System and method for evacuation based on shooting sound detection

An active shooting sound response station, comprising:

• a sound sensor configured to detect one or more shooting sounds;
• a transmitter configured to transmit detection of the one or more shooting sounds to an active shooting event response server;
• a receiver configured to receive an action command, generated based on the detection of the one or more shooting sounds and a location of the shooting sound response station, from the active shooting event response server;
• an action command display device configured to display the received action command to one or more evacuating persons;
• and
• a processor,
• wherein the action command is generated based on a computed movement time required to move from the active shooting event location to the shooting sound response station based on an estimated active shooting event location, the map detailing physical structures dividing an indoor space, and locations of the shooting sound response stations and computed escape time required to escape from the indoor space from the shooting sound response station, and
• wherein the computed movement time and the escape time are computed by the active shooting event response server based on the detection of the one or more shooting sounds,
• wherein the action command instructs the one or more evacuating persons to escape from the indoor space when the movement time of the shooter is longer than the escape time from the corresponding station,
• wherein the action command instructs the one or more evacuating persons to hide from the shooter when the movement time of the shooter is shorter than the escape time from the corresponding station, and
• wherein the sound sensor is configured to detect a current location of the shooter, and the processor is configured to update the movement time required to move from the active shooting event location to the shooting sound response station based on the current location of the shooter.

An active shooting event response server comprising:

• a receiver configured to receive detection of one or more shooting sounds from shooting sound response stations disposed within an indoor space;
• memory configured to store a map detailing physical structures dividing an indoor space and locations of the shooting sound response stations in the map detailing physical structures dividing the indoor space;
• a processor configured to estimate a location where an active shooting event has occurred based on the received detection of the one or more shooting sounds and the map detailing physical structures dividing the indoor space, and to generate action commands, respectively corresponding to each of the shooting sound response stations based on the estimated location where the active shooting event has occurred and locations of the shooting sound response stations;
• and
• a transmitter configured to transmit the generated respective action commands to the each of the shooting sound response stations,
• wherein the transmitted action commands are displayed to one or more evacuating persons, located within the indoor space, via the shooting sound response stations,
• wherein the processor is further configured to:
• compute movement times required for a shooter to move from the location where the active shooting event has occurred to the locations of the shooting sound response stations based on the location where the active shooting event has occurred, the map detailing physical structures dividing the indoor space, and the locations of the shooting sound response stations;
• and
• compute escape times required for the one or more evacuating persons to escape from the indoor space from the locations of the shooting sound response stations,
• wherein the action command instructs the one or more evacuating persons to escape from the indoor space when the movement time of the shooter is longer than the escape time from the corresponding station,
• wherein the action command instructs the one or more evacuating persons to hide from the shooter when the movement time of the shooter is shorter than the escape time from the corresponding station, and
• wherein:
• the receiver is further configured to receive information about an updated location of the shooter from the shooting sound response stations when the shooter has moved;
• and
• the processor is further configured to update the movement times based on the updated location of the shooter.
