Can Ridehailing Deliver Equity? Lessons For New Mobility Planning, Anne Brown

PSU Transportation Seminars

Modes including ridehailing, bikeshare, and e-scooters offer the potential to revolutionize how people travel. But as cities and agencies work to integrate these new services into the existing transportation landscape, the equity implications of these modes remain murky.

This talk presents research on ridehail travel and equity from Los Angeles and compares the equity outcomes of ridehailing to the previous status quo embodied by taxis. The research highlights both the promise of new mobility services and the remaining obstacles to delivering equitable access. Findings yields implications for policies that cities and planners can advance to ensure that new travel modes …

Life-Space Mobility And Aging In Place, Ivis Garcia Zambrana, Alan Kenneth Delatorre, Ja Young Kim, Julianne Reno, Keith Diaz Moore, Jordan Pieper, Jason Wheeler, Nicole Zinnanti, Brenda Jose

TREC Final Reports

Research on older adults explores the notion of “aging in place”—providing older adults the opportunity to continue to occupy familiar surroundings, to live in their own homes and communities. But oftentimes one’s ability to stay or leave, particularly in old age, depends on the built environment. Mobility is the ability to meet the basic needs to access goods, activities, services, and social interactions as they relate to quality of life. Thus, mobility is essential to older adults due to their limited, or gradually reducing, physical and cognitive abilities. In transportation research, mobility is often regarded in terms of travel behavior …

Webinar: Engaging Youth To Choose Car-Free Mobility, Autumn Shafer

TREC Webinar Series

Today’s youth are tomorrow’s riders, bikers, walkers, voters, and transportation planners. As more transit agencies begin to offer free fare passes to public middle and high school students, it is important to have good communication strategy in place to encourage transit usage so they don't miss out on the potential to affect behavior change.

Thus, transit agencies need to develop age-appropriate messaging strategies and tactics that promote youth car-free mobility.

This webinar will present results from a NITC research project that sought to create and evaluate communication messaging that fosters more positive attitudes, intentions, and behaviors related to transit and …

Making The Seemingly Impossible Project Real Through Local Improvement Districts, Andrew H. Aebi

PSU Transportation Seminars

The planning process identifies community needs but often needs the creative use of financial leverage to make those projects a reality on the ground. Timing is important on Local Improvement District (LIDs), and the window of opportunity is often short.

For Portland's Bureau of Transportation, managing the public's desire for streets in good condition with room to walk and bike safely and accommodating freight movement and population growth can be a tall order. Add in the need to work with water, sewer and underground utilities, and things get complicated.

When needs exceed resources, smart strategies can help fill the gap. …

Can Churches Change A Neighborhood? A Census Tract, Multilevel Analysis Of Churches And Neighborhood Change, David E. Kresta

Dissertations and Theses

This study examines the role of local churches in neighborhood change, analyzing the relationship between Christian churches and changes in household median incomes from 1990 to 2010 in the census tract in which each church is located. Based on a nationally representative sample of churches from 2006 and 2012, the study uses hierarchical linear modeling and statistical matching techniques to analyze how key church characteristics such as social service involvement, social capital generation, residential patterns of attendees, and demographic composition are related to changes in neighborhoods. Two primary research questions were addressed: 1) How have patterns of church location changed …

Green Ring Wayfinding Map, Lorena Nascimento, Adam Brunelle, Arlene Amaya

Student Research Symposium

Lents is one of the most diverse neighborhoods in Portland, with a higher percentage of Latinos and Asians than the average city demographics. The neighbors are either long-term homeowners, people displaced from North Portland due to the gentrification, and new residents seeking economic development areas with an affordable price. The Green Ring Wayfinding Map is a community place-making project that improves neighborhood safety, accessibility, and enjoyment through conversations and collaboration across Lents diversity and geography. After three years of focus groups and surveys with the Lents residents, a Green Ring Wayfinding Map is being created to praise the values, branding, …

That Bike Is Too Heavy: Merging Bicycling Physics, Human Physiology And Travel Behavior, Alexander Y. Bigazzi

PSU Transportation Seminars

Are the Biketown bikes too heavy? Does better gear motivate people to cycle more? How much faster will someone go on an e-bike?

Although urban cycling is widely known as physically active transportation, the actual physics of cycling have been given little attention in transportation engineering and planning. In contrast, the field of sports science has developed detailed data and models of road bicycle performance, but only for sport and racing cyclists.

What can we learn about utilitarian cycling by integrating knowledge of the physical attributes of bicycles and cyclists?

