Transportation Management Plans (TMPs)


  1. A set of coordinated transportation management strategies
  2. A description of how the strategies will be used to manage work zone impacts

Components include:

  • Traffic Control Plans
  • Public Information and Outreach
  • Transportation Operations
  • Incident Management

slide 4

WisDOT TMP Process

  • Includes all phases of project development
    • Planning
    • Design
    • Construction
  • Adjust at various construction stages
  • Identify issues and impacts
    • Work Zone Impacts Assessment

WisDOT TMP Process

  • Determine TMP Type
  • Identify and Evaluate Strategies
  • Develop TMP Report
  • Include with Design Study Report (DSR)
  • Approval Process
