Abstract: A reliability check system for unexpected situation detection information in a mixed traffic flow of a mix of autonomous and non-autonomous vehicles includes a sensor unit configured to detect emergency and disaster situations on or around a road, including at least one of a camera, a lidar, and a radar, an emergency determination unit configured to analyze information received from the sensor unit to determine an emergency type, a controller configured to classify a set grade according to detection information from the emergency determination unit and transmit a response manual to an autonomous vehicle and an on-site terminal, and a data checking unit configured to verify at least one of whether firmware of the information received from the emergency determination unit has been falsified, whether a vehicle is hacked by remote control, whether CAN tampering occurred, and whether communication channel tampering occurred, and transmit verified data to the controller.

Abstract: A signal control system for reducing intersection accidents on mixed roads with autonomous vehicle includes an autonomous vehicle determining whether there is a possibility of collision based on nearby vehicle information, a signal device installed on a road in a specific area and changing a signal display when a collision possibility notification message is received from the autonomous vehicle, a roadside device installed around the road in the specific area and transmitting and receiving data to and from the autonomous vehicle and the signal device, and an integrated control server transmitting and receiving data to and from the roadside device.
