Abstract:

This document includes a general review of innovative conceptual and technical approaches to train-activated motorist learning systems for use at railroad-highway grade crossings, and also contains a specific report describing a study directed toward the generation, analysis and evaluation of innovative concepts.  The review includes a discussion of communication-link systems, radar train detection, locomotive-mounted transmitters, and several other concepts.  The basic application constraints of safety, reliability, resistance to service environments and low cost are used as the basis for evaluating the merits of the alternative concepts.

The special study here explores the communication-link concept in detail, with particular emphasis on train-detection techniques.  The use of microprocessor technology is advocated, along with substantial changes in motorist warnings.
