  Citation × Citation Citation Abstract Copy Title: A Brief Portrait of Multimodal Transportation Planning in Oregon and the Path to Achieving It, 1890-1974 Author: Abbott, Carl, Lowry, Sam Year: 2010 This project was designed to outline transportation chapters of a planned written history of Oregon land use planning, written in ways that would make the transportation planning profession relevant to a popular audience. The writing would focus on stories from the profession, and on historical facts and events in Oregon transportation planning history that would surprise or enlighten popular reading audiences. Technology transfer would occur through publication of one or more written pieces of work. The result is a topical and historical tale entitled "A Brief Portrait of Multimodal Transportation Planning in Oregon and the Path to Achieving It, 1890-1974." Sources told stories with enthusiastic reference to past transportation events. The structure chosen was an interwoven collection of topical essays, arranged chronologically but skipping sideways, sometimes backward or forward, from stage to stage – national, metropolitan, state governmental, local – but always moving forward in time. The tale presented here takes the reader through tumultuous early years, up to the moment in 1974 when statewide planning goals, including Goal 12, the transportation goal, were adopted by the Oregon Legislature.

  Citation × Citation Citation Abstract Copy Title: Research and Development of a Land Use Scenario Modeling Tool Author: Gliebe, John, Dong, Hongwei, Roll, Josh Frank Year: 2013 Oregon Department of Transportation’s (ODOT) Transportation Planning and Analysis Unit (TPAU) developed a land use modeling tool called the “Land Use Scenario Developer in R” (LUSDR). LUSDR is a modeling tool, written in the “R” language, that may be used to predict and analyze regional land use changes probabilistically, creating a distribution of possible outcomes. It is designed to be integrated with travel demand modeling programs, making it potentially valuable for analyzing the interaction between transportation and land use when assessing various growth-policy and socioeconomic assumptions. This project is Phase 2 for Research and Development of a Land Use Scenario Modeling Tool. It is intended to address several extant deficiencies in the LUSDR modeling tool, each identified below, as a separate research task. The original proposed outcomes of this research were a set of programs, data, and documentation that would comprise a deployable LUSDR package.

  Citation × Citation Citation Abstract Copy Title: Regional Transportation and Land Use Decision Making in Metropolitan Regions: Findings from Four Case Studies Author: Margerum, Richard D., Brody, Susan, Parker, Robert, McEwen, Gail, Moore, Terry Year: 2012 Throughout the United States, metropolitan regions face increasingly complex issues related to transportation and land use. The diffuse nature of decision making creates a need to better coordinate land use and transportation to address issues such as: congestion, infrastructure costs, and greenhouse gas emissions. Key players in this decision making are regional metropolitan planning organizations (MPOs) with transportation planning authority, regional planning responsibilities, and in some cases regional land use planning authority. The goal of this study was to describe and assess efforts by regional agencies to coordinate land use and transportation. Policies and processes in four key topic areas were examined: 1) Governance: formal and informal decision making approaches; 2) Coordination: strategies used to coordinate land use and transportation; 3) Growth Centers: policies to encourage development in higher density centers; and 4) Transportation Improvement Program (TIP): policies to incorporate smart growth criteria in TIP funding decisions.

  Citation × Citation Citation Abstract Copy Title: The "ADaM Cube" : Categorizing Portland, Oregon's Urbanization Using GIS and Spatial Statistics Author: Grotbo, Jeremy Year: 2016 Transportation availability and land use intensity demonstrate a strong relationship, with intense development concentrated near significant transportation investment. Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form and its relationship to urban transportation systems. This research focuses on transportation accessibility, building density, and the structural massing as the basic metrics in the categorization of urban form. Portland, Oregon serves as the case study environment, while the research methodology examines the spatial and statistical relationship between these metrics for much of the city's urban area. Applying geographic information systems (GIS) and k-means cluster analysis, urban form metrics are compared within the ADaM (Accessibility, Density, and Massing) cube, a model demonstrating comparative relationships, as well as the geographic distribution and patterns of urban form in Portland, Oregon's neighborhoods. A finalized urban form catalog describes existing urban environments, but also indicates areas of impending transition, places having the strong potential for reorganization with respect to higher levels of transportation accessibility. The ADaM Cube is a tool for characterizing Portland's existing urban form, and describing the vulnerabilities of urban neighborhoods to the pressure of redevelopment.

  Citation × Citation Citation Abstract Copy Title: Understanding Where We Live and How We Travel Author: Currans, Kristina Marie Year: 2016 Understanding changing residential preferences—especially as they are represented within land use and travel demand models—is fundamental to understanding the drivers of future housing, land use and transportation policies. As communities struggle to address a rising number of social challenges with increasing economic uncertainty, transportation and land use planning have become increasingly centered on assumptions concerning the market for residential environments and travel choices. In response, an added importance has been placed on the development of toolkits capable of providing a robust and flexible understanding of how differing assumptions contribute to a set of planning scenarios and impact future residential location decisions. In this presentation, we discuss one such improvement that can be added to the transportation planning toolkit: an innovative visual online survey tool. This tool was developed to provide a means for researchers to communicate the residential environment to the public. Within this study, we test the ability for the general population to see neighborhood environments consistently. Then we apply this tool within an original data collection, which focuses on examining the residential preferences and trade-offs between neighborhood and commute choices. We discuss the methods developed, lessons learned, and results from the Oregon-based pilot studies testing and applying this new tool.

  Citation × Citation Citation Abstract Copy Title: Planning Transportation for Recreational Areas Author: Dunning, Anne Year: 2016 Population growth and increased accessibility of formerly remote destinations have created new needs for planning mobility to and within recreational areas. Transportation planners studying recreational travel face unusual travel-demand peaks, travelers who are often unfamiliar with their surroundings, and a uniquely important need for traveler and community communication. Planners must consider what characteristics of an individual area make it attractive to visitors, as well as local goals for the special resources of the area. This presentation will characterize unique facets of mobility in recreational areas, and pose approaches to planning transportation systems to serve them.

  Citation × Citation Citation Abstract Copy Title: Edged Out: Location Efficient Housing and Low Income Households in the Portland Region Author: Tremoulet, Andrée, Dann, Ryan Year: 2016 Transportation costs are typically a household’s second largest expense after housing. Low income households are especially burdened by transportation costs, with low income households spending up to two times as much of their income on transportation than higher income households (Litman, 2013). Thus, access to location efficient housing is especially important to low income households, including those who use a housing voucher to help pay for housing costs. This seminar presents the results of a two-year project supported by the Portland region's four public housing authorities to design and test tools to help people with housing vouchers find location efficient housing. We examine the challenges that residents faced and discuss policy implications.
