Unmanned Aircraft System Assessments of Landslide Safety for Transportation Corridors
PI: Keith Cunningham (UAF), kwcunningham@alaska.edu
Co-Investigators: Michael Olsen (OSU), Joseph Wartman (UW)
Dates: 01/16/2015 – 06/15/2016
Status: Completed
UTC Project Sheet
Final Technical Report
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.

Status: Completed
UTC Project Sheet
Final Technical Report
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
PI: Armin W. Stuedlein (OSU), armin.stuedlein@oregonstate.edu
Co-Investigators: Pedro Arduino (UW)
Dates: 07/01/2013 – 6/30/2015
Final Project Report: PacTrans-24-OSU-Stuedlein
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
PI: Jeremy Sage (WSU), jlsage@wsu.edu
Co-Investigators: Ahmed Abdel-Rahim (UI), Kenneth Casavant (WSU)
Dates: 07/01/2013 – 6/30/2015
Final Project Report: PacTrans-40-WSU-Sage
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.

A Platform for Proactive Risk-based Slope Asset Management Phase II
PI: Keith Cunningham (UAF), kwcunningham@alaska.edu
Co-Investigators: Michael J. Olsen (OSU), Joseph Wartman (UW)
Dates: 11/1/2013 – 7/31/2015
Final Project Report: PacTrans-42-UAF-Cunningham
Unstable slopes, including coherent landslides, rock falls, and debris flows, present significant risk to safety and regional commerce. This risk is a long-term concern that highway managers contend with on an on-going basis. The widespread spatial and temporal distribution of these landslides poses a number of challenges when deciding when, where, and how to allocate funds for mitigation efforts to maintain these assets. This challenge is compounded by the high level of effort currently required to survey, inspect and sample slopes for the purpose of condition assessment as part of an asset management program.
