Transportation Planning Analysis Unit (TPAU)


 The Transportation Planning Analysis Unit provides technical services and support for long-range planning. Services provided fall into three distinct categories:

  • Analysis expertise for studies such as Transportation System Plans, corridor plans, refinement plans, management plans, project development, environmental studies; education and training in application of analysis procedures and tool use for ODOT staff, other government agencies and consultants.
  • Technical expertise in field of performance measures and system evaluation methods for multiple modes and various geographic scales. Work in this area includes the development and application of the statewide transportation greenhouse gas emissions model (GreenSTEP) and analysis of roadway performance for an urban area using a combination of travel demand models and mesoscopic traffic models.
  • Technical expertise and services in field of transportation modeling:
    • Urban travel demand model development and application for long range planning activity, working in close cooperation with MPOs and local jurisdictions on air quality conformity, system plans, and refinement plans,
    • Regional travel demand models, such as the Deschutes County Travel Demand model,
    • Statewide models such as the Statewide Integrated Model (SWIM) used for policy analysis to evaluate policy options in a dynamic representation of the interaction between land use, the economy and the transportation system; and the Highway Economic Efficiency Requirements System (HERS) used for the Oregon Congestion Management System.
