Intelligent vehicle systems have introduced the necessity for the designer to take care of user preferences in order to make as comfortable as possible several kinds of driving features. This requirement originates the problem of a suitable analysis of the human performances to be implemented in automatic driving tasks. The aim of this paper is to personalize an Adaptive Cruise Control with Sto...

Driver drowsiness is a major, though elusive, cause of traffic crashes. As part of its IVHS/human factors program, NHTSA is supporting research to develop in-vehicle systems . to continuously monitor driver alertness and performance. Scientific support for the feasibility of this countermeasure concept is provided by research showing that: l Drowsy drivers typically do not “drop off’ instantane...

driving is a complex psychomotor task involving distinct cognitive, perceptual and decision making skills. it needs to more concentration and alertness to driving safe. several studies have shown the potential effects of alcohol in crash production by epidemiological and laboratory analysis. alcohol is obviously the most common single cause of traffic accidents in america. a review of the relat...

We apply game theory to a vehicular traffic model to study the effect of driver strategies on traffic flow. The resulting model inherits the realistic dynamics achieved by a two-lane traffic model and aims to incorporate phenomena caused by driver-driver interactions. To achieve this goal, a game-theoretic description of driver interaction was developed. This game-theoretic formalization allows...

Task performance and fatigue during driving may be influenced by psychological factors since individuals differ in temperament and anxiety status. Fatigue has also been shown to be associated with changes in brain wave activity. However, research on psychophysiological associations with driver fatigue is scarce. Understanding the psychological links could provide information for educating the p...

The development of a shock-induced detonation driver for enhancing the performance of a shock tube is described. The detonation wave is induced by the expansion of helium or air. Various gaseous fuel–oxidizer combinations are examined. This method produces a detonation wave which propagates downstream that transitions into a shock wave in the driven section. High-enthalpy flows with a maximum t...

This paper presents a driver performance map of braking and steering in response to three driving scenarios that lead to rear-end crashes. This map encompasses low risk, conflict, near-crash, and crash imminent driving states that correspond to advisory warning, crash imminent warning, and crash mitigation functionalities for intelligent vehicle rear-end crash countermeasures. Specifically, thi...