This seminar examines the ways in which bicycle physics, and …

Revitalization In Philadelphia, 1940-1970: Rebuilding A City But Straining Race Relations, Abigail E. Millender

Young Historians Conference

This paper examines government and privately sponsored revitalization projects in inner city and Center City Philadelphia from 1940-1970. These projects—including the construction of rail lines connecting Center City to the suburbs, changes to the National Housing Act, and the revitalization of Society Hill—were meant to bring investment back into the city after the economy had declined from de-industrialization. These projects successfully rebuilt the inner city’s economy, however, they ultimately hurt African-American and minority populations and encouraged segregation. The revitalization of Center City over other parts of inner city and the perpetuation of subprime loans displaced many African Americans, lowered home …

The E-Bike Potential: Estimating The Effect Of E-Bikes On Person Miles Travelled And Greenhouse Gas Emissions, Michael Mcqueen, John Macarthur, Christopher Cherry

TREC Final Reports

Many cities have goals for reducing automotive VMT in order to reduce tailpipe emissions and to reduce congestion. Conventional cycling is a good solution, though its uptake has slowed in recent years in several cities, despite the implementation of greenways, bikeshare, and bike lines (Anderson and McLeod 2017). Electric bicycles (e-bikes) could be an effective new part of the solution to combat mode shift stagnation. The e-bike is a recently introduced mode of travel that is rapidly gaining in popularity throughout the United States.

The e-bike can offer a cheaper alternative to car travel (Popovich et al. 2014) and can …

How E-Bike Incentive Programs Are Used To Expand The Market, Michael Mcqueen, John Macarthur, Christopher Cherry

TREC Final Reports

The electric bicycle (e-bike) is a low emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security (Blondel, Mispelon, and Ferguson 2011). In a recent study conducted by Portland State University, e-bikes have been found to enable more people to ride a bicycle for longer distances despite physical limitations, difficult terrain, and the presence of cargo (MacArthur et al. 2018). However, overall e-bike adoption in the United States remains limited due in part to high purchase cost (Dill and Rose 2012; Popovich et al. …

An Agent-Based Evacuation Model To Improve Safety In The Cascadia Subduction Zone, Haizhong Wang

PSU Transportation Seminars

This seminar will present ongoing research into how integrated social, natural, and engineered systems can improve life safety under threat of multi-hazards. The targeted scenario is a magnitude 9.0 earthquake and tsunami from the Cascadia Subduction Zone, threatening communities along 1,000 miles of the US Pacific Northwest coastline.

Since the mid-1980’s scientific evidence has underscored the possibility of such an extreme event, and it has taken at least another decade or more before public attitudes and policy have begun to adapt to this new hazard. Life safety is a pressing issue for the near-field CSZ tsunami hazard for several reasons. …

Gentrification And Student Achievement: A Quantitative Analysis Of Student Performance On Standardized Tests In Portland's Gentrifying Neighborhoods, Justin Joseph Ward

Dissertations and Theses

Across the United States one would be hard pressed to find an urban center that has been unaffected by the phenomenon known as gentrification. From substantial economic growth to the displacement of long-term residents, the benefits and criticisms of the process of gentrification are wide ranging and extend over a thorough body of literature. Commonly associated with increasing levels of education and higher resident incomes, gentrification should be a boon to struggling public schools that are continually plagued by generational poverty. Unfortunately, the continued widening of the education gap and increasing racial segregation in our public schools suggest that any …

Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub

TREC Project Briefs

Since 1994, every Federal agency has a mandate to develop a strategy for identifying and addressing disproportionately high and adverse human health or environmental effects on low income populations and minority populations. In transportation planning this means including those communities’ voices in the planning process, and evaluating the social impacts early on.

A new report from the Federal Highway Administration (FHWA), prepared by Portland State University and ICF International, provides an in-depth analysis of national demographic trends and a synthesis of best long-range planning practices borne out of five case studies

Access To Opportunity Project: Final Report, Shawn Flanigan, Emily Lieb, Lisa K. Bates, Raphael Bostic, Sheryl V. Whitney

Urban Studies and Planning Faculty Publications and Presentations

This project’s goal is to lift up promising approaches, suggest new strategies and encourage honest conversations that result in public policy solutions to income and racial segregation and poverty. The overarching question that motivates this work is:

• What are effective policies and strategies that promote access to high-opportunity amenities for low-income families?

As a first step, the researchers surveyed efforts on the ground in the metropolitan areas encompassing Seattle, Washington; Portland, Oregon; and San Diego, California, to determine whether there were any candidates for deeper study. We selected these three metropolitan areas for several reasons. First, prior interaction revealed that …
