How Does ZDOS Measure Parking Lot Usage?

Learn how Zartico measures passenger usage of long-term or economy parking lots at your airport.


We’ll observe parking lots at your airport that are designated “Long-Term” or “Economy”, as long as this parking is not intermixed in the same structure with short-term parking, rental cars, or terminal areas. We’ll use “Long-Term” to represent both Long-Term and Economy.

We’ll also observe off-site parking lots.

Employees are filtered from parking lot observations. More info HERE.

Inbound/Outbound Designation

When a device is observed in Long-Term Parking, we calculate the distance between that device observation and the “Common Evening Location” of that device (where the device lives). If the distance is LESS than 150 miles, the device observation is declared “Outbound” and is included in the Parking insights in the ZDOS. If the distance is MORE than 150 miles, the device observation is removed and not included in Parking insights.

Duplicate Observations on the Same Day

If a device is observed several times in one day in the parking lots, we discard the extra and count it as one observation.


Zartico’s observations are then SUMMARIZED. There will be one accumulated count of devices seen in the parking lots within a month from one city. So our data will say there were 500 devices from Lakeland, FL seen in the Tampa airport in January, 600 in February, 550 in March, etc.

In the ZDOS, you won’t notice that the data is summarized. Summarized data keeps the ZDOS loading and operating lightning-fast. But note that you will not be able to see insights by week, or by day.
