TMPs and the WZ Rule

Requires development and implementationof TMPs for all Federal Aid highway projects

Required content depends on significance

Must always include a Temporary TrafficControl (TTC) Plan

For significant projects, TMPs must also have:

Traffic operations (TO) component

Public information and outreach (PI) component

In brief, a significant project is one

that the agency expects will cause

a relatively high level of disruption.

What is a TMP?

Set of coordinated

strategies implemented to

manage the WZ impacts of

a project

Scale-able projects with

more expected impacts

may need more analysisand more strategies

Transportation Management Plan


8/30

What is a TMP?

DOTs create design documents to showhow they are going to build a project

The TMP shows how the DOT is going to

manage transportation needs during aproject

With todays WZ challenges, a TTC plan

may not be enough

TMPs = a more comprehensive approach

to managing WZ safety and mobility

Why TMPs?

WZ management is increasingly complex Increasing traffic volumes using the same roadsthat agencies need to maintain and rehabilitate

Requires traffic management efforts beyond TTCplans

Key issues: Safety

Mobility

Constructability

Objective:Achieveconstructability withoutcompromising safety and

mobility


12/30

Why TMPs? Key BenefitsAddress safety and mobility impacts of work zones at

corridor and network levelsPromote efficient and effective construction phasing andstaging, minimize contract duration, and control costs

Improve safety for workers and road users

Minimize the traffic and mobility impacts of a work zoneMinimize circulation, access, and mobility impacts tolocal communities and businesses

Improve public awareness

Minimize complaints from road users, businesses, andcommunities

Improve intra- and inter-agency coordination


13/30

TMPs are a Tool

Part of overall WZ management

Effective WZ management requires:

Understanding the likely impacts of a WZ

Safety and Mobility ImpactsA combination of strategies

Strategies should be chosen to solve

specific problemsTMPs = more comprehensive approach

to managing WZ impacts


14/30

When is a TMP Developed?

TMP development should begin during systemsplanning and progress through design

Conducting TMP analyses early in projectdevelopment helps ensure:

Systems planning and preliminary engineering:TMPdevelopment and implementation costs included in theproject budget

Design:Agencies consider WZ impacts in evaluation andselection of design alternatives For some projects it maybe possible to choose a design alternative that alleviatesmany WZ impacts

Final TMP development occurs during DESIGN


15/30

During Design

Final assessment of WZ impacts is done,

which should affect the choice of:

Best construction/staging option(s)

Most suitable design and contracting

approach

Most appropriate WZ traffic management

strategies


16/30

TMP Strategies to Manage

WZ Impacts

Designers are encouraged to consider these strategiesearly on in the process for all projects, even if they arentincluded in the TMP

Temporary Traffic

Control (TTC)

Strategies

Public Information

(PI) Strategies

Transportation Operations

(TO) Strategies

-Traffic control/design

approaches-Traffic control devices

-Project coordination,

contracting, and

innovative construction

-Public awareness

-Motoristinformation

-Demand management

-Corridor/networkmanagement

-WZ safety management

-Traffic/incident

management & enforcement


17/30

Identification of TMP Strategies

Should be based on:

type of work zone

traffic conditions anticipated WZ impacts

project constraints

construction phasing/staging plan conditions in surrounding area (e.g.,

alternate routes and modes)


18/30

Some Considerations

Agency WZ policies

E.g., Maximum WZ queue lengths/delays

allowed

Lane Closure policies/charts that specifywhen a lane closure is permitted

Analytical/modeling tools used by the

agency


19/30

Some Considerations (cont.)

Concerns ofstakeholders

disciplinaryapproach

TMP


20/30

TMPs Need to Be

Well-thought outStarted early in project development

Coordinated with other projects nearby

Contain a combination of strategiesFit the expected level of WZ impacts

Funded

Updated as needed after project awardImplemented!

Monitored and adjusted as needed


21/30

Tips for Developing TMPsEstimate and budget for TMP development and

implementation early in project development (updateas appropriate throughout project) Include funding for monitoring traffic conditions during construction

to track TMP effectiveness - can help for future WZs

Consider and address WZ impacts from a broadtransportation management perspective (rather thansolely a traffic control perspective) Balance constructability and staging requirements with WZ

management strategies

Coordinate phasing/staging with other strategies in TMP (TTC, TO,

and PI plans)

Coordinate with key parties to jointly identify WZimpacts issues to account for and managementstrategies to address them


22/30

Tips for Developing TMPs (cont.)Use strategies that keep lanes open, especially during

peak traffic times E.g., narrowing lanes or using shoulders to maintain # of lanes; contractincentives/disincentives; lane rental; damages for late lane opening; nightwork

Use "Triggers" - e.g. when 75% of max delay is approached, lane(s) areopened to accommodate traffic

Consider using extended closures or full closures versusnumerous night closures

Use strategies that facilitate decision-making by the publicto avoid the WZ (e.g., public awareness, advance signage inlocations prior to key motorist decision points) these tend to behighly effective

Update the TMP, as needed, throughout projectdevelopment and implementation

Training is important for all divisions involved in TMPs

Management support is needed for effective TMP efforts


23/30

Use of TMP StrategiesThe agency is

expanding WZmanagement

beyond traffic

safety and control

to address

mobility throughthe consideration

and use of

transportation

operations (TO)and public

information (PI)

strategies.

Critical Issues in

TMP Development


25/30

Responsible Persons

Both the DOT and the contractor arerequired to designate a responsible

person:

At the project-level Who is appropriately trained

Who has primary responsibility and

sufficient authority for implementing the

TMP and other safety and mobility aspects

of the project


26/30

TMP Formats

TMPs need to be documented

Options include:

Single document with all included material

Brief document with summaries of analysis

results and decisions, where the fulldocumentation is in the project files or similar

Powerpoint format has been used

Others?

Scope, content, level of detail may varybased on DOT policy and impacts


27/30

TMPs and the PS&Es

PS&Es shall either contain:All the applicable elements of a DOT-developed TMP, or

Provisions for a contractor to develop a

TMP (e.g., for design-build jobs)

DOT must approve contractor-

developed TMPs

DOT must approve contractor-proposedTMP changes


28/30

TMP-related Review Items

Work with your Division Area Engineers toensure appropriate TMPs are developed,

and relevant parts included in bid packages

Was a TMP developed for the project?

Does the TMP consider the expected

impacts of the project?

Has the agency determined what type ofproject?

Were key stakeholders involved?


29/30

TMP-related Review Items (cont.)

Does the TMP contain strategies tomanage the identified impacts?

Are the strategies reasonable for the levelof expected impacts?

Is implementation of the TMP funded?

Has a responsible person beendesignated for the DOT?

Has the DOT approved the TMP per itspolicies/procedures?
