10.Advanced Automatic Collision Notification System: The system is also known as advanced automatic crash notification (AACN) and is the successor to the automatic collision notification (ACN) system. It alerts emergency medical responders, and the real-time crash data from the AACN vehicle telematics system and similar systems can be used to determine whether injured patients need care at a trauma center. By using a collection of sensors, a vehicle telemetry system such as AACN sends crash data to an advisor if a vehicle is involved in a moderate or severe front, rear, or side-impact crash. Depending on the type of system, the data include information about crash severity, the direction of impact, air bag deployment, multiple impacts, and rollovers (if equipped with appropriate sensors). Advisors can relay this information to emergency dispatchers, helping them to quickly determine the appropriate response involving a combination of emergency personnel, equipment, and medical facilities.

Advanced Automatic Collision Notification (AACN) (Augenstein et al. 2007) is a system that predicts the occupant injury severity in a car accident based on information collected by an event data recorder (EDR) and then reports injury severity and location information to medical institutions through an emergency call center. With this system, it is possible to reduce the time between the occurrence of an accident and the subsequent treatment of an injured occupant by a doctor. Therefore, AACN is expected to reduce the number of serious-to-fatal injuries and physical sequelae of traffic accidents. In Japan, an AACN system called D-Call Net has been in operation since 2018, and doctors are dispatched in accordance with the injury prediction information provided by this system. Moreover, the Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) has announced a policy to promote the widespread use of AACN systems, and the evaluation of these systems has begun alongside the renewal of assessment evaluation in 2020 (MLIT 2019). Therefore, the use of AACN is expected to spread rapidly.
