  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: 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.

  Citation × Citation Citation Abstract Copy Title: Determinants of Recent Mover Non-work Travel Mode Choice Author: Adkins, Arlie Steven Year: 2014 Active transportation modes of walking and bicycling have the potential to help mitigate environmental and health concerns ranging from growing greenhouse gas emissions to increasing rates of obesity. This dissertation investigates how new movers make decisions about active transportation, particularly non-work utilitarian walking, in the context of a new home and neighborhood. New movers are an important, yet often overlooked, population in travel behavior research because they provide an opportunity to observe behavior adoption in new contexts, but also because the roughly one-in-ten Americans who move each year are more likely to consider changes to daily routines, including travel behavior, making them prime targets for voluntary travel behavior change programs. Using data from a two-wave survey of recent movers in six U.S. cities, psychological and social mechanisms essential to the built environment travel behavior relationship. The research is divided into three stand-alone papers (chapters 4, 5 and 6). First, to isolate the built environment effect on active travel mode adoption, the relative influence of the built environment and a robust set of self-selection variables is quantified. Second, the psychological constructs that facilitate the built environment travel behavior relationship are identified. And in light of increasing market demand for housing in walkable urban neighborhoods and the observed importance of self-selection, the final paper quantifies the extent to which low-income households face are able to realize preferences for walkable housing locations. The key findings of this dissertation are that 1) the built environment plays a key role in determining recent mover adoption of utilitarian walking even after controlling for self-selection; 2) the influence of the built environment on post-move adoption of utilitarian walking largely mediated by perceived behavior control, as expected, and, unexpectedly, by descriptive social norms; and 3) low-income movers who prioritized moving to a walkable place were about half as likely as higher-income movers to be able to realize this preference. These findings have practical and theoretical implications which are discussed in each paper and in the final chapter.

  Citation × Citation Citation Abstract Copy Title: Peer-To-Peer Carsharing: Short-Term Effects on Travel Behavior in Portland, OR Author: Dill, Jennifer, McNeil, Nathan, Howland, Steven Year: 2017 Peer-to-peer (P2P) carsharing is a relatively new concept in the U.S. Enabled by recent internet and mobile technology development, P2P carsharing generally involves a facilitating company connecting private vehicle owners to people who are interested in renting a vehicle. P2P carsharing has many things in common with business-to-consumer (B2C) carsharing services. Consumers join the service to rent vehicles on a short-term basis from locations dispersed throughout a certain area. Both services may allow households to reduce their private car ownership. However, P2P carsharing differs substantially from other models in that there are two distinct sets of consumers: those who rent the vehicles (renters) and those who put their vehicles up for rent (owners). The members of the service are providing the supply as well as the demand. Not only does the car owner provide the vehicle and determine where it is parked, they determine what hours it is available for rent and at what price (though with some influence from the facilitating company). This report presents findings from a multiyear study of P2P carsharing that began in early 2012 and targeted members of Getaround, which launched in February 2012 in Portland, OR. The goal of this study, which collected information from both owners and renters, is to evaluate the impact of peer-to-peer carsharing relative to other models of car use, including ownership, rental, and conventional (corporate) carsharing. The two primary research questions are whether P2P carsharing can reduce overall and peak- period vehicle miles traveled (VMT) by marginalizing the cost of driving, and whether P2P carsharing increases access to jobs and other activities for those without cars. Compared with conventional carsharing, P2P carsharing has the potential to influence VMT for both the renter and the owner. P2P owners may reduce their driving so that the vehicle is available for rent. Renters, as with other forms of carsharing, may decide to forgo or reduce vehicle ownership and drive less because the marginal costs of driving are more apparent. This report also examines motivations and factors associated with greater or lesser participation (in terms of rental activity), the influence of P2P carsharing on travel behavior and attitudes toward car ownership, and general experiences with P2P carsharing Title: Peer-To-Peer Carsharing: Short-Term Effects on Travel Behavior in Portland, OR Author: Dill, Jennifer, McNeil, Nathan, Howland, Steven Year: 2017 Peer-to-peer (P2P) carsharing is a relatively new concept in the U.S. Enabled by recent internet and mobile technology development, P2P carsharing generally involves a facilitating company connecting private vehicle owners to people who are interested in renting a vehicle.

