Optimal speed limit for shared-use roadways
Motor vehicle crashes are a serious social problem in the United States. Each year a large number of motor vehicle crashes occur and many people are killed or injured, resulting in substantial economic costs. To minimize economic costs, it is necessary to determine optimal speed limits on roadways …

Poroviscoelastic Modeling of the Mechanical and Fluid Response of Liver Tissue in Unconfined Compression
Crash injury prevention research has yielded many preventative measures that work in conjunction to protect vital areas of the human body. However, some of these methods of fatality prevention have been shown to increase injury frequency in other areas of the body, including the abdomen. Within the …

Identifying Secondary Crashes by Using Geographic Information System (GIS) and Determining the Secondary Crashes Characteristics
… 2014). The risk of the occurrence of secondary crashes can be six times higher in the presence of a primary crash than that at a normal traffic condition (Yang et al., 2013 and Tedesco, 1994). The purpose of this study is 1) to develop a method to identify the secondary crashes with the primary …

DEVELOPMENT OF SIMILARITY SCORING TECHNIQUES FOR MOTOR VEHICLE CRASH COMPARISONS
Motor vehicle crashes result in thousands of deaths and millions of injuries each year in the United States (US). To help prevent these injuries and deaths, the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) conduct crash tests, which …

From Crash to Care: A Road Towards Improved Safety and Efficiency of Emergency Medical Response
Motor vehicle crashes (MVCs) are a global public health concern. In 2020 alone, there were an estimated 6.76 million police reported crashes in the United States [1]. In the wake of an MVC, those involved may have been inflicted with serious or fatal injuries. Despite large research and development …

Influence of Advanced Airbags on Injury Risk During Frontal Crashes
… use rate of over 85% U.S. drivers involved in crashes continue to be at risk of serious thoracic injury. One hypothesis is that this risk may be due to the lack of airbag deployment or the airbag \'bottoming-out\' in some cases, causing drivers to make contact with the steering. The objective …

Development of a Finite Element Based Injury Metric for Pulmonary Contusion
Motor vehicle crash (MVC) and its associated injuries remain a major public health problem world wide. In 2005 alone there were 6 million police-reported crashes in the United States resulting in 2.5 million injuries and 46,000 fatalities. The thorax is second only to the head in terms of frequency …
