Chapter 1: Introduction
1.0 Purpose
The Project-Level Transportation Management Plan (TMP) guidance document outlines the
development, content, and purpose of the Project-Level TMP.
A Transportation Management Plan is a documented set of coordinated transportation
management strategies used to manage the temporary work zone impacts of construction
projects.
The purpose of the transportation management program is to minimize disruptions to public
traffic, including motorists, bicyclists, and pedestrians, the freight industry and communities
without compromising public or worker safety, or the quality of work being performed. A
Project-Level TMP, used for either single projects or coordination of multiple projects within a
given area, will provide the details behind the development of the Traffic Control Plan (TCP),
including the Temporary Pedestrian Accessible Route Plan (TPARP), and other measures that
will be put in place for each project or group of projects to achieve this goal.
The Oregon Department of Transportation (ODOT) has developed the Oregon Highway Plan
and Oregon Transportation Plan; these plans are considered Program-Level TMP’s. Corridor-
Level TMPs have also been developed for significant corridors throughout Oregon. Both the
Program-Level and Corridor-Level TMP’s help outline the development of requirements and
performance specifications for Project-Level TMPs. The goal of the project-level TMPs will be to
address the traffic related impacts of the construction projects in a cost-effective and timely
manner with minimal interference to the traveling public through the effective application of
traditional and innovative traffic mitigation strategies. TMPs use multi-faceted and multi-
jurisdictional programs of operational, communications, and demand management strategies to
maintain acceptable levels of traffic flow during periods of construction activities.
Mission
ODOT’s mission is to provide a safe, efficient transportation system that supports economic
opportunity and livable communities.
Goal
Our work zone safety goal is zero fatalities and injuries, including ODOT employees,
contractors, public safety professionals and the traveling public while efficiently moving people
and goods.
Guiding Principle
The best work zone design and management plan will maintain safety and mobility, a balance
that shall be analyzed continuously throughout the lifecycle of the facility.
Directive/Strategy
To accomplish this goal, project design teams shall consider the full range of options including,
but not limited to, separation of the traveling public from workers and work areas, speed
reductions, law enforcement, enhanced traffic control devices and signage, and overall roadway
and work zone design.
Effective communication with travelers is essential to establish reasonable expectations and
minimize unsafe driver behavior. While there is no single solution that is appropriate for all
roadway designs and work zones, whenever practicable workers should be separated from
traffic.
Resources
Mobility Committee
ODOT’s Mobility Committee is a resource that can provide necessary balanced guidance. Work
through your mobility coordinator and the mobility committee to reach resolution. Bring issues
forward early in the scoping and design stage to avoid surprises and keep everyone in the
problem solving mode.
Background
In September 2004, the Federal Highway Administration (FHWA) published updates to the
work zone regulations at 23 CFR 630 Subpart J. The updated Rule is referred to as the Work
Zone Safety and Mobility Rule (Rule) and applies to all State and local governments that receive
Federal-aid highway funding. Transportation agencies are required to comply with the
provisions of the Rule by October 12, 2007. The changes made to the regulations broaden the
former Rule to better address the work zone issues of today and the future.
Growing congestion on many roads, and an increasing need to perform rehabilitation and
reconstruction work on existing roads already carrying traffic, are some of the issues that have
led to additional, more complex challenges to maintaining work zone safety and mobility. To
help address these issues, the Rule provides a decision-making framework that facilitates
comprehensive consideration of the broader safety and mobility impacts of work zones across
project development stages, and the adoption of additional strategies that help manage these
impacts during project implementation. At the heart of the Rule is a requirement for agencies to
develop an agency-level work zone safety and mobility policy. The policy is intended to
support systematic consideration and management of work zone impacts across all stages of
project development. Based on the policy, agencies will develop standard processes and
procedures to support implementation of the policy. These processes and procedures shall
include the use of work zone safety and operational data, work zone training, and work zone
process reviews. Agencies are also encouraged to develop procedures for work zone impacts

1.2.4 Construction
The TMP and Work Zone Decision Tree are to be submitted to eBids for prospective bidders to
understand the safety and mobility expectations for the project. Construction staff should
By granted authority, ODOT has developed an additional criterion for identifying “significant”
projects:
All projects with a construction budget greater than $5 million.
As a “significant” project, the TMP must include all of the following:
A temporary Traffic Control Plan
Transportation Operation (TO) strategies – Efforts to minimize or mitigate traffic
congestion, delay, volumes, peak hour surges, etc., during construction
Public Information (PI) campaigns – Communication strategies designed to notify
and inform the affected stakeholders and the traveling public of project schedules,
changes, alternate routes and mobility options.
FHWA has recommended that a Traffic Control Narrative be prepared for all projects along
with the Traffic Control Plans. In order to meet the Work Zone Guiding Principle, ODOT now
requires that a Work Zone Decision Tree and TMP be prepared for all highway projects. The
TMP, at a minimum, will include a basic narrative of the project and discussion of the safety
strategies evaluated.
