註釋

Research was conducted to identify and evaluate innovative active warning devices with potential for improving safety at railroad-highway grade crossings. Candidate devices were identified and/or developed, and the most promising devices were evaluated in a detailed laboratory study. Three of the devices were chosen for field evaluation: (1) four-quadrant gates with skirts and flashing light signals; (2) four-quadrant flashing light signals with overhead strobes; and (3) highway traffic signals with white bar strobes in all red lenses. The report documents the methodology and results of the field evaluations, presents a summary of the research leading up to the field evaluations, and presents the results of benefit-cost analyses for the innovative devices and guidelines for their implementation.
