COCTA Report Summary

Project ID: 699326
Funded under: H2020-EU.

Periodic Reporting for period 2 - COCTA (Coordinated capacity ordering and trajectory pricing for better-performing ATM)

Reporting period: 2016-10-15 to 2017-04-14

Summary of the context and overall objectives of the project

Increasing the efficiency of Air Traffic Management (ATM) reduces the fares for passengers and the costs for air cargo shippers. Moreover, it makes the European air transport industry more competitive. Besides cost reductions, efficiency improvements might also reduce fuel burn, benefitting the environment by abating CO2 emissions. It goes without saying that the high degree of safety must not be negatively affected by any proposed measure.

If ATM capacity exceeds demand, costs for providing ATM services and consequently ATM charges are above the inevitable level. In case of capacity shortages, airlines and other aircraft operators are forced to deviate from their optimum flight plans, leading especially to delays and additional fuel burn. The COCTA project aims at increasing efficiency by better matching ATM capacity and demand.

The COCTA team proposed a redesigned ATM value-chain, also introducing a new process of capacity and demand management. The Network Manager orders capacities from Air Navigation Service Providers at several instances, i.e. at long-term, medium and short term to adjust orders to meet air traffic demand in the cost-efficient manner. On the other side, the Network Manager defines different trajectory products to meet Airspace Users' needs, but also to improve overall network performance.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

In the first year of the project, the COCTA team achieved all the research goals set at the beginning of the project. Following the early modeling efforts, which resulted in the basic model presented at the SESAR Innovation Days 2016 in Delft, the COCTA team further improved the model formulation and its complexity. Moreover, the case study used to test the improved model is of a more realistic size, compared to the initial model. As a foundation for model improvement, the COCTA team first proposed a new ATM value-chain redesign, followed by the initial development of the COCTA capacity and demand management process. Last, but not the least, the COCTA team examined the main data sources, so we expect that the final model will be tested using the real data.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

The COCTA team has already published one paper in one of the leading journals in the field of transportation (Transportation Research Part A: Policy and Practice), and presented one paper and one poster at one of the most prominent ATM conferences (SESAR Innovation Days). Furthermore, two abstracts describing parts of the COCTA research have been accepted for the ATRS World Conference.

In the research so far, the COCTA team first examined the possibility to reduce delay propagation and also to improve schedule adherence of departures and arrivals; using the two real-world case studies, we demonstrated that it is possible to improve both. Furthermore, after examining the results, in a follow up discussion the COCTA project team argues that further improvements are possible, once all the COCTA key research ideas are implemented. The follow up COCTA research focused on improving, on a network level, the overall cost-efficiency, i.e. to reduce the total costs for Airspace Users. The initial results, based on an academic example, demonstrate how the cost-efficiency can be achieved.
