• Reduce delays, increase throughput and predictability of the capacity of major high-volume resources to meet air traffic demand, especially during significant weather events. • Increase the effective utilization of the available airspace and airport capacities through efficient demand management. • Enable the use of airline-generated trajectories and automated trajectory negotiations during pre-departure phase of flight
","description":"Integrated Demand Management (IDM) develops requirements and procedures, validated through high-fidelity experiments, for an integration of near- to mid-term NextGen traffic management capabilities to improve NAS performance when the capacity of critical resources is inadequate to meet demand. Under IDM, strategic Traffic Flow Management Systems (TFMS) tools are used to pre-condition traffic into the more tactical Time-Based Flow Management (TBFM) system, enabling TBFM to better manage delivery to the capacity-constrained destination. Coordinated traffic flow management across multiple airspace, airport, and weather constraint bottlenecks improves throughput and schedule predictability while reducing delays and enabling user-preferred trajectories.

The concept was evaluated in a series of human-in-the-loop simulations to confirm concept benefits in terms of better schedule predictability, reduction of delays, and increased throughput, especially during convective weather. In addition, other conditions with mixed participation of multi-trajectories from the airlines were evaluated that showed significant benefits to the individual airlines as well as the overall traffic flow. The IDM concept was initiated in the SMART-NAS project, was completed under the ATM-X project, and was developed collaboratively with the FAA and airline partners. Over the course of IDM development, NASA researchers produced 19 conference papers and publications. Outside supporting organizations, funded by IDM, produced 20 additional conference papers and publications, in which they advanced fundamental research on topics such as better stochastic traffic demand prediction, and application of machine learning techniques for modeling traffic management initiatives. Final concept procedures and tool specifications have been transferred to the FAA Air Traffic Organization Operational Concepts, Validation, and Requirements group.

AOSP research is focused to achieve the vision of NextGen including; accommodating projected growth in air traffic while preserving and enhancing safety; providing all airspace system users more flexibility and efficiency in the use of airports, airspace and aircraft; meeting our civil aviation, national defense, and homeland security needs as a national priority; and maintaining pace with a continually evolving scientific and technical environment.
The objectives of AOSP are to:
AOSP is comprised of three projects: Airspace Technology Demonstrations (ATD), Shadow Mode Assessment Using Realistic Technologies for the National Airspace System (SMART-NAS) for Safe Trajectory-Based Operations, and Safe Autonomous System Operations (SASO). The three projects are formulated to make major contributions to air traffic needs of the future through the development and research of foundational concepts and technologies and their analysis, integration, and maturation in relevant, system-level environments. Each of the projects are, much like the airspace system itself, highly integrated and require attention to critical system integration and transition interfaces with the NAS.
This program continues Airspace Systems Program research, and the aircraft state awareness research and system wide safety research that was previously conducted within the Aviation Safety Program. AOSP develops and explores fundamental concepts, algorithms, and technologies to increase throughput and efficiency of the National Airspace System safely. Also, the program provides knowledge, concepts, and methods to the aviation community to manage increasing complexity in the design and operation of vehicles and the air transportation system.
