Abstract
When the multiple driving support systems are installed in a vehicle, it is important to inform a driver of multiple
information as the driver can understand each information appropriately. In this study, we proposed the presentation
method of the two different information using the driver’s peripheral vision when the two different information is
presented from a vehicle-infrastructure cooperative system at a blind intersection without a signal. To reduce the
cognitive workload of the multiple information, the first-priority information was presented on the head up display
(HUD) for the driver to understand the first-priority information certainly and quickly. On the other hand, the
second-priority information was presented in the peripheral display installed in the driver’s peripheral vision to
recognize the second-priority information without gazing easily. By using the peripheral display in addition to the HUD,
the driver’s response time to the second-priority information was reduced significantly without a negative effect on the
response time to the first-priority information.
