Description of Slide 29. Section 6 – Developing TMPs for Projects

Flowchart for planning and design, construction, and assessment

Description

This flow chart is composed of three main stages: planning and design, construction, and performance assessment.

The planning and design stage contains steps 1 through 9.

Step 1 is to compile project material. This step includes:

  • Project definition and scope
  • Construction staging approaches
  • Preliminary management strategies

Step 2 is to determine TMP needs and determine if they are for a significant project. Technical specialists contribute to both steps 1 and 2, and applicable policies contribute to step 2.

Step 2 needs to assess expected work zone impacts of projects. If these impacts are not for a significant project, the determination leads to a basic TMP (TTC) and an intermediate TMP (TTC of TO, PI as appropriate). If these impacts are for a significant project, the determination leads to a basic TMP (TTC), an intermediate TMP (TTC of TO, PI as appropriate), and a major TMP (TTC, TO, PI).

Step 2 leads to step 3, which is to identify stakeholders. This step and the basic TMP determined in step 2 are used to reach step 4.

Step 4 is to develop TMP. This step can be basic, which is to prepare a TTC plan, or intermediate or major, which is to:

  • Analyze work zone impacts
  • Draft management strategies
  • Estimate implementation costs
  • Solicit review and comments

Technical specialists contribute to the basic development, and applicable policies contribute to the intermediate or major development.

Step 4 can lead to step 5, which goes back to step 1, or step 4 can lead to step 6, which is to finalize construction phasing and staging and TMP. Step 5 includes:

  • Agency approval of TMP
  • Stakeholder buy-in.

The construction stage contains steps 7 through 10.

Step 7 is re-evaluate and revise TMP as needed. This step includes:

  • Agency approval of TMP revisions
  • Implementation cost

Step 7 leads to step 8, which is to implement TMP.

Step 8 leads to step 9, which is TMP monitoring. This step is composed of monitor mobility, safety, and community impacts, and management strategy effectiveness. Applicable policies and performance requirements also contribute to step 9. Step 9 can lead back to step 7.

The performance assessment stage contains step 11, which is post-project evaluation and leads to policies and procedures.
