The Automated Collision Notification System

The NHTSA sponsored Automated Collision Notification (ACN) Project was initiated in October 1995 to design, develop, test, and evaluate a system that can detect and characterize crashes and then automatically send a data message to the public safety answering point (PSAP). The system also opens a cellular telephone voice line between the PSAP and the vehicle occupants after the data message has been received. The system detects crashes in all directions and stores the acceleration time history experienced. The ACN system is able to determine the crash change in velocity, the principal direction of crash force, whether a rollover occurred and the potential for injury in the crash. The system also includes GPS equipment and provides PSAP dispatchers with a mapped location of the crash. The ACN system has been installed in 700 vehicles in Western New York and real world crash data and time of EMS response data is being collected and analyzed.
