1 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 Development Process 1

2 TMP Development, Implementation, and Assessment 11 Step Process 1. Compile Project Material 2. Determine TMP Needs 3. Identify Stakeholders 4. Develop TMP 5. Update/Revise TMP 6. Finalize Construction Phasing/Staging and TMP TMP Development, Implementation, and Assessment 11 Step Process (continued) 7. Re-evaluate/Revise TMP 8. Implement TMP 9. TMP Monitoring 10. Update/Revise TMP Based on Monitoring 11. Post-Project TMP Evaluation 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)? 2

3 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. 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. 3

4 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 d 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 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. 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. Contractor Federal Agencies Emergency Responders DOT TMP Property Owners Road Users Local Government 4

5 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. 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 5

6 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? 6

7 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.

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. 10
