An airport node-link network model is an important input for most airport simulation models. Developing, maintaining and updating detailed airport surface node-link models require significant work. A model to convert airport geographic and geometric information into a node-link network is thus needed. In this thesis, an efficient model to automate the procedure of converting airport geographic and geometric information into a node-link network is proposed. The geographic and geometric information are obtained from the Aeronautical Information Exchange Model (AIXM). The node-link network is generated by converting the geographic and geometric information contained into the AIXM files using coincident geometry management and polygon representation development. Finally, using the airport node-link network generation model, a standalone computer application, called Taxiway Toolkit, is developed to improve the Airfield Delay Simulation Model (ADSIM+). / Master of Science
