Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan Mcneil, Jennifer Dill, John Macarthur

TREC Webinar Series

While the number of public bike share systems in the United States grew considerably in recent years, early evidence indicated that many systems were not serving the diverse populations of cities, particularly lower-income residents and people of color. Lack of bike share stations in neighborhoods with people of color and/or lower incomes is one factor; however, considerable disparities appear to persist even when stations are placed in these communities.

Efforts to overcome access and use barriers (such as cost, payment options, and familiarity with the system) to bike share for underserved communities have been initiated in a number of cities. …

Tod Beats Tad In Affordability Showdown, Brenda Scheer

TREC Project Briefs

A research project compares transportation affordability between transitoriented development (TOD) and transit-adjacent development (TAD).

How Does Transportation Affordability Vary Among Tods, Tads, And Other Areas?, Brenda Scheer, Reid Ewing, Keunhyun Park, Shabnam Sifat Ara Khan

TREC Final Reports

Transit-oriented development (TOD) has gained popularity worldwide as a sustainable form of urbanism; it concentrates development near a transit station so as to reduce auto-dependency and increase ridership. Existing travel behavior studies in the context of TOD, however, are limited in terms of small sample size, inconsistent TOD classification methods, and failure to control for residential self-selection. Thus, this study has three research questions. First, how can we distinguish between Transit-oriented development (TOD) and Transit-adjacent development (TAD)? Second, how do travel behaviors vary between TODs and TADs? Third, how does transportation affordability vary between TODs and TADs? This study utilizes …

Talking The Walk: An Autoethnography Of Pedestrianism In Chicagoland, Andrew Kuka

Student Research – Stevenson Center

This autoethnographic account of pedestrianism in Chicagoland aims to remind us of the sensory, social, and emotional experiences walking can provide, and how an environment centered around automobiles affects those experiences. It utilizes participant observations and refers to literature from a wide range of disciplines to construct a story of walks in downtown Aurora and Chicago, Illinois that illuminates factors at play in the shaping of the pedestrian experience in urban areas.

Webinar: Land Use Mix And Pedestrian Travel Behavior: Advancements In Conceptualization And Measurement, Steven R. Gehrke

TREC Webinar Series

Smart growth policies have often emphasized the importance of land use mix as an intervention beholding of lasting urban planning and public health benefits. Past transportation-land use research has identified potential efficiency gains achieved by mixed-use neighborhoods and the subsequent shortening of trip lengths; whereas, public health research has accredited increased land use mixing as an effective policy for facilitating greater physical activity.

However, despite the celebrated transportation, land use, and health benefits of improved land use mixing and the extent of topical attention, no consensus has been reached regarding the conceptualization and measurement of this key smart growth principle …

When Cities Shrink, Affordability Does Too, Joanna Ganning, Jenna Rosie Tighe

TREC Project Briefs

To better understand the real costs of housing and transportation in a declining urban context, NITC researchers implemented a household survey to determine whether the assumptions made in existing research literature and in the LAI regarding household expenditures and transportation accessibility hold true when analyzing shrinking cities—generally, cities characterized by a long-term loss in occupied housing units. The project was led by Joanna Ganning of Cleveland State University, who has conducted previous research into shrinking cities with the support of the NITC program.

Impacts Of Bus Rapid Transit (Brt) On Surrounding Residential Property Values, Victoria Perk, Martin Catalá, Maximillian Mantius, Katrina Corcoran

TREC Final Reports

As bus rapid transit (BRT) grows in popularity in the United States, a better understanding of the mode’s impacts on land uses and property values is needed. Economic theory suggests, and literature has shown, that people are willing to pay higher housing costs to lower their costs of transportation to areas of economic activity. Does high-quality BRT service reliably provide such access and, thereby, increase residential property values? The hypothesis is that property values are higher closer to BRT stations, reflecting a premium for the access provided by the BRT service to various goods, services, employment, education, and recreation. There …

