Parking Spaces To People Places, Shawn Canny, Natalie Knowles, Arva Hussain, Ann Le, Megan Doherty, Elizabeth Cox

Master of Urban and Regional Planning Workshop Projects

In partnership with the Portland Bureau of Planning and Sustainability (BPS), we sought to better understand how off-street parking space could accommodate economic activity in East Portland, the city’s most economically and racially diverse neighborhood. We focused on two different neighborhoods based on equity considerations and interest: the Rosewood and the Jade Districts. The goal was to better understand these areas with granularity but also to juxtapose them looking for similarities and differences that could guide our recommendations for using parking spaces and serving the community. This project was exploratory in nature. Our research questions and resulting deliverables were dynamic. …

Webinar: Eliminating Cash Options For Public Transit Fares: Costs, Benefits And Equity Impacts, Aaron Golub

TREC Webinar Series

Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership and the …

Applying An Equity Lens To Automated Payment Solutions For Public Transportation, Aaron Golub, John Macarthur, Anne Brown, Candace Brakewood

TREC Final Reports

Many transit agencies plan to automate their fare collection and limit the use of cash for payment, with the goals of improving boarding and data collection while lowering operating costs. Still, about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone, making it very challenging for these riders to ride. In light of these potential challenges, this project was developed by a group of transit agencies and consultants interested in the barriers faced by riders, and what …

Webinar: Rethinking Streets During Covid, Clare Haley, John Larson-Friend, Marc Schlossberg, Aliza Whalen

TREC Webinar Series

Re-allocating space on streets to accommodate new uses – particularly for walking, biking, and being – is not new. However, COVID-era needs have accelerated the process that many communities use to make such street transitions. Many communities quickly understood that the street is actually a public place and a public good that serves broader public needs more urgent than the free flow or the storage of private vehicles. This seminar describes a new case study book that captures some of these quick changes to city streets in response to societal needs during COVID, with two open questions: 1. What changes …

The Impact Of Ride Hail Services On The Accessibility Of Nonprofit Services, Dyana P. Mason, Miranda Menard

TREC Final Reports

Nonprofit organizations are responsible for providing a significant level of human services across the United States, often in collaboration with government agencies. In this work, they address some of the most pressing social issues in society – including homelessness, poverty, health care and education. While many of these organizations consider location and accessibility crucial to supporting their clients – often locating services near bus or train stops, for example – little is known about the impact of new technologies, including ride hail services like Lyft and Uber, on nonprofit accessibility. These technologies, which are re-shaping transportation in both urban and …

Short-Term And Long-Term Effects Of New Light Rail Transit Service On Transit Ridership And Traffic Congestion At Two Geographical Levels, Huajie Yang

Dissertations and Theses

This dissertation quantitatively examines the effect of new Light Rail Transit (LRT) services on transit ridership and traffic congestion over time at two different geographical levels: at the corridor level, this study conducts case studies of two LRT lines in the Portland, Oregon region; at the regional level, this study uses a synthetic control method to construct a "synthetic" control Urbanized Area (UA) that closely approximates the counterfactual transit ridership and traffic congestion scenario in the absence of light rail project in three UAs across America. The results of the corridor-level study suggest that both LRT lines increased transit ridership …

Bi-Objective Optimization For Battery Electric Bus Deployment Considering Cost And Environmental Equity, Xiaoyue Cathy Liu, Yirong Zhou, Ran Wei, Aaron Golub, Devin Macarthur

TREC Final Reports

Public transit, compared with passenger cars, can effectively help conserve energy, reduce air pollution, and optimize flow on roadways. In recent years, Battery Electric Bus (BEB) is receiving an increasing amount of attention from the transit vehicle industry and transit agencies due to recent advances in battery technologies and the direct environmental benefits it can offer (e.g., zero emissions, less noise). However, limited efforts have been attempted on the effective deployment planning of the BEB system due to the unique spatiotemporal features associated with the system itself (e.g., driving range, bus scheduling). In this project, we developed an innovative spatiotemporal …

Webinar: Land Use And Transportation Policies For A Sustainable Future, Liming Wang

