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...

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...

This study investigated the degrees of consistencies in driving behavior when operating a real system (real car), a virtual system (high fidelity driving simulator), and a laboratory system (computer driving game). The same tendency of behavioral consistencies was confirmed among the three systems: i.e., the steering operation demonstrated the highest behavioral consistencies, followed by the a...

The main objective of this study was to determine if a minimal increase in road light level (luminance) could lead to improved driving performance among older adults. Older, middleaged and younger adults were tested in a driving simulator following vision and cognitive screening. Comparisons were made for the performance of simulated night driving under two road light conditions (0.6 and 2.5 cd...

This study presents a driving simulation platform with low cost for the development of driving assistance systems (DAS). The platform uses a combination of two simulation loops: hardware-in-the-loop (HIL) and driver-in-the-loop (DIL). Its hardware consists of a simulation computer, a monitor computer, a vision computer, DAS actuators and a car mock-up. Its main software includes a monitor softw...

Field operational testing for the study of driver behavior requires extensive preparation and precaution measures to limit subjects risk exposure during experiment. Moreover, inherent variability in testing conditions may introduce error in the experiment results. Alternatively, a driving simulator offers the ability to replicate driving situations in a safe and repeatable experimental environm...

Driving simulation is an invaluable tool for conducting driving-related research. In any virtual driving environment, autonomous traffic is necessary to complete the driver's immersive experience. The higher the fidelity of a driving simulator, the more stringent are the requirements for the realistic appearance of autonomous traffic. Unfortunately, an increase in the fidelity, or the complexit...

The use of driving simulation for vehicle design and driver perception studies is expanding rapidly. This is largely because simulation saves engineering time and costs, and can be used for studies of road and traffic safety. How applicable driving simulation is to the real world is unclear however, because analyses of perceptual criteria carried out in driving simulation experiments are contro...
