The Federal Railroad Administration (FRA) has undertaken a rulemaking process to address the use of locomotive horns at public highway-railroad grade crossings [1]. This rule includes a provision to regulate the sound level output of railroad horns. This letter report supports the rulemaking by...
Five technologies were evaluated for their ability to detect trains and/or highway vehicles approaching and occupying highway railroad intersections. Tests were conducted on the performance of these technologies during October and November 1999 at the Federal Railroad Administration's...
The use of light emitting diode (LED) warning signals in the railroad industry has increased due to recent technological improvements. LED signals have many potential benefits over traditional incandescent signals, including longer life, increased durability, and lower power consumption. Safety...
Safety: Older Drivers; Traffic Law Enforcement; Management; School Transportation; Emergency Evacuation; Truck and Bus; and Motorcycles The 2005 series consists of approximately 770 papers selected from 2,600 submissions after rigorous peer review. The peer review for each paper published is...
Drivers and transportation experts assessed the brightness, durability, and adhesiveness of retroreflective materials designed to improve the detectability of rail cars.
The U.S. Department of Transportation’s Volpe National Transportation Systems Center, under the direction of the Federal Railroad Administration, conducted a 3-year demonstration of an automated prototype railroad infrastructure security system on a railroad bridge. Specifically, this commercial...
This document provides guidance recommendations and supporting material to assist designers and implementer s of intelligent transportation system (ITS) applications related to highway-rail intersections (HRI). The guidance focuses specifically on roadway user human factors requirements...
This report provides an update on the state-of-the-art technologies with intrusion and obstacle detection capabilities for rail rights of way (ROW) and crossings. A workshop entitled Intruder and Obstacle Detection Systems (IODS) for Railroads Requirements was held in 1998, and the Volpe...
This technical report documents the development of a set of human factors guidelines to aid designers and implementers of intelligent transportation systems (ITS) at highway-rail intersections (HRIs). The focus was specifically on roadway user human factors issues. In addition to providing...
Under sponsorship from the U.S. Department of Transportation Federal Railroad Administration, Office of Research and Development, the John A. Volpe National Transportation Systems Center performed an evaluation of the four-quadrant gate/obstruction detection system at the School Street crossing...
