The controller  115  is configured to adjust operation of the elevator system  101  in response to the discharge landing  32 . 
     The discharge landing  32  may change based upon the fire detection  76 , the fire intensity  64 , the people count  94 , and the weather data  82 . For example, if the fire  20  is spreading quickly then the elevator system  101  may not have enough time to take people all the way to the bottom landing  125   a  (e.g., a first discharge landing, original discharge landing, or standard discharge landing) and thus the discharge landing  32  may move closer to the landing  125  (e.g., a second discharge landing) where the fire  20  was detected in order to make shorter trips to the new discharge landing  32  to evacuate more people  320  away from the fire  20 . Once safely away from the fire  20  people  320  may then utilize stairs to completely evacuate the building  102 . In an embodiment, the analytic engine  30  may implement a handicap mode to override the current discharge landing  32  and transport handicap passenger directly to a landing  125   a  at the bottom of the building  102 . 
     The occupant evacuation system  10  may also include a display device  50 . There may be a display device  50  located on each landing  125   a - 125   i  proximate the elevator system  101 . The analytics engine  30  is configured to transmit the discharge landing  32  to the display device  50 . The display  50  is configured to receive the discharge landing  32  from the analytics engine  30  and visually display the discharge landing  32 . Advantageously, this will allow people  320  to know what landing  125  they will be traveling to prior to entering the elevator car  103 . The display  50  may also be configured to visually display how long (e.g., a countdown time) until each elevator car  103  of each elevator system  101  arrives at each landing  125   a - 125   i . Advantageously, the display devices  50  will allow people  320  waiting in the elevator lobby  310  to know which elevator cars  103  will arrive soon and thus the people can crowd around the correct elevator system  101  if there is more than one elevator system  101 . The display device  50  may also be utilized to provide a people count  94  in real time. The people count  94  may be continuously updated or updated at a selected interval. The display device  50  may also allow people  320  to update the people count  320  manually. The display device  50  may also allow people  320  to activate a handicap mode as aforementioned. 
     Referring now to  FIG. 3 , while referencing components of  FIGS. 1 and 2 .  FIG. 3  shows a flow chart of method  400  of operating an elevator system  101  during a fire evacuation, in accordance with an embodiment of the disclosure. In an embodiment, the method  400  may be performed by the occupant evacuation system  10  and/or the analytics engine  30 . 
     At block  404 , a fire detection  76  from a fire alarm system  70  indicating a fire is received. At block  406 , a fire intensity  64  is detected using a fire quantity measurement system  60 . The fire intensity  64  may be detected using a fire intensity sensor  62   a - 62   i . The fire intensity sensor  62   a - 62   i  may include a thermal sensor  66  configured to detect thermal data, a smoke quantity sensor  68  configured to detect smoke quantity data, or some combination thereof. At block  408 , a discharge landing  32  for the elevator system  101  is determined in response to at least the fire intensity  64 . 
     The method  400  may further comprise that weather data  82  is obtained using an external weather sensing system  80  and the discharge landing  32  for the elevator system  101  is determined in response to at least the fire intensity  64  and the weather data  82 . 
     The method  400  may further comprise that a people count  94  is obtained using a people counter system  90  and the discharge landing  32  for the elevator system  101  is determined in response to at least the fire intensity  64 , the weather data  82 , and the people count  94 . The people count  92  being a number of people  320  located on a landing  125  where the fire  20  is located. The discharge landing  32  for the elevator system  101  may also be determined in response to at least the fire intensity  64  and the people count  94 . The method  400  may further comprise displaying the discharge landing  32  on a display device  50  located on a landing  125  where the fire  20  is located. 
     The method  400  may additionally comprise that analytics engines  30  transmits the discharge landing  32  to the controller  115  of the elevator system  101  and the controller  115  instructs the elevator system  101  to transport people  320  from a landing  125  where the fire  20  is located to the discharge landing  32  using an elevator car  103  of the elevator system  101 .
