The effects of a simulated head-up display speedometer on perceptual task performance

Applied Ergonomics, 1991

Subjects were 20 male and female volunteers ranging in age from 19 to 51 years. A videotape, taken from the driver's perspective, of a car traveling along a memorized route served as the test scene. While viewing the test scene subjects performed tasks related to navigation, speed monitoring, and salient cue detection. The simulated HUD speedometer produced generally superior performance on the experimental tasks; most important, it enabled subjects to respond significantly more quickly to the salient cues. Implications for the effects of HUDs on automobile safety are discussed.

Older driver fitness-to-drive evaluation using naturalistic driving data

Sixty driver assessment metrics related to fitness-to-drive were examined for 20 seniors who were followed for a year using the naturalistic driving paradigm. Principal component analysis and negative binomial regression modeling approaches were used to develop parsimonious models relating the most highly predictive of the driver assessment metrics to the safety-related outcomes observed in the naturalistic driving data. This study provides important confirmation using naturalistic driving methods of the relationship between contrast sensitivity and crash-related events. The results of this study provide crucial information on the continuing journey to identify metrics and protocols that could be applied to determine seniors&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; fitness to drive.

Conventional Versus Moving-Map Navigation Methods

Because in-vehicle moving-map displays were novel at the time, participants had no prior experience using such systems. These methods were compared on various metrics of navigational efficiency and safety. One primary result showed that the total proportion of glance time directed toward driving-related locations (i.e., the forward roadway, mirrors, and the nonnavigationrelated instrument cluster-termed EYEDRIVE) varied significantly across all three navigation methods (memorized route, 0.90; paper map, 0.82; and Etak, 0.60). Despite this important finding, no crashes or near misses were observed during the course of the study. Also, no systematic variations in brake, accelerator, or lane deviations were observed across navigation methods.

Comparing the impairment profiles of older drivers and non-drivers: Toward the development of a fitness-to-drive model

Of the metrics evaluated, 21 showed statistically significant differences, almost all favoring the drivers. Also, it was shown that a logistic regression model comprised of five of the assessment scores could completely and accurately separate the two groups. The results of this study imply that older drivers are far less functionally impaired than non-drivers of similar ages, and that a parsimonious model can accurately assign individuals to either group. With such models, any driver classified or diagnosed as a non-driver would be a strong candidate for further investigation and intervention.

The intensity of auditory warning tones in the automobile environment: detection and preference evaluations

Applied Ergonomics, 1991

Twenty-four subjects listened to tones presented at several intensity levels under three background noise conditions recorded in actual vehicles: relatively quiet (35 mile/h (56 km/h), smooth road), relatively loud (55 mile/h (89 km/h), rough road), and radio (35 mile/h (56 km/h), smooth road, and radio broadcast). Data were gathered on the minimum intensity level (in'decibels (dB) above the masked threshold (MT) required to achieve a consistent criterion detection rate, as well as the preferred tone intensity level (in dB above the MT) in each background noise condition. The preferred levelswere louder than those required to achieve the detection criterion in both the relatively loud and quiet background noise conditions; thus, the preferred levels are the recommended levels under those conditions. This was not the case in the radio condition; therefore, it is recommended that future research efforts evaluate the effects of automatically muting the radio/stereo system when important auditory warning tones are being presented.

An evaluation of the effectiveness and efficiency of an automobile moving-map navigational display

The central-nervous arousal found in the EEG corresponded to distinct increases in heart rate. The moments of SIFA operation after phases of light sleep correlated significantly and positively with increases in heart rate. These increases constituted a physiological overcompensation as far as the physical readiness was concerned, which reached its peak after the task had been performed satisfactorily, constituting additional and superfluous occupational stress. The results of this study indicate clearly that monotony stress is not a result of occupational monotony itself, but the result of the physiological effort which is required in order to regain a level of alertness which allows adequate performance under monotonous conditions.

Thirty-two driver subjects ranging in age from 18 to 73 drove a specially instrumented vehicle on various types of public roadways with varying traffic conditions . Drivers performed both specific navigation system tasks and conventional tasks using dashboard instrumentation . Comparisons were then made between the two types of tasks . Results show that the demand of most of the navigation tasks was comparable to that of one or more conventional tasks . Modifying the remaining navigation tasks to make information more readily available would reduce their demand .
