NOTIFICATION DEVICE

A notification device, provided on a vehicle performing an evacuation or an emergency stop when a failure occurs, includes an optical notification unit provided on the vehicle and configured to emit light toward an outside of the vehicle, a notification direction specifying unit configured to specify a notification direction based on a current vehicle location or a scheduled stop location of the vehicle and map information or an external environment of the vehicle, wherein the notification direction is a direction in which notification is performed using the optical notification unit when the failure occurs, and an optical notification control unit configured to perform a failure notification control of the optical notification unit when the failure occurs. The optical notification control unit controls the optical notification unit such that the notification toward directions other than the notification direction is suppressed as compared with the notification toward the notification direction.
