  Citation × Citation Citation Abstract Copy Title: Track Time and Monetary Costs of Transportation as a Comprehensive Performance Measure: Development and Application of Transportation Cost Index Author: Wang, Liming Year: 2016 As federal and state policies place increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making, there is a gap in such measures of transportation and land use systems. This seminar reports the results from a research project aiming to fill the gap in the type of applications and policy areas covered by existing measures. Modeled after the popular Consumer Price Index, the project refines and develops a transportation cost index (TCI) measure for transportation and land use systems by tracking the time and monetary costs of transportation for households as they travel to satisfy their daily needs. The TCI can be used in applications ranging from monitoring historical and projected trends (benchmarking), to evaluating and comparing scenarios outcomes (scenario evaluation), and it is capable of representing policy areas not sufficiently covered by existing similar measures. The seminar will review similar performance measures, describe the rationale, design and implementation of TCI, and present results of its applications in Portland and Corvallis, Oregon, as well as nation-wide in the US. The project is sponsored by National Institute of Transportation Communities (NITC) and Oregon DOT.

  Citation × Citation Citation Abstract Copy Title: Who is Making Ends Meet in the Portland Region? A Profile of Poverty and Self-Sufficiency among Greater Portland Families Author: Kimmell, Jamin, Martin, Sheila A. Year: 2015 The Portland metro region economy is near a complete recovery from the damage of the Great Recession that began seven years ago. Unemployment in April of 2015 was 5.2 percent, cut in half from the 2011 rate of 10.5 percent. The region ranked among the top 10 metro region areas in the nation for employment growth in 2014. Unfortunately, the benefits of this economic resurgence are not experienced equally. Ideally, economic recovery should lead to jobs and wages that enable Portland metro region families to earn enough to provide for their basic needs. Low unemployment cannot offer high quality of life if the jobs available do not pay adequate wages to make ends meet. Furthermore, public and nonprofit organizations are burdened by the demand on social services caused by families that cannot earn enough to cover basic needs like food, housing and health care. Many families in the Portland region do not earn adequate income to make up for the rising costs of life’s necessities, and self-sufficiency eludes far more families than is indicated by federal poverty statistics. Households headed by women or people of color, and families with children, are highly overrepresented among those who cannot make ends meet. Education can close part of this racial and gender gap, but it is not a panacea; other barriers persist for those families who are least likely to attain self-sufficiency. This study is a demographic analysis of self-sufficiency in the Portland metro region. Title: Who is Making Ends Meet in the Portland Region?

  Citation × Citation Citation Abstract Copy Title: Planning Ahead for Livable Communities Along the Powell-Division BRT: Neighborhood Conditions and Change Author: Bates, Lisa K., Golub, Aaron, Macarthur, Devin, Sung, Seyoung Year: 2017 New transit investments can be a double-edged sword for disadvantaged communities (e.g., those included in environmental justice and Title VI protected classes). Transit investments improve communities’ mobility and access, and may improve health with reduced driving. However, there is also the potential for transit-oriented development (TOD) to spur gentrification and displacement if affordable housing is lost. Understanding transit corridor conditions and change with new infrastructure is important for learning how to mitigate negative effects and support inclusive communities with access to transit for lower-income households. The planning of a new bus rapid transit line along the Powell-Division corridor in Portland-Gresham provides an opportunity to understand neighborhood impacts of transit investment and evaluate programs designed to preserve and create affordable housing; include residents in economic development on the corridor; and build livable communities in an underserved area of the region. This proposal is for a research partnership between Toulan School of Urban Studies and Planning faculty and the Portland Bureau of Planning and Sustainability to evaluate current conditions and potential for impacts of TOD, and to build a long-term program of assessment of neighborhood change and program evaluation as the city pilots new approaches to equitable TOD. The first phase will document the potential costs to communities if an integrated approach to livable communities were not taken, by assessing the risk of housing loss and displacement. DOT priorities are developing, evaluating and disseminating a coordinated approach to livable communities that includes housing and transportation. This work will speak to the scholarly debates about gentrification and public infrastructure investment, and will be presented to practitioner audiences through venues such as New Partners for Smart Growth, the PolicyLink think tank, and other learning opportunities for professionals.

