This paper presents a study on multi-modal human emotional state detection while riding a powered wheelchair (PMV; Personal Mobility Vehicle) in an indoor labyrinth-like environment. The study reports findings on the habituation of human stress response during self-driving. In addition, the effects of "loss of controllability", change in the role of the driver to a passenger, are investigated v...

Modeling pavement performance by combining field and experimental data The accurate prediction of pavement performance is important for efficient management of the surface transportation infrastructure. By reducing the error of the pavement deterioration prediction, agencies can obtain significant budget savings through timely intervention and accurate planning. The goal of this research was to...

This paper illustrates the mathematical modeling of passive suspension system and the control strategies for semi active suspension system. The Simulink software developed by Matlab is used to evaluate the control characteristics [1], for the same a 2 DOF quarter car model is used. The comparison and evaluation of control result are made using software-in-the-loop simulation (SILS) method. From...

When people ride an autonomous car, they might feel anxiety because they cannot know how it may move. Adding artificially augmented signals, which represent coming changes of the vehicle, it may be useful to reduce anxiety by change expectation. Thus we executed an experiment examining whether ascending sound could decrease passenger’s anxiety, while riding on virtual autonomous car. In the exp...

IMPORTANCE Driving after marijuana use increases the risk of a motor vehicle crash. Understanding this behavior among young drivers and how it may differ from alcohol-related driving behaviors could inform prevention efforts. OBJECTIVE To describe the prevalence, sex differences, and risk factors associated with underage college students' driving after using marijuana, driving after drinking ...

Objective. To study the impact of helmet use on outcomes after recreational vehicle accidents. Methods. This is an observational cohort of adult and pediatric patients who sustained a TBI while riding a recreational vehicle. Recreational vehicles included bicycles, motorcycles, and all-terrain vehicles (ATVs), as well as a category for other vehicles such as skateboards and scooters. Results. L...

A novel fuzzy-logic-based control for vehicle-active suspension is suggested. The vehicle vibration and disturbance are reduced considerably with a fuzzy logic controller, to enhance comfort in riding faced with uncertain road terrains. A quarter-car active suspension system is controlled to reduce the vertical acceleration to a level of, that of, a hypothetical reference model. A new look-up t...
