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

Principal Investigator: Christopher Monsere

Co-Investigators: 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

Principal Investigator: 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

Principal Investigator: 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

Developing Framework for Incorporating Mitigation Effectiveness into the TPR Process

Principal Investigator: Kelly Clifton

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

Principal Investigator: 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

Seismic Retrofit Benefit Considering Statewide Transportation Assessment

Principal Investigator: 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

Integrated Multimodal Transportation, Air Quality, and Livability Corridor Study Phase II

Principal Investigator: Miguel Andres Figliozzi

Co-Investigators: Christopher Monsere , Linda George

The Sydney Coordinated Adaptive Traffic System (SCATS) is used to mitigate traffic congestion along urban arterial corridors. Although there has been research on SCATS’ performance, this report combines three different areas of research about SCATS ... Read More

Improved Pedestrian Safety at Signalized Intersections Operating the Flashing Yellow Arrow

Principal Investigator: David Hurwitz

Co-Investigator: Christopher Monsere

In some jurisdictions, protected left-turn phasing has been replaced with the flashing yellow arrow (FYA) for protected/permissive left turns (PPLTs) to reduce delay. However, it is important to have a thorough understanding of the conflict between p ... Read More

Multimodal Data at Signalized Intersections: Strategies for Archiving Existing and New Data Streams to Support Operations and Planning

Principal Investigator: Christopher Monsere

Co-Investigator: Kristin Tufte

There is a growing interest in arterial system management due to the increasing amount of travel on arterials and a growing emphasis on multimodal transportation. The benefits of archiving arterial-related data are numerous. This research report desc ... Read More

Transit Bus Fleet Management and Optimization Models Addressing New Engine Technologies and Emissions Constraints

Principal Investigator: Miguel Andres Figliozzi

Co-Investigator: Ashley Haire

Due to recent budget and fiscal constraints, it is ever more imperative for transit agencies to manage their fleets in an optimal way. Fleet data have consistently shown that bus operational and maintenance (O&M) per-mile costs increase as buses age. ... Read More

A Study of Headway Maintenance for Bus Routes: Causes and Effects of "Bus Bunching" in Extensive and Congested Service Areas

Principal Investigator: Miguel Andres Figliozzi

Co-Investigators: Gerardo Lafferriere , Wu-chi Feng

A healthy and efficient public transit system is indispensable to reduce congestion, emissions, energy consumption, and car dependency in urban areas. The objective of this research is to 1) develop methods to evaluate and visualize bus service relia ... Read More

Seismic Hazard Assessment of Oregon Highways

Principal Investigator: Peter Dusicka

Co-Investigator: John Gliebe

This research project developed a seismic risk assessment model along the major truck routes in Oregon. The study had adopted federally developed software tools called Risk for Earthquake Damage to Roadway Systems (REDARS2) and HAZUS-MH. The model wa ... Read More
