Designing scheme for autonomous driving of a group of vehicles is a growing field in the area of intelligent transportation systems (ITS). The idea of autonomous vehicle platooning in automated highways for optimizing the traffic and fuel, and also enhancing the safety and comfort of the...
In the past decades, nanostructured materials have opened new and fascinating avenues for research. Nanopolycrystalline solids, which consist of nano-sized crystalline grains and significant volume fractions of amorphous grain boundaries, are believed to have substantially different response to...
This project focuses on the development, validation, and sensitivity analysis of finite element models of high-tension cable barrier systems. The literature review details the available cable barrier systems, performance reviews of high-tension systems, and the previous development of a...
At the present time, the crash safety of new and concept vehicle designs, i.e., with advanced materials or structure or powertrains, is primarily assessed through computer simulations of single-vehicle crash test protocols specified by existing regulations and consumer information programs....
Vehicle rollovers are a rare crash event on the roads in the United States, however 10% of all fatalities are caused by rollovers. The FMVSS 216 test is the only established standardized test for evaluation of roof strength currently used by the National Highway Traffic Safety Administration...
It is important to understand the dynamic failure behavior of structures subjected to impact loading in order to improve the survivability. Materials under impact are utterly affected by large deformations, high strain-rates, temperature softening and varying stress-states, which finally may lead...
Cable barriers are an alternative safety countermeasure to rigid or semi-rigid barriers (Guardrails, Concrete Barriers, etc.) for run-off-road crashes on highways with moderate to light traffic flow. Due to their low installation cost and reduced impact severity, the State DOTs have installed...
Roadside hardware devices play an important role in vehicle safety, they redirect vehicles, reduce their speed and absorb impact energy. All roadside hardware devices have to undergo extensive testing procedures in order to validate and guarantee their performance. In order to reduce costs and to...
This thesis is part of current research at Center for Intelligence Systems Research (CISR) at The George Washington University for developing new in-vehicle warning systems via Brain-Computer Interfaces (BCIs). The purpose of conducting this research is to contribute to the current gap between...
The objective of this work is to evaluate thoracic injuries for restrained occupants in far-side rollover and to propose a dynamic rollover test device. Most rollover studies have been driven by litigation and mainly focused on head and spinal injuries, while thoracic injuries, which correspond...
