Abstract : Five lighting systems proposed for improved other-vehicle operator approach warning - alerting were evaluated in a simulated grade crossing decision paradigm. Additional evaluations were conducted on system conspicuousness. The systems, a Bicolor Radial Beacon, Slow-rate Strobe 2.5 flash per second (FPS), Fast-rate Strobe 1 FPS, truck clearance lights, and side mounted Flourescent Panels, were examined at 10, 20, 30 miles per hour under daylight and night conditions. Some advantage was found for the strobe systems and for the clearance lights as compared to the usual fixed locomotive headlight. Recommendations for further research were made. (Author)