For projects that do not meet the specific definition of a “significant” project, the FHWA
recommends that transportation agencies consider including both TO and PI strategies in their
TMPs, when practical.
TMP development and an initial Work Zone Decision Tree will begin as early as the Project
Scoping phase. Because these are living documents, they will continue to grow and evolve
throughout the life of the project design phase. Upon completion of the design – during the
2.2.1 Introduction/Summary
The introduction/summary should include a brief overview of the project, including a brief
overview of the existing conditions and proposed improvements, recommendations for traffic
control for the project, and goals and objectives of the TMP. The introduction/summary may
also include table of contents, other organizational information, or TMP Roles and
Responsibilities. The introduction/summary should also include pertinent project specific
information that may have a large impact on the project, i.e. extremely high traffic volumes,
closures, etc.
Public Information
Discuss the public awareness and motorist information strategies utilized by the contract. The
information programs inform the public of the overall purpose of the project so as to generate
and maintain public support. The program also encourages changes in driver behavior during
the project to help minimize congestion by recommending alternate routes during construction.
Traffic Operation
The traffic operation section should discuss any traffic operations employed by the project to
lessen traffic impacts of the project. Items may include demand, work zone safety,
traffic/incident, or enforcement management strategies.
Project Description: Provide the location, purpose, and general scope of work for
the project.
Estimated Duration and Anticipated Dates: Provide the best available
information for the timeline for the project. This information is critical to Motor Carrier
for managing restrictions and stakeholder coordination and is needed as early in the
process as possible.
Traffic and Delay Analysis: Provide key details regarding current roadway
operation, including volume, truck volume, or presence of significant crash history. The
appropriate analysis methodology and output will vary by project type. At a minimum,
delay analysis should identify whether construction will result in a decrease of traffic
performance. The analysis should also include a sensitivity analysis by increasing
anticipated traffic volumes by 5%-10% to identify projects that have higher risk of
experiencing a major delay event.
Mobility Impacts: Motor Carrier requires that each project provide details regarding
impacts and restrictions to freight mobility, include information in the TMP required by
PD-16 and relevant to the Motor Carrier division and the mobility of the project.
Project Coordination: For projects on an identified critical route pairing per the
Mobility Procedures Manual, the design team must include actions taken by the Region
Mobility Liaison in the TMP. For all projects, provide information about any projects,
including local agency or permit work, and actions taken to coordinate so that impacts
are minimized.
Discussion of Traffic Management Strategies/Work Zone Decision Tree
Narrative: Provide detailed explanation for the selection of traffic management,
temporary traffic control devices, and the traffic control plan strategies. The purpose of
this section is to provide information for how and why the traffic control plan was
developed and to support stakeholders and construction offices in delivering the plans
as intended.
Traffic Data: Data related to the movement of vehicles, pedestrians, bikes, etc. on a
highway. Typical traffic data examples are: Average daily traffic (ADT) volume and
peak-hour volume, hourly traffic volumes, vehicle classifications, accident data, etc.
Roadway information (roadway types, conditions, capacity, etc.):
Information related to the roadway prism and network. Roadway classification, Terrain,
Speed Limits, design speeds, design vehicle, horizontal and vertical alignment, super-
elevation, grade, slopes(cut/fills), pavement type, clear zone, barriers, lane and shoulder
widths are typical roadway characteristics.
Land use (location of residences, businesses, industry, etc.): How the
land adjacent to the project is being used and how that impacts the project. Typically
used for economic impact analysis, stakeholders identification, management strategies,
and the TCP. May include Right of Way constraints and road approaches.
Existing Size Restrictions: Width, height, weight, or other highway restrictions
that limit vehicles travelling on a highway. Identify any existing height, width, or weight
restrictions that are present on the highway as well as routes that may be used as
marked or for emergency detours.
Environmental, Geotechnical, and Hydraulic issues: Project site conditions
that may impact project temporary traffic control. Environmental, geotechnical and
hydraulic issues may impact construction schedules, staging, etc. (in-water work
windows, etc.).
Transit service within area (type, frequency, etc.): Public transportation
facilities located or serviced within the work zone. Typically these services have to be
maintained during the project.
Project location/limits/length: Physical limits of the project and temporary
traffic control.
Location of other construction projects: Other projects near the work zone that
may impact the temporary traffic control. Typically used to determine conflicting
projects and overall delays.
Special events: Local or regional events that may impact the temporary traffic
control. Used to determine if the proposed construction schedule may need to be altered
to accommodate local events. This information should be gathered through
coordination with local officials and/or chambers of commerce, as well as through
coordination with ODOT Region staff. Examples include bike rides, football games,
parades, etc.
Utilities: Public utilities (gas, power, water, sewer, etc.) that travel through or are in
the vicinity of the project. Utility conflicts may impact construction schedules, staging,
etc.
