====== Temporal networks ======




**Dataset:**   ''flights''  - Flights

We constructed two temporal networks. A one-mode network of internal US flights  ''USflights.ten'' from the database http://www.transtats.bts.gov/Fields.asp?Table_ID=311 

"This table contains domestic non-stop segment data reported by both U.S. and foreign air carriers, including carrier, origin, destination, aircraft type and service class for transported passengers, freight and mail, available capacity, scheduled departures, departures performed, aircraft hours, and load factor when both origin and destination airports are located within the boundaries of the United States and its territories. For a uniform end date for the combined databases, the last 3 months U.S. carrier domestic data released in T-100 Domestic Segment (U.S. Carriers Only) are not included."

The other network ''Flights.ten'' is based on the database  http://www.transtats.bts.gov/DL_SelectFields.asp?Table_ID=260 . It is less interesting because it doesn't contain the information about the flights between non US-airports - it is essentially a two-mode network US-airports X non US-airports:

"The Air Carrier Statistics database, also known as the T-100 data bank, contains domestic and international airline market and segment data. certificated U.S. air carriers report monthly air carrier traffic information using Form T-100. Foreign carriers having at least one point of service in the United States or one of its territories report monthly air carrier traffic information using Form T-100(f). The data is collected by the Office of Airline Information, Bureau of Transportation Statistics, Research and Innovative Technology Administration."

It still needs to be transformed into a two-mode format.


===== Description =====

The network ''USflights.net'' contains a multirelational temporal network of internal flights between US-airports. It contains 2126 nodes (airports), 5629896 arcs (flights/month) and 493 relations (companies) over 295 months (Jan-90 to Jun-14). The weight on arcs is he number of passangers per month. It was transformed into Ianus network ''USflights.ten'' merging the relations.

The network ''flights.net'' contains a multirelational temporal network of flights between US-airports and non US-airports. It contains 2776 nodes (airports), 1308680 arcs (flights/month) and 633 relations (companies) over 295 months (Jan-90 to Jun-14).  The weight on arcs is he number of passangers per month. It was transformed into Ianus network ''Flights.ten'' merging the relations.

===== History =====

  * January 2015: CSV files downloaded from BTS site.
  * January 22, 2015: Vladimir Batagelj transformed the CSV data into Pajek format (''flights.net'') and into Ianus TEN format (''flights.ten'').
  * February 1, 2015: Vladimir Batagelj downloaded US data from BTS site and  transformed the CSV data into Pajek format (''USflights.net'') and into Ianus TEN format (''USflights.ten''). The file ''bestUS50.ten'' was also created.
