Access to Opportunities: Redefining Planning Methods and Measures for Disadvantaged Populations

Arlie Adkins
Stephen Mattingly
This project will be made up of two separate studies that together will investigate areas where transportation planning and engineering can better serve disadvantaged and underserved communities. An interdisciplinary team of planning and public healt ... Read More

Understanding Factors Affecting Arterial Reliability Performance Metrics

Avinash Unnikrishnan
Sirisha Kothuri
With worsening congestion, travel time reliability is increasingly becoming as critical as average travel times in affecting travel choices. This research project will first study the data requirements for existing travel time reliability metrics bei ... Read More

Data and Methodological Issues in Assessing Multimodal Transportation Impacts for Urban Development

Kristina Currans
In 1976, the Institute of Transportation Engineers (ITE) compiled their first Handbook of guidelines and methods for evaluating development-level transportation impacts, specifically vehicular impacts (Institute of Transportation Engineers 1976). De ... Read More

Improving Walkability Through Control Strategies at Signalized Intersections

Sirisha Kothuri
Christopher Monsere , Edward Smaglik
The goal of signal timing at an intersection should be to separate conflicting movements in time, maximizing safety and efficiency for all users. In many jurisdictions, however, signal timing objectives have traditionally focused on allowing vehicle ... Read More

Exploiting New Data Sources to Quantify Arterial Congestion and Performance Measures at a Regional Scale

Miguel Figliozzi
Robert Bertini
Most urban vehicle miles traveled take place along arterials and collector streets. Arterials and collector streets are also essential to provide accessibility and provide mobility for public transportation fleets; these roadways constitute the back ... Read More

Impact of Cascadia Subduction Zone Earthquake on the Seismic Evaluation Criteria of Bridges

Peter Dusicka
ODOT project page: http://www.oregon.gov/ODOT/TD/TP_RES/docs/stage1/2014stageone/14_087_Seismic_Evaluation_Criteria.pdf Under our current seismic design code, bridge designers ... Read More

Modeling and Analyzing the Impact of Advanced Technologies on Livability and Multimodal Transportation Performance Measures in Arterial Corridors

Miguel Figliozzi
Christopher Monsere
Transit service reliability is important to both passengers and transit agencies. Slow and unreliable transit service may increase transit user costs in the short term and reduce transit mode share and ridership in the long term, which in turn may le ... Read More

Lessons from the Green Lanes: Evaluating Protected Bike Lanes in the U.S.

Christopher Monsere
Jennifer Dill , Kelly Clifton , Nathan McNeil
This report presents finding from research evaluating U.S. protected bicycle lanes (cycle tracks) in terms of their use, perception, benefits, and impacts. This research examines protected bicycle lanes in five cities: Austin, TX; Chicago, IL; Portla ... Read More

Lightweight Buckling Restrained Brace Prototype Evaluation

Peter Dusicka
Buckling restrained brace (BRB) is a structural component that has been developed to provide known and repeatable strength in both tension and compression. Over the last couple ofdecades, BRBs have seen broad adoption in buildings in areas ofmoderate ... Read More

Evaluation of Bike Boxes at Signalized Intersections: Phase 2

Christopher Monsere
Analyses of motor vehicle and police-reported crash data reveal that nearly 68 percent of bicycle crashes in Portland, Oregon occur at intersections (PDOT, 2004) which is consistent with national trends (Hunter et al., 1996). Hunter et al. (1996) ... Read More

Development, Deployment and Assessment of a New Paradigm for Transportation Professionals and University Students: a Collaboration of the Region X Transportation Consortium

Christopher Monsere
Traditionally, engineering coursework has been delivered in a lecture-based format with accompanying exercises assigned for time outside of class. The activity-based approach to learning aims to keep students engaged in and responsible for their own ... Read More

Prioritization for Seismic Retrofit with Statewide Transportation Assessment

Peter Dusicka
The bulk of the bridge inventory in Oregon was built prior to the current understanding of bridge response and prior to current understanding of the expected earthquake demands. While some bridges are being replaced due to other deficiencies, majorit ... Read More
