Abstract
In the second phase of the SIP ''Advanced Driving Support for Drivers with Visual Field Loss'' project, the effectiveness of driving support systems for drivers with visual field loss was estimated. As a part of this project, we compared the frequency of accidents between drivers with normal vision and those with visual field loss, and calculated the reduction rate of traffic accidents by using the multi-agent traffic environment simulation technology developed by the Japan Automobile Research Institute in the first phase of the SIP. The results can be used to examine the effectiveness of the system for this issue.
