Safety Impacts of Intersection Sight Distance

Christopher Monsere
Research questions include: How does intersection sight distance (ISD) impact crashes? How can temporal variations in ISD (e.g., foliage) be quantified? Should quality of ISD and the presence of objects to judge depth perception be considered? How do ... Read More

Toward Effective Design Treatments for Right-Turns at Intersections with Bicycle Traffic

Christopher Monsere
The overall goal of the proposed research is to quantify the safety performance of alternative traffic control strategies to mitigate right-turning vehicle-bicycle crashes at intersections in Oregon. ... 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

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

Bus Safety Performance Monitoring and Analysis

James Strathman
This paper analyzes collision and non-collision incidents that occurred on TriMet’s bus system over a near two-year period. The bus route network was decomposed into stop and line haul segments, and a typology of models was estimated from segment l ... Read More

Improved Pedestrian Safety at Signalized Intersections Operating the Flashing Yellow Arrow

David Hurwitz
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

Seismic Hazard Assessment of Oregon Highways

Peter Dusicka
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

Assessment of Statewide Intersection Safety Performance

Christopher Monsere
This report summarizes the results of an analysis of the safety performance of Oregon’s intersections. Following a pilot study, a database of 500 intersections randomly sampled from around the state of Oregon in both urban and rural environments wa ... Read More

Developing a Highway Safety Investigation Manual for the Oregon Department of Transportation

Christopher Monsere
Across the state, region, and nation highway safety investigators have developed a wide variety of tools and techniques for highway safety investigation procedures. Analysis techniques can range from systematic evaluation approaches such as the Orego ... Read More
