Transportation And Gentrification: Impacts On Low-Income Black Households In Portland, Steven Howland May 2021

Transportation And Gentrification: Impacts On Low-Income Black Households In Portland, Steven Howland

TREC Friday Seminar Series

Portland’s Black population has been heavily impacted by gentrification in the historic Albina community. Nearly half of Portland’s Black population lives in the area east of 82nd Ave, known as East Portland. This has had substantial impacts on both Black households that can continue living in Albina and those living in East Portland. The suburban-esque built environment of East Portland makes it difficult to get around and reach basic necessities. Those living in Albina have taken on exorbitant rents. Both groups suffer from a geographic divide that has made it difficult to rely on family and friends for ...

Winning The Fight For Better Bus Service, Steven Higashide Dec 2020

Winning The Fight For Better Bus Service, Steven Higashide

TREC Friday Seminar Series

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 ...


Racial Disparities In Traffic Enforcement, Mike Dolan Fliss Nov 2020

Racial Disparities In Traffic Enforcement, Mike Dolan Fliss

TREC Friday Seminar Series

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 ...


Curating Equitable Transportation, Nikotris Perkins Nov 2020

Curating Equitable Transportation, Nikotris Perkins

TREC Friday Seminar Series

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.


At The Intersection Of Safety + Race + Transportation, Charlene Mcgee Nov 2020

At The Intersection Of Safety + Race + Transportation, Charlene Mcgee

TREC Friday Seminar Series

Transportation policies at the local, regional, state and national levels have a direct impact on urban land use and development patterns. Transportation intersects with multiple areas including public health, education, climate change, physical activity, health outcomes, build environment, violence, safety, social cohesion and the wellness of communities. For the health outcomes influenced by transportation, disparities exist by race, ethnicity, and socioeconomic status in Multnomah County. Disproportionate exposure to injury, air pollution, and noise contributes to inequitable burdens of injuries and chronic disease among race and ethnic groups. This is exacerbated by lack of access to safe places for active transportation ...


Case Studies Of Travel Demand Analysis On Transport Disadvantaged Communities, Tierra Bills Oct 2020

Case Studies Of Travel Demand Analysis On Transport Disadvantaged Communities, Tierra Bills

TREC Friday Seminar Series

Travel Demand Models are the backbone of decision-making for public transportation infrastructure investment. Yet, critiques of these models with respect to their usefulness and performance for transport disadvantage communities are rare in the academic literature. These disadvantage communities may include (but are not limited to) low income travelers, transit dependents, un/underemployed, and the elderly. With the objective of promoting travel demand models that are better equipped for assessing transportation impacts for disadvantaged communities, this presentation highlights lessons learned from two case studies of applying travel demand analysis to understand the transportation accessibility of low income, elderly, and transit dependent ...

Biking While Black: How Planning Contributes To Unjust Policing, Jesus Barajas Oct 2020

Biking While Black: How Planning Contributes To Unjust Policing, Jesus Barajas

TREC Friday Seminar Series

Neighborhoods of color tend to be the most dangerous places for cyclists and other road users, a result in part of historic disinvestment and failure to provide basic infrastructure. Safety efforts to reduce crashes, like Vision Zero, have called for both increased investment, a qualified benefit for disenfranchised communities, and increased traffic enforcement, a response that is likely to place people of color in even greater harm based on extensively documented police injustice.

  • For more about the problems of policy and planning around 'bicycling while black,' check out a Sept 9, 2020 blog post by Jesus Barajas.

Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John Macarthur, Aaron Golub May 2020

Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John Macarthur, Aaron Golub

TREC Friday Seminar Series

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 ...

Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong Apr 2020

Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong

TREC Friday Seminar Series

Prior studies show that transit-oriented developments (TODs) increase property values and raise property tax revenue. Property owners reap economic benefit from TODs and public officials use it as evidence to justify the high cost of rail transit. However, renters, who rely on transit more than homeowners, may have to pay higher rent to live in TODs. The location affordability index at the neighborhood level suggests that renters can also benefit from TOD by saving money on transportation costs. Recent studies at the individual level, however, found little evidence that living in TODs reduces transportation expenditure. Using rental data scraped from ...

Bus-Bike Designs For The Division Transit Project, Derek Abe, Jesse Stemmier

TREC Friday Seminar Series

This seminar is brought to you by the Oregon chapter of the Association of Pedestrian and Bicycle Professionals (APBP), with support from TREC at Portland State.

Transit stops and stations are a confluence of complementary and competing activities - pedestrians accessing businesses, passengers boarding and alighting, and bicyclists zipping through to their destinations. People are moving in different directions, at different speeds, and need to be able to navigate this space safely and comfortably. A common point of conflict is the bus/bicycle interaction when a transit stop is adjacent to a bike lane. Designs for integrating pedestrian and bicycle facilities ...

The Safe System Approach: Considerations For Developing A Multi-Layered System, Offer Grembek Oct 2019

The Safe System Approach: Considerations For Developing A Multi-Layered System, Offer Grembek

TREC Friday Seminar Series

While the overarching objective of the transportation system is to provide mobility, it should be developed and operated under the framework of a safe system with the aspirational goal to establish a system on which no road user can be severely or fatally injured. To accomplish such a safe system, it is necessary to effectively harness all the core protective opportunities provided by the system. This includes the street design and operations, user behavior, vehicle design, protection systems, and EMS. The common thread across these layers is speed. This is directly driven by the quadratic relationship between velocity and kinetic ...
