THEORIZING THE INTERNAL SOCIAL SUSTAINABILITY OF SANITATION ORGANIZATIONS
(Journal of Construction Engineering and Management, 15-09)Onsite household sanitation technologies such as septic tanks or latrines serve a large percentage of the world’s population. Unfortunately, they experience high failure rates after construction, with resulting environmental ... -
Technology Development to Explore the Relationship Between Oral Health and the Oral Microbial Community
(2006)The human oral cavity contains a complex microbial community that, until recently, has not been well characterized. Studies using molecular tools have begun to enumerate and quantify the species residing in various niches ... -
Developing a Performance Measurement Approach to Benefit/Cost Freight Project Prioritization
(2014)Future reauthorizations of the federal transportation bill will require a comprehensive and quantitative analysis of the freight benefits of proposed freight system projects. To prioritize public investments in freight ... -
A Platform for Proactive Risk-Based Slope Asset Management - Phase I
(2014)Unstable slopes, including landslides, rock falls, and debris flows, present significant risk to safety and regional commerce, and present a chronic concern for highway managers. Due to the widespread spatial and temporal ... -
Performance Monitoring for Safe and Livable Communities: Fusing Data, to Improve Arterial Operations for All Users
(2014)Measuring or analyzing transportation system performance occupies a large transportation professional’s time. So, improving performance measurement methods in terms of accuracy and cost are important contributions. This ... -
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 ... -
New Strategies for Maintaining Post-Seismic Operations of Lifeline Corridors
(2014)This project furthered the development of three strategies that could positively impact maintaining post-seismic operations of lifeline corridors. In Year 1, most of the focus was on the development of the three individual ... -
An Innovative Survey Design to Understand Sustainable Travel Behaviors: Potential of a Rolling Sample Survey to Replace Traditional Household Travel Surveys
(2014)We propose an innovative survey with rolling samples to address a major fiscal challenge faced by many MPOs. Faced with a small, but continuous budget, MPOs are increasingly unable to continue the current survey practice: ... -
SSI-Bridge: Soil-Bridge Interaction During Long-Duration Earthquake Motions
(2014)The seismic response of a complete soil-bridge system during shallow, crustal and subduction zone earthquakes is the topic of this report. Specifically, the effects of earthquake duration on the seismic performance of ... -
The Use of Synthetic Blended Fibers to Reduce Cracking Risk in High Performance Concrete
(2014)Transportation departments have observed varying degrees of cracking in their concrete structures. Cracking of high performance reinforced concrete structures, in particular bridge decks, is of paramount concern to Pacific ... -
Digital Dissemination Platform of Transportation Engineering Educational Materials
(2014)National agencies have called for more widespread adoption of best practices in engineering education. To facilitate this sharing of practices we will develop a web-based system that will be used by transportation engineering ... -
Rendering of Dense, Point Cloud Data in a High Fidelity Driving Simulator
(2014)Driving Simulators are advanced tools that can address many research questions in transportation. Recently they have been used to advance the practice of transportation engineering, specifically signs, signals, pavement ... -
Educating Teenage Drivers in the Pacific Northwest Regarding the Dangers of Distracted Driving (Phase I)
(2014)The goal of this outreach project was to examine driver distraction among teenagers in the Pacific Northwest. Specifically, to identify secondary tasks they consider distracting and determine their self-reported engagement ... -
Phase II: Correlation Between Experimental and Finite Element Analysis
(2014)In this study, we will monitor the behavior of the Alaska Chulitna Bridge for the specific purpose of assisting the DOT in performing an accurate condition assessment of this bridge. Based on the state-of-the-art SHM ... -
Laboratory Evaluation of Recycled Concrete as Aggregate in New Concrete Pavements
(2014)The Washington State Department of Transportation (WSDOT) has initiated a research project to investigate the use of recycled concrete as aggregates (RCA) in Portland (hydraulic) cement concrete pavements (PCCP). The planned ... -
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 ... -
Second Generation Accessible Pedestrian Systems
(2014)The Americans with Disabilities Act of 1990 has had a great impact on the implementation of Accessible Pedestrian Systems that target accessible and safety impediments faced by pedestrians with mobility and visual impairments. ... -
Investigation of Anchor Nut Loosening in High-Mast Light Poles Using Field Monitoring and Finite Element Analysis
(2014)High mast lighting poles (HMLPs) are cost effective structures for lighting highways and intersections. They are 100 to 250 feet (30m to 76m) tall, and can hold a variety of lamp configurations. They are commonly used at ... -
Developing a Robust Survey Methodology for Collecting Information on the Port Truck Drayage Industry
(2014)This paper describes the population characteristics in the drayage trucking population of the Port of Seattle as determined by the 2013 Truck Driver Survey. The 2013 Truck Driver Survey was created to give the Port of ... -
Assessment of a New Screening Model for Use in Siting Near-Road NO2 Monitors
