TMP Development
Module 7
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 internallyTMP CoordinatorPlanningDesignTraffic engineeringConstructionOperations (maintenance)?
Step 1 - Compile Project MaterialStaff 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.
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.
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.
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.
Step 2c - Major TMP - Significant ProjectsMajor 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.
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.
Step 4 – Develop TMPThe 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.
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.
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
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.
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.).
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?
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.
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.

Other Considerations

Reduced at all times? Reduced when workers present and exposed? Use of Law Enforcement?
Use of Positive Protection – PCB or other 23 CFR 630 Subpart K
MUTCD Sec 6C.01
“Reduced speed limits should be used only in the specific portion of the TTC zone where conditions or restrictive features are present…A TTC plan should be designed so that vehicles can reasonably safely travel through the TTC zone with a speed limit reduction of no more than 10 mph.”

TMP Overview 53
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
TMP Overview 54
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
