The Federal Railroad Administration (FRA) was created by the Department ofTransportation Act of 1966. It is one of ten agencies within the U.S. Department ofTransportation concerned with intermodal transportation. FRA promotes safe,environmentally sound, successful railroad transportation to meet the needs of all customers today and tomorrow.
FRA's Office of Railroad Safety promotes and regulates safety throughout the Nation's railroad industry. The office executes its regulatory and inspection responsibilities through a diverse staff of railroad safety experts.
The Federal Railroad Administration is responsible for working with stakeholders to develop cohesive goals and policies for maintaining and improving the U.S. freight and passenger rail networks. This section covers various efforts across America and the world in helping to deliver safe, reliable, and efficient rail transportation.
FRA Research & Development (R&D) projects contribute to the FRA's safety regulatory processes, to railroad suppliers, to railroads involved in the transportation of freight, intercity passengers, commuters, and to railroad employees and their labor organizations.
In this section, we provide descriptions and comprehensive, official sources for FRA's regulations (also called rules), selected legislation, as well as policy and guidance documents. Additionally, you will find current topics of high interest or significant impact to Congress, railroads, employees, labor, public interest groups and other stakeholders.
FRA supports passenger and freight railroading through a variety of competitive grant, dedicated grant, and loan programs to develop safety improvements, relieve congestion, and encourage the expansion and upgrade of passenger and freight rail infrastructure and services. FRA also provides training and technical assistance to grantees and stakeholders.
Analysis of the Safety Impact of Train Horn Bans at Rail-Highway Grade Crossings: An Update Using 1997-2001 Data
AUTHOR: FRA, Westat OFFICE: RRS REPORT NUMBER: Contract No. DTFR53-03-P-00005 SUBJECT: Highway-Rail Grade Crossings, USDOT National Highway-Rail Crossing Inventory KEYWORDS: Train Horn Rule and Quiet Zones ABSTRACT: This report updates Westat's prior report to FRA (Zador, 2002) in terms of both data and statistical methods. Safety impact estimates in the prior report were based on 5-year accident data for 1992-1996. In this report, safety impact estimates are based on recent grade-crossing accidents during the 5-year period between 1997 and 2001. As in the prior report, this report also derives safety impact estimates by comparing observed accident frequencies to expected accident frequencies.
In the prior report, FRA's methods (U.S. DOT, FRA, 1987; U. S. DOT, FRA, 2000) were used, in a slightly modified form, to estimate the expected accident frequency at each grade crossing from the grade crossing's physical and operating characteristics. In Step 1 of this three step procedure, FRA's basic accident prediction formula (without adjustment for recent local accident history, U.S. DOT, FRA, 1987) was used to predict expected accidents. In Step 2, grade crossings were grouped on predicted accident risk into 10 groups with roughly comparable accident risks. In Step 3, general linear models (GLM, see McCullaghand Nelder, 1989) were used to estimate overall percent difference (across all risk groups but by warning device class) between grade crossings in the same accident risk group with and without the ban.
