Table of Contents
This section provides an overview of the project, which generally includes:
- Work zone limits (if possible, include a map showing the limits of the work)
- Project background information
- Overview of roadways directly affected by project work zones
- Specific traffic restrictions expected on major roadways during the work (e.g., shoulder closures, lane closures, lane shifts)
- Regional projects that may impact each other
- Project Schedule.
This section includes contact information and roles and responsibilities of major personnel involved in the project such as:
- TMP Development Managers—Agency/Contractor personnel who have primary responsibility for developing the TMP.
- TMP Implementation/Monitoring Managers—Agency/Contractor personnel who have primary responsibility for implementing and monitoring the TMP.
- TMP Implementation Task Leaders—Responsible for managing, completing, overseeing, or assisting in specific transportation management tasks during the work.
- Emergency Contacts—Public and semi-public agencies, such as hospitals, schools, health clinics, etc., who must be kept informed about the work zone activities, especially in case of a road closure.
The following tables can be used to list the contact information and roles and responsibilities for major personnel involved in the project. Tables can be modified depending on agency needs.

As challenges vary greatly from one project to another, a preliminary assessment of work zone impacts developed in the early planning stages of the project will help identify issues or uncover problem areas that should be considered during project development. Agency guidelines apply on determining the impact levels and how extensive the preliminary assessment should be. Some agencies use decision-support tools, while others have developed checklists/flowcharts to assist in the decision-making process.
Some of the potential questions that could help in the preliminary assessment of work zone impacts include:
Does the project includes a long-term closure and/or extended weekend closure?
If Yes, what is/are the applicable type of facility(ies)?
- Principal Arterial
- Minor Arterial
Can traffic be detoured?
- Is the local alternate detour route in good condition?
- Will the detour route have a detrimental impact on emergency vehicles, school buses, or other sensitive traffic?
- Are there load limit restrictions on the detour?
- Are there bridge/culvert height or width restrictions on the detour?
Is the existing shoulder sufficient to support traffic during construction?
Is additional width required on culverts or bridges to maintain traffic?
Is there a pedestrian/bicycle facility that must be maintained?
Would a temporary structure(s) be required?
Would a median crossover be needed?
Would there be a need to maintain railroad traffic?
Could maintenance of traffic have an impact on existing or proposed utilities?
Does it appear that maintenance of traffic will require additional right-of-way?
Can the contractor restrict the roadway during the time periods listed?
- a.m. peak hours, one direction
- p.m. peak hours, one direction
- a.m. peak hours, both directions
- p.m. peak hours, both directions
- Local celebrations
- Holidays or weekends
- Sporting events/other special events
Will project timing (for example, start or end date) be affected by special events:
- School closings or openings?
- Sporting events?
Are there any projects to be considered along the corridor or in the region?
- Roadwork in the immediate area that may affect traffic or the contractor's operations?
- Roadwork on other roads that may affect the use of alternate routes?
Are there other maintenance of traffic issues? If so, specify.
Some projects (e.g., on low volume rural roads) may need only a simple screening tool such as a checklist, while others (e.g., in congested urban areas) may need quantitative analysis (level of service analysis, signal timing, etc) to determine the impact levels. Quantitative analysis may indicate the need for some additional analysis and/or strategies to assess and manage the impacts, or it may indicate that impacts are relatively low and few strategies are required beyond the temporary traffic control (TTC) plan.
NOTE: If the project is expected to create moderate-to-major impacts, use Template 2. For lower impacts projects, continue with this template.
This section provides an overview of various strategies employed to improve the safety and mobility of work zones and reduce the work zone impacts on communities and businesses. The strategies are grouped according to the following categories:
- Temporary Traffic Control (TTC)
- Transportation Operations (TO)
- Public Information and Outreach (PI&O).
TMP Details—Many agencies have the details of proposed work zone strategies in TTC plans (e.g., PCMS message content) and strategies listed in the TMP document. In such cases, it will be useful to include the detailed plans (e.g., TTC Plan) as attachments to the TMP.
TMP Costs—Agency guidelines apply regarding whether cost should be shown in the TMP document. If the TMP is to be a contract document, it typically does not show cost items. However, estimating the work zone management strategy implementation costs and including these within the overall project budget is crucial, as it may be difficult to obtain additional funding at a later time. This potentially avoids under-allocation of funds. Where feasible, it is helpful to itemize the cost estimates for the various management strategies and document them in the TMP, and specify cost responsibilities, opportunities for sharing or coordinating with other projects, and funding sources. TMP components can be funded as part of the construction contract and/or in separate agreements.
The sample tables below provide a summary of various work zone management strategies. They can be modified by agencies to suit their needs.

Any additional notes on selected strategies, the TMP in general, or any item requiring special attention for the project can be provided in this section.
Agency requirements for TMP implementation and monitoring can be included here. The responsible personnel for TMP implementation and monitoring can be identified in Section 2.0—Roles and Responsibilities.
Monitoring performance of the TMP during the construction phase is important in establishing whether the predicted impacts closely resemble the actual conditions in the field, and whether the TMP strategies are effective in managing the impacts. According to 23 CFR 630 Subpart J §630.1012(e), the State/Agency and the contractor shall each designate a trained person at the project level who has the primary responsibility and sufficient authority for implementing the TMP and other safety and mobility aspects of the project.
TMPs, and changes to TMPs, must be approved by the DOT before they are implemented. A sample TMP Approval Template is given below which can be modified by agencies according to their practice/needs.
