Rapid assessment of air traffic impact of blocking airspaces: Integrated communications navigation and surveillance (ICNS) conference

· Research demonstrated viability of assessing the impact of blocking airspaces, using a “what-if” analysis paradigm · Data reduction technique resulted in efficiency data size and memory management, with negligible loss in accuracy · Traffic projection model performed well, given the uncertainties of traffic pattern · Research results are preliminary, further study to evaluate sensitivity of model performance to constraints such as location, airspace size and closure time are ongoing · Alternate approach to projection based on using a grid to capture traffic is being explored · Assessing additional impact metrics, namely delay and extra distance is being researched.
