***** To join INSNA, visit http://www.insna.org ***** I am pleased to announce the release of AIRNET, a Stata command that parses US air traffic data from the Bureau of Transportation Statistics into weighted and directed networks. To download and install the command, type "ssc install airnet" in the Stata command line. The command and the network data it generates are described in detail here: Neal, Zachary. In press. "AIRNET: A Programme for Generating Intercity Networks." Urban Studies. (available at https://www.msu.edu/~zpneal/publications/neal-airnet.pdf) Here are some of the main features of the available data -- • DYNAMIC: Quarterly intervals from 1993 to present (after 6-9 month embargo) • WEIGHTED: Edges reflect the number of passengers traveling • DIRECTED: Direction of travel is recorded • MULTISCALAR: Nodes can be either US airports or US metropolitan areas • MULTIPLEX: Four distinct types of networks are available • ROUTE: Number of passengers taking off in origin and landing in destination • ORIGIN-DESTINATION: Number of passengers starting journey in origin and ending in destination (i.e. layovers omitted) • BUSINESS: Subset of origin-destination network containing only business passenger movements • LEISURE: Subset of origin-destination network containing only leisure passenger movements === FOR NON-STATA USERS === Pre-constructed network datasets containing annual waves from 1993-2011 at airport or metro levels are available here: https://www.msu.edu/~zpneal/research.html If you use AIRNET or these data, please consider citing: Neal, Zachary. Forthcoming. "AIRNET: A Program for Generating Intercity Networks." Urban Studies. Neal, Zachary. 2010. "Refining the Air Traffic Approach: An Analysis of the US City Network."
