NCUTCD Proposed Revisions to Part 8 of the MUTCD
The National Committee on Uniform Traffic Control Devices (NCUTCD) has approved proposed revisions to Part 8 Ė Traffic Control for Railroad and Light Rail Transit Grade Crossings, of the Manual on Uniform Traffic Control Devices (MUTCD). These proposed revisions to the MUTCD have been approved by the NCUTCD, but have not been approved by the Federal Highway Administration (FHWA). After review and possible modification by the FHWA, these proposed revisions are expected to be published as a Notice of Proposed Amendments to the MUTCD. After receiving comments from the public, the FHWA will then publish a final version of these revisions in the next edition of the MUTCD. It is very likely that the final version will include some changes to these proposed revisions, however these recommendations are in the public record and may be useful to practitioners in the absence of a new Manual.
Preemption Language (aproved in June 2015):
Edge Line and Stop Line Markings Language (approved in January 2016):
Pre-Signals are traffic signals in advance of the highway rail grade crossings. This article from the ITE Journal, "Use of Pre-Signals in Advance of a Highway Rail Grade Crossing: A Specialized Tool with Specific Applications", provides a great description of pre-signal use in the United States.
Hazard Index Calculations
The Federal Railroad Administration provides an online application for determining the hazard index of an at-grade crossing. Follow the link below to use the application.
Sample Diagnostic Team Evaluation Reports
Diagnostic Team Evaluations of grade crossings are an important part of evaluating the safety of at-grade crossings. Here is a link to the State of Nevada Department of Transportation Diagnostic Review Form.
Comprehensive Costs of Highway-Rail Grade Crossing Crashes
TRBís National Cooperative Highway Research Program (NCHRP) Report 755: Comprehensive Costs of Highway-Rail Grade Crossing Crashes describes a process for estimating the costs of highway-rail grade crossing crashes. A spreadsheet-based tool to facilitate use of the cost estimation process is available online.
