Statistical Inference For Multimodal Travel Time Reliability, Avinash Unnikrishnan, Miguel Figliozzi, Subhash C. Kochar

TREC Final Reports

Travel time reliability is a key metric of interest to practitioners and researchers because it affects travel choice and the economic competitiveness of urban areas. This research focuses on three travel time reliability metrics – buffer index, modified buffer index, and the relative width of travel time distributions. The key novel contributions of this research include using the multivariate delta method to prove that the sampling distributions of the three travel time reliability metrics are asymptotically normal. The asymptotic standard error for the three reliability metrics is derived. The asymptotic normality and the standard error result are used to arrive …

50 Years And Counting: Why Environmental Preservation Is Embedded In Oregon Culture, Carl Abbott

Urban Studies and Planning Faculty Publications and Presentations

In the years following World War II, suburban growth began consuming Willamette Valley farmland. Increasingly affluent families were snapping up vacation properties with mountain and ocean views. Oregonians in the latter half of the 1960s responded with conferences, reports and finger-wagging at the bad example of California. In 1969, the legislature acted with Senate Bill 10. The legislation established land-use regulation as a state concern, requiring local governments to develop land-use plans in line with 10 statewide goals. The intention was good, but the measure lacked teeth for monitoring and enforcement. McCall promised to fix the problems when he ran …

Impacts Of City-Level Parking Cash-Out And Commuter Benefits Ordinances, Gabriella Abou-Zeid, Allen Greenberg

PSU Transportation Seminars

For many workers, the decision to drive to work is an economically rational one that minimizes their commute costs. The vast majority of employers offer free workplace parking, with few in comparison offering benefits for transit, walking, biking, or other means of commuting. In effect, employers are incentivizing a behavior that increases roadway congestion, reduces physical activity, and increases emissions. Moreover, since lower-income households are less likely to own and have access to a private vehicle than moderate and higher-income households, free parking is a financial benefit that many lower-income employees cannot access.

Community Transportation Academy: Course Curriculum And Implementation Handbook, Nathan Mcneil, Keith Bartholomew

TREC Final Reports

A Community Transportation Academy (CTA) is a course that harnesses the knowledge, technical expertise and passions of practicing transportation professionals in a city to immerse a cohort of interested and dedicated community members in transportation issues over a two to three month curriculum.

The CTA curriculum was developed by drawing from the Portland Traffic and Transportation (PTT or Portland CTA) course, along with the Wasatch Transportation Academy (WTA or Wasatch CTA, which was inspired by the Portland course). Planning academy courses in cities around the country are also good models to look to for how to structure and operate such …

Equity And Exclusion Issues In Cashless Fare Payment Systems For Public Transportation, Aaron Golub, Anne Brown, Candace Brakewood, John Macarthur, Sangwan Lee, Abubakr Ziedan

Urban Studies and Planning Faculty Publications and Presentations

Many transit agencies in the United States plan to automate their fare collection and limit–or even eliminate–the use of cash fares, with the goals of expediting boarding, collecting data, and lowering costs. Yet about 10% of US adults lack a bank account or credit card, and many rely on restrictive cellphone data plans or do not have access to the internet or a smartphone. These riders will find it difficult to access transit in the future. This paper examines transit users’ experiences with fare technologies using a survey of riders in three cities. Our analysis reveals which riders are most …

Reconceiving The Relationship Between The Built Environment And Walking Behavior: Examining The Samples, Scales, And Methods In Travel Behavior Research, Jaime Pablo Orrego-Oñate

Dissertations and Theses

This dissertation aims to formulate a mechanism for the relationship between the urban form and walking choice that can be consistent across contexts. The motivation is the lack of concordant results in the magnitude of the environmental influence on walking choice in urban areas found in the literature. The dissertation identifies a series of limitations in previous research that could cause mixed results in the magnitudes of the association. This research elaborates an approach to overcome these limitations by proposing a mechanism of the activity density over walking modal share by controlling for trip distance distribution. The aim is an …

