“…These costs depend on the maneuver model and on the air conflict solver used, since its performance will impact the commands issued. We observe again that if the traffic becomes twice as dense, no controller will be able to monitor and issue maneuvers without an automated tool [12]. Thus, a conflict solver is a valid tool for addressing the ATC costs.…”

International audienceAir traffic in Europe is predicted to increase considerably over the next decades. In this context, we present a study of the interactions between the costs due to ground-holding regulations and the costs due to en-route air traffic control. We describe a traffic simulator that considers the regulation delays, aircraft trajectories, and air conflict resolution. Through intensive simulations based on traffic forecasts extrapolated from French traffic data for 2012, we compute the regulation delays and avoidance maneuvers according to two scenarios: the current regulations and no regulations. The resulting cost analysis highlights the exponential growth in regulation costs that can be expected if the procedures and the airspace capacity do not change. Compared to the delay costs, the costs of the air traffic control are negligible with or without regulation. The analysis reveals the heavy controller workloads when there are no regulations, suggesting the need for regulations that are appropriate for large traffic volumes and an improved ATC system. These observations motivate the design of a third scenario that computes the sector capacities to find a compromise between the increase in the delay costs due to ground-holding regulations and the increase in the controller workload. The results reveal the sensitivity of the delay costs to the sector capacity; this information will be useful for further research into ATM sector capacity and ATC automated tool design. Finally, because of the growing interest in the free flight paradigm, we also perform a traffic and cost analysis for aircraft following direct routes. The results obtained highlight the fuel and time savings and the spatial restrictions that companies use to avoid congested areas

“…A study of traffic complexity [12] states that if the traffic becomes twice as dense, no controller will be able to monitor and issue maneuvers without an automated tool, which indicates the need for optimization in this domain. Automated ATC has been thoroughly studied, and numerous algorithms have been developed.…”

“…As part of the development of the RTA prototype, one of the key areas of focus has been examining the impact of introducing decision support automation to the controller's allocation of visual attention and workload. Previous research has shown that ATC automation tools can have a positive impact in reducing the perceived workload of controllers in En Route environments [3]. The objective of this research effort was to gather objective, quantifiable indicators of workload, which could be used to assess the potential benefits of the RTA prototype for terminal applications.…”

A decision support aid to assist controllers in merging Area Navigation (RNAV) flows was evaluated by the MITRE Corporation's Center for Advanced Aviation System Development (CAASD). The goal of this effort was to gather objective performance data to quantify the benefits of an automation prototype on the demands of the Air Traffic Control (ATC) task. A dual-task methodology was used to assess the spare cognitive/perceptual resources of an experienced controller when managing traffic with and without the automation. Two implementations of the automation were evaluated, one where the controller communicated with the flight crew via voice and another via datalink. The results suggest that a dual-task methodology can help quantify the benefits of ATC automation in terms of assessing controller cognitive/perceptual resources.

“…Galster et al (2001) argue that controllers had difficulty both in detecting conflicts and in recognizing self-separating events in saturated airspace according to performance and workload measurements. A number of factors affect controller workload; these factors include, but are not limited to, potential conflicts, number of handoffs, heading and speed differences, aircraft proximity to each other, sector boundaries, presence of severe weather, and traffic density (Kopardekar et al, 2009).…”

In parallel with the rapid growth in Turkish air transportation, air traffic density and congestion of Turkish airspace have been increasing in recent years. The aim of this study is to examine the structural features and the capacity of Turkish airspace. In this context, the map of Turkish airspace containing sector boundaries, routes and waypoints is digitized and transferred to the GIS environment. The real traffic data of Turkish airspace for a period of two peak hours in heavy traffic during August 2007 was provided by the General Directorate of Turkish Airports. Analysis results indicate that the traffic density of Turkish airspace is accumulative especially in certain sectors. The results obtained from the analyses were compared with the existing sector structure of Turkish airspace and some suggestions related to capacity problems are provided. These suggestions can also be used for the strategic planning of airspace.