Homes Close To Fast Transit: The Value Is Still Rising, Victoria Perk, Martin Catalá, Maximillian Mantius, Katrina Corcoran

TREC Project Briefs

This research contributes to the relatively small body of literature on property value impacts of BRT in the U.S. by conducting a case study on Lane Transit District’s EmX BRT service in Eugene, Oregon, using econometric modeling techniques to estimate changes in property values associated with the BRT. The analysis is based on hedonic price regression analysis, where sale prices are modeled using several property characteristics that contribute to the market or sale price. The findings of this research indicate that the EmX BRT system does positively impact surrounding single-family home sale prices.

New Transit Developments: A Double-Edged Sword, Lisa K. Bates, Aaron Golub, Devin Macarthur, Seyoung Sung

TREC Project Briefs

Researchers analyze the projected impacts of a proposed transit investment on affordability and mobility in a Southeast Portland corridor.

What Do We Know About Location Affordability In U.S. Shrinking Cities?, Joanna Ganning, Jenna Rosie Tighe

TREC Final Reports

In late 2013, the Department of Housing and Urban Development (HUD) launched the Location Affordability Index (LAI) portal. Their dataset uses models to estimate typical amount households spend on housing and transportation at the block group level, and calculates “H + T Affordability,” the percent of household income spent on these items. In our previous research, we analyzed 81 shrinking cities to determine how location affordability differs across various neighborhoods. Our results suggest that households in declining neighborhoods, as compared to stable or redeveloping neighborhoods, face the greatest H + T affordability challenges in shrinking cities. Furthermore, in declining neighborhoods, …

Planning Ahead For Livable Communities Along The Powell-Division Brt: Neighborhood Conditions And Change, Lisa K. Bates, Aaron Golub, Devin Macarthur, Seyoung Sung

TREC Final Reports

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 …

The Geography Of The Commute, Steven Howland, Randy Morris

Metroscape

It is a common misperception that low-income populations are transit-dependent or typically do without a car because it is too expensive. While much larger proportions of low-income populations use a mode of transportation other than a personal automobile to commute to work, a majority of them still use a personal automobile. In this edition of the Periodic Atlas, we looked at commuting as it relates to people of color and low-wage workers using the most recent reliable Census data as well as data from the Longitudinal Employer-Household Dynamics Origin-Destination Employment Statistics (LEHD-LODES).

China's Motorization Wave And The Place Of Emerging Technologies, Christopher Cherry

PSU Transportation Seminars

E-bikes, E-Cars, Carshare, Bikeshare, and Micro-EVs in China have shaken up the traditional motorization pathways that have occurred in developing countries in the past. The combination of emerging vehicle technologies, urban and environmental constraints, and heavy-handed policy make China's motorization processes unique in the world—but how China motorizes has far-reaching impacts based on sheer volume of vehicles and population.

This seminar discusses the results of a six-year NSF CAREER project to explore China's motorization processes, combining behavioral and environmental modeling approaches to assess the impacts of emerging vehicle technologies on motorization and ultimately environmental sustainability. The focus is mostly on …

Measuring The Impacts Of Social Media On Advancing Public Transit, Jenny H. Liu, Xuegang Ban, O. A. Elrahman

TREC Final Reports

This project is a collaboration between Portland State University (PSU) and the Center for Infrastructure Transportation & Environment (CITE) at Rensselaer Polytechnic Institute seeking to develop performance measures for assessing the impacts of social media on promoting public transit. Revolutionary changes have occurred in the communication landscape, and there has been a rapid diffusion of social media use as a means of communicating transit information to the public. Significant resources are being directed to the use of social media in communication, yet little effort exists that measures the impacts of these popular vehicles of communication. Rarely studied is the role …

Focusing On Equity In Regional Plans, Kristine M. Williams

TREC Project Briefs

Metropolitan planning organizations (MPOs) have long been required to consider the equity implications of their regional transportation plans and processes.

