ABSTRACT Little research has been conducted to understand the difference in driving performance between younger-old adults (60-75 years) and older-old adults (76+ years), or simply younger olds and older olds. The main objective of this study was to determine if a minimal increase in road light level (luminance) differently affects the performance of these two distinct age groups. Older adults...

Conditions of high and low optic flow were generated in a display used for a driving simulator. Thirty drivers were requested to produce vehicle speeds of either 30 or 60 mph with the geometric field of view at 25, 55, or 85 visual degrees. Drivers overestimated the production of 30 by 20 mph. It was also found that the production of speed was highly dependent on the geometric field of view. Th...

This paper analyzes the behavior of drivers using Adaptive Cruise Control (ACC) within the theoretical framework of Human–Machine Cooperation. The study was carried out on a driving simulator. Driving task performance data and responses to a trust questionnaire were analyzed in order to examine the relationship between driver reliance on ACC and such intervening variables as trust, perceived wo...

This paper investigates how matching age of driver with age of voice in a conversational in-vehicle information system affects attitudes and performance. 36 participants from age groups, 55 -75 and 18 25, interacted with a conversational system with young or old voice in a driving simulator. Results show that all drivers rather communicated with a young than old voice in the car. This willingne...

Driver distraction is a high priority topic for NHTSA. NHTSA has concerns that drivers are making potentially dangerous decisions about when to interact with in-vehicle technologies while driving and that this trend may accelerate as new technologies become increasingly available and easier to use. NHTSA has conducted research in the area of driver distraction and workload since 1991. The objec...

Our study explores eye movements and driving behaviour in safety-critical situations. We collected eye movements from subjects instructed to drive predetermined routes in a driving simulator. While driving, the subjects performed various cognitive tasks designed to divert their attention away from the road. The subjects were divided in two groups, a control and a “gaze-contingent cue” (GCC) gro...

Cognitive dysfunction caused by some neurodegenerative diseases is associated with an increased risk of traffic accidents. Previous studies have reported inconsistent results for prodromal and early stages of dementia. Few studies have directly compared the effects on driving performance of amnestic subtype of mild cognitive impairment (aMCI) with those by normal aging in elderly drivers. The p...

With a growing number of in-vehicle systems integrated in contemporary cars, the risk of driver distraction and lack of attention on the primary task of driving is increasing. One major research area concerns eyesoff-the-road and mind-off-the-road that are manifested in different ways for input and output techniques. In this paper, we investigate in-vehicle systems input and output techniques t...
