Speed Management And Speed Reduction In Portland, Or, Jason C. Anderson, Clay Veka

PSU Transportation Seminars

In 2015, the Portland City Council unanimously passed a resolution committing Portland to Vision Zero, the goal to eliminate traffic deaths and serious injuries. An underpinning of Vision Zero is that streets are managed for safe speeds. This presentation will summarize Portland's speed management process, how it relates to achieving Vision Zero, and present two case studies in which speed limits were reduced: (1) a 25 mi/h to 20 mi/h reduction on residential streets and (2) various reductions on arterials and collectors. Reduction sites in which additional treatments were implemented, such as speed humps and fixed speed safety cameras, will …

In Favor Of Bringing Game Theory Into Urban Studies And Planning Curriculum: Reintroducing An Underused Method For The Next Generation Of Urban Scholars, Brian Mcdonald Gardner

Dissertations and Theses

By looking at some historical examples of Urban Studies literature and theory (and a detailed dive into Neil Smith's "Toward a theory of gentrification…") this thesis makes the case that Game Theory has valid insights to add to the foundation of Urban Studies and Planning and should be included in Masters and Doctorate level curriculums. As a discipline Game Theory has revolutionized multiple other fields, and can be used both mathematically and/or non-mathematically. It is postulated below that the inclusion of Game Theory would help scholars and practitioners arrive at better outcomes. This case is made by reviewing various areas …

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 …

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 …

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

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 …

Shared electric scooters (e-scooters) are fast becoming a mobility option in cities across the United States. This new micromobility mode has the potential to replace car usage for certain trips, which stands to have a positive impact on public health and sustainability goals. However, many aspects of this emerging mode are not well understood.This webinar explores the findings of three NITC studies examining transportation mode choices, safety, and public health outcomes of electric scooters.

A Walk In The Park: A Spatial Analysis Of Crime And Portland Parks, Cheyenne Pamela Hodgen

Dissertations and Theses

This thesis presents two individual research papers that examine the relationship between greenspaces and crime in Portland, Oregon. The two papers use an adapted street network buffer to better measure crime concentration around discrete locations. This methodological development allows for an improved measure of crime concentration around discrete locations.

The first contribution, explores the relationship between different greenspace types and crime, breaking down different crime types into discrete categories. The results of this study suggest that overall, Portland greenspaces do not experience a concentration of crime, however, different patterns emerge as greenspace and crime types are disaggregated. Only one greenspace …

Regional Decision-Making In Oregon’S Area Commissions On Transportation, Cole P. Grisham

Hatfield Graduate Journal of Public Affairs

Long after other areas of Oregon had already done so, the local agencies in the Portland region served by the Oregon Department of Transportation decided to form a regional Area Commission on Transportation. Why they decided to do so and what caused local agencies to delay forming one until long after other regions was not immediately clear. In this article, I examine the policy documents around the formation of the Region 1 ACT and how its policy history represents wider historical trends on regional transportation decision making nationally. To do so, I describe Oregon’s regional policy making structure followed by …

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 …

Webinar: Exploring Data Fusion Techniques To Derive Bicycle Volumes On A Network, Sirisha Kothuri, Joe Broach, Kate Hyun

TREC Webinar Series

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes. Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has …

Webinar: Is Transit-Oriented Development Affordable For Low And Moderate Income Households?, Reid Ewing, Justyna Kaniewska

TREC Webinar Series

Transportation and land use planning, as a field, is shifting away from segregated uses connected by highways and streets to more compact, mixed-use developments connected by high-quality transit. This new paradigm has brought special attention to transit-oriented developments (TOD), which are sometimes touted as being among the most affordable, efficient places to live. But how affordable are they, and who has the power to effect change? This study examines housing costs for households living in TODs.
