The authors used a high fidelity, human-in-the-loop simulation in two experiments examining the concept of the New York Integrated Control Complex (NYICC). The first experiment examined the potential effects of collocation alone and collocation with expanded terminal separation standards on the arrival traffic flow into Newark. The second experiment examined the same effects on the departure traffic flows primarily from Newark International (EWR) and LaGuardia (LGA) airports. Each experiment compared three different conditions. In the Normal condition, the participants controlled traffic as they normally would, and a removable wall physically separated the terminal and en route sectors. During the Collocated condition, experimenters removed the wall, and the participants could engage in face-to-face communication and look at each other’s radar displays. During the Terminalized condition, we collocated the sectors and reduced the separation standard for one or both en route sectors from 5 nm to 3 nm. We collected measures throughout the experiments including system performance, subjective ratings of workload, subject matter expert ratings of performance, communication behaviors, and participant opinion. Overall, both experiments provided support for the NYICC concept of operations.
