Abstract
Abstract. “Air population” refers to the total number of people flying above the earth at any point in time. The total number of passengers can then be estimated by multiplying the number of seats for each aircraft by the current seat occupancy rate. Using this method, the estimated air population is determined by state for the airspace over the United States. In the interactive, real-time mapping system, maps are provided to show total air population, the density of air population (air population / area of state), and the ratio of air population to ground population.
Highlights
For purposes of this study, air population is defined as the number of people who reside above the earth at a particular point in time
The system is based on the Automatic Dependent Surveillance-Broadcast (ADS-B) that broadcasts the precise and instantaneous location of aircraft
Data gathering is accomplished through different types of ADS-B receivers
Summary
A number of studies have examined US Census Bureau American Community Survey data on daytime populations at the county level (Badhuri 2008, Laughlin, et al, MacKenzie, et al.). While the ratio of daytime and nighttime population varies for cities throughout the world, all cities exhibit a commuter pattern that results in major diurnal shifts in population. Another population shift takes shape in the sky everyday as people commute across large distances. For purposes of this study, air population is defined as the number of people who reside above the earth at a particular point in time. The purpose here is to map air population for the United States by state throughout the day