ADA/Pedestrian accommodations: Existing ADA/pedestrian facilities located
within the work zone. ADA/pedestrian accommodation should be maintained during
the project.
Mobility Requirements: Specific Mobility requirements and standards requiring a
minimum roadway prism and a maximum amount of delay. See ODOT Mobility
Procedures Manual.
Structures, including bridges, retaining wall, sound walls, sign bridges:
Structures within the vicinity of the work zone that impact the traffic control plan.
Structures usually confine the roadway prism.
Signs, Signals, & Illumination: Traffic features located within the roadway prism.
Project may be able to use the feature, provide temporary features, or have to
cover/remove features during the project.
Railroad, Rest Areas, Transit, Bus, Weigh Stations, Parks, Stadiums,
Schools, etc.: differing types of adjacent facilities may have broad impacts to the
project.
Funding: The origin of the funds and the amount of funds may impact the level of
traffic control that can be supported for the project. Safety should not be sacrificed
because of budget constraints.
Right of Way: Land owned and occupied by a public entity where a public road
exists. Width of right of way may impact TTC strategies.
Emergency Services/School Bus Routes: Services that are maintained through
the work zone. Depending on whether or not these services are disrupted the TTC
strategy may need to accommodate these services.
Seasonal restrictions: (traffic variations, weather-related work windows, etc.)
Restrictions that only occur during a certain time of year. May impact the TTC strategy.
Radio: Radio dedicated to providing information about the project to certain users.
Traffic reports, dedicated Highway Advisory Radio, radio targeting certain groups, i.e.
Trucks, etc.
Variable Message Signs: Portable or permanent message signs that are able to
relay information to road users. Various types of information can be included on VMS,
including warning messages, travel times, incidents, etc.
511 / Tripcheck: Web or phone based traveler information systems that can provide
road users valuable information about a work zone.
4.1.1 Possible/Viable
The first step in the evaluation process for an available traffic control strategy is to consider if
the basic concept fits within the boundaries of the project’s purpose. Strategies that are more
effective at providing positive separation of workers from live traffic should receive the highest
scrutiny and consideration. Notes regarding the possibility or viability of a strategy can be
minimal, provided the record indicates that the strategy was actively considered. It is
reasonable that certain options are obviously inappropriate given the project scope.
4.1.2 Impacts
This section asks the user of the form to consider the potential costs and tradeoffs for each
strategy. These impacts could include monetary expense, lane-width reductions, lengthening
the construction schedule, potential safety risks to other road users, etc. The listed impacts
should include the key details that drive the ultimate decision on whether or not to include the
strategy in the design. The designer should make every attempt to include these impacts from
an objective point of view; the decision will be made later.
Total Closures: Totally closing the facility to perform work. Traffic is usually
diverted around the project via an official detour or alternate routes. Total closures
usually allow the project to be completed in a shorter timeframe.
Lane Shifts: Maintaining lanes through a project but using available surfacing to shift
traffic over a certain distance to move traffic around a work area.
Construction Staging/Phasing: Breaking the project into manageable pieces to
be able to construct the project while maintaining traffic. The project is usually broken
down into stages, which are further broken down into phases. Different stages/phases
will use different configurations of alignments and traffic control devices.
Mobility Restrictions: Restricting oversize load access through the project to
minimize the roadway prism during construction.
Reduced Speed Limits: Reducing the speed limit through the project with the aims
of increasing safety for both traffic traveling through the project and workers. Reducing
the speed limit by a large amount may be counterproductive as large speed variances
may decrease safety.
Enforcement Program: using police to either enforce the work zone or provide a
presence in the work zone, aim is to safety maintain traffic through the work zone and
increase worker safety. Usually used when workers are exposed to traffic in an adjacent
lane. Currently ODOT’s work zone enforcement grants administered through the Work
Zone Safety program are the method to get enforcement on a project.
One-lane, Two-way Operation: using flaggers, pilot cars, or temporary signals to
move traffic through a one lane section of roadway while the other lane is closed.
Construction work can be performed in the closed lane.
Rolling Slowdown: using construction vehicles to slow traffic to allow a large gap in
the traffic stream (up to 20 minutes) to perform short duration construction work.
Lane Closure Restrictions: Restricting the time frames when lane closures can
occur to limit the impact to traffic travelling through the project. Usually this is
completed by a traffic analysis that is scaled to the size and location of the project.
Detours/Alternate Routes: Detours and alternate routes are used to divert traffic
around a project. A detour is a dedicated route where traffic that would normally go
through the project is diverted; the traffic will then be brought back onto the normal
route at the end of the detour. An alternate route is a dedicated route that traffic is
encouraged to use to bypass the project.
Traffic Operations Center: A project specific Traffic Operations Center to manage
traffic through a project. On mega-projects a Traffic Operations Center specific to the
project may be worth the expense to provide real time traffic monitoring.
Traffic Control Supervisor: Dedicated trained traffic control personnel on the
project to monitor and adjust the temporary traffic control.
