  • Transportation Management Plans (TMP)
    • Temporary Traffic Control Plan (TTCP)
      • Includes: maintaining traffic special provision, typicals, plans, etc.
    • Transportation Operations Plan (TOP)
      • Plans for transit issues, maintaining non-motorized traffic, traffic signal coordination, proposed mitigation measures, etc.
    • Public Information Plan (PIP)
      • How will the public be informed and through which media, media campaigns, newspapers, billboards, etc.


slide 5

What is a Significant Project?

  • Work Zone Travel Time Delay Greater than 10 minutes
  • Volume to Capacity greater than 0.8
  • Level of Service D or lower or if the roadway LOS has changed from LOS of A to C


slide 6

Work Zone Safety and Mobility Construction Projects

  • Non-Significant Project
  • Projects that do not exceed the mobility criteria thresholds
  • TTCP Required
  • TOP and PIP Recommended



slide 7

Photo of a lane shift sign.

Work Zone Safety and Mobility Construction Projects

  • Significant Project
    • Projects that exceed one or more of the mobility criteria thresholds (volume to capacity ratio, level of service, travel time delay)
    • TTCP, TOP and PIP Required
    • Statewide Peer Review is Required


slide 8

Photo of a set of yellow impact attenuator barrels surrounding the terminus of a jersey wall used to separate the throughway from a closed shoulder.

Statewide Peer Review Team (SPRT)

  • Reviews all projects that are identified as significant
  • Project Rating system
    • Standardized review form
    • Red, Yellow, Green Ratings
    • Executive level engagement


slide 9

When are the TMP Submitted?

TMP's are to be submitted to the Operation Engineer after the Plan Review (80% complete) and before the Error & Omission Conference (EOC) (100% complete)



slide 10

Who is on the Statewide Peer Review Team (SPRT)?

Image of a map of Michigan identifying the seven regional areas with representatives on the peer review team. The identified areas are the Superior, North, Grand, Bay, Southwest, University, and Metro regions.



slide 11

Who is on the Statewide Peer Review Team (SPRT)?

  • Statewide work zone administrator (Chairperson)
  • The remaining team is rotating
    • TSC manager
    • Development engineer
    • Delivery engineer
    • Traffic and safety engineer/technician
    • Region Engineer


slide 12

Work Zone Safety and Mobility

  • Statewide Peer Review Team (SPRT)
    • Benefits:
      • Check and balance for mobility issues
      • Feedback from other areas
      • Statewide Work Zone Administrator provides consistency
      • Allows for sharing of Best Practices

Work Zone Safety and Mobility

Aerial photo of final construction phase of a reconstructed overpass.
  • Temporary Traffic Control Plan (TTCP) items reviewed:
    • TTCP is reasonable and logical with the project duration and traffic volumes
    • Staging & Constructability is reasonable and well thought out
    • Project is compared to similar projects
    • Alternative analysis is done with comparison in Benefit/Cost
    • Crash analysis done for the location and compared to similar projects
    • Monitoring Plan for safety & Mobility
    • Contractor Ingress & Egress is addressed


slide 14

Photo of a road widening project featuring a work truck on the newly paved shoulder separated from through traffic by a line of traffic barrels.

Work Zone Safety and Mobility

  • Transportation Operations Plan (TOP) items reviewed:
    • Delay mitigation techniques applied appropriately
    • Maintain pedestrian, local transit and non-motorized traffic
    • Emergency Responder access
    • Commercial Vehicle access
    • Project combined or bundled
    • Corridor Impacts


slide 15

Work Zone Safety and Mobility

Photo of a work zone sign providing two sets of travel times advising travelers how long it will take to reach an interchage, one via I-275 and the other via I-94.
  • Public Information Plans (PIP) items reviewed:
    • Is the public outreach appropriate for the project and scale of impact
      • MiDrive
      • Brochures
      • List Serves
      • Public Construction Kickoff Meetings
      • Social Media
      • Advance Notice/Delay Signs
    • Is the list of stakeholders comprehensive

TMP Rating

  • Green: Proceed, Review SPRT comments
  • Yellow: Proceed, Review SPRT comments; Project Office incorporate changes as appropriate. Feedback from Project Office is required
  • Red: Do not Proceed, Review SPRT comments; Region Engineer to discuss with Chief Operation Officer


slide 17

Challenges with TMP Reviews

  • How and When do we do a TMP Review with Design Build Projects
  • Quick turn around for Value Engineering Proposals
    • Have done an email Peer Review Team for this
