　　This study develops a microscopic airspace simulation model while accommodating the characteristics of Taipei Flight Information Region (Taipei FIR). The factors taken into account in this model include sectors, aircraft characteristics, separation requirements, flight speed restrictions, en route flight rules, vectoring, and flight levels. This model is developed based on ANS, while taking into account the logic of SIMMOD. The network employed in this model is composed of nodes and links and could accommodate three-dimensional operations. The parameters for each node include flight levels, separation requirements, holding pattern characteristics, arrival and holding rules. Also, the parameters for each link include flight levels, speed restrictions for various aircraft, capacity, passing rules and vectoring time.
　　A comprehensive model validation is conducted in this study. The validation criteria include inter-arrival time and flight time. For each criterion, both the average and the distribution are examined. The results indicate that the model can simulate the operation of Taipei FIR quite well. With some enhancements this model can be applied to the area of real time air traffic management.
