System-Level Risk Management Of Transportation Structures And Networks, David Y. Yang

PSU Transportation Seminars

Conventional risk assessment approaches in infrastructure management do not fully capture the system-level impact of structural failure or service disruption. As a result, the priorities of preservation projects may be misidentified, leading to suboptimal maintenance schedules and waste of resources. In this presentation, we will first illustrate why conventional risk assessment is not suitable for transportation structures and networks due to interdependency between assets, and then demonstrate how system-level preservation policies can be devised using novel algorithms adapted from the field of deep reinforcement learning. Results from a series of case studies showcase that the system-level risk management is essential …

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 …

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 …

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 …

Launching The Wasatch Transportation Academy, Nathan Mcneil, Keith Bartholomew, Matthew Ryan

TREC Final Reports

The “Community Transportation Academy” model seeks to break down the barriers for community members to participate in transportation decision-making processes. Since 1991, the Portland Traffic and Transportation Course has held at least one course each year, connecting Portland residents with top planners, engineers, and decision-makers from agencies working on transportation in the region, with the goal of conveying the factors professionals consider, ranging from technical considerations, legal and policy mandates, other tradeoffs, and how the community can engage with and influence decisions. This project sought to implement a transportation academy in the Salt Lake City region inspired by the Portland …

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 …

Why Your City Needs A Car Master Plan, Cathy Tuttle

PSU Transportation Seminars

In 2022, cars are ubiquitous and completely embedded into America’s economy and social fabric. American cities don’t make car plans, but all transportation plans – whether they are for people who walk, bike, take transit, run freight or delivery businesses – are all written in response to cars. Transportation planning is all about cars; supporting cars or constraining cars. How did our cities evolve into places where cars dominate, and where can we go from here? To move to a new paradigm, cities need to acknowledge car dominance and focus on cars with the same rigor they do other modal …

Evaluation Of Oregon’S Food Waste Recovery And Reintegration Policy Adoption Through Civic Capacity, Jenna N. Stathopoulos

Student Research Symposium

The US Food System is complex and multi-layered, containing many areas for improvement. My research focuses specifically on the issue area of food waste. On a global and national scale mitigating food waste can seem too large to manage. Containing complexity across multiple sectors and with extended timelines for improvements, it is indeed a wicked problem, a problem which in its complexity is almost impossible to fully distinguish or address with one (or even multiple) solutions. (Rittel, 1973). However, when we look to local, place-based solutions we can develop more realistic and actionable plans. The state of Oregon is equipped …

Newberg Car Camping Initiative, Katie Carroll, Ryan Haight, Mary Hendricks, Scott Sharba, Anthony Tortorici, Paul Vickers

Master of Urban and Regional Planning Workshop Projects

The Newberg housing market is experiencing the effects of a rapidly growing population on a relatively static housing stock. As competition for a limited supply of housing increases, low- and moderate-income households face the choice of absorbing rising housing costs or being priced out of their homes. This pressure has shown to result in increased rates of housing instability and houselessness in comparable communities across the state. Concerns around housing affordability prompted the Newberg City Council to adopt a 5-Year Housing Work Program in 2020. The 5-Year Housing Work Program consists of 49 housing-related directives intended to address a variety …
