TRAFFIC GENERATORIntroduction

• Main tasks performed by the Traffic generator
  module
• Imports data
• Prepares data automatically
• Associates arrivals and departures to create
  ground movements
• Generates traffic
• Allocates SIMMOD routes to each flight
• Corrects simulator entry time for arrivals (using
  SIMMOD dbf files)
• Exports data to flight.dbf and continuing_departur
  e.dbf

TRAFFIC GENERATOR Random process and traffic
structure

• How to keep the traffic structure of the day of
  reference ?
• Define groups of days
• Determine the group of the day of reference
• Extract from the pool of ground movements (AD)
  those with the same group as the day of reference

 
12
TRAFFIC GENERATORTime correction module (route
delay)

• This module determines how much time each type of
  aircraft will spend on each route.
• Route delays are calculated using the data
  extracted from SIMMOD dbf files
• Length of each route segments
• Average speed on each segment for a selected type
  of aircraft
• SIMMOD Time (A)
• landing time route delay

14
TRAFFIC GENERATORDBF Exportation module
This module is mapping data between pre-processor
columns and SIMMOD tables columns. Automatic
generation of SQL requests for the exportation.
