Police observations and
engagement. These solutions will be added to
the website and the resident will be notified and
provided a timeframe for implementation.
Speed Management Toolbox
Education and Awareness Solutions
Speed Management Toolbox | Dublin, Ohio | July 2023
Public Awareness Campaigns can be messaged
through a variety of communication tools such as
social media, email, fliers, newsletters, and signs to
help others understand how small changes can make
a big difference.
Police Loaner Laser Program allows residents to
be trained to use a handheld laser gun to measure
speeds of traffic on a roadway.
Police Ride Along Program invites a resident to ride
along with an officer based on interest.
Yard signs are a trend in grassroots speed
management efforts. Neighbors can take action
by placing a sign in their yard to encourage slower
speeds, through coordination with their HOA or Civic
Association. The effectiveness of yard signs will be
evaluated as the program progresses to determine if
this is a viable part of the Program.
Category 1 Solutions
Public Awareness Campaigns can be messaged
through a variety of communication tools such as
social media, email, fliers, newsletters, and signs to
help others understand how small changes can make
a big difference.
Mobile Speed Trailers can be moved to requested
locations by the Police Department to increase driver
awareness and improve speed limit compliance. All
traffic concerns are documented and investigated by
officers. If a call is received from a resident that
requires immediate follow up, an officer is dispatched
to speak with the resident and/or address the
concern. If the complaint involves a recurring
speed issue, a member of the police department
traffic enforcement unit will conduct a follow up
investigation. During the investigation, officers
contact the complainant to obtain further information.
Similarly, Rotating Driver Feedback Signs can be
placed on residential streets for two to four week
periods.
Blue text indicates Police led activities throughout the toolbox.
Speed Management Toolbox | Dublin, Ohio | July 2023
Category 2 Solutions
Public Awareness Campaigns, Mobile Speed Trailers
and Rotating Driver Feedback Signs can be used, as
applied in Category 1.
Permanent Driver Feedback Signs may be considered
on Non-Local streets and a presence of fatal or severe
injury pedestrian/bicycle crashes within the past 5
years, and/or within 500-feet of a high presence of
vulnerable users, a school, community center, or
community parks.
Police Observations and Engagement with
Community Members can improve driving behaviors,
particularly within neighborhoods. Officers observe
the driving conditions in a marked police vehicle,
speak with resident that initiated the request,
and may lend out a handheld radar or laser speed
reader, as resources allow. All traffic concerns are
documented and investigated by officers. If a call
is received from a resident that requires immediate
follow up, an officer is dispatched to speak with the
resident and/or address the concern.
If the complaint involves a recurring speed issue, a
member of the police department traffic enforcement
unit will conduct a follow up investigation. During the
investigation, officers contact the complainant to
obtain further information.
Speed Safety Cameras can be used to send drivers
warning letters to reduce their speed on targeted
streets.
Tactical Urbanism Solutions:
1. Street Width Reduction Using Pavement
Markings visually narrows the roadway, and helps
to reduce speeds. This can be done in a variety of
ways, including marking on-street parking spaces
(as shown in the example below) or by adding a
wide edge line to any street type, including curb
and gutter.
2. Stamped and Colored Asphalt can be used for
emphasizing crosswalks or pavement other areas.
3. Other tactical urbanism solutions, such as street
trees, are also included in Category 2.
Speed Management Toolbox | Dublin, Ohio | July 2023
Category 3 Solutions
Review and implement appropriate Category 2
solutions before considering the Category 3 solutions
below:
High Visibility Enforcement can be considered to
provide awareness and improve speed compliance, as
a Category 3 solution. Police resources and strategies
in Category 1 – Mobile Speed Trailers and Category
2 – Police Observations and Engagement with
Community Members can also be considered under
Category 3. All traffic concerns are documented
and investigated by officers. If a call is received from
a resident that requires immediate follow up, an
officer is dispatched to speak with the resident and/
or address the concern. If the complaint involves
a recurring speed issue, a member of the police
department traffic enforcement unit will conduct
a follow up investigation. During the investigation,
officers contact the complainant to obtain further
information.
Signs and Markings including additional speed limit
signs and words on pavement, such as 25 MPH
markings can be applied to improve driver awareness.
Horizontal Measures that change curb lines and
reduce pavement width to reduce speeds can include
chicanes, traffic circles, roundabouts, landscaped
medians, and curb extensions. These features
also improve conditions for pedestrians and other
vulnerable users by reducing their exposure to traffic.
Streetscape Improvements, such as Pavers or
Stamped and Colored Asphalt can be used to add
emphasis to crosswalks or delineate parking lanes.
Changing the material of a parking area will visually
narrow the adjacent travel lane. Other streetscape
solutions are also available.
Street Width Reductions may include reducing the
lane width or number of lanes by adding pavement
markings or physically narrowing the pavement.
Narrower pavement generally improves speed
compliance.
Technology Solutions such as speed limiting signal
timings, automated data collection tools, along
with existing and emerging technologies can be
considered. Innovations in this area may allow the
City to provide targeted mailings to remind drivers to
watch their speed. Connected Dublin initiatives may
also be integrated, as opportunities allow.
Speed Safety Cameras can be used to send drivers
warning letters to reduce their speed on targeted
streets.
Vertical Measures such as speed cushions should
only be considered if other measures have been
unsuccessful. If after at least one Category 3 Speed
Management Solution has been tried and proven to
be ineffective, and speeds are still in Category 3, then
vertical measures will be evaluated as described in
Step 3 of the Speed Management Program.
Speed Management
Implementation Guide
Speed Management Implementation Guide | Dublin, Ohio | July 2023
The implementation guide should be used to evaluate if a solution is appropriate for the street environment, using
the functional classification, special street type (emergency or transit route), and speed management category,
based on the measured data. The chart is also a reference for the overall expected speed reduction.
Speed Management Implementation Guide | Dublin, Ohio | July 2023
The Federal Highway Administration (FHWA) and the Institute of Transportation Engineers (ITE) recommend not
installing vertical measures on roadways that are primary or routine emergency vehicle routes, or on streets with
public transit. The following map shows the streets in Dublin that do not qualify for most of the horizontal measures
or any new vertical deflections listed in Category 3 of the Speed Management Program, but other types of
solutions are possible, including, but not limited to, technology, pavement markings, striping, and/or high visibility
enforcement. Some of these routes have existing measures that do not need to be removed, but will not receive
additional measures. The list was developed in conjunction with the Washington Township Fire Department and
the City of Dublin Police Department.
Ineligible Streets
