Presentation Transcript
what is it
What is it?
  • Simulation of air traffic over the United States
  • Uses a sample of 51 major airports to simulate
  • Uses latitude and longitude for more accurate travel times
  • Airports act as any airport would, regulating the landing and take-off of airplanes
  • Goal is to chart delays and examine how they propagate thought the system
progress
Progress
  • Geocoder written to obtain latitudes and longitudes from an address
  • Simulator displays the airports using the latitudes and longitudes
  • Airports have a queue for take-off and landing
  • Airplanes have destinations and a projected schedule
    • Used when delay calculations are implemented
geocoding
Geocoding
  • Process by which an address is converted to longitude and latitude
  • I use Google Maps geocoder
    • Send an HTTP request to Google including the address, output format and Google Maps key
    • http://maps.google.com/maps/geo?q=address&output=csv&key=GMAP_KEY
    • Address formatting is important
address formatting
Address Formatting
  • I tried several types of address formatting because I do not have street addresses
  • Airport code works well (BWI, AUS, PHX, etc)‏
  • Code with “airport” attached also works well
  • In order to maximize the number of valid airports the geocoding program tries one form, then the other in the event of a failed request

  • Validation was needed to verify that the latitude and longitude is in the United States
whats next
Whats Next?
  • Implement collision detection and avoidance
  • Animate the traffic and implement path tracing
  • Implement delay calculations and map them to a color
  • Weight traffic in and out of airports with time to more realistically model patterns
