Behavior of Drilled Shafts with High-Strength Reinforcement and Casing
(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 ... -
Benchmarking and Safety Assessment for Modified Lateral Spreading Design Procedure using Three-Dimensional Nonlinear Finite Element Analysis
(2017)Liquefaction-induced lateral spreading is a critical design consideration for many bridges in high-seismicity regions of the Pacific Northwest, with broad impacts on safety for the general public. The bridge design procedures ... -
Bicycle Route Choice: GPS Data Collection and Travel Model
(2014)Bicycle use is being promoted for a variety of social benefits. Because of the benefits associated with bicycling, jurisdictions across the central Puget Sound region and the nation have been investing in improvements to ... -
Bicycle Safety Analysis: Crowdsourcing Bicycle Travel Data to Estimate Risk Exposure and Create Safety Performance Functions
(2016)Around 700 bicycle fatalities happen every year, and the number has steadily increased since 2009. At the same time Seattle, Wash., and Portland, Ore., are promoting cycling as a healthy transportation mode, so bicycle ... -
Biking the Goods - How North American Cities Can Prepare for and Promote Large-Scale Adoption of Cargo e-Bikes
(2023-10-01)This paper aims to inform urban planners about what cargo e-bikes are, how they have been successfully deployed in North America to replace ICE vehicles and identify actionable strategies cities can take to encourage their ... -
Blockchain-based Smart Contracts for Transportation Infrastructure Project Funding
(2023)The USDOT Strategic Plan highlights the importance of improving the mobility of people and goods through its focus on infrastructure. However, a significant portion of the transportation infrastructure in the United States–up ... -
Bride Structural Inspections using Bridge Information Modeling (BrIM) and Unmanned Aerial Vehicles (UAVs)
(2019-12)Bridge inspection is a critical task needed to monitor bridge quality and serviceability. In the U.S., 40 percent of bridges are more than 50 years old, while most bridges are typically designed for a lifespan of 50 years. ... -
Changing Retail Business Models and the Impact on CO2 Emissions from Transport: E-Commerce Deliveries in Urban and Rural Areas
(2015)While researchers have found relationships between passenger vehicle travel and smart growth development patterns, similar relationships have not been extensively studied between urban form and goods movement trip making ... -
Characterization of Frictional Interference in Closely-Spaced Reinforcement in MSE Walls
(2014)This research addresses one of several knowledge gaps in the understanding of tall MSE wall behavior: prediction of reinforcement loads impacted by frictional interference of closely-spaced reinforcements associated with ... -
Combining Crowdsourcing and Machine Learning to Collect Sidewalk Accessibility Data at Scale
(2021)We are developing new data collection approaches that use a combination of remote crowdsourcing, machine learning, and online map imagery. Our newest effort, called Project Sidewalk, enables online crowdworkers to remotely ... -
Commuter Mobility versus Work-zone Safety: An Empirical Study using Data Mining of Anonymous User Generated Trip Information
(2019)The two primary considerations for highway work-zones are its effect on commuter mobility and worker safety which are often spoken of together. However, it must be noted that they conflict with each other. This research ... -
Competitive State-of-the-Art Structural Engineering
(2015)The University of Alaska Fairbanks (UAF) steel bridge team had an exceptional year, largely due to the chemistry of the team and to financial backing at all levels. The team won the regional competition and placed ninth ... -
Confounding Factors of Commercial Motor Vehicles in Safety Critical Events
(2018)Recent quasi-experimental commercial motor vehicle (CMV) driver hours-of-service (HOS) studies published through the Federal Motor Carrier Safety Administration (FMCSA) in 2011 readily identified consistent increases in ... -
Connected Vehicle Safety Applications using V2X under Consideration of Bicycles, Pedestrians, and Persons with Special Needs
(2021)In the context of connected vehicles, the focus of safety applications has mainly been on accident avoidance of motor vehicles, and little attention has been given to the safety of other traffic participants like bicycles, ... -
A Connected Vehicle-Based Adaptive Navigation Algorithm
(2019)Connected vehicle (CV) technology leads to a system in which vehicles can communicate with other vehicles, transportation infrastructure, and other devices with communication capabilities. With increases in data availability, ... -
