Emerging Technologies And Cities: Assessing The Impacts Of New Mobility On Cities, Rebecca Lewis, Rebecca Steckler

TREC Final Reports

Advances in emerging technologies – such as autonomous vehicles (AVs), e-commerce, and the sharing economy – are having profound effects not only on how we live, move, and spend our time in cities, but also on urban form and development itself. These new technologies are changing how people and goods move around a city and are beginning to have substantial effects on land use, street design, parking, and housing. These changes will have significant implications for city governance, revenues, and budgets.

In partnership with the cities of Gresham and Eugene (the Cities), this project assessed the challenges and opportunities presented …

From Confrontation To Partnership: City Regulation Of Micromobility, William Henderson

PSU Transportation Seminars

It has been more than two years since shared scooters first appeared in Santa Monica, California and more than four years since the first dockless bikeshare bikes appeared in China. As shared micromobility has experimented in its deployment and operations across the globe, cities have also been experimenting with ways to regulate and manage this phenomenon in a way that best achieves public outcomes. But how do we best protect individual rights' while still protecting the right-of-way? This seminar will discuss experiences from cities with micromobility programs and considerations for agency staff and elected officials when launching and overseeing a …

Fast Track: Allowing Bikes To Participate In A Smart-Transportation System, Stephen Fickas, Marc Schlossberg

TREC Final Reports

This project focuses on a mode of transportation that is currently left out of V2X (vehicle-to-everything) conversations: bicycling. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to give bicyclists the same technology appearing on modern vehicles: Green Light Optimized Speed Advisory (GLOSA). GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a “green wave” (i.e., not being forced to stop as they travel through the corridor). This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists on a …

TREC Final Reports

This project builds an open-source, socio-transportation analytic (STAT) toolbox for public transit system planning in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies in evaluating and enhancing the performance of public transit systems. This toolbox is novel and essential to transit agencies in two aspects. First, it enables the integration, analysis and visualization of two major, new open transportation data, social media and GTFS data, to support transit decision-making. Second, it allows transit agencies to evaluate service network efficiency and access equity of transit systems in a cohesive manner, and identify areas …

Bicycle Planning Gis Tool, Joseph Broach

TREC Final Reports

Although currently only about one percent of US trips are done by bicycle, there is significant geographic variation. Differences across communities, along with much higher cycling rates observed in other places around the world, indicates large potential bicycling demand for daily travel in the US. In response, many communities are developing and implementing bicycle master plans that include a range of bikeway infrastructure aimed at making riding more appealing, including separated paths, protected (or separated) bike lanes, striped bike lanes, bicycle boulevards, sharrows, route signage, and intersection crossing aids. Given limited resources, planners and engineers need tools to estimate the …

Planning In Gateway And Natural Amenity Region Communities: Understanding The Unique Challenges Associated With Transportation, Mobility, And Livability, Danya Rumore, Philip Stoker, Zacharia Levine, Lindsey Romaniello

TREC Final Reports

Communities outside of major public lands and other natural amenities throughout the western United States face a variety of transportation and planning-related concerns associated with rapid growth and increases in tourism. Surprisingly, while the unique transportation and planning-related challenges of these western gateway and amenity region (GNAR) communities have, to some extent, been documented in recreation and tourism research, these concerns have largely been overlooked in planning scholarship. To begin to address this gap, this report presents key descriptive findings from a study aimed at examining the unique transportation, mobility, and access to opportunity-related challenges being experienced by GNAR communities …

Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub

TREC Project Briefs

Since 1994, every Federal agency has a mandate to develop a strategy for identifying and addressing disproportionately high and adverse human health or environmental effects on low income populations and minority populations. In transportation planning this means including those communities’ voices in the planning process, and evaluating the social impacts early on.

A new report from the Federal Highway Administration (FHWA), prepared by Portland State University and ICF International, provides an in-depth analysis of national demographic trends and a synthesis of best long-range planning practices borne out of five case studies

Based on the state of practice review, the report also highlights …

Modeling Changes In Public Transit And Private-For-Hire Usage When Implementing A Spatial Tax, Ty Lazarchik

REU Final Reports

Private-for-Hire (PfH) transportation options, such as Uber, Lyft, and taxicabs, are consistently growing in popularity. With this expanded utilization, cities are struggling to maintain usage of their public transit systems. While PfH transportation has been heavily researched, there is a need to further study how its effects on transit usage may be minimized. In this paper, previous work in traffic modeling and analysis of transit and PfH differences are expanded to develop an agent-based decision model in order to simulate and analyze the effectiveness of implementing a location-based tax in and around the city center of Portland, Oregon. The results …

Barriers To “New Mobility”: A Community-Informed Approach To Smart Cities Technology, Aaron Golub, Vivian Satterfield

PSU Transportation Seminars

There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This presentation will describe the results of an assessment of these equity impacts in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research.

