TREC Final Reports
Compact development can result in many benefits for communities and residents. Areas can connect compact developments through high-quality transportation options, creating a network of centers, or a “polycentric” region. This development pattern is very popular in Europe and is linked to significant benefits. Salt Lake County has organically developed several small centers, and with the right strategies could continue to fuel this kind of growth. The metropolitan planning organization (MPO) for the region, the Wasatch Front Regional Council, has been planning for polycentric development since the Wasatch Choice for 2040 Vision was released in 2010. Our research is aimed at …
Regional Transportation Goals: Reducing Sprawl Through Interconnected Centers, Reid Ewing
Regional Transportation Goals: Reducing Sprawl Through Interconnected Centers, Reid Ewing
TREC Project Briefs
A “polycentric” region is a network of compact developments (centers) that are connected with each other through high-quality transportation options. As the antidote to sprawling suburbs, compact centers can encourage all the things that sprawl discourages: public health, environmental sustainability, social cohesion, and economic diversity. But how can metropolitan planning organizations ensure that their regional plans will actually meet these goals? Polycentric development has been advocated by urban and transportation planners for more than a decade. However, effective practice must be backed by solid research, and to date there has been little or no research that quantifies the transportation benefits …
The Role Of Bus Stop Features In Facilitating Accessibility, Keith Bartholomew, Ja Young Kim, Divya Chandrasekhar, Reid Ewing, Arlie Adkins, Samuel Jensen
The Role Of Bus Stop Features In Facilitating Accessibility, Keith Bartholomew, Ja Young Kim, Divya Chandrasekhar, Reid Ewing, Arlie Adkins, Samuel Jensen
TREC Final Reports
Although transit decision-makers and riders generally favor improving bus stops by adding shelters, benches, and similar features, it is unclear the impact such features have on transit demand and there has been little research that measures these impacts. This study examines the link between stop improvements and changes in stop-level boardings on scheduled-service buses and in ADA paratransit demand in the Salt Lake City, UT, metropolitan area between 2014 and 2017. The study also investigates current bus stop improvement practices of leading transit agencies nationwide. The study uses a number of quantitative and qualitative techniques, including propensity score matching, propensity …
Urban Transportation System Flood Vulnerability Assessment With Special Reference To Low Income And Minority Neighborhoods, Courtney Crosson, Daoqin Tong, Yinan Zhang
Urban Transportation System Flood Vulnerability Assessment With Special Reference To Low Income And Minority Neighborhoods, Courtney Crosson, Daoqin Tong, Yinan Zhang
TREC Final Reports
A flood vulnerability assessment of the City of Tucson, Arizona’s transportation systems was conducted with special reference to low-income and minority neighborhoods. Short-term flooding from extreme storm events pose a serious challenge to transportation system reliability and emergency response in cities across the United States. This problem, which is anticipated to grow over the next century due to climate change, is often hardest on vulnerable populations, including low-income and minority neighborhoods. Our work aimed to advance national research methods for assessing multi-modal transportation degradation due to flooding. We identified priority locations for Tucson to make transportation improvement investments for the …
The Potential Of Green Infrastructure In Mitigating Flood Impacts On The Mobility Of Low Income And Minority Neighborhoods, Courtney Crosson, Yinan Zhang, Daoqin Tong
The Potential Of Green Infrastructure In Mitigating Flood Impacts On The Mobility Of Low Income And Minority Neighborhoods, Courtney Crosson, Yinan Zhang, Daoqin Tong
TREC Project Briefs
Short-term flooding from extreme storm events poses a serious transportation challenge in U.S. cities. This problem—which is anticipated to grow over the next century with our global climate crisis—is often hardest on vulnerable populations, including low-income and minority neighborhoods. This project advances national research methods for assessing flood vulnerability and prioritizing transportation improvement investments to ensure that no community is left stranded when the next flood occurs.

Webinar: Findings From 15 Years Of Travel Surveys At Portland Area Transit-Oriented Developments (Tods), Jennifer Dill, Nathan Mcneil
TREC Webinar Series
Since 2005, Portland State University has periodically surveyed occupants of recently developed higher-density and mixed-use projects near transit, often referred to as Transit-Oriented Developments (TODs). The general objectives of the surveys were to better understand actual transit use, among other factors, of residents in these buildings. Between 2005 and 2018, the research team surveyed residents of nearly 50 TODs. With funding from Metro and the National Institute for Transportation and Communities, the research team carried out a two-pronged study drawing on this wealth of data. First, we explore geographic differences within the Portland region in terms of travel behavior and …
Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John Macarthur, Aaron Golub
Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John Macarthur, Aaron Golub
PSU Transportation Seminars
As transit agencies modernize their fare payment systems, opportunities to pay with cash are reduced. This speeds boarding and lowers the cost of operations while also creating new sources of ridership data. Arguably, service is improved for riders as well as payment systems could work across modes, creating a more seamless and simplified experience. Still, about 15% of adults in the United States are without a bank account or credit card account and many rely on restrictive cell-phone data plans or don’t have access to a smartphone. These shares are even higher for public transit users. These un- and under-banked …
Revisiting Tods: How Subsequent Development Affects The Travel Behavior Of Residents In Existing Transit-Oriented Developments, Nathan Mcneil, Jennifer Dill
Revisiting Tods: How Subsequent Development Affects The Travel Behavior Of Residents In Existing Transit-Oriented Developments, Nathan Mcneil, Jennifer Dill
TREC Final Reports
Portland State University has worked with the Portland Metro regional government periodically since 2005 to survey occupants of buildings for which developers had received funding from Metro’s Transit-Oriented Development (TOD) Program. This research extends upon the prior TOD surveys in Portland by revisiting a set of developments with a second wave of surveys to understand how the travel behavior of TOD residents may change over time, and what factors influence change in travel patterns. The second-wave surveys, coming 8-13 years after the baseline surveys, include five TODs in the west-side Portland suburbs of Hillsboro and Beaverton, two TODs in East …

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 …
