Available in PDF, EPUB and Kindle. Book excerpt: This study developed a new, better procedure for assessing widespread geographic effects resulting from the use of safety treatments. Most currently used statistical methods for countermeasure evaluation assess the spot or local changes that result from the new treatment. The effects of the treatment on the entire system or near-by contiguous links are seldom evaluated. The new approach is ideal for applications where large quantities of data reside in a PC computer format. Incorporated in the methodology are known procedures for determining if regression-to-the-mean (RTM) problems exist and how those problems can be minimized when they are present. A previous research study developed a computer program - Bayesian Estimation of Accidents in Transportation Studies (BEATS) - that identifies and corrects RTM bias in highway safety studies. Step-by-step guidelines were developed on how to plan and use the new procedure to evaluate highway safety studies. The guidelines describe what are adequate sample sizes, how to identify RTM problems, and how computerized data analysis procedures can be used.

Book Synopsis System-wide Safety Improvements by : Benjamin V. Chatfield
Download or read book System-wide Safety Improvements written by Benjamin V. Chatfield and published by . This book was released on 1987 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to safety engineers, highway planners, and others concerned with the procedures used by states to plan and program safety improvements. Information is presented on current practice of states in using system-wide improvements to provide safety consistency. The primary purpose of system-wide safety improvements is to increase safety by improving roadway consistency - to minimize violations of driver expectancy and to avoid or reduce injury and damage that occur when a vehicle leaves the roadway. This report of the Transportation Research Board describes the system-wide and spot approaches to safety improvement, explains strategies and programs for system-wide improvements, and gives general guidelines for a program of improving roadway consistency through system-wide safety improvements.

Available in PDF, EPUB and Kindle. Book excerpt: PennDOT engaged Gannett Fleming to conduct research into best practices in the use of geospatial analysis tools for highway safety analyses. The goals of the effort were to define a methodology for PennDOT to follow in identifying the best candidate locations for highway safety improvements, and to develop a Proof of Concept to test the proposed methodology. After conducting interviews and workshops involving more than 35 of PennDOT's stakeholders in highway safety processes, Gannett Fleming interviewed highway safety managers in five other state and federal highway agencies to determine what innovative tools and practices are currently being used. Gannett Fleming's research also included a review of literature related to the study from more than 80 sources. Based on Gannett Fleming's research and analysis, PennDOT selected the "Highway Safety Data Relationships Knowledge Base" for further research. The knowledge base is an information repository based on concepts in data mining and expert systems. It uses advanced statistical analysis methods and expert business knowledge rules to discover data patterns based on correlation and other forms of relationships in the data. The knowledge base can be applied to diagnosing specific combinations of data attributes and features that may indicate the causative factors among homogeneous populations of crashes. Most highway safety data analyses involve studying correlations among multiple data sets. The knowledge base is an innovative and compreh3nsive tool for such an application. It provides a framework for identifying and managing relationships among many combinations of data sets that are useful in highway safety analyses. Gannett Fleming proceeded to develop a prototype as a proof of concept. Gannett Fleming demonstrated the prototype using actual PennDOT crash data. Three analysis scenarios were demonstrated" evaluating safety programming alternatives for alcohol involved crashes, diagnosing data patterns of crashes at a selected highway location, identifying potential sites for system-wide deployment of a selected countermeasure