Breaking Barriers To Bike Share: Insights From Residents Of Traditionally Underserved Neighborhoods, Nathan Mcneil, Jennifer Dill, John Macarthur, Joseph Broach, Steven Howland

TREC Final Reports

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, …

Annual Metro Regional Trail Count And Why Local Extrapolation Factors Matter, Geoff Gibson

PSU Transportation Seminars

Metro, Portland's regional governing agency, conducts annual two-hour counts along its regional trail every September. This upcoming fall (2017) will be the 10th year that the counts have been held, which means we at Metro can finally start seeing noticeable, long-lasting trends in the regional trail network. Perhaps more importantly, we are seeing how these data have directly impacted investments in future trail, bicycle, and pedestrian projects.

This seminar will cover the history of the program, details of how it's conducted and why it's conducted that way, how data are used (including an inside look at future iterations of Metro's …

Webinar: Developing Practical Dynamic Evaluation Methods For Transportation Structures, Charles Riley

TREC Webinar Series

Deteriorating transportation infrastructure is constantly in the news. Government agencies at all levels are pursuing methods to monitor structural health, so that they can prioritize repairs. In Oregon, the Cascadia Subduction Zone megathrust earthquake looms as a significant natural hazard for which our transportation network is ill-prepared. The Oregon Department of Transportation (ODOT) estimates that it will take around $2.6 billion over seven years to repair or replace many of the existing bridges in the state’s network to maintain lifeline routes after a Cascadia event. Funding for the scenarios envisioned by ODOT is not forthcoming, and the project …

Peer-To-Peer Carsharing: Short-Term Effects On Travel Behavior In Portland, Or, Jennifer Dill, Nathan Mcneil, Steven Howland

TREC Final Reports

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 …

Narratives Of Marginalized Cyclists: Understanding Obstacles To Utilitarian Cycling Among Women And Minorities In Portland, Or, Amy Lubitow

TREC Final Reports

Research has demonstrated that everyday or utilitarian forms of cycling are most likely to generate positive population-level health impacts (Garrard et al., 2012), yet significant deterrents to routine cycling remain, particularly for women and minorities. The primary aim of this project was to conduct a qualitative interview study that generated rich, narrative data regarding obstacles to routine or utilitarian cycling for women and minorities who already see biking as a viable form of transit, but who make relatively few bike trips. A secondary aim of the project was to develop a set of specific interventions that have the potential to …

Breaking Barriers To Bike Share: Insights On Equity From A Survey Of Bike Share System Owners And Operators, Steven Howland, Nathan Mcneil, Joseph Broach, Kenneth Rankins, John Macarthur, Jennifer Dill

TREC Final Reports

The number of public bike share systems has been increasing rapidly across the United States over the past five to 10 years. To date, most academic research around bike share in the U.S. has focused on the logistics of planning and operationalizing successful systems. Investigations of system users and impacts on the local community are less common, and studies focused on efforts to engage underserved communities in bike share are rarer still. This report uses a survey of representatives from 56 U.S. bike share systems to better understand and document current approaches toward serving low-income and minority populations. The survey …

Bike-Ped Portal: Development Of An Online Nonmotorized Traffic Count Archive, Krista Nordback, Kristin A. Tufte, Nathan Mcneil, Morgan Harvey, Michelle Watkins

TREC Final Reports

Robust bicycle and pedestrian data on a national scale would serve numerous purposes. Access to a centralized nonmotorized traffic count archive can open the door for innovation through research, design and planning; provide safety researchers with a measure of exposure; provide fundamental performance metrics for planning and funding decisions; and allow policymakers and transportation professionals to better support the public’s desire for livable communities. Numerous jurisdictions have initiated nonmotorized traffic count programs. However, many agencies and policymakers, who need data to support investment decisions, are in locations without a centralized count program. This lack of access to count data may …

Ticket To The Past: A Political History Of The Mexico City Metro, 1958-1969, Maxwell E.P. Ulin

