• Abstract:
  The purpose of this project is to investigate alternative ways to improve the visibility and conspicuity of flashing signal lights at about 54,400 railroad-highway crossings with flashing lights or flashing lights and gates. This purpose is transposed into a scope of work by means of the following objectives: 1) To analyze and evaluate current signal specifications, practice, and equipment, and to document their evolution and bases; 2) To develop performance specifications for improved signal light dispersion and intensity; 3) To develop, analyze and evaluate various alternative methods of obtaining improved light dispersion and intensity, within the existing railroad-highway crossing signal system, in order to improve the visibility and conspicuity of the signals; 4) To determine the hardware modifications or accessories needed to improve the visibility of existing signals; and 5) To construct and test a prototype of the proposed modification. A presentation of this study's findings, technical details, tables and figures which support related documentation and conclusions are included in this volume. This volume is the second in a series of three. The others are an Executive Summary and Volume II: Data and Appendix.
