The increase in traffic accidents due to the decline in driving ability of elderly drivers has been a problem. We investigated the relationship between the frequency of emergency braking for collision avoidance per mile driven measured by a drive recorder of 25 elderly drivers aged 59 to 86 years and their driving ability evaluation in urban areas by a driving instructor. It was found that elderly drivers who had a high frequency of emergency braking for collision avoidance had a low rating of driving ability.

We examined the effects of visual field training on driving performance and dynamic useful field of view (UFOV) in elderly drivers. Participants performed the dynamic UFOV task while driving in an immersive driving simulator (DS). The intervention group received visual field training with a tablet device twice daily, while a control group did not receive any training, and both groups again performed the DS driving test one week later.

With the aim of optimizing and encouraging the spread of individualized and effective safe driving support, in this report, data from a web-based survey of 1650 elderly group members in their 60s to 80s were analyzed. By using the ranks obtained from the SQ-CCDC (Simplified Questionnaire Comprehensively Captures Driving Characteristics), multiple correspondence analysis was carried out, and the features of the subjective evaluation could be visually grasped.

Evaluation of the Influence of Information to Encourage Early Detection of Pedestrians for Right Turning Driver's Behavior at Signalized Intersections

We displayed an icon to inform the drivers of the presence of crossing pedestrians when turning right at a signalized intersection. And the effect of the icon for driving behavior was evaluated. Using the virtual reality driving simulator (VRDS), we conducted an experiment in which two types of information were displayed. The results suggested that the display of information helps to detect pedestrians earlier and leads to a reduction in unsafe driving.

The effect of the visual information by the digital rear-view display on the reduction of accident risk during lane-change task was evaluated by using the driving simulator. From the results, we gained insight into the proper field of view angle and attachment position of the camera for rear-view display, which would help drivers to change lanes in more safe manner.