Grand Valley Journal of History

This essay outlines the historic political battle between Mexico's longest serving mayor, Ernesto Uruchurtu, and the nation's president, Gustavo Diaz Ordaz, over the construction of what would become the second largest subway system in the Western Hemisphere, The Mexico City Metro. The conflict, which eventually resulted in Uruchurtu's resignation, was characterized by latent political tensions between the PRI and Mexican middle class that would erupt in 1968 and lead to the ultimate decline of PRI hegemony. I thus argue that the new Metro project did not reflect Mexico's democratic modernization--as its supporters meant it to do--but rather the vestiges of …

Barriers To Biking For Women And Minorities, Amy Lubitow

TREC Project Briefs

The health benefits of bicycling are well understood; numerous studies link increased cycling activity with improved health outcomes. Research suggest that the cycling behavior most likely to generate broad, population-level health benefits is everyday routine cycling—including running errands and taking other short trips. Despite these health benefits and new investment in cycling infrastructure, overall cycling levels in the U.S. lag behind many other nations. Amidst findings of increased ridership, research still finds that women and racial minorities are underrepresented as cyclists in North America.

While quantitative data may reveal estimates of these disparities, little is known about the motivations or …

Funded by the National Institute for Transportation and Communities, this research aims to provide additional guidance to MPOs on how to evaluate distributional equity in regional plans and projects. The report begins with an overview of federal requirements related to equity in transportation planning. We then synthesize contemporary methods for measuring transportation equity and the distributional effects of plans and projects from a review of the literature and MPO plans and studies. The report concludes with exploratory case studies of …

Improving Livability Using Green And Active Modes: A Traffic Stress Level Analysis Of Transit, Bicycle, And Pedestrian Access And Mobility, Maaza C. Mekuria, Bruce Appleyard, Hilary Nixon

Mineta Transportation Institute

Understanding the relative attractiveness of alternatives to driving is vitally important toward lowering driving rates and, by extension, vehicle miles traveled (VMT), traffic congestion, greenhouse gas (GHG) emissions, etc. The relative effectiveness of automobile alternatives (i.e., buses, bicycling, and walking) depends on how well streets are designed to work for these respective modes in terms of safety, comfort and cost, which can sometimes pit their relative effectiveness against each other. In this report, the level of traffic stress (LTS) criteria previously developed by two of the authors was used to determine how the streets functioned for these auto alternative modes. …

Transport Planning In Delft, Netherlands, Jan Nederveen

PSU Transportation Seminars

While the Netherlands is known today for the highest bicycling rates in the world, this movement only began in the 1970s. Transportation policy has been one of the critical keys to reducing automobile trips in the Netherlands.

Visiting scholar Jan Nederveen will present on transportation planning in the compact, densely populated city of Delft. Delft has been a city since 1246, and the historic street pattern is still visible today. The city has grown to 100,000 residents and covers an area of 5 square kilometers. Twenty years ago, the council decided to change the transportation philosophy from a car-oriented system …

Webinar: Economic Impacts From Bicycle And Pedestrian Street Improvements, Jenny H. Liu

TREC Webinar Series

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 …

Urbanism Next: How Technology Is Changing Our City, Nico Larco

PSU Transportation Seminars

Advances in technology such as the advent of autonomous vehicles (AV’s), the rise of E-commerce, and the proliferation of the sharing economy are having profound effects not only on how we live, move, and spend our time in cities, but also increasingly on urban form and development itself. These new technologies are changing the ease of transport, the role of transit, and the places we spend our time. These changes will have profound effects on cities including large shifts in land use, changes in street design, a potential reduction on the need for parking, a shift on where we choose …

Transportation Cost Index: A Comprehensive Performance Measure For Transportation And Land Use Systems And Its Application In Or, Fl, And Ut, Liming Wang, Jenny H. Liu

TREC Final Reports

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 …
