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. As …

Safety Evaluation Of Curve Warning Speed Signs, Karen K. Dixon, Raul Eduardo Avelar, Ida Schalkwyk

TREC Final Reports

This report presents a review of a research effort to evaluate the safety implications of advisory speeds at horizontal curve locations on Oregon rural two-lane highways. The primary goals of this research effort were to characterize driving operations at rural two-lane highway curve locations where advisory speed signs were present, and to determine to what extent these signs play a role in enhancing safety.

Factors For Improved Fish Passage Waterway Construction, David N. Sillars, Hamid Moradkhani, Nicholas Tymvios, Trevor D. Smith

TREC Final Reports

Streambeds are important fish passageways in Oregon; they provide for the necessary habitats and spawning cycles of a healthy fish population. Oregon state law requires that hydraulic structures located in water properly provide fish passage. Increasingly stringent state and federal regulations apply to these fish passageways, and designers must become more cognizant of conditions over a range of flows to accommodate fish movement and avoid expensive structural failure of these passageways. Fish passage structures are built when roads cross streambeds and may include culverts, or bridges. When these structures are built, the streambeds are re-created using a technique called “roughened …

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 …

Oregonians Report Broad Support For Policies That Could Reduce Prison Population, Jody Sundt

Criminal Justice Policy Research Institute Research Briefs

Correctional spending is one of the largest and fastest growing parts of the Oregon budget, making it a target for increased scrutiny. According to a 2011 Legislative Fiscal Office report, the Department of Correction’s (DOC) budget represented close to 9% of the combined General and Lottery Funds in the 2009- 2011 biennium. Since 1993-1995, correctional spending increased almost threefold from close to $400 million to $1.4 billion. Moreover, the DOC’s share of the state budget almost doubled since the mid-1980s. In the context of declining revenue forecasts and increased demand for public services, state agencies are under pressure to reduce …

Overlooked Density: Re-Thinking Transportation Options In Suburbia, Phase Ii, Nico Larco

TREC Final Reports

Comprising over 9 million units in this country, suburban multifamily housing is a widespread and overlooked example of density located within walking distance to commercial development in suburbia. This report focuses on resident demographics, attitudes, and perceptions as they relate to mode choice in 14 suburban multifamily sites in Eugene, Oregon. Through site analysis and resident surveys, our study shows that site design and connectivity is a significant predictor of resident mode choice. Residents of more-connected developments walk and bike to their local commercial area for more than 40% of their trips, nearly twice the rate of residents of less-connected …

The Federal Highway Administration (FHWA) has put a high priority on the use of existing dynamic message signs (DMS) to provide travel time estimates to the public. The Oregon Department of Transportation (ODOT) has three DMS in the Portland metropolitan area configured to display travel time information. In the near future, ODOT would like to make travel time estimates available on additional DMS, over the Internet on tripcheck.com and via 511. Travel time estimates are valuable to the traveling public; however, the estimates must be accurate to be useful. The purpose of this study is to extend prior travel time …

Exploratory Methods For Truck Re-Identification In A Statewide Network Based On Axle Weight And Axle Spacing Data To Enhance Freight Metrics, Christopher M. Monsere, Mecit Cetin, Andrew Nichols

TREC Final Reports

The main objective of this project is to evaluate the feasibility of re-identifying commercial trucks based on vehicle-attribute data automatically collected by sensors installed at traffic data collection stations. To support this work, archived data from weigh-in-motion (WIM) stations in Oregon are used for developing, calibrating, and testing vehicle re-identification algorithms. The vehicle re-identification methods developed in this research consist of two main stages. In the first stage, each vehicle from the downstream station is matched to the most “similar” upstream vehicle by using a Bayesian model. In the second stage, several methods are introduced to screen out those vehicles …

Information Disclosure And Environmental Performance, Mark Stephan

Systems Science Friday Noon Seminar Series

Scholars and policymakers increasingly argue that information disclosure programs such as the Toxics Release Inventory (TRI) should be used to supplement conventional environmental regulation. Yet we lack a clear understanding of how such programs work as well as the empirical data to confirm their success in achieving environmental quality objectives. To better understand the impacts of environmental information disclosure on corporate decision making, this paper develops an analytic framework drawn from theories of risk perception and communication, individual and corporate decision making, and social capital. I examine the importance of the TRI for facility level behavior through an analysis of …

Urban Studies and Planning Faculty Publications and Presentations

Two innovative bicycle facilities installed in late summer and early fall 2009 in downtown Portland by the City of Portland Bureau of Transportation (PBOT) were evaluated to understand how they are functioning on multiple levels. All of these facilities involved removing a motor vehicle lane by restriping to provide additional roadway space to bicyclists. The facilities include:

• A cycle track (a seven-foot bike lane separated from motor vehicle traffic by a row of parked cars and a painted three-foot pedestrian buffer), on SW Broadway from SW Clay to SW Jackson through the Portland State University campus, and
• A couplet of …

No More Freeways: Urban Land Use-Transportation Dynamics Without Freeway Capacity Expansion, Lei Zhang, We Xu

TREC Final Reports

Observations of the various limitations of freeway capacity expansion have led to a provocative planning and policy question – What if we completely stop building additional freeway capacity. From a theoretical perspective, as a freeway transportation network matures, there exists a saturation point beyond which any additional freeway capacity would only be counterproductive from a welfare point of view, and worsen the existing urban transportation problems. Traditional benefit/cost analysis of individual freeway capacity expansion projects often ignores long-term induced demand and land use changes and does not represent a systems approach to this important theoretical issue. From a practical perspective, …
