Oregon Population Estimates and Reports
The Tri-City Service District (TCSD) and Clackamas County Service District #1 (CCSD #1), both of Clackamas County, requested that the Population Research Center (PRC) at Portland State University produce long-term population forecasts for each of the two sewer service districts. In addition, CCSD#1 requested that forecasts also be developed to include the entire city of Damascus to account for possible future annexation into its district; and the city of Milwaukie, as CCSD#1 leases services to Milwaukie. The forecast horizon extends 30 years from 2010 to 2040, and projections are produced in 5-year intervals. For the 2010-2015 interval, forecast numbers for …
Our Cities And The City: Incompatible Classics?, Carl Abbott
Our Cities And The City: Incompatible Classics?, Carl Abbott
Urban Studies and Planning Faculty Publications and Presentations
At the end of the 1930s, Americans interested in the fates and futures of their cities had the opportunity to consider two new efforts to summarize urban problems and propose solutions. The first was Our Cities: Their Role in the National Economy, published in 1937 under the auspices of the National Resources Board. The second was The City, a film sponsored by the American Institute of Planners for showing at the New York world's fair in 1939. The report and the film arose out of different analytical traditions, the first from the approach that embedded urban planning within a larger …

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 …

Design Of A Dynamic Activity Travel Modeling System For Metro, John Gliebe
Design Of A Dynamic Activity Travel Modeling System For Metro, John Gliebe
Urban Studies and Planning Faculty Publications and Presentations
Trip-based models are no longer adequate for some of the more complex questions. They fail to account for time of day sensitivity, dynamic congestion effects, variable pricing and tolls, and the reliability of both highways and transit. Existing activity/tour-based models lack the enhanced temporal element provided by a more dynamic, activity-based microsimulation. DASH is the next-generation model being developed by the Metro Research Center.

Value Of Travel-Time Reliability: Commuters’ Route-Choice Behavior In The Twin Cities, Carlos Carrion-Madera, David Levinson, Kathleen Harder, Miguel A. Figliozzi
Value Of Travel-Time Reliability: Commuters’ Route-Choice Behavior In The Twin Cities, Carlos Carrion-Madera, David Levinson, Kathleen Harder, Miguel A. Figliozzi
TREC Final Reports
Travel-time variability is a noteworthy factor in network performance. It measures the temporal uncertainty experienced by users in their movement between any two nodes in a network. The importance of the time variance depends on the penalties incurred by the users. In road networks, travelers consider the existence of this journey uncertainty in their selection of routes. This choice process takes into account travel-time variability and other characteristics of the travelers and the road network. In this complex behavioral response, a feasible decision is spawned based on not only the amalgamation of attributes, but also on the experience travelers incurred …

Green And Economic Fleet Replacement Modeling: Part I, David S. Kim, Miguel A. 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 …
Combined Seismic Plus Live Load Analysis Of Highway Bridges, Michael H. Scott, Minjie Zhu
Combined Seismic Plus Live Load Analysis Of Highway Bridges, Michael H. Scott, Minjie Zhu
TREC Final Reports
The combination of seismic and vehicle live loadings on bridges is an important design consideration. There are well-established design provisions for how the individual loadings affect bridge response: structural components that carry vertical live loads are designed to remain well within the linear-elastic range while lateral load carrying components are designed to yield under large seismic excitations. The weight of the bridge superstructure is taken in to account as dead load in structural analysis for seismic loads; however, the effects of additional mass and damping of live loads on the bridge deck are neglected. To improve the design of highway …

Who’S Home? – A Look At Households And Housing In Oregon, Risa S. Proehl
Publications, Reports and Presentations
Where we live and who we live with have a huge influence on our everyday lives. Do we live alone or share a home with family or friends? Do we own or rent? How affordable is our housing when compared to our income and how is the value of our house changing? All of these issues shape how we live our lives.
Similarly, housing and households influence the character of neighborhoods and communities. The share of households with children and seniors, the share of households that rent or own, the size of households, and the cost and supply of housing …

Evaluation Of Safe Routes To School Programs: Qualitative And Quantitative Analysis Of Parental Decision-Making, Lynn Weigand, Noreen Mcdonald
TREC Final Reports
In the United States, walking to school declined from 42% of 5-18 year olds in 1969 to 16% in 20011. The US Department of Transportation has responded to this dramatic decrease by funding the Safe Routes to School program for $612 million in SAFETEA-LU. The program’s funding emphasize infrastructure improvements such as completing sidewalks and adding crosswalks by requiring between 70% and 90% of funding be allocated toward infrastructure. However, recent research shows that 2 of 3 children who currently are driven to school, but live close enough to walk, do so because it is more convenient for parents. Currently, …

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. As …

A Pivot Point? Economic Slow-Down Affects Oregon’S Migration Flow, Jason R. Jurjevich
Publications, Reports and Presentations
The combination of three components: fertility, mortality, and migration, collectively lead to population change. Fertility and mortality events in recent history, including escalated fertility levels associated with the ‘baby boom cohort’ and spikes in mortality linked to the Spanish Flu of 1918 for example, have produced demonstrative demographic effects. However, both the unpredictability and ability of migration to produce virtually immediate impacts, often enduring for decades across social, cultural, demographic, and economic landscapes, has long captured the attention of scholars and public policy makers alike. Over the past several decades here in Oregon, migration has undoubtedly shaped the state socially …
