Development, validation, and application of a parametric finite element femur model
Older, obese, and female occupants have higher risk of serious lower-extremity injuries in frontal crashes. Optimizing vehicle restraints to better protect these vulnerable populations requires finite element (FE) models of the human body that consider the variations in skeletal geometry, body size...
Developing and implementing parametric human body shape models in ergonomics software 
Human figure models included with today’s high-end simulation systems are widely used for ergonomic analysis. Male and female figures can be scaled by inputting standard anthropometric dimensions, such as stature, body weight, and limb lengths to represent a large range of body sizes. However, the...
Development of a real-time prediction model of driver behavior at intersections using kinematic time series data
As autonomous vehicles enter the fleet, there will be a long period when these vehicles will have to interact with human drivers. One of the challenges for autonomous vehicles is that human drivers do not communicate their decisions well. However, the kinematic behavior of a human-driven vehicle...
Effects of protective equipment and body borne gear on seated maximum reach envelopes
Soldiers in military tactical vehicles perform increasingly diverse tasks, including communication and weapons system control. Personal protective equipment (PPE) and body borne gear (BBG) restrict the soldier’s mobility and performance. This study is to quantify the effects of PPE and BBG and...
Experimental effects of pre-drive arousal on teenage simulated driving performance in the presence of a teenage passenger
Teenage passengers increase teenage driving risk, but this may be conditional on events and emotions immediately preceding driving. An experimental simulation study evaluated the effect of pre-drive arousal on risky driving in the presence of a confederate teenage passenger. In a two-by-two between...
Statistical prediction of body landmark locations on surface scans
Automatic location of body landmarks on human three - dimensional surface scan data can improve the efficiency of anthropometric studies. Previous methods have relied on local features and heuristics to identify landmarks. This paper presents a purely statistical technique based on a statistical...
Intelligent vehicles + infrastructure to address transportation problems: a strategic approach
Transportation systems around the world are showing signs of strain, and safety, congestion, and energy usage are significant societal problems. In the past, transportation professionals have attempted to solve these problems through largely "siloed" approaches focused on vehicle crashworthiness,...
Pre-frontal cortex activity of male drivers in the presence of passengers during simulated driving: an exploratory functional near-infrared spectroscopy
Adolescents are more likely to be involved in motor vehicle crashes in the presence of peer passengers, and risky driving behaviors of male teenagers increase in the presence of male peer passengers. There could be several mechanisms of the influence of peer passengers, however it is evident that...
Effects of occupant size, military gear, seatbelt type, and advanced seatbelt features on occupant kinematics in tactical vehicles during frontal crashes
Statistical models from a previous study that predict male and female femur geometry as functions of age, body mass index (BMI), and femur length were updated as part of an effort to develop lower-extremity finite element models with geometries that are parametric with subject characteristics. The...
Development of methods to assess self-reach capability
Body armor worn by soldiers adversely affects the performance of some physical tasks. These restrictions may also affect the ability to “self-reach” to locations on their own bodies or on their body borne gear. This paper describes the development of laboratory methods to quantify selfreach...
