Filter by Keyword24 report(s) found with health in the keywords field This report describes methods that allow for assessing structural integrity using a direct porting of imaging methods captured by both hand-held and uncrewed aircraft system (UAS)-assisted photography into computational analysis tools to monitor structural degradation of transportation structures. Of... This study proposes a new remote sensing technique to measure three-component (3C) dynamic displacement of three-dimensional (3D) structures. A sensing system with an unmanned aerial vehicle (UAV) platform and contact-free sensors (e.g., optical and infrared (IR) cameras) was employed to provide a portable... Measuring the dynamic displacements of a structure provides a comprehensive understanding of the structure, especially when subjected to different types of dynamic loading (i.e., wind, traffic, impact loads, blast loads). Despite their usefulness, direct displacement measurements are typically not collected... This comprehensive report synthesizes findings from three distinct yet interrelated studies, each exploring the developing role of drones in the condition monitoring of multimodal transportation assets. The first study, a systematic literature review (SLR) on railway inspection and monitoring (RIM)... This research examines the many ways that public transportation affects health, with a focus on rural and small urban areas. First, a comprehensive literature review is conducted. Research on the social determinants of health, access to health care, physical activity benefits, social isolation, and mental... Food insecurity is a persistent problem in the United States that is disproportionately distributed across racial groups. Native American tribes, many located in rural areas, have high rates of food insecurity. Transportation plays a role in the limited access to food. This study focused on transportation... The current pandemic has affected the lives of all Americans. Rural communities are particularly vulnerable because of a lack of mobility services and the great distances individuals must travel for healthcare and other needs. Nearly five million veterans live in rural communities, representing 57% of... The recent rapid development of commercial unmanned aerial vehicles (UAVs) has made collecting images of bridge conditions trivial. Measuring a defect's extent, growth, and location from the collected large image set, however, can be cumbersome. This paper proposes a streamlined bridge inspection system... The number of Americans age 65 and older is projected to nearly double from 52 million in 2018 to 95 million by 2060, and the 65-and-older age group's share of the total population will rise from 16% to 23% (US Census 2018). Also, average U.S. life expectancy increased from 68 years in 1950 to 78.6 years... Bridge inspection data is an essential step in the bridge asset management operation and the bridge management system. As such, a reliability-based, holistic framework was proposed to effectively collect reliable data and perform data fusion and information fusion of sensory data used for element-level... |
