Evacuation system
A system includes a first sensor configured to identify information regarding an emergency condition associated with a structure and a second sensor configured to identify an occupancy pattern regarding the structure. The system also includes a processor operatively coupled to the first sensor, the second sensor, and a transceiver. The processor is configured to determine a severity of the emergency condition based at least in part on the information regarding the emergency condition and prioritize rescues within the structure based at least in part on the occupancy pattern. The system also includes the transceiver which is configured to transmit an identification of the emergency condition, a location of the structure, the occupancy pattern, the prioritization of rescues, and the severity of the emergency condition.

4 . The method of claim 3 , further comprising:
comparing, by the second node, occupancy information corresponding to the first exit with occupancy information corresponding to the second exit; and
in response to comparing the occupancy information, choosing the second exit for the second evacuation route, wherein comparing the occupancy information indicates that the second exit is less crowded than the first exit.
5 . The method of claim 4 , wherein the occupancy information corresponding to the first and second exits comprises at least one of a number of occupants, a time of occupancy, a historical occupancy pattern, or a predicted occupancy.
6 . The method of claim 1 , further comprising:
determining, by at least one of the first node or a second node, a severity of the evacuation condition at varying locations within the structure;
comparing the severity of the evacuation condition proximate a first exit with the severity of the evacuation condition proximate a second exit; and
in response to determining that the severity of the evacuation condition proximate the first exit is less than the severity of the evacuation condition proximate the second exit, determining the second evacuation route such that the second evacuation route leads to the first exit.
7 . The method of claim 1 , further comprising:
determining a first type of the evacuation condition within a portion of the structure corresponding to the first evacuation route;
determining a first mode of evacuation for the first evacuation route based on the first type of the evacuation condition;
determining a second type of the evacuation condition within a portion of the structure corresponding to the second evacuation route; and
determining a second mode of evacuation for the second evacuation route based on the second type of the evacuation condition, wherein the second mode is different from the first mode.
8 . The method of claim 1 , further comprising:
conveying, by the first node, the first evacuation route to occupants within a first portion of the structure; and
conveying, by a second node, the second evacuation route to the occupants within a second portion of the structure.
9 . The method of claim 1 , further comprising;
receiving, by a third node located within the structure, at least one of the first evacuation route or the second evacuation route; and
determining, by the third node, a third evacuation route based upon the first evacuation route and the second evacuation route.
10 . A system comprising:
a first node located within a structure, the first node comprising: a first memory; and
a first processor operatively coupled to the first memory, the first memory comprising software instructions which, when executed by the first processor, cause the first node to:
receive an indication of an evacuation condition within the structure;
determine a first evacuation route responsive to the indication of the evacuation condition, wherein determining the first evacuation route comprises using an occupancy pattern that has been learned over time by monitoring one or more areas during quiescent conditions; and
determine by the first node, a second evacuation route based on changes in occupancy patterns along the first evacuation route, the second evacuation route further determined by identifying a location along the first evacuation route and matching the location with an ingress of the section evacuation route.
11 . The system of claim 10 , wherein the first evacuation route traverses a first portion of the structure and the second evacuation route traverses a second portion of the structure, and wherein the second node matches a location along the first evacuation route with an ingress of the second evacuation route.
12 . The system of claim 10 , wherein the first evacuation route comprises a first exit, wherein the second evacuation route comprises a second exit, and wherein the second exit is different from the first exit.
13 . The system of claim 12 , wherein the second node compares occupancy information corresponding to the first exit with occupancy information corresponding to the second exit to determine that an area proximate the second exit is expected to be less crowded than an area proximate the first exit, and wherein upon determining that the area adjacent the second exit is expected to be less crowded, the second node chooses the second exit for the second evacuation route.
14 . The system of claim 10 , wherein at least one of the first node or a second node determines a severity of the evacuation condition at a plurality of locations within the structure, wherein the system compares the severity of the evacuation condition proximate a first exit with the severity of the evacuation condition proximate a second exit, and upon determining that the severity of the evacuation condition adjacent the first exit is greater than the severity of the evacuation condition adjacent the second exit, the second evacuation route is determined such that the second evacuation route leads to the second exit.
15 . The system of claim 10 , wherein the system determines a type of the evacuation condition, wherein in response to receiving the first evacuation route using a first mode of evacuating suitable for the type of the evacuation condition, the system further determines a second mode of evacuating suitable for the type of the evacuation condition in the second evacuation route, and wherein the second mode is different from the first mode.
16 . The system of claim 10 , wherein at least one of the first node or a second node transmits the indication of the evacuation condition to an emergency response center.
17 . The system of claim 10 , wherein at least one of the first node or a second node transmits one or more warning messages indicating the first evacuation route and the second evacuation route.
18 . A non-transitory computer-readable media comprising computer-readable instructions stored thereon that when executed by a processor associated with a first node located within a structure cause the processor to:
receive an indication of an evacuation condition within the structure;
determine, by the first node, a first evacuation route responsive to the indication of the evacuation condition, wherein determining the first evacuation route comprises using an occupancy pattern that has been learned over time by monitoring one or more areas during quiescent conditions; and
