  Citation × Citation Citation Abstract Copy Title: Transportation Cost Index: A Comprehensive Performance Measure for Transportation and Land Use Systems and its Application in OR, FL, and UT Author: Wang, Liming, Liu, Jenny H Year: 2017 MAP-21 and state laws are placing increasing emphasis on using comprehensive transportation performance measures that include mobility, safety, economy, livability, equity, and environmental to guide transportation decision-making. One of the toughest challenges keeping DOTs and MPOs from adopting comprehensive measures in the decision process is the lack of performance measures allowing consistent comparison of multimodal performance over time and across geographic areas. This project advances a transportation cost index (TCI) initially proposed by Oregon DOT from a proof-of-concept stage to implementation and operational use at the state, MPO, and community levels. After pilot tests and early adoption in Oregon, we test TCI with varying data sources available in different states and make the software more user-friendly. Working with communities in Florida and Utah, we will test and apply TCI to regions in Florida and Utah and compare the patterns of TCI across Oregon, Florida, and Utah.

  Citation × Citation Citation Abstract Copy Title: Parking Infrastructure: A Constraint on or Opportunity for Urban Redevelopment? Author: Chester, Mikhail Year: 2016 Many cities have adopted minimum parking requirements, but we have relatively poor information about how parking infrastructure has grown. In this research, using building and roadway growth models, we estimate how parking has grown in Los Angeles County from 1900 to 2010, and how parking infrastructure evolves, affects urban form, and relates to changes in automobile travel. We find that since 1975, the ratio of residential offstreet parking spaces to automobiles in Los Angeles County is close to 1.0 and the greatest density of parking spaces is in the urban core. Most new growth in parking occurs outside of the core. 14% of incorporated land in Los Angeles County is committed to parking. Uncertainty in our space inventory is attributed to our building growth model, onstreet space length, and the assumption that parking spaces were created as per the requirements. The continued use of minimum parking requirements is likely to encourage automobile use at a time when metropolitan areas are actively seeking to manage congestion and increase transit use, biking, and walking. Widely discussed ways to reform parking policies may be less than effective if planners do not consider the remaining incentives to auto use created by the existing parking infrastructure. Planners should encourage the conversion of existing parking facilities to alternative uses. Title: Parking Infrastructure: A Constraint on or Opportunity for Urban Redevelopment?

  Citation × Citation Citation Abstract Copy Title: California's Paradigm Shift from LOS to VMT as a Transportation Impact Metric: Policies, Politics, and Possibilities Author: Liberty, Robert, Peterson, Lynn Year: 2017 As part of California's effort to reduce greenhouse gas emissions, the state has passed a law leading to a radical shift in how it analyzes the traffic impacts of new land use developments and transportation projects. SB 743's goal is to "more appropriately balance the needs of congestion management with statewide goals related to infill development, promotion of public health through active transportation, and reduction of greenhouse gas emissions." The new measure of transportation impacts will be based on vehicle miles traveled (VMT) instead of level of service (LOS). This ground shift has broad implications for lead agencies, planners, MPOs, and state agencies as they seek to measure and mitigate project-generated, cumulative VMT. The anticipated outcomes are a reduction of GHG emissions, further development of multi-modal transportation networks, and a wide diversity of land uses. Robert Liberty and Lynn Peterson will share what they have learned working with the largest California metropolitan planning organizations to implement this policy change. They will review findings from a case study project; several legal, political, and technical challenges around implementing the new policy; and the possibilities and opportunities ahead for California, with an eye toward its relevance for Oregon and other states.

