Available in PDF, EPUB and Kindle. Book excerpt: This research provides a methodology for identifying high risk railway grade crossings (or black spots) in Canada. Black spots are crossings where the expected number of collisions and/or consequences exceeds some pre-set threshold. Two types of collision frequency models are developed & evaluated: a single model with warning device as an independent variable, and three separate models for the three types of warning devices (crossings with signs, flashing lights, and/or gates). For each type of model, Poisson, negative binomial, and empirical Bayesian distributions were investigated for their appropriateness to represent the variation in the observed collisions. A combined consequence score is introduced to represent the total equivalent consequence that may result from a collision at a grade crossing. A two-dimensional graphical approach is adopted for comparing risk at individual crossings on the basis of their expected collision frequency & expected consequence score. The risk graph is used to identify black spots based on a given percentage threshold value.

Download or read book Highway rail Grade Crossing Surfaces written by Hoy A. Richards and published by Transportation Research Board. This book was released on 1998 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state and local highway personnel who are responsible for the design, construction, and maintenance of road surfaces and to railroad personnel with similar responsibilities associated with highway-rail grade crossings. It will also be of interest to manufacturers and suppliers of pavement and track materials for crossings. It presents information on the current practices related to highway-rail grade crossing surfaces, including the design and selection of crossing surface materials. This report of the Transportation Research Board describes the various types of highway- rail crossing surfaces, and the issues related to design, operation, and maintenance. Design elements include intersection geometry; drainage; special users, such as bicyclists; and descriptions of failures and their causes. Information is presented on crossing material selection factors, including life-cycle costs and on state practices in selection. Funding issues are also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The last report to Congress on rail-highway crossing safety was in 1971-72. Since then, several actions and changes have occurred. These are discussed in the Executive Summary which is included in this report. This discussion is followed by 8 chapters. The final chapter summarizes the findings of this study on each of nine identified issues, as well as other issues identified during the course of the study.

Book excerpt: "The Highway Safety Manual (HSM) is a resource that provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. The focus of the HSM is to provide quantitative information for decision making. The HSM assembles currently available information and methodologies on measuring, estimating and evaluating roadways in terms of crash frequency (number of crashes per year) and crash severity (level of injuries due to crashes). The HSM presents tools and methodologies for consideration of 'safety' across the range of highway activities: planning, programming, project development, construction, operations, and maintenance. The purpose of this is to convey present knowledge regarding highway safety information for use by a broad array of transportation professionals"--p. xxiii, vol. 1.

Download or read book Railroad Grade Crossing Micro level Safety and Risk Analysis Phase 2 evaluation of Safety Risk at Highway Rail Grade Crossings written by Jacob Mathew (Writer on highway-railroad grade crossings) and published by . This book was released on 2018 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Railroad grade crossings are potential conflict points and pose a risk for all travelers. The degree of the risk depends on many factors such as volume train, volume of vehicles, speed of trains and vehicles, geometry of the crossing, etc. To assess the safety and risk of RR crossings, one may utilize aggregated data for the entire state or the country. Even though analysis of the aggregated data may be useful in establishing correlation among important variables, it might not be very useful for assessing the safety and risk for a given RR crossing. It is proposed to conduct a micro-level analysis to determine the risk of crashes at a given location (or a set of similar locations). The crash risk at a given crossing may depend on past crash history at that location, as well as the relation amount different elements that affect traffic safety at RR crossings. At the micro-level analysis one considers the uniqueness of each crossing and develops a risk factor for such crossings. Then, the safety and risk at system level is determined based on these individual safety and risk assessments. Phase one of this study is near completion and phase two will focus on safety and risk of accident at railroad crossing."--

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Department of Transportation (US DOT) provides funding to state DOTs to implement highway-rail grade crossing improvement programs. These programs are suspected to develop particular safety improvement actions in order to decrease the number of accidents at highway-rail grade crossings. The current work is directed to consider various hazard index/accident prediction methodologies, carefully investigate hazard index/accident prediction methods, applied by Tennessee Department of Transportation (TDOT), develop a model to allocate available monetary resources for upgrades of highway-rail grade crossings in the State of Tennessee and maximize the total benefits in terms of accident and severity reduction. Two different approaches are proposed and a number of numerical experiments are presented to evaluate each approach.
