Keywords:
Air traffic density, Controlled airspace, Control zone (CTR), Terminal control area (TMA), Suvarnabhumi International AirportAbstract
This research aims to 1) examine the level of opinions of air traffic controllers regarding various factors that may influence air traffic density in controlled airspace at Suvarnabhumi International Airport, 2) analyze and prioritize factors with statistically significant influence, and 3) propose guidelines for the development and management of air traffic density at Suvarnabhumi International Airport. This research is quantitative research. The sample group consisted of 132 air traffic controller’s selected using purposive sampling. Data were collected between May to July 2025 and analyzed using descriptive statistics, including mean, standard deviation, and stepwise multiple regression analysis.
The findings revealed that air traffic controllers had a high level of agreement on all six factors. (x̄ = 4.10). Stepwise multiple regression analysis revealed that four factors had a statistically significant influence (p < .05) on air traffic density, ranked from most to least influential: (1) transportation factors (β = 0.44), (2) airport infrastructure factors (β = 0.35), (3) economic factors (β = 0.29), and (4) air traffic control technology factors (β = 0.19). All four factors could explain 62.2% of the variance in air traffic density (R² = 0.622, Adjusted R² = 0.61). It is recommended that Aeronautical Radio of Thailand Co., Ltd. and related agencies prioritize the development of connected transportation systems and infrastructure, including the introduction of modern technology and continuous training for personnel.
