Mixed Use Safety on Rural Facilities in the Pacific Northwest – year 3 (2014-2015)

PI: Nathan Belz (UAF)
Co-Investigators: Billy Connor (UAF), Byron Bluehorse (UAF), Kevin Chang (UI), Ahmed Abdel-Rahim (UI), Mostafa Hegazi (UI)
Dates: 01/15/2015 – 06/15/2016

In the United States, formalized facilities and roadway crossings for non-traditional and non-motorized modes do not exist which jeopardizes the safety of these users in many cases. These factors create a pervasive and systemic nationwide safety issue. This research will address the issues associated with providing safe accommodation, limiting the improper use of public rights-of-way, and maintaining mobility, and provide future guidelines for design, education, and enforcement for mixed-use rural facilities. The goal of this project is to: improve safety and minimize the dangers for all transportation mode types while traveling in mixed-use environments on rural facilities through the development and use of engineering and education safety measures.

Unmanned Aircraft System Assessments of Landslide Safety for Transportation Corridors – year 3 (2014-2015)

PI: Keith Cunningham (UAF)
Co-Investigators: Michael Olsen (OSU), Joseph Wartman (UW)
Dates: 01/15/2015 – 06/15/2016

The proposed research addresses Pacific Northwest Transportation Consortium (PACTRANS) research priority of using new data-driven technologies to improve the safety of transportation systems in the Northwest United States. Landslides pose significant threats to the safety of motorists throughout the mountainous terrain of the Pacific Northwest The research will advance landslide safety assessment for transportation corridors by capitalizing on recent advances in unmanned aircraft systems (UAS) and new low-cost Structure from Motion (SfM) photogrammetry techniques. The resulting improved hazard assessment techniques will facilitate cost-effective evaluation of landslide safety across the broadly distributed transportation networks of the Pacific Northwest.

Bicycle Safety Analysis: Crowdsourcing Bicycle Travel Data to Estimate Risk Exposure and Create Safety Performance Functions – year 3 (2014-2015)

PI: Haizhong Wang (OSU)
Co-Investigators: Yinhai Wang (UW), Michael Lowry (UI)
Dates: 01/15/2015 – 06/15/2016

Engineers and planners face challenges like insufficient data and lacking of proper tools when conducting safety analysis for bicyclists. This project will create tools, guidelines, and repeatable processes that engineers and planners can use to analyze crowdsourced bicycle data, calculate bicycle exposure to dangerous situations, and create and analyze safety performance functions for bicyclists.

Behavior of Drilled Shafts with High-Strength Reinforcement and Casing – year 2 (2013-14)

PI: Armin W. Stuedlein (OSU)
Co-Investigators: Pedro Arduino (UW)
Dates: 07/01/2013 – 6/30/2015

Drilled shafts provide significant geotechnical resistance for support of highway bridges, and are used throughout the States of Oregon and Washington to meet their structural foundation requirements. Due to changes in construction methods and poor near-surface soils, the use of permanent steel casing for drilled shaft installation has increased. However, geotechnical design models for axial and lateral resistance of drilled shafts are largely based on soil-concrete interfaces, not soil-steel interfaces associated with large diameter steel casing.

Performance-Measure Based Asset Management Tool for Rural Freight Mobility in the Pacific Northwest – year 2 (2013-14)

PI: Jeremy Sage (WSU)
Co-Investigators: Ahmed Abdel-Rahim (UI), Kenneth Casavant (WSU)
Dates: 07/01/2013 – 6/30/2015

Moving Ahead for Progress in the 21st Century (MAP-21) establishes national objectives to increase productivity and economic efficiency of the nation’s freight infrastructure. The recent passage of MAP-21 has placed an emphasis on integrating asset and performance management tools to help transportation agencies better manage the critical transportation infrastructure. Infrastructure performance management expands the more traditional definition of Asset Management to include measurement and reporting of how those assets achieve their targeted operational objectives.
