Alternating Yellow and Green Taxiway Centerline as a Runway Safety Enhancement.

摘要

This research effort was conducted to investigate and validate the suitability of installing alternating yellow and green taxiway centerline lights on taxiway segments located between the runway hold position marking and the runway centerline in the direction approaching the runway. This lighting configuration would serve as a visual cue to pilots and vehicle drivers that they are about to enter the runway environment/runway safety area (RSA). The objective of this research effort was to determine how the proposed lighting configuration would appear to pilots approaching the hold line (runway environment/RSA), if presently available lighting fixtures are adequate for the purpose, if present spacing standards are adequate for the purpose, if pilots interpret the purpose of the alternating yellow and green taxiway centerline lighting configuration correctly, and the cost factors involved in making such a change. Having considered all of the data and information gathered during this evaluation effort, illuminating the runway environment/RSA area with alternating yellow and green taxiway centerline fixtures was found to be a cost-efficient, easy to deploy tool that will assist in reducing runway incursions at those airports that have existing taxiway centerline lights.
