How is Common Location Used in Airports?

Common Location is an insight from geolocation data measuring visitor origin points.

Zartico uses Common Evening Location (CEL) in measuring geolocation data. 


The Common Evening Location is where a device rests in the evening.


Using an algorithm, and drawing from several months of historical mobile location data, a device’s likely home location is derived based on where it rests during “non work” hours, defined as evenings (6 pm to 8 am) and weekends.


When we observe a device in an airport, we to classify it as an Inbound or an Outbound flyer based on the device’s distance from it’s Common Evening Location (CEL) for that classification.
