Abstract:

This report describes the results of a study directed toward the generation, analysis and evaluation of innovative conceptual and technical approaches to train-activated motorist warning systems for use at railroad-highway grade crossings.  Particular attention is given to the use of the track as a transmission line in a guided reflection (radar-like) technique operating at audio frequencies.  Attention is also given to improve special road surfaces in advance of the crossing, and to optically programmed traffic lights.
