LED-Enhanced Sign Research to Reduce Vehicle Queuing at Highway-Rail Grade Crossings

Researchers studied the effectiveness of an integrated laser-triggered queue detection system/light-emitting-diode (LED)-enhanced “DO NOT STOP ON TRACKS” sign as compared to a baseline version with no lights. Testing was conducted at the Jay Street grade crossing on the Metro-North Railroad in the Village of Katonah, NY. The results of a before-and-after study showed that the number of vehicles stopped in the zonal area of the grade crossing decreased by 26.6 percent from the baseline to the post-installation configurations. A controlled testing program is recommended before a recommendation for wider use can be made.
