"Naturally Occurring" Or "Until Market Speculation Starts": Investigating The Precarity Of Affordable Rental Housing And The Potential For Displacement Along Planned Transit Lines, Lisa K. Bates Nov 2017

"Naturally Occurring" Or "Until Market Speculation Starts": Investigating The Precarity Of Affordable Rental Housing And The Potential For Displacement Along Planned Transit Lines, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

New transit infrastructure is a double-edged sword for low-income renters: one the one hand, increased mobility supports access to jobs and critical services; but if transit-oriented development fails to include and preserve affordable housing, they may be pushed out by rising rents. The question of whether public investments spur gentrification and displacement have created intense controversy around planned transit extensions in our region. My research on precarious rental housing illuminates the specific mechanisms of housing displacement and challenges for housing affordability in the single-family/duplex and the large multifamily rental market. The loss of low-cost housing is occurring even without ...

Planning Ahead For Livable Communities Along The Powell-Division Brt: Neighborhood Conditions And Change, Lisa K. Bates, Aaron Golub, Devin Macarthur, Seyoung Sung Jul 2017

Planning Ahead For Livable Communities Along The Powell-Division Brt: Neighborhood Conditions And Change, Lisa K. Bates, Aaron Golub, Devin Macarthur, Seyoung Sung

TREC Final Reports

New transit investments can be a double-edged sword for disadvantaged communities (e.g., those included in environmental justice and Title VI protected classes). Transit investments improve communities’ mobility and access, and may improve health with reduced driving. However, there is also the potential for transit-oriented development (TOD) to spur gentrification and displacement if affordable housing is lost. Understanding transit corridor conditions and change with new infrastructure is important for learning how to mitigate negative effects and support inclusive communities with access to transit for lower-income households. The planning of a new bus rapid transit line along the Powell-Division corridor in ...


Utilizing High Resolution Bus Gps Data To Visualize And Identify Congestion Hot-Spots In Urban Arterials, Nicholas B. Stoll Jan 2016

Utilizing High Resolution Bus Gps Data To Visualize And Identify Congestion Hot-Spots In Urban Arterials, Nicholas B. Stoll

TREC Friday Seminar Series

The research uses high resolution bus data to examine sources of delay on urban arterials. A set of tools were created to help visualize trends in bus behavior and movement, which allowed for larger traffic trends to be visualized along urban corridors and urban streets. By using buses as probes and examining aggregated bus behavior, contoured speed plots were used to understand the behavior of roadways outside the zone of influence of bus stops. These speed plots can be utilized to discover trends and travel patterns with only a few days’ worth of data. Congestion and speed variation can be ...

Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors play a role in its operation and development, and how they, as citizens, play a role in its future. In this sense, there is a goal of broadening and deepening the existing knowledge about the system among the general population. On the other hand, there is an implicit goal of encouraging participation in the system with the understanding that doing ...

Geography Faculty Publications and Presentations

This study investigated potential impacts of climate change on travel disruption resulting from road closures in two urban watersheds in the Portland metropolitan area. We used ensemble climate change scenarios, a hydrologic model, stream channel survey, a hydraulic model, and a travel forecast model to develop an integrated impact assessment method. High-resolution climate change scenarios are based on the combinations of two emission scenarios and eight general circulation models. The Precipitation-Runoff Modeling System was calibrated and validated for the period 1988-2006, and simulated for determining the probability of floods from 2020-2049. We surveyed stream cross sections at five road crossings ...

Green And Economic Fleet Replacement Modeling: Part I, David S. Kim, Miguel Figliozzi, J. David Porter

TREC Final Reports

The purpose of this study was to gain a better understanding of how equipment replacement decisions are supported with data collection and quantitative models at state DOTs, and to determine if models found in the research literature offer any better decision support when applied to realistic fleet usage and cost data. This study also addressed the current state of equipment replacement at state DOTs with respect to using measurable “green” criteria in replacement decisions, and the development of new quantitative replacement models utilizing such criteria. The responses from 25 state DOTs indicates that there is little consistency in the criteria ...

Evaluation Of Transportation Microenvironments Through Assessment Of Cyclysts' Exposure To Traffic-Related Particulate Matter, Linda A. George, Miguel A. Figliozzi, Christopher M. Monsere, Christine M. Kendrick, Alexander Y. Bigazzi, Adam Moore

TREC Final Reports

It is well established that vehicles powered by carbon-based fuels (e.g. gasoline, diesel) have a negative impact on air quality, especially in urban centers. Traditionally, air quality conformity studies analyze the macroenvironmental impact of transportation corridors, as they relate to regional air quality management concerns. Urban residents spend a considerable amount of outdoor time in transportation microenvironments as pedestrians, bicycle commuters, people waiting to use public transport, residents and workers situated along roadways, and commuters within vehicles. An emerging area of research has shown that human health impacts within transport microenvironments can be considerable, but have not been well-characterized ...

Pedestrian Infrastructure Improvements: Effects On Transit Use And Perceptions Of The Pedestrian Environment In Portland's Roseway Neighborhood, James G. Strathman, Kenneth Dueker, Peter Mye, Joyce A. Felton Jul 1999

Pedestrian Infrastructure Improvements: Effects On Transit Use And Perceptions Of The Pedestrian Environment In Portland's Roseway Neighborhood, James G. Strathman, Kenneth Dueker, Peter Mye, Joyce A. Felton

Center for Urban Studies Publications and Reports

Over the past two years the Pedestrian Transportation (PTP) of the City of Portland has been engaged in a project to encourage walking and transit use through targeted infrastructure improvements. These improvements are intended to enhance pedestrian access to transit service by aiding street crossing and providing more amenities at bus stops. Other improvements include landscaping, sidewalks, curb extensions and ramps, and improved street lighting. One of the basic assumptions of this project is that the pedestrian environment is related to transportation choices. This report explores that assumption.
