Statewide Traffic Mobility

Mobility Information

The Oregon Department of Transportation’s most essential function is to provide safe mobility for people and goods. Mobility can be defined as the ease with which people and goods move throughout their community, state and the world.
 

​ODOT staff collaborate and communicate with key stakeholders to create plans and designs that are in harmony with highway user demands while maintaining mobility and safety. By sharing upcoming construction project information and maintenance work with the stakeholders, we can forecast potential conflicts and resolve issues together.

Our key stakeholders include members from:
  • Oregon Trucking Association
  • Association of General Contractors
  • Oregon Mobile Home Association
  • AAA
  • Freight haulers from the heavy haul industry
Addressing mobility early in the planning process for both construction and maintenance work helps to:
  • Maintain and enhance work zone safety.
  • Minimize delays for both the traveling public and freight industry.
  • Minimize detouring trucks on local roads through communities.
  • Minimize size and weight restrictions to the freight industry.
  • Maintain alternate routes for freight movement when a route needs to be restricted or provide windows of opportunity for freight to move through.

​The Mobility Procedures Manual is a guide to how Oregon coordinates construction and maintenance activity while still keeping traffic and freight moving. It is a comprehensive outline of the approach that ODOT and its construction partners take when planning and executing all road and bridge projects.

It sets project standards and minimum requirements regarding:
  • Communication and coordination.
  • Vertical and horizontal clearance.
  • Bridge weight restrictions.
  • Delays.
  • Detours.
  • Staging.
  • Design.

​Oregon law prohibits permanent reductions in vehicle carrying capacity on an identified freight route based on ORS 366.215 — Reduction of Vehicle Carrying Capacity.

Exceptions are allowed if safety or access considerations require the reduction. An exception may be granted by the Oregon Transportation Commission if it is in the best interest of the state and freight movement is not unreasonably impeded.
 
Examples of features that may reduce the vehicle carrying capacity of a highway are:
  • Raised pedestrian islands.
  • Bulb-outs.
  • New sign or signal structures over the roadway.
  • Raised medians/curbs and traffic separators.

​To ensure adequate vertical clearance on the state highway system for tall loads like transformers, minimum Vertical Clearance Standards were established for all new construction.

Consultation with MCTD is required for:

  • Any construction that proposes less vertical clearance or that decreases existing vertical clearance.
  • Any new structure being proposed over the highway where none existed before, such as new sign and signal structures.

​Appropriate communication and analysis must happen before implementing a proposed weight restriction on the state highway system.

​Every time a roundabout is proposed to be installed on the state highway system, the Highway Directive — Roundabouts on State Highway System must be followed. This directive establishes the expectations and processes concerning freight mobility.

Project Requirements and Guidance

The Highway Mobility Operational Notice — PD16 provides guidance on implementing key ODOT mobility policies, processes, roles and responsibilities related to project delivery. This guidance applies to all state and federally funded projects on state highways, at the project development stage through construction. This operational notice is consistent with the policies and procedures contained within the more detailed ODOT’s Mobility Procedures Manual, the accepted authority for mobility policy for the Agency.

Key Policy considerations include:

  • Identification of Mobility Issues.
  • Communication and Coordination.
  • Temporary Restrictions.
  • Permanent Restrictions.
  • Transportation Management Plan.
  • Contract and Design Considerations.

The Project Mobility Consideration Checklist document is a tool to help identify potential impacts to freight and traffic mobility in the development phase of a project.

  • During planning and design phases of a project, the project team must provide for stakeholder and ODOT Mobility Advisory Committee input. MCTD will help facilitate conversations through email or meetings.
  • The Motor Carrier Transportation Division requires at least 15 business days to review mobility consideration checklists for projects that have already been shared.
  • If the project has not been shared with stakeholders prior to checklist submission, more time may be required.
  • A TMP and Decision Tree must be submitted with the checklist.
  • Any potential ORS 366.215 impacts must be shared and approved before signing the checklist. More time is needed for review and additional information is required. See Guidance for Implementation of ORS 366.215.
  • Off-system projects that create a mobility impact on the state system must also comply with PD-16 and this checklist.
  • Prior to PS&E, MCTD must sign all mobility consideration checklists for highway projects that impact freight and traffic mobility. Project Leaders and Local Agency Liaisons with projects, both on-system and off-system that have no mobility impacts, should check the “no mobility impacts” box and sign the checklist.
  • MCTD signature is not required for a “no mobility impact” project before submitting it with the PS&E package.
  • The TMP should contain all information needed to sign the Mobility Considerations Checklist.


Changes to project Mobility Consideration Checklist

Before making changes during construction that have the potential to adversely affect mobility or run counter to previous agreements, the Project Manager:

  • Must discuss proposed changes with the contractor, Region Mobility Liaison and any relevant region resources to discuss proposed changes to determine if the change is warranted and supported by the region.
  • Engage MCTD to discuss and get agreement with the potential changes before any agreements are made with the contractor, if supported by the region.
  • Document MCTD and trucking industry support of any potential new restrictions and provide a copy of the documentation to the Region Mobility Liaison.


Leadership Direction for Changes to Mobility Consideration Checklist

​A TMP is a documented set of coordinated transportation management strategies used to manage the temporary work zone impacts of construction projects. For TMP examples, go to the Traffic Standards website.

