Oahu Regional Transportation Plan (ORTP)


What is the ORTP?

The Oʻahu Regional Transportation Plan (ORTP) is a long-term document that outlines transportation goals, objectives, policies, and projects for Oʻahu. Projects that are in the ORTP are eligible for Federal transportation funding. The 25-year horizon of the plan incorporates forecasted population, housing, employment, environmental, land-use, and technology changes. Based upon projected transportation needs, financial resources, and community input, the ORTP identifies strategies and actions to promote the development of an integrated, inter-modal, surface transportation system that facilitates the safe, efficient, and economical movement of people and goods. It also identifies specific highway, transit, freight, bicycle, and pedestrian projects that are designed to improve safety, mitigate congestion, and increase mobility for Oʻahu’s residents and visitors.

The ORTP is updated every five years, and the current plan is the ORTP 2045.

Please refer to the Transportation Improvement Program (TIP) for the current list of short-range projects and programs.

2045 ORTP: Ke Ala Imua, The Path Forward for Oʻahu

The 2045 ORTP update process was completed in April 2021.  The ORTP 2045’s theme is Ke Ala Imua, which roughly translates to The Path Forward.  The ORTP 2045 will lay out our path forward for our transportation system for the future.  Our future transportation system is one that will be multi-modal, equally supporting people who are walking, biking, using transit, and driving to get to their destination.

Our future transportation system will be safe, for all people and all modes of transportation.  Our future plan will take into consideration climate change, sea-level rise, flooding, the City and County of Honolulu’s energy goals, and citizen concerns, among other things.  How can we address Oʻahu’s challenges for our transportation future?

Early Input on the Land Management Consultation for Transportation Projects and Programs in the 2045 ORTP

In preparation for the update of the ORTP, the OahuMPO is seeking input from Federal, State, wildlife, and regulatory agencies on potential environmental mitigation activities for transportation projects and programs proposed in the 2045 ORTP.

OahuMPO is required by the Federal Highway Administration to include a discussion of the types of potential environmental mitigation activities and potential areas to carry out these activities, including activities that may have the greatest potential to restore and maintain the environmental functions affected by the projects and programs in the ORTP (23 CFR § 450.324).  The discussion may focus on policies, programs, strategies, or project level mitigation activities.

To assist with the consultation, OahuMPO mapped all proposed projects and programs in GIS, with environmentally sensitive areas, provided by the Department of Land and Natural Resources, Division of Forestry and Wildlife and the University of Hawaiʻi Sea Grant Program.  The map can be viewed here.

A list of projects and programs that would overlap with the layers above, as well as projects that overlap with historically significant areas (not publicly available on the map above), provided by the Department of Land and Natural Resources, State Historic Preservation Division can be found here.

A list of all projects and programs can be found here.

The final 2045 ORTP can be found here.

Please help us identify any concerns, policies, programs, strategies, and recommended environmental mitigation activities, for the proposed projects and programs in the 2045 ORTP, using this survey.

Responses are due on December 8, 2021 


Final Draft Plan Presentations and Policy Board Vote to Approve

The final draft plan was presented at the April 2021 Citizen Advisory Committee, Technical Advisory Committee, and Policy Board meetings. At their April 27, 2021 meeting, the OahuMPO Policy Board voted to approve the 2045 ORTP.

Public and Intergovernmental Review Period on the Draft 2045 Oʻahu Regional Transportation Plan 

The draft of the 2045 Oʻahu Regional Transportation Plan was out for public comment from March 1-29, 2021.  

The preliminary list of projects and programs shared through this webpage did not change in the draft plan, as it was determined by the transportation revenue forecast that there is enough projected transportation funding to cover the expected costs of proposed projects and programs. 

To view the comments and responses received during the intergovernmental and public review period, please click here.

Transportation Revenue Forecast  

OahuMPO and its consultant, Jacobs finalized OahuMPO’s Transportation Revenue Forecast, which forecasts the amount of money, that Oahu can reasonably expect to be available to spend on transportation projects and programs through 2045.  This forecast is important because it helps to guide which projects and programs are selected for funding.  In compliance with Federal law, the costs of projects and programs selected for funding must be within the forecasted revenue amount.   

