Welcome to the North American SIMMOD User’s Group (NASUG) Homepage The NASUG was formed as a forum for SIMMOD Users to share experiences and information. SIMMOD is the FAA’s Airport and Airspace Simulation Model. SIMMOD is a useful tool for 1) quantifying delay and capacity for an airport and airspace system given varying traffic levels and 2) measuring the benefits of physical or procedural modifications. Three types of data go into a SIMMOD study: 1) the airport and airspace infrastructure, which is depicted as a link-node network; 2) the Air Traffic Control (ATC) rules and procedures; and 3) the aircraft schedule. SIMMOD simulates the movement of all aircraft, step by step, resolving conflicts and keeping track of the travel and delay time along each segment. SIMMOD then produces tabular results of aircraft travel and delay time and displays an animation playback. The NASUG Chair is Dr. Toni Trani of Virginia Tech. The NASUG Secretary is Geoff Baskir of Parsons Brinckerhoff. |