An Analysis Of The Strengths And Weaknesses Of The Tulsa Remote Program, As An Effective Economic Development Strategy, Kristen J. Padilla

Dissertations and Theses

Cities do not exist in a vacuum. They are in constant competition for talented, educated individuals and growing, innovative businesses -even if that competition is not explicit or specific. Traditionally cities have been left with two economic development paths to help diversify their economies: attract talent but without jobs, or attract business but without a strong talent pool. However, due to technological advancements, exacerbated by the pandemic, a new and growing workforce that can work from anywhere has emerged, remote workers. This talent pool shifts traditional economic development attraction strategies from city to industry to city to talent.

Many remote …

Examining Emergency Citizen Response To The Covid-19 Pandemic: Emergent Groups Addressing Food Insecurity In Portland, Oregon, Aliza Ruth Tuttle

Dissertations and Theses

Emergency response agencies commonly focus on how hard infrastructure will interact with extreme climatic and geologic events: bridges during an earthquake and buildings following a tornado, for example. Peoples' actual experience of these extreme events vary, however, based on socially constructed consequences of natural hazard events and their interaction with a depleted or robust social safety net.

Previous research shows people living with depleted social safety nets and who experience a natural hazard event are likely to help where they see disaster. Individuals consistently form groups, called emergent groups, to organize their efforts. This research explored emergent groups that formed …

Intermediate Effect Of The Covid-19 Pandemic On Prices Of Housing Near Light Rail Transit: A Case Study Of The Portland Metropolitan Area, Sangwan Lee, Liming Wang

Urban Studies and Planning Faculty Publications and Presentations

This study explored the dynamics of a residential property value premium for proximity to a light rail transit (LRT) station in the intermediate term (roughly two years) since the pandemic. We applied a longitudinal quasi-experimental design using repeat sales data from the Portland Metropolitan Area, Oregon. Our results indicate that the effect of the pandemic on prices of housing near LRT stations differs between single-family and multi-family markets. Since the pandemic outbreak, there has been no statically significant difference in the price appreciation between singlefamily (SF) housing within an LRT service area and otherwise similar SF homes; however, for multi-family …

Public History Is Now, Sarah E. Dougher

Amplify: A Journal of Writing-as-Activism

A walking tour of downtown Portland in August 2021 raises questions for the writer about the purpose of “memory activism,” its relation to writing-as-activism. Drawing on critiques of urbanist Jane Jacobs and interrogating the concept of “reckoning,” the essay explores ways in which the streetscape and people there can deliver meaning and pose questions about systemic racism and unsheltered existence.

Mobility For The People: Evaluating Equity Requirements In Shared Micromobility Programs, Anne Brown, Amanda Howell, Hana Creger

TREC Final Reports

Technology-enabled shared micromobility services have expanded mobility for some travelers, but significant barriers to use limit their uptake among certain groups. To address these barriers, cities and professional transportation organizations have undertaken two distinct efforts to operationalize equity in shared micromobility services: 1) drafted equity frameworks in an attempt to clearly define equity within the transportation context and to provide guidelines for what cities should consider when designing equity-based mobility programs; and 2) some cities have attempted to ameliorate access disparities by establishing new requirements for shared micromobility programs. Both equity frameworks and program requirements mark important steps to operationalizing …

Transit And Active Transportation Use For Non-Commute Travel Among Portland Transit-Oriented Development Residents, Jennifer L. Dill, Nathan W. Mcneil

Urban Studies and Planning Faculty Publications and Presentations

Transit-oriented development (TOD) seeks to promote non-single occupancy vehicle travel by placing dense residential and mixed-use buildings near high-capacity, high-frequency transit. Most research to date on the impact of TODs on travel behavior has focused on commute trips; however, many trips are for non-work purposes, and a sizable portion of the population does not commute to work. This study utilizes a set of surveys, conducted between 2005 and 2019 in the Portland OR region to assess factors associated with whether or not, and how often, TOD residents walk, bike, or take transit for home-based non-work trips. Findings show that about …