Purpose
  • Minimize disruptions to motorists, the freight industry and communities.
  • Maintain public and worker safety without compromising the quality of work being performed.
  • Address growing congestion on many roads and an increasing need to perform rehabilitation and reconstruction work.
  • Provide guidance to ODOT designers on how to develop project level TMP documents for projects. The project level TMP guidance document has been adopted by ODOT and applies to all projects in conjunction with the goals of the FHWA rule on Work Zone Safety and Mobility 23 CFR 630 Subpart J.

Other Mobility Related Information to Included

  • Critical route pair information.
  • Detour route information. If on a local road, list the following:
    - Who approved it?
    - Describe truck modeling.
    - Will the detour route allow oversize loads that are currently allowed on the restricted route?
    - Are there any restrictions on the detour route?
  • Can oversize loads be accommodated through the work zone by moving barriers and equipment out of the way and waving loads through with a short delay?
  • Is advanced noticed required?
  • Are crossovers used? If so, will traffic travel under structures?
  • When lane closures are used, describe how much width is available for traffic between barriers.
  • Is the work zone on a tangent or curve?
  • Describe any ramp closures.
    - Which on and off ramps are closed?
    - How long will the closure last?
  • Specify hours of operation for the project.
    - Is the work done at nighttime, daytime or both?
    - Is weekend work allowed?
    - Are there windows of opportunity for loads to get through?
The new work zone safety directive requires the following documents in the project delivery process.
  • The TMP is now required for ALL projects.
  • Work zone decision tree.
 
Background
  • On December 2015 at a Work Zone Executive Strategy Sessions Committee Director Garrett and Paul Mather agreed to implement the Work Zone Guiding Principle into the culture of ODOT.
  • In 2016, Bob Pappe and the TCP Unit led the charge of developing a process, templates and guidance. While developing this framework for implementation, the project team met with over 30 Leadership Teams/Stakeholder groups to both communicate this direction and to better understand customer and user requirements.
 

​Purpose
To consider planning/design options for all STIP projects on ODOT facilities and local agency projects on the state highway system that include:

  • Construction staging.
  • Traffic control.
  • Separation strategies.
  • Public/stakeholder involvement.
  • Communications that occur throughout the entire project lifecycle.


Requirements

The Wor​k Zone Decision Tree will become part of the Transportation Management Plan and document:

  • Work zone safety options.
  • The impacts of those options.
  • Recommendations and decisions made.

Highway Restriction Notice

Whenever construction or maintenance work will close a state highway or ramp; or restrict the width, length, height or weight of trucks within a work zone on a state highway or ramp, a Highway Restriction Notice Form must be completed online and submitted to the Motor Carrier Transportation Division prior to the restriction beginning.
 

Submitting Highway Restriction Notices allows MCTD to ensure work zone safety and help motor carriers hauling oversize loads plan their trips by:

​No restriction is needed if ALL of the following conditions are met:

  • Project/maintenance staff can safely accommodate all unannounced oversize loads through the work zone with minimal delay by moving cones, equipment out of the way as described in Activity 1 of ODOT’s Maintenance Mobility Requirements. Contact MCTD Mobility for accommodating requirements on mainline interstate highways.
  • The minimum width maintained for a single​ open travel lane is 22 feet or greater between barriers, including the travel lane plus any paved shoulder.
  • The minimum width maintained for traffic is 28 feet or greater for two travel lanes for one way traffic.
  • The minimum width maintained for traffic is 28 feet or greater for two travel lanes for two-way traffic with no traffic separator/candlesticks being used on the centerline.
  • No lane shifts or lane closures will divert traffic into a travel lane with less vertical clearance underneath structures.
  • Traffic is not detoured onto a secondary route.
  • Ramps are not closed.
  • No length restriction is needed.
  • No weight restriction is needed.
Notes
  • Overheight loads are instructed to drive in specific travel lanes with greater vertical clearance.
  • Oversize loads are not allowed to use detours unless it is specifically listed on the permit.
  • The route must be reviewed and approved for the specific dimensions allowed on the permit.
Exception: If all of the above conditions are met but contract language states a highway restriction notice must be submitted, consult with the ODOT project manager to see if one is needed.

Regardless of the type of restriction, contractors are required to submit the Highway Restriction Notice Form 35 days before work begins to allow time for the ODOT project manager to review and submit the form to MCTD.

  • MCTD must receive restriction notices 14-28 days prior to work beginning.
  • The amount of notice needed is based on the location and type of restriction.

See chapter five of our Mobility Procedures Manual for specific notification requirements. Typical requirements are:

  • 14-day notice — Ramp closures to/from a local road.
  • 28-day notice — Full highway closures and traffic is being detoured.
  • 14-28 day notice — Width restrictions due to lane closures or reduced roadway width. See Daytime and Nighttime Width Restrictions.
  • 28-day notice — Ramp closures to/from a state highway.
  • 28-day notice — Weight restrictions affecting annual oversize permit holders.
  • 28-day notice — Length restrictions affecting annual oversize permit holders.

The amount of notice needed is based on the route, the width and whether the restriction is during the day or night.

  1. Use the following Freight Mobility Maps to determine the color of route the restriction will be on.
  2. Use the tables below to determine the amount of notice required.
  3. Use the Sunrise/Sunset Calendar to determine if the allowable lane closure hours and/or width restrictions occur during the daytime or nighttime requirements.

Daytime width restrictions occur from ½ hour before sunrise to ½ hour after sunset.

ODOT rolled out its first Highway Mobility Operations Training for staff in 2005. Since then, dozens of eight-hour sessions were held for hundreds of ODOT employees at all levels of the organization such as planners, project managers and maintenance staff. As a follow up opportunity, ODOT employees were invited to four-hour mobility training sessions tailored to particular staff.
