Fig. 14.13 Emergency shelters and example of mobile phones geolocated in New York City.
Emergency response personnel can utilize mobile phone data to answer unknown questions. For
example, where are citizens located within the evacuation zone, or are there areas where additional
police forces should be positioned to reduce congestion?
mobile phone data (over 15,000 phones) collected from OpenCellID in 2011 for
NYC as well as the locations of five emergency shelters (OpenCellID 2011 ). In
this example, mobile phone locations provide enhanced situational awareness of
spatial and temporal population fluctuations, unlike census data which is a static
representation of data collected during the last census. Using mobile phone data, as
shown in Fig. 14.13 , emergency response personnel can determine evacuation routes
to the closest shelters, determine where to position police officers to reroute traffic to
reduce congestion, or estimate how many citizens are at risk in an evacuation zone.

Importance of Evacuations
Emergency evacuations often occur with limited or no planning. Notifying the cor-
rect individuals based on their location and the type of risk is key to minimizing loss
