Capabilities

The ATSL acquired numerous knowledge and capabilities over the years. The ATSL is experienced in running analysis for various air transportation related models and datasets. The following describes the ATSL capabilities in more details.

ATSL Models

Transportation Systems Analysis Model (TSAM)

TSAM is a nationwide transportation planning model to forecast intercity travel behavior in the United States. The ATSL currently uses TSAM to support the Federal Aviation Administration (FAA) and the Joint Program Development Office (JPDO) to forecats the demand for air travel. TSAM can be used to do various nationwide, regional and local analyses of travel demand. Please visit the TSAM website for more information.

Runway Exit Design Interactive Model (REDIM)

REDIM is a computer model developed to locate and design high-speed runway exits at airports. The development of REDIM was sponsored by the Federal Aviation Administration (FAA) and has been used for various runway exit designs across the world. Please visit the REDIM website for more information.

Airspace Occupancy Model (AOM)

AOM is a computer model developed to estimate module and sector occupancies. The ATSL can run various nationwide or regional scenarios to assess the impact of air traffic changes in the National Airspace System (NAS). Please visit the AOM section in the Products section of the ATSL website.

Airspace Encounter Model (AEM)

AEM is a computer model developed to estimate blind conflicts in the airspace under various concept of operations. The ATSL can run various nationwide or regional scenarios to assess the amount of conflicts due to air traffic and policy changes. Please visit the AEM section in the Products section of the ATSL website.

Third-Party Models

Aviation Environmental Design Tool (AEDT)

AEDT is a noise and emissions model developed by the Federal Aviation Administration (FAA). AEDT evaluates aircraft noise impacts around airports. The ATSL has experience in generating custom case studies for local airports to quantify the noise impact changes in the future. Please visit the AEDT website for more information about the model.

Sector Design and Analysis Tool (SDAT)

SDAT is a decision support tool for analysis and design of airspace and traffic flows. The ATSL can provide support in creating custom scenarios and gathering of the necessary data to run successful analyes in SDAT. Please visit the SDAT website for more information about the model.

Airfield Capacity Model (ACM)

ACM is a model developed by the Federal Aviation Administration (FAA) to calculate airport capacity for various operational strategies and meteorological conditions. The ATSL has extensive experience with ACM and has recently calculated the capacity for 2000+ airports.

Airport and Airspace Simulation Model (SIMMOD)

SIMMOD is a model developed by the ATAC Corporation and validated by Federal Aviation Administration (FAA). SIMMOD allows to conduct high-fidelity simulations of airport and airspace operations. The ATSL can provide support in creating custom scenarios and gathering the necessary data to run successful analyses in SIMMOD. Please visit the SIMMOD website for more information about the model.

Reorganized ATC Mathematical Simulator (RAMS)

RAMS is a model developed by ISA Software. RAMS is a gate-to-gate air traffic simulation package. The ATSL can provide support in creating custom scenarios and gathering the necessary data to run successful analyses in RAMS. Please visit the RAMS website for more information about the model.

Basic Aircraft DataBase (BADA)

BADA is a model developed by EuroControl. BADA is a database of aircraft performance. The ATSL uses the BADA database to accurately model aircraft flight paths from takeoff to landing. This data is then used in TSAM, AOM and AEM for example.

NAS Strategy Simulator (NSS)

NSS is model developed by the Federal Aviation Administration (FAA). NSS forecasts the air traffic demand and delays in the National Airspace System (NAS).

Datasets

Enhanced Traffic Management System (ETMS)

The Federal Aviation Administration (FAA) uses ETMS to collect detailed information about all the Instrument Flight Rules (IFR) flights in the National Airspace System (NAS). ETMS data can be used to analyze flight trajectories, air traffic demand, aircraft mix and much more. The ATSL 1995_american_travel_survehas extensive experience in parsing and analyzing ETMS data.

Official Airline Guide (OAG)

OAG is a database that contains the future commercial and cargo airline schedule. The ATSL uses the OAG to analyze the commercial airline network and to forecast its future changes. Please visit the OAG website for more information about the database.

Airline Origin and Destination Survey (DB1B)

DB1B is a database that contains information about 10% of all the commercial airline tickets sold in the United States. The ATSL uses the DB1B to analyze the commercial airline fares between the commercial airports. Please visit the DB1B website for more information about the database.

American Travel Survey (ATS)

ATS is a large-scale survey of intercity travelers in the United States. The ATSL used the ATS to calibrate the Transportation Systems Analysis Model (TSAM). Please visit the ATS website for more information about the database.

National Household Travel Survey (NHTS)

NHTS is a large-scale survey of intercity travelers in the United States. The ATSL used the NHTS to analyze travel behavior changes in the United States. Please visit the NHTS website for more information about the database.
