Work Zone Significance Determination

State PE Number:	Route/From-To:
PIN:	County:
Analyst:	Project/Construction AADT:

This is an	Initial Secondary determination of the project’s significance.

Major Route Criteria

A project lasting at least three days on an interstate route within a TMA with intermittent or continuous lane closures
A project where all lanes in one direction will be closed on (a) any interstate route or (b) a non-interstate route having an AADT of at least 50,000 vpd
Yes, by the Major Route Criteria, this is a Significant Project.
No, the Major Route Criteria are not met.

Delay Criteria

Urban	Rural	Freeway	Arterial	Collector/Other
No. of lanes (in one direction) to be open in work zone:	Max. Allowable AADT (24-hr, two-way) from Table 3.1:
Yes, by the Delay Criteria, this is a Significant Project (project AADT > max AADT).
No, the Delay Criteria are not met (project AADT < max AADT).

Qualitative Criteria

Rate the following aspects of the work zone:

High	Low
Business impacts (how many businesses affected?)
Public Interest
Exposure impacts due to long project duration
Impacts due to alternate routes
Impacts due to other concurrent projects nearby
Concurrent project description:
Other:
Yes, due to extraordinary Qualitative Criteria, this is a Significant Project.*
No, the Qualitative Criteria are not met.
* “Significance” based solely on Qualitative criteria to be carefully considered and approved by responsible Division Director

FINAL TMP DETERMINATION:	Significant Project:	Yes	No

TMP Exception

Per FHWA/TDOT guidelines, an EXCEPTION has been applied for and approved by the FHWA Division Office (attach appropriate documentation)

Statement of Categories of TMPs

Significant Project - Requires careful consideration of work zone impact mitigation. Requires use of strategies from all three of TMP categories to help mitigate the impacts of a significant project:

Temporary Traffic Control Strategies (TTC)

Transportation Operations Strategies (TO)

Public Information Strategies (PI)

A Significant Project is one for which any of the following criteria exists:

Any project on the interstate system located within a recognized Transportation Management Area (TMA) that occupies a given location for at least three days duration with either continuous or intermittent lane closures. For the purposes of this Manual, it is assumed that the TMA consists of the following counties: Blount, Bradley, Carter, Davidson, Fayette, Grainger, Hamblen, Hamilton, Hawkins, Jefferson, Knox, Loudon, Madison, Maury, Montgomery, Robertson, Rutherford, Sevier, Shelby, Sullivan, Sumner, Washington, Williamson, Wilson.

Any project of any duration on an interstate route, or any other route with an ADT of at least 50,000 vehicles per day for which all lanes in one direction will be closed to traffic.

Any project for which the delay through the limits of the work zone is at least 30 minutes above the normal delay under typical non-work conditions.

Any project deemed Significant by extraordinary qualitative characteristics. This determination may be made on the basis of conditions such as high levels of public interest, business/community impacts, or long work zone duration. All Significant Projects defined in this manner shall only be done with careful consideration and strategic decision making.

For a “non-significant” Project, one of two different levels of TMPs may be developed. A Basic TMP is to be used when only a TTC plan is needed to successfully implement a safe and efficient work zone. An Intermediate TMP is to be completed for “non-significant” projects where public information and/or transportation operation strategies would be beneficial or necessary as determined based on TDOT decision-making practices and procedures.

Intermediate Project - Requires additional planning, coordination, etc., but not required to be at the same level of a Significant TMP. TMP requires use of PI and/or TO strategies beyond the project’s TTC strategies. It is expected that the majority of Intermediate projects will consist of TTC and PI strategies.

Basic Project - Typical work zone TTC plan is implemented alone. Refer to TDOT standard drawings, standard notes, and MUTCD. No additional TMP strategies required.

Temporary Traffic Control Strategies

The Temporary Traffic Control component of the Transportation Management Plan (TMP) is included in the Contract Documents. The various strategies described below are intended for use in developing the final TMP. Although many of these strategies are routinely included in the Temporary Traffic Control Plan, they are provided here for review and consideration.

Construction phasing and/or equipment staging

Full roadway closure

Narrow lane/shoulder widths to maintain existing number of lanes

Full closure of lane/shoulder

Lane shift to shoulder/median

One-lane, two-way operation

Two-way traffic on one side of divided roadway

Reversible lanes

Ramp closure/relocation

Directional interchange closure

Work hour restrictions (off-peak, night, weekend)

Bike/Ped access maintenance

Private property/business access maintenance

Off-site detour/alternate routes

Temporary guidance/informational signs

Portable changeable message signs

Flashing arrow boards

Flaggers/uniformed traffic control personnel

Temporary traffic signals

Warning lighting devices

Coordination with other construction projects

Coordination with other utility projects

Coordination of existing/future right-of-way needs

Coordination with other non-highway transportation facilities

Incentive/disincentive clauses

Innovative construction techniques/materials

The various TTC Strategies listed above are not intended to be all inclusive, but rather provide a range of possible strategies which might be considered by those persons developing the TMP. Use the space below (and/or attach additional pages) to highlight noteworthy strategies OR strategies which are not routinely used on this type of project.

Notes for Selection of TO Strategies:

Public Information Strategies

The Public Information component of the Transportation Management Plan (TMP) is coordinated by the Department’s Communications Office. The Department employs a wide range of standard public information related strategies on all relevant projects. These include, but are not limited to, the 511 Travel Information System, the Dynamic ITS Message Boards, and the TDOT Internet Site.

In addition, lane-closure meetings are held weekly where additional public information strategies are considered and initiated when warranted.

All work zone projects will follow the guidelines set forth in TDOT’s Public Involvement Plan. The various strategies described below are intended for use in developing the final TMP and are provided here for review and consideration.

Brochures and mail-outs

Press releases/media alerts

Paid advertisements

Public information center

Telephone hotline
