3D Virtual Sight Distance Analysis Using Lidar Data
(2016)This research project investigated advanced safety analysis methodologies for drivers’ sight distance based on high resolution data acquired using lidar (light detection and ranging) technology. Sight distance analyses ... -
Acquisition of a Vardoulakis-Type Plane Strain Device for Advanced Testing of Soils
(2018)Plane strain loading conditions are present in many transportation-related geostructures, such as long embankments and behind retaining walls. However, the mechanical properties of soils are not typically characterized ... -
Aerodynamic Effects on Two-Lane Rural Highway Safety
(2017)Two-lane rural highways experience a higher rate of traffic accidents than to other types of highways. One factor affecting this rate is the impact of aerodynamics on a vehicle’s stability and safety during crossing and ... -
AGENT-BASED MODELING FRAMEWORK FOR WILDFIRE EVACUATION IN DAMAGED TRANSPORTATION SETTINGS
(2023)The main goal of this project was to support effective evacuation planning by developing an agent-based modeling (ABM) framework for wildfire evacuation in damaged transportation settings. More specifically, the framework ... -
Agent-based Modeling of Emergency Management Networks with Public Mobilization after a Disaster
(2020)Local, state, and federal governments are responsible for managing disaster response with the goal of increasing disaster resilience of a community. This includes continuing adequate service levels for critical infrastructure ... -
AN AIRBORNE LIDAR SCANNING AND DEEP LEARNING SYSTEM FOR REAL-TIME EVENT EXTRACTION AND CONTROL POLICIES IN URBAN TRANSPORTATION NETWORKS
(2020-01)Airborne light detection and ranging (lidar) and unmanned aircraft systems (UAS), also called drones, are emerging technologies that are of growing interest for a range of transportation applications. At the same time, ... -
Alternative Information Signs: an Evaluation of Driver Comprehension and Visual Attention
(2015)The effectiveness of a traffic sign is collectively influenced by the sign’s understandability, legibility distance, glance legibility, and learnability; however, understandability has been repeatedly identified as a one ... -
Analysis of Roadway safety under Alternative Project Delivery Systems
(2017)In the United States, most highway projects have been with using the traditional design-bid-build delivery system. Moving on to regular conditions assessment, maintenance of a road is then performed on the basis of the ... -
Analytical Tools for Resilience of Lifeline Highway Bridges to Tsunami Events
(2018)Extreme tsunami events in the 21st century, particularly the 2004 Indian Ocean and 2011 Great East Japan events, have put the vulnerability of coastal transportation infrastructure to tsunamis at the front of bridge ... -
Analyzing the Effects of COVID-19 on Human Mobility and Transit Ridership in the Pacific Northwest Region
(2021)This study investigated the effects of COVID-19 on trip reductions and decreases in transit ridership in the Pacific Northwest region of the United States, encompassing Washington, Oregon, Idaho, and Alaska. By utilizing ... -
Analyzing the Long-term Impacts of COVID-19 Disruption on Travel Patterns
(2020)In this project we collected data from residents of the Puget Sound region on their travel behavior changes during the pandemic and attitudes toward pandemic-related subjects. Data were collected through the Google Forms ... -
Analyzing the Shift in Travel Modes’ Market Shares with the Deployment of Autonomous Vehicle Technology
(2019-08-01)It is generally accepted that automation as an emerging technology in transportation sector could have a potential huge effect on changing the way individuals travel. In this study, the impact of automation technology on ... -
Application of Augmented Reality and Tangible Interfaces to Minimize Work Zone Effects on Mobility through Participatory Planning
(2020)Highway work zones account for about 10 percent of congestion but are an absolute necessity in ensuring that our transportation infrastructure can meet the mobility demands of growing populations. Unlike other causes of ... -
Assessing the Capacity of the Pacific Northwest as an Intermodal Freight Transportation Hub
(2015)This project synthesizes information from multiple sources about the capacity of the Pacific Northwest region to handle intermodal freight transportation demand. The findings from this research are intended to be used as ... -
ASSESSING THE FEASIBILITY OF UTILIZING A UAS-BASED POINT CLOUD IN PAVEMENT SMOOTHNESS/ROUGHNESS MEASUREMENT
(2023)The metric derived from the longitudinal profile IRI (international Roughness Index) is a substantial input for the majority transportation agencies' highway monitoring systems used to improve road safety, increase road ... -
Assessment of a New Screening Model for Use in Siting Near-Road NO2 Monitors
(2014)Near-road monitoring of nitrogen dioxide (NO2) in major urban areas in the U.S. will be required by 2013. It is not yet known exactly how many urban areas will be in attainment of the new NO2 air quality standard, due to ... -
