Previous studies indicate that one promising avenue to grade-crossing motorist-warning systems, offering lower cost and independent of railroad-track circuits, is use of a radio-communication link for signal activation. By this means, the presence of a train approaching a crossing can be...
This report describes a computer-aided analytical approach to estimation of the potential benefits, costs, and implementation implications associated with allocation of grade crossing safety resources. Three types of information are required as input: (1) the grade crossing population,...
In response to the Federal Railroad Safety Act of 1970, a joint government/industry effort to compile a national inventory of railroad-highway crossings was initiated in 1972 and completed in 1976. The inventory contains data on the physical and operational characteristics of all 402,000...
Inventory Status as of May 1978. In response to the Federal Railroad Safety Act of 1970, a joint government/industry effort to compile a national inventory of railroad-highway crossings was initiated in 1972 and completed in 1976. The inventory contains data on the physical and operational...
This report discusses the effect on a railroad's legal liability for railroad-highway grade crossing accident costs when that railroad uses innovative grade crossing safety equipment. Its purpose is to evaluate the assertion that a railroad's use of innovative warning device technology increases...
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...
