1. INTRODUCTION
Airspace constraints and controller workload are foremost among the factors limiting the airspace capacity. Controller workload is the physical and mental work that the controllers are supposed to undertake so that air traffic can be managed safely [1].
Airspace can be divided into subdivisions to provide more efficient air traffic services and to reduce the effect of the controller workload on Air Traffic Management capacity. This process is called the sectorization [2].
ATS route is a special way designed to ensure that traffic flows are in accordance with air traffic services rules [3]. There could be many intersecting and parallel routes in a sector. The network structure of ATS routes in the airspace may prevent from dividing the airspace into subdivisions. Therefore, ATS routes may need to be rearranged.
Unidirectional routes at the same level (odd and even) can be grouped at two different points so that two different sectors can be established. This method is called "Roundabout" by the European Organization for the Safety of Air …show more content…
However, as air traffic increases, the controller workload becomes the primary determinant of airspace capacity. Therefore, factors affecting workload such as number of aircraft per hour, average flight time per sector, number of potential conflicts, number and quality of coordination units, number of level changes are taken into account to calculate airspace capacity. Real-time and fast-time simulations are often used in controller workload-based methods. Fast-time simulations are insufficient for taking into account human factors such as controller reasoning and thinking. This is why real-time simulations are often used after fast-time simulations. For example, in Japan, after TAAM and SIMMOD fast time simulations are used to calculate sector capacity, the controller workload is evaluated in real-time simulations
