Safety of high speed ground transportation systems: Analytical methodology for safety validation of computer controlled subsystems. Volume 2. Development of a safety validation methodology. Final report
The evolution in the implementations of safety critical systems in the railroad industry from simple vital relays to more complex computer-based configurations has raised many issues among users as well as the Federal Railraod Authority (FRA). Foremost among these issues is the need to assure similar or improved levels of safety those currently provided by conventional fail-safe technology. This concern is heightened in newer high-speed rail and maglev systems which operate or are being designed to operate at considerably higher speeds and levels of automation than conventional rail systems. The overall objective of this program was to develop a safety validation methodology that could be considered (by the FRA) for use as a standard for manufacturers and users to help ensure the safe operation of safety critical computer-based system.