Portland, Oregon’s proposal for the U.S. Department of Transportation’s Smart City Challenge, “Ubiquitous Mobility for Portland,” focuses on developing mobility solutions that would serve traditionally underserved populations (low-income, communities of color, and residents with mobility challenges). This study found that by lowering …

Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

This study investigates the impacts of positive and negative externalities of highways and light rail on commercial property values in Phoenix, Arizona. We hypothesize that the positive externality (i.e., accessibility) of highway and light rail accrues at exits and stations, whereas nodes and links of highways and light rail emanate negative effects. Positive and negative effects decay with increasing distance and are captured by multiple distance bands. Hypotheses are tested using a spatial error regression model. Results show that commercial property values are positively and significantly associated with the accessibility benefits of transport nodes. The distance-band coefficients form a typical …

Active And Public Transportation Connectivity Between North Temple Tod And Jordan Park River Trail, Ivis Garcia Zambrana, Christie Oostema

The project seeks to capitalize on existing community assets—several TOD stations and a regional bike and pedestrian trail system—by studying how these can be linked. The overarching goal of this project is to increase scholarship on networking safe routes that can encourage public and active transportation choices and thus, encourage a healthier lifestyle and advance sustainability. By expanding pedestrian, bicycle and transit connections to green space and offering the most potential for TOD, this proposal clearly demonstrates the greatest priorities of NITC. Moreover, nationwide, communities like Salt Lake’s West Side are in greater need of sustainable transportation choices that foster …

Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo

TREC Webinar Series

Parking is a serious issue in many urban areas, especially those experiencing rapid population growth. To address this problem, some cities have implemented demand-responsive pricing programs, where parking prices vary depending on the occupancy rate in a previous period. Yet, few empirical studies have rigorously evaluated these programs. In this study, we investigate the impacts of SFpark, a demand-responsive pricing parking program in San Francisco that began in 2011. We observe effects on three important aspects of urban transportation: parking availability, transit bus ridership and congestion. The timing of this program is plausibly exogenous to factors that affect these outcomes …

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 …

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.

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, …

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 …

Addressing Data Challenges For Bicycle Crash Analysis, Eleni Christofa

PSU Transportation Seminars

Although an increasing number of separated bicycle facilities have been appearing across the US over the last few years, the majority of bicyclists are still traveling on roadways shared with motorized vehicles.

As a result, bicycles are essentially double exposed to safety risk, due to their interactions with both motorized vehicles and other bicycles. In addition to this double exposure, data challenges–such as a lack of continuous counts and bicycle crash data—complicate the assessment of bicycle safety further.

This research presents a bicycle crash analysis framework for estimating bicycle crash rates accounting for both bicycle and motorized vehicle exposure as …

Impact Of Bike Facilities On Residential Property Prices, Wei Shi

PSU Transportation Seminars

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 …

Trip And Parking Generation At Transit-Oriented Developments, Reid Ewing, Guang Tian, Torrey Lyons, David Proffitt, Preston Stinger, Rachel Weinberger, Ben Kaufman, Kevin Shivley

TREC Final Reports

The decision of how best to allocate land around transit stations is a debated topic, with transit officials often opting for park-and-ride lots over active uses such as multifamily housing, office, and retail organized into transit-oriented developments (TODs). In practice, guidelines for providing parking and mitigating vehicle trips come mainly from the Institute of Transportation Engineers (ITE) Trip Generation Manual and the ITE Parking Generation Manual. However, both manuals have well-known shortcomings. The goal of this study is to determine how many fewer vehicle trips are generated at TODs, and how much less parking is required at TODs, than ITE …

Realistic Or Utopian? Coordinating Transit And Land Use To Achieve Equitable Transit-Oriented Development, Ian Carlton

PSU Transportation Seminars

Equitable transit-oriented development (E-TOD)—the prioritization of social equity as an outcome of TOD implementation—has become a U.S. DOT policy stance, an objective of many other government bodies, and part of many NGOs' missions. But is it feasible to coordinate transit and land use in ways that allow us to achieve these goals, or is this a classic example of a wicked problem?

This talk will use Portland as a case study to explore some of the internal contradictions inherent in E-TOD goals, the systemic challenges that must be considered, and glimmers of hope for delivering E-TOD. Transportation and land use …