  Citation × Citation Citation Abstract Copy Title: Webinar: Economic Impacts from Bicycle and Pedestrian Street Improvements Author: Liu, Jenny H. Year: 2017 As many cities are investing in street improvements to provide better biking and walking experiences, the economic value and impacts of these active transportation facilities remain areas where many practitioners, planners and policy makers are seeking more conclusive evidence. With various modes competing for scarce resources, planners and transportation agencies often struggle with how to justify infrastructure investments for non-motorized modes, particularly when driving is still the predominant mode of transportation in most cities. In this project we assess property value impacts of Portland’s “Green Loop” signature bike infrastructure concept, illustrating the importance of considering both accessibility and extensiveness of bike facility networks. The Green Loop is a proposed 6-mile linear open space running through the heart of Portland, connecting existing and new open spaces, parks, gathering areas, and walking and biking pathways. As envisioned, the Green Loop concept requires significant infrastructure investments, and would result in both short-term and long-term impacts on transportation (for all travel modes), economic development and the environment. In collaboration with the Portland Bureau of Planning and Sustainability (BPS), the Portland State University Institute for Sustainable Solutions (ISS), and in partnership with PeopleForBikes and the Summit Foundation, the goal of this research is to characterize, quantify and analyze these costs, benefits and impacts, particularly focusing on case studies of similar infrastructure investments in active transportation. In this webinar, we will further focus on the residential property value impacts associated with advanced bike facilities. We find that proximity to advanced bike facilities has significant and positive effects on all property values, highlighting household preferences for high quality bike infrastructure. The lessons and research gaps identified in this work led to the development of two ongoing NITC-funded studies: "Understanding Economic and Business Impacts of Street Improvements for Bicycle and Pedestrian Mobility - A Multi-City Multi-Approach Exploration" and "Understanding the economic impacts of urban greenway infrastructure." We will share some updates on these ongoing projects as well. Key learning outcomes include: A framework for understanding the economic results of bicycle and pedestrian investments, with data to show: Evidence of impacts on residential property values Evidence of impacts on on business and retail activity Insight into potential short-term and long-term impacts of the Portland Green Loop A method for estimating economic impacts of similar proposed active transportation projects Title: Webinar: Economic Impacts from Bicycle and Pedestrian Street Improvements Author: Liu, Jenny H.

  Citation × Citation Citation Abstract Copy Title: Breaking Barriers to Bike Share: Insights from Residents of Traditionally Underserved Neighborhoods Author: McNeil, Nathan, Dill, Jennifer, MacArthur, John, Broach, Joseph, Howland, Steven Year: 2017 Evidence has shown that higher income and white populations are overrepresented in both access to and use of bike share. Efforts to overcome underserved communities’ barriers to access and use of bike share have been initiated in a number of cities, including those working with the Better Bike Share Partnership (BBSP) to launch and test potentially replicable approaches to improve the equity outcomes. This report describes findings from a survey of residents living near bike share stations placed in underserved communities of select BBSP cities: Philadelphia, Chicago, and Brooklyn. These were neighborhoods targeted for focused outreach related to BBSP programs, and were majority-minority (79- 94% people of color) and lower-income (36-61% of households under 150% of the poverty level). Residents were also surveyed in control areas that did not receive BBSP targeted outreach in two of the cities. The research team mailed surveys to 6,000 residents in each city, and received 1,885 responses. Respondents closely matched area demographics on race/ethnicity and income in most study locations, but were somewhat more likely to be women, older and more highly educated. Findings are drawn primarily from an analysis of data from adults in the BBSP outreach areas under 65 years old and physically able to ride a bicycle. Of those respondents who provided race and income information (n=779), 42% were lower-income (defined as 300% of poverty or below) people of color, 27% were higher-income (above 300% of poverty) people of color, 6% were lower-income and white (not Hispanic), and 25% were higher-income and white. Race and income often influenced responses to bicycling and bike share in different ways. Differences in behavior and opinions sometimes correlated with income, sometimes with race, and sometimes with race and income combined. Both people of color and lower-income residents cited more barriers to bicycling generally and to using bike share than did higher-income white residents. The biggest barrier to bicycling generally is concern about traffic safety, regardless of race or income (cited as a big barrier by 48% of residents). For some, personal safety is also a concern. For example, 22% of lower-income people of color stated that a big barrier to riding was that doing so could cause them to be harassed or a victim of crime. Some of the most common barriers to bicycling cited by lower-income people of color were issues that bike share could address, such as: not having a bike or related gear (47%); not having a safe place to leave a bike where they need to go (36%); the expense of buying a bike or related gear (41%); and not having a safe place to store a bike at home (32%). High costs of membership and concerns about liability for the bicycle were big barriers to using bike share for about half of lower-income respondents (48% and 52% respectively), compared to 33% and 31% of higher-income respondents of color and only 18% and 10% of higherincome white respondents. Another set of barriers relates to knowledge, lack of knowledge or incorrect knowledge. Only 31% of all respondents knew the details about the availability of the reduced-price membership or pass option, and 34% of lower-income respondents of color said that not knowing enough about how to use bike share was a big barrier to using it, compared to 19% of higher-income respondents of color and 7% of higher-income white residents. Among potential program changes, lower-income people of color were significantly more likely than other respondents to indicate that certain changes would make them more likely to use bike share, including: several changes that could help with cost and liability concerns such as discounted membership or use options (80% stating somewhat or much more likely to use bike share with this change), access to free or low-cost helmets/gear (72%), and easier ways to pay with cash (67%); and several changes to help overcome knowledge or experience gaps, such as help finding safe ways to get where I need to go (70%), and organized rides for people like me (71%). Respondents generally have positive attitudes about bicycling and bike share. A large majority of all residents (73%) and lower-income people of color (74%) agreed that the city’s bike share system “is useful for people like me.” In terms of reasons for using bike share, getting exercise was cited by 71% of the lower-income respondents of color as a reason they would consider using bike share, a rate much higher than other respondent groups. Being able to ride with friends and family was cited by 48% of lower-income respondents of color, again higher than other groups.
