This document presents techniques tor constructing and evaluating railroad grade crossing hazard indexes. Hazard indexes are objective formulas for comparing or ranking cross1ngs according to relative hazard or for calculating absolute hazard (conditional expected frequency of grade cross1ng...
The study focused on a detailed investigation of all potential train detection techniques which do not use the track. Both point sensing and continuous sensing system approaches were analyzed. It was found that the transmission line sensor and magnetic point sensor offer the greatest likelihood...
The Highway Safety Acts of 1973 and 1976, and the Surface Transportation Assistance Act of 1978, provide funds to individual states to improve safety at public rail-highway crossings. This report was undertaken in support of a U.S. DOT effort to develop a resource allocation model designed to...
This report describes revenue-service tests of locomotive-mounted strobe lights used to make trains more conspicuous to motorists at rail-highway crossings. The testing, conducted in cooperation with four railroads, had the objectives of assuring practicality compatibility with normal operations...
The Highway Safety Acts of 1973 and 1976, and the Surface Transportation Assistance Act of 1978 provide funds to individual states to improve safety at public rail-highway crossings. This report was undertaken in support of a U.S. DOT effort to improve the efficient allocation and use of these...
The purpose of this study was to identify and evaluate potential concepts for reducing injuries to highway occupants and train occupants in rail-highway grade crossing collisions. A review of railroad, highway vehicle, and aviation sources was made. The identified concepts were principally those...
This report describes a methodology developed at the Transportation Systems Center for the Federal Railroad Administration and the Federal Highway Administration to aid in determining the most effective allocation of funds to improve safety at rail-highway crossings. One way to improve safety is...
One important improvement for achieving greater effectiveness in train-activated warning systems at railroad-highway grade crossings (RHGC) would be to provide a constant warning time (CWT) to the motorist of the impending arrival of a train. This report describes an investigation that was...
The Highway Safety Acts of 1973 and 1976, and the Surface Transportation Assistance Act of 1978, provide funding authorizations to individual states to improve safety at public rail-highway crossings. The installation of active motorist warning devices, such as flashing lights or flashing lights...
This report examines five factors affecting the safety impact and costs associated with application of retroreflective materials to railroad freight cars to reduce the number of rail-highway crossing accidents in which motorists run into the side of a train in darkness. Measurements and...
