Languages : en
Pages : 117
Book Description
TRB's Transportation Research Record: Journal of the Transportation Research Board, No. 2241 consists of 13 papers that explore highway safety metrics implementation and evaluation, levels of safety at freeway exits, calibration of Highway Safety Manual predictive models, estimating crash modification factors for daytime versus nighttime work zones, and an evaluation of the Texas Department of Transportation safety improvement index as a prioritization tool. This issue of the TRR also examines the effects of underreporting crash data, crash variances estimated by poison models, modeling of driver decision at onset of yellow light at signalized intersections, roundabout performance, automated detection of spatial traffic violations, identifying and quantifying intersection obstruction and its severity, and workplace simulator for geometric design of rural roads.
Statistical Methods in Highway Safety Analysis

Pages : 88
Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 295: Statistical Methods in Highway Safety Analysis focus on the type of safety analysis required to support traditional engineering functions, such as the identification of hazardous locations and the development and evaluation of countermeasures. Analyses related specifically to driver and vehicle safety are not covered, but some statistical methods used in these areas are of relevance and are summarized where appropriate.

Book Description
Highway Safety Analytics and Modeling comprehensively covers the key elements needed to make effective transportation engineering and policy decisions based on highway safety data analysis in a single. reference. The book includes all aspects of the decision-making process, from collecting and assembling data to developing models and evaluating analysis results. It discusses the challenges of working with crash and naturalistic data, identifies problems and proposes well-researched methods to solve them. Finally, the book examines the nuances associated with safety data analysis and shows how to best use the information to develop countermeasures, policies, and programs to reduce the frequency and severity of traffic crashes. Complements the Highway Safety Manual by the American Association of State Highway and Transportation Officials Provides examples and case studies for most models and methods Includes learning aids such as online data, examples and solutions to problems

Book Description
The Federal Highway Administration Development of Crash Modification Factors (DCMF) Program was established in 2012 to address highway safety research needs for evaluating new and innovative safety strategies (improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes. A goal of the DCMF is to advance highway safety and related research by establishing a sound foundation for the development of highway transportation specific statistical methodologies in cooperation with the American Statistical Association and other statistician communities. In pursuit of that goal, a two-day Technical Experts meeting brought together researchers from the road safety, statistics, and other statistics-related fields such as epidemiology, biostatistics, and agent based modeling that have methodologies relevant to highway safety research applications. The meeting resulted in guidance and materials that supported the development of this white paper, which identifies and discusses opportunities for advancing methodologies to estimate crash modification factors and safety performance functions. The paper outlines considerations and future steps to encourage researchers to explore these techniques in their research.
