What is a TMP? Set of coordinated transportation management
strategies applied to manage work zone impacts of the project
Scaleable projects with larger anticipated impacts may require more
strategies Required in all FA projects TMP=TCP in some projects
TMP=TCP+TO+PI components in others

TMP Team Approach Better coordination throughout the process
from development to implementation Involve all involved offices
internally TMP Coordinator Planning Design Traffic engineering
Construction Operations (maintenance)?
Slide 7
Step 1 - Compile Project Material Staff responsible for each
stage of the project (planning, preliminary engineering, design,
construction) begins by compiling available project materials such
as: Project definition Construction phasing/staging alternates
Preliminary work zone management strategies. Preliminary cost
estimates for strategy implementation Information from other
projects in the corridor to evaluate the combined or cumulative
impact of the projects.
Slide 8
Step 2 - Determine TMP Needs Necessary Components of TMP Impact
assessment Duration of project Possible Strategies Determine if it
is a significant project: Based upon the agency's policy and
procedures, project's anticipated work zone impacts.
Slide 9
Step 2a - Basic TMP Basic TMPs Applied on construction or
maintenance projects with minimal anticipated impacts Projects
typically only involve the development of a TCP layout of devices,
phases, etc.
Slide 10
Step 2b - Intermediate TMP Intermediate TMPs Used for
construction or maintenance projects that are anticipated to have
more than minimal disruption, but have not been identified as
significant projects. Include more detailed work zone impacts
analysis and management strategy information than Basic TMPs,
including some element of PI and/or TO strategies as well as
TCP.
Slide 11
Step 2c - Major TMP - Significant Projects Major TMPs are
intended for significant projects. Major impacts to road users,
residents and businesses TMPs for significant projects shall
consist of a TCP, and also address PI and TO components. In
addition to the TMP components required by the Rule, TMPs may also
contain cost estimates, coordination strategies between
stakeholders, secondary mitigation strategy(s), analysis of
potential impacts on detour routes, and analysis of the potential
effects of the management strategies.
Slide 12
Step 3 Identify Stakeholders Internal and external that can
provide valuable input to the agency on what strategies to include
in the TMP to help manage the work zone impacts of a project. TMP
DOT Road Users Local Government Property Owners Emergency
Responders Federal Agencies Contractor
Slide 13
Step 4 Develop TMP The level of detail of the TMP during early
planning is largely dependent upon the type of planning activity,
the expected impacts of the project, and the availability of data.
At a minimum, early planning should entail a qualitative exercise
to list the potential impacts of a project, along with a list of
potential management strategies, and the expected costs of those
management strategies.
Slide 14
Step 5 Update/Revise TMP The TMP is updated or revised as the
project progresses through its various developmental stages as more
project-specific information becomes available.
Slide 15
Step 6 Finalize Construction Phasing/Staging and TMP PS&Es
shall include either all the applicable elements of a TMP, or the
provisions for a contractor to develop a TMP. TMP development
should begin prior to project letting, even for design-build
projects. Some elements could be accomplished early in process
alternate route work or beginning of PI plan Some may not be in
PS&E agency in house
Slide 16
Step 7 Re-evaluate/Revise TMP If alternative construction
phasing/staging plans or other management strategies have been
suggested, technical specialists from the contractor or agency need
to review the TMP to see if changes are needed.
Slide 17
Step 8 Implement TMP The TMP is implemented. In some cases,
components of the TMP may need to be implemented prior to
construction (e.g., public relations campaign, improvements to
detour routes, etc.).
Slide 18
Step 9 TMP Monitoring Monitor operational performance of work
zone during the construction phase Are predicted impacts realistic?
Are the strategies in the TMP effective in managing the impacts? Do
any adjustments to TMP need to be initiated?
Slide 19
Step 10 Update/Revise TMP Based on Monitoring If performance
requirements are not met, the agency and/or contractor should
revisit the TMP and consider alternate management strategies and/or
phasing/staging approach(es) that meet the approval of the
agency.
Slide 20
Step 11 Post-Project TMP Evaluation TMP performance assessment
can aid in addressing the following concerns: Which management
strategies have proven to be either more or less effective in
improving the safety and mobility of work zones? Are there
combinations of strategies that seem to work well? Should TMP
policies, processes, procedures, standards, and/or costs be
adjusted based on what has been observed or measured? Are the best
decisions in planning, designing, implementing, monitoring, and
assessing work zones being made? Performance assessment may involve
two tracks: 1) the overall TMP process 2) actual field performance
of the work zone and TMP.

TMP Overview53 Summary Estimate and budget for TMP development
and implementation early in project development (update as
appropriate throughout project) Consider and address WZ impacts
from a broad transportation management perspective (rather than
solely a traffic control perspective) Coordinate with key parties
to jointly identify WZ impacts issues to account for and management
strategies to address them Strive to use strategies that keep lanes
open, especially during peak traffic times
Slide 54
TMP Overview54 Summary (cont.) Consider using extended closures
or full closures versus numerous night closures Consider strategies
that facilitate decision-making by the public to avoid the WZ
(e.g., public awareness, advance signage in locations prior to key
motorist decision points) Training is important for all personnel
involved in TMPs Management support is needed for effective TMP
efforts
