“…Hence, it is important to make warning signals distinguishable from other signals say the noise from the tape [31]. Therefore, the signal sounds have to differ from each other in at least two of the following factors: fundamental frequency, frequency oscillation, sound pattern intensity and pulse.…”

“…Then a reminder sound consisting of a simple musical chime with one or two tones was given and finally as an imminent warning a short sharp chime with increasing volume was given [31]. The perceptibility of an acoustic signal mainly depends on the loudness of the signal, the ambient background noise, and the complexity of the sound: The researchers recommended that the auditory tones should be about 15 dB above the masked threshold and it should not be more than 115 dB [32].…”

In recent years, driver hypovigilance (drowsiness and inattentiveness) is one of the major causes for road accidents and it leads to severe traumas such as physical injuries, deaths, and economic losses. Several researchers have reported on driver drowsiness detection and only very few works have been reported on detecting the driver hypovigilance. The physiological signals and vision based approaches are mostly used for estimating the driver's hypovigilance. When the physical state of the driver is drowsy or inattentive, it is important to alert the driver through alerting methods to avoid the accidents. In this paper, we have reviewed various methods used to alert drivers and the issues involved in detecting the hypovigilance. There are many methods adopted for alerting the driver during hypovigilance such as alarms, visual effects, vibrations, etc. This present work discusses in detail about the different methods used for driver alertness system. The level of alertness is based on the hypovigilance level of the driver. The hypovigilance detection system should be designed in such a way to efficiently trigger the alert system only when the driver is in hypovigilance state.

“…Aircraft cockpits, nuclear control rooms, space launch control, operating rooms, and commercial products include a host of new technologies aimed at detecting faults or errors in hardware, software, and liveware (human operators) (é wre and Marshall 1986, Baber 1994, Wiener 1988. Operators monitoring and supervising these technologies are armed with an array of sensor-based signalling systems designed to provide information about system trends, impending breakdowns, and actual failures.…”

As automation becomes more prevalent in complex task systems, operators are confronted with a myriad of emergency signals. Although much research has been performed to improve the structure and function of signalling systems, it has concerned mainly those stimuli that are presumed to accurately indicate danger. The current report discusses the general area of emergency signal failure, its implications for complex task performance, and recommendations for design and research. A general description of the problem is followed by a review of the applicability of scienti® c theory to human behaviour during and following signal failure, and the authors conclude with recommendations for personnel training and warning signal design and research.

SUMMARYThe main motivation of the authors of this article is to establish a rigorous definition of the potential capacity that a motor vehicle driver has to avoid a collision against a pedestrian. Henceforth we will call this capacity avoidability.To calculate the avoidability, it is necessary to analyze time, distance and itinerary, initial position of the pedestrian when exposed to the risk, initial speed; theoretical maximum speed developed by the vehicle and road limit speed; the driver's reaction time and the influence of the environment; and the interrelation of the initial positions of vehicle and pedestrian with respect to the transversal axis of the road.The definition, categorized by variables, of a driver's ability to avoid run over a pedestrian in an urban area has an evident usefulness: it allows knowing the influence of the initial speed of a vehicle as an isolated variable and the importance of the road limit speed in the ability to prevent an accident.