A final draft of the revenue forecast was presented at the February Citizen Advisory Committee, Technical Advisory Committee, and Policy Board meetings.  Below is the February Policy Board presentation for reference:

2020 Congestion Management Process Report 

All MPOs with a population greater than 200,000 are required to have a Congestion Management Process (CMP), including OahuMPO.  The purpose of a CMP is to identify the process for collecting congestion related data, develop performance measures used to report congestion data to the public, and guide funding toward projects and strategies which most effectively address congestion.  The CMP was incorporated into our project and program prioritization process for the ORTP, to help inform project and program selection. 

An online dashboard (draft) of the CMP may be viewed here. 

A final draft of the 2020 CMP Report may be viewed here.

A final draft of the CMP Report was presented at the January Citizen Advisory Committee, Technical Advisory Committee, and Policy Board meetings.  Below is the January Policy Board presentation for reference:

Existing and Forecasted Conditions 

One of the requirements for MPO’s long-range transportation plans is an Existing and Forecasted Conditions Report.  Information included in the report ranges from socio-economic, commuting, and employment data, as well as information about our existing transportation system.  This information is used to inform the selection of projects and programs for the 2045 ORTP. 

An online dashboard (draft) of the Existing and Forecasted Conditions Report may be viewed here. 

A final draft of the Existing and Forecasted Conditions Report will be presented at the January Citizen Advisory Committee, Technical Advisory Committee, and Policy Board meetings.

Call for Projects and Programs

OahuMPO held it’s Call for Projects and Programs from August 12, 2020 – September 30, 2020, where it asked it’s partner agencies for projects and programs to consider including in the ORTP 2045.  Projects and programs expected to request funding in Federal Fiscal Years (FFYs) 2022-2025 will also be included in the FFYs 2022-2025 Transportation Improvement Program (TIP).  One requirement for transportation projects and programs to be eligible for Federal funds is that the project or program must be included in the ORTP and TIP.

OahuMPO, as the designated MPO for the island of Oʻahu, receives Federal transportation funding, and it has the discretion to distribute these funds to agencies to construct and/or implement projects and programs through the ORTP and TIP.

This Call for Projects and Programs is the first that will use the new scoring criteria and a revamped application. Both the criteria and assigned scores were written by taking into consideration feedback from the public and the number of points designated by the goal prioritization activity done in Phase 1 of public engagement, and feedback from our technical working group, Technical Advisory Committee, Citizen Advisory Committee, and Policy Board. The evaluation process scores projects and programs through a quantitative method to compare how projects and programs meet each of the ORTP goals and objectives.

Phase I of Public Involvement Completed

OahuMPO staff have created a final draft of the public participation phase 1 chapter of the ORTP 2045. In this chapter, we discuss the process along with an evaluation of the outcomes in efforts to build recommendations for going forward.

Upon evaluating our first round of public participation, we honed in on areas where we can improve for future phases of public involvement for the ORTP 2045 and future regional transportation plans. The areas in which we can improve include:

  • Rethinking engagement by focus groups
  • Engaging young and middle-aged populations
  • Translating materials to be more linguistically available
  • Collecting demographic data which better corresponds to state and national level data

