Oahu Regional Transportation Plan (ORTP)

What is the ORTP?

ortp coverThe Oahu Regional Transportation Plan (ORTP) is a long-term vision document that outlines transportation goals, objectives, policies, and projects for Oahu. Projects that appear in the ORTP are eligible for Federal transportation funding assistance.  The 20-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 economic 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 Oahu’s residents and visitors. The ORTP is updated every five years.

ORTP 2040

The objective of this Oahu Regional Transportation Plan (ORTP) 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 increasing 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.