  Citation × Citation Citation Abstract Copy Title: Do Characteristics of Walkable Environments Support Bicycling? Toward a Definition of Bicycle-Supported Development Author: Muhs, Christopher D., Clifton, Kelly Year: 2016 Does walkability equate with bikeability? Through a comprehensive review of studies of the built environment and bicycling, including mode choice, route choice, safety, and urban design literature, this paper addresses this question. Previous work has raised the issue that the two modes are functionally different, despite them often being combined into a nonmotorized category, and has highlighted research challenges. Existing studies of bikeability have largely focused on infrastructure. This paper contributes to the literature on bicycling and the built environment by providing a thorough review of past research with a focus on the relationships between land use, urban form, and bicycling. Highly walkable and highly bikeable environments are quite different, and there is little consistency in the built-environment attributes associated with cycling across studies. We postulate that this inconsistency is due in part to a disconnect between theory and methods of measuring the environment for cycling along with data limitations, including sample sizes and our understanding being based mainly on cross-sectional data. Many research opportunities are present for land-use planning policies now that planning for cycling is a top priority for cities and regions across the world.

  Citation × Citation Citation Abstract Copy Title: Regional Planning, Greenhouse Gases, and UrbanFootprint Open Source Software Author: Woodsong, Garlynn Year: 2014 Since about 2008, the planning world has been experiencing a paradigm shift that began in places like California and Oregon that have adopted legislation requiring the linking of land use and transportation plans to outcomes, specifically to the reduction of greenhouse gases (GHGs). In response to this need, Calthorpe Associates has developed a new planning tool, called UrbanFootprint, on a fully Open Source platform (i.e. Ubuntu Linux, PostGIS, PostGreSQL, etc.). As a powerful and dynamic web and mobile-enabled geo-spatial scenario creation and modeling tool with full co-benefits analysis capacity, UrbanFootprint has great utility for urban planning and research at multiple scales, from general plans, to project assessments, to regional and state-wide scenario development and analysis. Scenario outcomes measurement modules include: a powerful ‘sketch’ transportation model that produces travel and emissions impacts; a public health analysis engine that measures land use impacts on respiratory disease, obesity, and related impacts and costs; climate-sensitive building energy and water modeling; fiscal impacts analysis; and greenhouse gas and other emissions modeling.

  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: Tools for Assisting Low-Income Households with Finding Location-Efficient Housing Author: Tremoulet, Andrée Year: 2016 Through a previously funded research project, Encouraging Low-Income Households to Make Location-Efficient Housing Choices, our team developed a toolkit to assist households utilizing Section 8 Housing Choice Vouchers with finding location-efficient/affordable housing. These tools are currently in use by the region’s four public housing authorities (PHAs). This technology transfer project provided the tools to social service providers who work with voucher recipients in the Portland region and provided a presentation on research findings and policy implications to transportation researchers, professionals and students. Specific activities included: • In-person presentations to groups of social service providers in three counties (four presentations total) who provide case management and other intensive social services for households with low incomes. • A TREC-sponsored presentation/webinar as part of the TREC Friday Transportation Seminar series In addition, final edits were completed on a manuscript included in Housing Policy Debate’s special issue on location-affordable housing. Additional research was begun on a manuscript for submission to the Transportation Research Board.

  Citation × Citation Citation Abstract Copy Title: Integrative Public Transport in a Segmented City: Reflections from Jerusalem Author: Cohen-Blankshtain, Galit Year: 2016 Jerusalem is perhaps an extreme case of residential and travel market segmentation. It is comprised of four different 'cities', which partially overlap in space: The Jewish-Zionist city; the Palestinian city; the Jewish ultra-orthodox city and the global-tourist city. While the specific delineation of these cities is unique, Jerusalem can be seen as representative of other cities where ethnic and religious tensions create highly segmented urban spaces and travel markets. In recent years particular emphasis has been placed on integrating transport systems, both across modes and with land use, in order to facilitate and encourage the use of public transport. Spatial integration suggests overcoming cultural and social differences that may be reflected with the units that are to be coordinated. Spatial integration calls for minimizing differences among geographical unites in order to create a comprehensive, full network transport system with economy of scale. Therefore, there might be tradeoffs between integration and another highly recognized transport goal: responsiveness. Responsiveness in highly segmented cities often involves political intervention that limits the integrative approach.