  Citation × Citation Citation Abstract Copy Title: A Pathway Linking Smart Growth Neighborhoods to Home-Based Pedestrian Travel Author: Gehrke, Steven R., Clifton, Kelly J. Year: 2017 Land development patterns, urban design, and transportation system features are inextricably linked to pedestrian travel. Accordingly, planners and decision-makers have turned to integrated transportation-land use policies and investments to address the pressing need for improvements in physical activity levels via the creation of walkable communities. However, policy questions regarding the identification of smart growth indicators and their connection to walking remain unanswered, because most studies of the built environment determinants of pedestrian travel: (a) represent the built environment with isolated metrics instead of as a multidimensional construct and (b) model this transportation-land use relationship outside of a multidirectional analytic framework. Using structural equation modeling, this Portland, Oregon study identifies a second-order latent construct of the built environment indicated by land use mix, density, and urban design and transportation system features. Study findings suggest this construct has a strong effect on the household-level decision to walk for transport and discretionary travel.

  Citation × Citation Citation Abstract Copy Title: Cultivating (a) Sustainability Capital: Urban Agriculture, Eco-Gentrification, and the Uneven Valorization of Social Reproduction Author: McClintock, Nathan Year: 2017 Urban agriculture (UA), for many activists and scholars, plays a prominent role in food justice struggles in cities throughout the Global North, a site of conflict between use and exchange values, and rallying point for progressive claims to the right to the city. Recent critiques, however, warn of its contribution to gentrification and displacement. The use/exchange value binary no longer as useful an analytic as it once was, geographers need to better understand UA’s contradictory relations to capital, particularly in the neoliberal Sustainable City. To this end, I bring together feminist theorizations of social reproduction, Bourdieu’s “species of capital”, and critical geographies of race to help demystify UA’s entanglement in processes of eco-gentrification. In this primarily theoretical contribution, I argue that concrete labor embedded in household-scale UA—a socially reproductive practice—becomes cultural capital that a Sustainable City’s growth coalition in turn valorizes as symbolic sustainability capital used to extract rent and burnish the city’s brand at larger scales. The valorization of UA occurs, by necessity, in a variegated manner; spatial agglomerations of UA and the eco-habitus required for its misrecognition as sustainability capital arise as a function of the interplay between rent gaps and racialized othering. I assert that eco-gentrification is not only a contradiction emerging from an urban sustainability fix, but is central to how racial capitalism functions through green urbanization. Like its contribution to eco-gentrification, I conclude, UA’s emancipatory potential is also spatially variegated.

  Citation × Citation Citation Abstract Copy Title: Developing High-Resolution Descriptions of Urban Heat Islands: A Public Health Imperative Author: Voelkel, Jackson, Shandas, Vivek, Haggerty, Brendon Year: 2016 Extreme heat events affect the most vulnerable human populations and are a lethal health hazard to urban dwellers globally; in the United States, extreme heat causes more deaths annually than all other weather events and natural hazards combined (1). Previous studies described urban heat islands as isolated, static, monolithic areas of cities. We challenged this contention by hypothesizing that diurnal temperature cycles and diverse landscape features create variation in places that amplify heat (2). A temporal description of urban heat islands would identify populations that are susceptible to heat stress, particularly at night, when most people are asleep and unable to regulate internal body temperatures. If public health agencies are to prevent illness and death caused by heat, they will need to know which populations are most vulnerable to heat stress, particularly at night; such information can guide timely interventions (3). Researchers lack high-resolution tools for identifying neighborhoods and households where extreme weather events might have profound and fatal effects on human health. The objective of this study was to use spatial analytics at previously unattained resolutions to answer the following research question: to what extent can we observe temporal variation in urban heat islands and the physical features that induce heat stress?

Over the past decade, substantial attention has been paid to one national set of guidelines—the Institute of Transportation Engineers (ITE) Trip Generation Handbook (2014) and corresponding Manual (2012)—focusing in particular to improve the use of these data and supplementary methods for urban contexts. The purpose of this study is to explore the typical data provided in the Handbook, within the context of these new improved state-of-the-art methods. As ITE’s describes, “an example of poor professional judgment is to rely on rules of thumb without understanding or considering their derivation or initial context” (Institute of Transportation Engineers, 2014, p. 3). This research aims to improve the understanding of these data—still ubiquitously used across the US—to encourage increased engagement with their meaning, and following, to provide the users (e.g., engineering, planners, agencies, and developers) with the landscape from which these data were collected and for which they represent. From here, more informed decisions can be made about whether these data provide an adequate or accurate estimation transportation impacts within varying contexts and applications.