TREC Webinar Series

Even though there are tremendous uncertainties in the timing and evolution path of the Autonomous Vehicles (AV) technology, it may become a likely reality within most MPOs' long-range regional transportation plan horizon of twenty years. Yet a recent survey of the largest MPOs in the US indicates only one of them "even mentions driverless, automated, or autonomous vehicles in its most recent RTP". One of the uncertainties in assessing the impacts of AV is their direction: on one hand, self-driving cars could increase VMT by increasing roadway capacity, lowering costs of travel; on the other, they may reduce VMT by …

Webinar: Transportation Benefits Of Polycentric Urban Form, Reid Ewing, Sadegh Sabouri

TREC Webinar Series

A “polycentric” region consists of a network of compact developments connected with each other through high-quality transportation options. Rather than continuing the expanse of low-density development radiating from an urban core, investments can be concentrated on central nodes and transit connections. This development pattern is very popular in Europe and is linked to significant benefits. This presentation is aimed at exploring the academic literature and empirical evidence surrounding polycentric development, analyzing more than 120 regional transportation plans to see how they promote polycentric development, defining types of centers in a hierarchy of centers, quantifying the transportation benefits of polycentric development, …

Peddlers In Means Of Public Transportation In Egypt A Discussion Of Policy Options/ الباعة المتجولين في وسائل النقل العام في مصر: نقاش حول بدائل السياسات, Dina Ahmed Ali, Shatha El Sherif, Zainab Mahmoud Taha

Papers, Posters, and Presentations

The Metro and railway stations play crucial roles in Greater Cairo. Most working-class residents use the Metro and trains as the main transport means to reach their workplace. The Metro carries around 4 million passengers daily, whereas the railways take around 1.4 million passengers per day (Saif Eldien, 2019).

This policy paper is tackling the issue of the informal transportation peddlers namely in the Metro (subway) and railway stations. The authors dealt with this kind of informal peddlers as an occupational segment of the society that contributes to the national economy rather than groups of people who are distorting the …

Difference In Travel Behavior Between Immigrants In The U.S. And U.S. Born Residents: The Immigrant Effect For Car-Sharing, Ride-Sharing, And Bike-Sharing Services, Sangwan Lee, Michael J. Smart, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

Understanding immigrants’ travel behavior is important to transportation planners and policymakers working to implement better transportation planning and public policies to serve those needs. The recent changes to the transportation system, specifically, the recent emergence of shared mobility services, such as car‐sharing, ride‐ sharing, and bike‐sharing, may have resulted in changes in how immigrants travel. Thus, we explored two research questions: (1) whether immigrants in the U.S. are more likely to rely on the three newly emerging transportation modes than US‐born persons, and (2) whether the assimilation theory can be applied to the modes. To answer these questions, we used …

Winning The Fight For Better Bus Service, Steven Higashide

PSU Transportation Seminars

The "right to the city" depends on the right to access the city, and U.S. regions are marked by profoundly unequal access. One of the clearest manifestations of this is the state of U.S. bus transit. Bus service is simple to improve and has vast potential to better people's lives, but has been constrained by the racist planning and politics that shape every American city.

How can we fulfill the promise of better buses and create abundant transit networks that expand access to opportunity? In this seminar, Higashide unpacks the elements of effective bus service – and cites examples from …

Racial Disparities In Traffic Enforcement, Mike Dolan Fliss

PSU Transportation Seminars

Law enforcement traffic stops are one of the most common entryways to the US justice system, with significant downstream impacts for both individuals and communities. Group-specific rates are typically based on jurisdiction resident populations; these rates, like many justice-system indicators, demonstrate race-ethnicity disparities. Residential-based rates implicitly assume race-ethnicity groups have equal vehicle access, equal driving volume, and that all driving occurs in resident’s jurisdictions. In contrast, surveys suggest Black non-Hispanic and Hispanic households have less access and drive less than white non-Hispanic households. Models incorporating US Census data and race-ethnicity driving factors from the 2017 National Household Travel Survey showed …

Curating Equitable Transportation, Nikotris Perkins

PSU Transportation Seminars

Getting people and goods from here to there is central to the ways we live, work, and play in the United States. The transportation networks we create as planners, engineers, geologists, contractors, consultants, advocates, and citizens involve a multitude of decisions. These decisions have great impact on who can get where, when and how; often connected to our structures of social power. This seminar connects those dots, questions our ability to make change, and calls participants to be actively involved in a transportation system that is curated for those it targets: everyone.
