  Citation × Citation Citation Abstract Copy Title: Co-Evolution of Transportation and Land Use: Modeling HIstorical Dependencies in Land Use and Decision-Making Author: Zhang, Lei, Zu, Wei, Li, Mingxin Year: 2009 The interaction between land use and transportation has long been the central issue in urban and regional planning. Models of such interactions provide vital information to support many public policy decisions, such as land supply, infrastructure provision, and growth management. Both the transportation and land use systems exhibit historical dependencies in policy decisions. For instance, the expansion of a roadway today will change travel demand patterns, and make certain other roads more or less likely to be expanded in the future. A specific land supply decision made at one point in time, by changing the relative attractiveness of other areas in the region, can have a profound impact on future land supply decisions. Today’s land use decisions clearly influence future transportation policies and vice versa. This project examines the land use-transportation interaction from an evolutionary perspective — once a certain set of goals are determined and pursued by politicians and planners, their land supply and transportation investment decisions are, to a large extent, driven by their previous decisions and supply-demand dynamics in the urban system. Built upon this recognition of historical dependency and a transportation network growth model previously developed by the P.I., a model of the co-evolution of land use and transportation is proposed in this project. Different from existing integrated land use and transportation models that assume exogenous network investment decisions, the co-evolution model considers both land use growth and transportation network growth as endogenous and market-driven. The central research question is how market and policies translate into transportation facilities and land use developments on the ground. The co-evolution model achieves an Urban Growth Equilibrium, which is a useful concept for planning and policy analysis. An agent-based simulation approach is employed to integrate an existing land use model and the transportation network growth model.

Bureau of Planning Year: 2000 All four plans were comprehensive. Their scope included transportation, housing, economic development, parks and open space, natural resources, urban design, and land use. Large scale planning efforts had previously focused on a limited set of concerns, such as parking, commercial revitalization, or housing. The Downtown Plan, Central City Plan, Albina Community Plan, and Outer Southeast Community Plan, on the other hand, evaluated, balanced, and integrated the different elements so that each action was taken in light of its effect on others. Extensive citizen involvement shaped the content of these plans and contributed to their success.

  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: Continuous Data Integration for Land Use and Transportation Planning and Modeling Author: Wang, Liming, Kim, Kihong Year: 2014 There is an urgent need for improved models that address the interdependencies between land use and transportation, and considerable new work is underway to develop such models in Oregon and elsewhere. These models and planning practices to integrate land use into the process, however, require the integration of massive amounts of land use data that is messy and incomplete. There have been considerable advances in the treatment of such data problems in other domains, drawing on data mining and machine-learning techniques to address issues in various domains. To date, however, little systematic effort has applied these technological advances to the problem domain of land use and transportation data. Experience suggests that as much as 70% of the total effort in developing integrated land use and transportation models is directly or indirectly associated with data development, integration and cleaning, yet there is remarkably little systematic research focused on the development of reusable methods and tools to support this problem domain. In coordination with an ongoing project of similar theme funded by University of California Transportation Center (UCTC), this project will focus on bringing interdisciplinary methods to develop land use datasets for integrated land use and transportation planning and modeling, with special attention on preserving temporal dimension of the data and monitoring data quality through indicators. Utilizing statistics and machine-learning techniques, we will develop reusable tools that will create a harmonized and coherent land use database from various public and private sources. These tools will be made available to the public and can be used by cities, counties, metropolitan planning agencies, state agencies, universities or anyone else needing to develop a usable database for use in integrated planning and modeling. All of the resulting data, with the exception of proprietary or confidential input data where there is no viable alternative, would be public and reusable for planning and research.

  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: An Activity-related Land Use Mix Construct and Its Connection to Pedestrian Travel Author: Gehrke, Steven R. Year: 2016 Land use mix is a central smart growth principle connected to active transportation. This presentation describes the indicators of local land use mixing and their association with pedestrian travel in Oregon’s Willamette River Valley. It argues that land use mix is a multidimensional construct reflected by the complementarity, composition, and configuration of land use types, which is positively linked to walk mode choice and home-based trip frequency. Findings from this study underline the conceptual and empirical benefit of analyzing this transportation-land use interaction with a landscape pattern measure of activity-related composition and spatial configuration.

  Citation × Citation Citation Abstract Copy Title: Land Use and Growth Impacts from Highway Capacity Increases Author: Sanchez, Erik J Year: 2000 This analysis examined the historical relationship between land use changes and the location of capacity increasing highway projects in the State of Oregon from 1970 to 1990. Aerial photography for 18 cities was used to delineate the extent of urban development in each time period. A geographic information system (GIS) was used to assemble the data. Using this data, a logit regression model tested the significance of geographic variables such as proximity to highway projects, land use zoning classification, city size, and other spatial characteristics. The analytical methods used in this study incorporated a set of commonly used techniques to assess highway impacts on urban development patterns. The results suggest that for the 18 selected cities, the spatial measures performed well in predicting the location of urban development from 1970 to 1990. In addition, the results of the logit regression model indicated that controlling for other location factors, urban development had not clustered along state high project corridors as was suspected.
