Presentation of multiple driving support information using the driver`s peripheral vision at blind intersection

The driving support systems which can provide information of the surrounding vehicles or pedestrians to the driver has a large potential to reduce traffic accidents and are expected to become widely used. Human machine interface (HMI) is one of the important issues to support the driver’s understanding of the information and avoid the traffic accident. 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 in the condition that 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 is 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 is 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 is reduced significantly without a negative effect on the response time to the first-priority information.
