Oregon Modeling Improvement Program

Oregon Modeling Improvement Program (OMIP)

State highway departments historically responded to the broad public view that roads are fundamental to a mobile, accessible and prosperous America. Beginning in the 1970s, several mandates dealing with how projects are selected and designed resulted from public concerns about the environmental and social impacts of road construction. Generally, they require an open public process, agency coordination, and alternative solutions. The mandates prescribed the process of considering how transportation infrastructure investments are decided and designed, and specified measures to ensure compliance and coordination.

To address these mandates, changing how to think about providing transportation services is important. Recognizing that land use, economic and transportation decisions and investments are related and interdependent is a big step towards addressing the intent of the mandates. The historic mathematical models used by engineers and planners are inadequate to analyze and predict the multi-dimensional environment of today. New methods that analyze travel behavior, location preferences, market forces, transportation infrastructure, and policies and how they interact with one another are needed.

The Oregon Department of Transportation (ODOT) embarked upon a comprehensive Oregon Modeling Improvement Program (OMIP) in 1994. OMIP was developed to consider how to meet the new rules and regulations. It includes three primary areas of focus:

  • Bringing together stakeholders and providing forums for information exchange and development of new ideas,
  • Obtaining new and expanded modeling tools necessary to provide information for efficient and effective-decision making. These tools need to address the complex and dynamic interactions among the economy, land use and transportation. Information coming from analysis must be presented in a form easily understood by a wide variety of users.
  • Providing formal education, outreach and training on the need for and use of these tools as an ongoing program activity.

The Oregon program developed using a five-track approach intended to make the modeling program useful and accessible to decision-makers, stakeholders, and practitioners. The five OMIP tracks include: resources, outreach, development, implementation, and data.