  Citation × Citation Citation Abstract Copy Title: Environmentally Sustainable and Affordable Housing Near Transit in Los Angeles Author: Boarnet, Marlon Year: 2017 Providing affordable housing and reducing greenhouse gases are common goals in cities worldwide. Transit-oriented development (TOD) can provide an opportunity to make incremental progress on both fronts, by building affordable housing near transit and by providing alternative transport modes such that households reduce driving. While the existing literature has focused on the relationship between TOD and housing and TOD and greenhouse gas emission reduction as separate issues, it has seldom touched on the possibility that TOD could address both goals jointly. We provide evidence to show that focusing on either housing affordability or greenhouse gas emission reduction in isolation can lead to strategies that achieve one goal to the detriment of the other. Using the case of Los Angeles, we develop a scenario planning model that allows simultaneous consideration of housing and transportation goals, and illustrates the tradeoffs of different policy approaches. The results show that larger increases in residential densities combined with a small inclusionary housing requirement yields greater benefits, in terms of both reduced driving and more affordable housing, than would a higher inclusionary percentage with smaller increases in density.

  Citation × Citation Citation Abstract Copy Title: Who Uses Peer-to-Peer Carsharing? Early Exploration Author: Mathez, Anaïs Year: 2015 Peer-to-peer (P2P) carsharing is a system where a facilitating company connects car owners to car renters. Such systems are relatively new in the U.S. This paper aims to understand who is participating in P2P carsharing as a renter (as opposed to as an owner), why they join, whether and how often they rent vehicles, and why. Exploring these questions may provide insight on the potential for P2P carsharing to meet public policy objectives of reducing the impacts of personal vehicle ownership and use and providing mobility options for underserved populations. The analysis is based on 465 study participants who enrolled in a P2P carsharing service in Portland, Oregon during its first two years of operation (February 2012 to June 2014). The data, which come from a series of online surveys, are part of an on-going, multi-year research project and, as such, should be considered early findings. The people who joined P2P carsharing and this study tend to be younger and well-educated, consistent with research on traditional carsharing. Given two trends in vehicle ownership – the longstanding positive correlation with income and the emerging trend of younger Americans eschewing vehicle ownership in greater numbers than before - we created a typology of potential P2P renters to explore reasons for joining and the potential influence of P2P carsharing on vehicle ownership and mobility. The typology consists of: (1) Student Millennials,(2) Non-student Millennials, (3) Lower Income Non-millennials, and (4) Higher Income Non-millennials. Study participants were highly motivated to join simply because they like the idea of P2P carsharing. Not surprisingly, the Higher Income Non-millennials were less motivated by economic reasons. By June 2014, just over half (52%) of the study participants had rented a vehicle through the service. Actual use of the service is negatively correlated with car ownership. There are some early indications that the service may be expanding mobility options for lower income households. Title: Who Uses Peer-to-Peer Carsharing?

  Citation × Citation Citation Abstract Copy Title: Impact of Bike Facilities on Residential Property Prices Author: Shi, Wei Year: 2017 As many cities are investing in street improvement or transportation infrastructure upgrade projects to provide better bike access or more complete bike networks, the economic value of bike infrastructure and bike facilities remains an area where many practitioners, planners and policy makers are seeking more conclusive evidence. Using residential property values as indicators of consumer preferences for bicycle infrastructure, this study focuses on advanced bike facilities which represent higher levels of bike priority or bike infrastructure investments that have been shown to be more desirable to a larger portion of the population. Estimating ordinary least squares hedonic pricing models and spatial autoregressive hedonic models separately for single and multi-family properties, we find that proximity to advanced bike facilities (measured by distance) has significant and positive effects on all residential property values, highlighting household preferences for high quality bike infrastructure. Furthermore, we also show that the extensiveness of the bike network (measured by density) is a positive and statistically significant contributor to the property prices for all residential property types, even after controlling for proximity to bike facilities and other property, neighborhood and transaction characteristics. Finally, estimated coefficients are applied to assess property value impacts of a proposed Portland “Green Loop” signature bike infrastructure concept, illustrating the importance of considering both accessibility and extensiveness of bike facility networks.
