Collision course? The North Airfield Safety Study at Los Angeles International Airport (LAX)

摘要

The LAX North Airfield Safety Study was undertaken by an Academic Panel consisting of the present authors, and was based in large part on a simulation that was conducted at FutureFlight Central at NASA Ames Research Center. The primary aim of the study was "to estimate as specifically as possible the level of future safety associated with several geometrical configurations of the LAX North Airfield." This paper describes the study, and how it combined information from human-in-the-loop simulations at NASA with historical data from LAX and other US airports about runway incursions and collisions. The analysis indicated that, even under its existing physical layout, LAX North would experience very low risk of runway collisions at traffic levels projected for 2020. That risk could be reduced by about half if the North Airfield runways were reconfigured, and some reconfigurations would also add appreciably to the operational efficiency of the airport. But because the "baseline" level of risk is so low, the Study concluded that "it would be difficult to construct a compelling case on safety grounds alone for reconfiguring the North Airfield.