ORTP 2040

The objective of this Oahu Regional Transportation Plan (ORTP 2040) is to guide the development of transportation on our island through the year 2040. It presents both a vision of an improved transportation system to serve the needs of Oahu’s population as well as specific projects that will achieve that vision.As the federally-designated Metropolitan Planning Organization, the OahuMPO develops the ORTP 2040 and identifies and prioritizes transportation projects and programs in the Transportation Improvement Program (TIP). The Policy Board is the decision-making body of the OahuMPO and approves the ORTP.The island of Oahu faces several major transportation challenges and opportunities. While most of Oahu’s existing development lies along the southern portion of the island, future population and job growth is expected to occur to the west side of the island and in the Central Oahu and Kakaako areas.  Without improvements, this growth will result in increased congestion and longer travel times along already congested roadways such as Interstate Route H-1.The vision statement in ORTP 2040 proposes that Oahu should be a place where we will have efficient, well-maintained, safe, secure, convenient, appropriate, and economical choices in getting from place to place. The regional goals and objectives in ORTP 2040 propose that our transportation system should move people and goods in a manner that supports the island’s high quality of life, natural beauty, economic vitality, and land use plans.Public input was obtained on ORTP 2040 in several phases, including a subcommittee of the Citizen Advisory Committee, public listening sessions held in each of Oahu’s eight planning districts, and an online survey. Overall, the results of the public outreach activities identified several themes that were consistent across all geographies. Traffic congestion, roadway maintenance, and safety were repeatedly identified as major concerns. There was also strong public support for continuing investments in public transit and for pedestrian and bicycle facilities.In response to this public input and the feedback from other agencies and stakeholders, the ORTP 2040 proposes a comprehensive package of more than $17 billion in transportation projects and programs, including:

  • Congestion Mitigation and Alternative Projects: ORTP 2040 includes projects that increase and enhance Oahu’s existing network of bicycle and pedestrian facilities. In addition, it identifies Travel Demand Management (TDM) and technological projects that improve traffic flow through Intelligent Transportation Systems (ITS);
  • Modernization Projects: Because transportation by automobile will continue to be the primary travel mode in the future, roadway capacity improvements (adding lanes, new or reconfigured interchanges) will be needed along Interstate Route H-1 corridor and in the developing areas of Oahu to handle future growth;
  • Transit Projects: The Honolulu High-Capacity Transit Corridor Project and other improvements in both transit service and facilities are key components of ORTP 2040; and
  • Operations, Maintenance, Preservation, and Safety: ORTP 2040 proposes a significant amount of funding to support the maintenance, preservation, and safety of the existing transportation system.

The projects and programs included in the ORTP 2040 reflect the desire to make Oahu’s transportation system more sustainable. The overwhelming share (85%) of plan expenditures is committed to support maintenance and operations and transit expansion while other funding is for system preservation, high technology projects such as ITS, and bicycle and pedestrian improvements. The remaining balance goes to modernization projects. The projects in ORTP 2040 are prioritized as either “Mid-Range Projects,” (proposed for implementation by the year 2029) or as “Long-Range Projects” (proposed for implementation by the year 2040). Projects were placed within each time period based on input from the implementing agencies (City and County of Honolulu’s Department of Transportation Services, Honolulu Authority for Rapid Transportation, and Hawaii Department of Transportation). Using the OahuMPO travel demand forecasting model, a series of analyses were conducted to evaluate the performance of the OTRP 2040 implementation in comparison to forecasted (year 2040) no-build conditions with only existing and committed transportation projects in place.  These technical analyses concluded that implementation of the ORTP projects will help reduce hours of delay and travel on an island-wide basis and will alleviate some congestion on roadways in the Ewa/Kapolei and Waianae Coast areas and in the Interstate Routes H-1/H-2 merge area.ORTP 2040 is a fiscally constrained plan that identifies the revenues to cover the estimated costs of the projects and programs proposed in the Plan. The costs presented in ORTP 2040 are planning-level cost estimates. Amounts for programs are expressed in Year-of-Expenditure (YOE) dollars and a two percent (2%) inflation rate is assumed for projects. A variety of Federal, State, and local revenue sources are expected to finance the more than $17 billion in proposed transportation improvements.ORTP 2040 will be implemented through updates to the OahuMPO TIP. Successful implementation of the ORTP will require the evaluation of the effectiveness of its proposed transportation projects and programs. ORTP 2040 identifies several potential evaluation methods: including the preparation of a data management and sharing study; the development of quantifiable criteria in the TIP; and survey research.The ORTP 2040 can be downloaded here.ORTP DevelopmentORTP-2
