Available in PDF, EPUB and Kindle. Book excerpt: When accidents happen, drivers are blamed for the mishap. When drivers consistently fail at certain locations, it then becomes obvious that the problem lies not with them, but with the geometry of the road itself. Because accidents are not evenly distributed throughout the road network, locations with high accident rates are a clear indication that there are other factors involved, besides driver error, which are characterized by the road itself. In most countries, two-lane rural roads make up about 90 percent of rural networks and they account for over 60 percent of highway fatalities worldwide, approximately 500,000 people per year. The methodology described in this book will support the achievement of quantified measures of: design consistency; operating speed consistency; and, driving dynamic consistency. The safety criteria are then combined into an overall safety module for a simplified general overview of the safety evaluation process. The authors also encourage the coordination of safety concerns with important economic, environmental and aesthetic considerations. This book will be an invaluable aid to educators, students, consultants, highway engineers and administrators, as well as scientists in the fields of highway design and traffic safety engineering.

Available in PDF, EPUB and Kindle. Book excerpt: National statistics indicate that fatality rates on rural Federal-aid primary highways have been significantly higher compared to those for urban and rural Interstate highways and urban primary highways. Although this group of highways includes two-lane rural roads, an important component of the rural Federal-aid primary highways are multilane rural highways. More than 56 000 km of arterial highways in the United States are multilane, non-Interstate roads in rural areas. Many previous studies have been conducted regarding the safety effects of various traffic and geometric roadway features. The majority of these studies were concentrated on rural two-lane roads. There have also been a few notable studies that investigated roadway crosssection design elements for suburban highways and urban streets. However, there has been limited research on the safety effects of geometric design features on rural, multilane, nonfreeway highways. This study examined the effects of various cross-section-related design elements on accident frequency and developed an accident prediction model for rural, multilane, nonfreeway highways.

Download or read book Highway Design and Traffic Safety Engineering Handbook written by Ruediger Lamm and published by McGraw-Hill Professional Publishing. This book was released on 1999-01-01 with total page 1088 pages. Available in PDF, EPUB and Kindle. Book excerpt: Truly unique, this is the first book to present a thoroughly scientific and practical approach to designing highways for maximum safety. Based on original research plus scrupulously collected data amassed over more two decades in different continents by the main author, this important book originates vital criteria for safe design and shows you how best to achieve roads with the lowest possible accident risk and severity rates. A true must-read for highway engineers and safety officials, Highway Design and Traffic Safety Engineering Handbook provides up-to-date information that is available nowhere else and a complete, practical program for designing the safest possible roadways. The authors, who are noted international authorities on highway safety, give you essential information on sound new designs, design cases to avoid, examples of good and poor solutions, the redesign of existing roads, and far more. In addition, this valuable and necessary resource gives you serious help coordinating safety concerns with important economic, environmental, and aesthetic considerations. The new standard in highway design methods, this book will become a keystone in every highway designer's library.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to establish empirical relationships between truck accidents and highway geometric design. First, statistical frameworks based on Poisson and negative binomial regression models were proposed. Preliminary models were then developed using accidents and road inventory data from the Highway Safety Information System (HSIS). Three roadway classes were considered in the model development: rural Interstate, urban Interstate and freeway, and rural two-lane undivided arterial. The maximum likelihood method was used for estimation of model parameters. Information criterion, asymptotic t-statistic, and goodness-of-fit test statistics were employed to evaluate the estimated models. The model results based on data from one of the HSIS States--Utah, were used for analysis and for suggesting areas in which the quality and quantity of the existing HSIS data can be enhanced to improve the developed models. Despite the limitations in existing Utah data, some encouraging preliminary relationships were developed for horizontal curvature, length of curve, vertical grade, length of grade, shoulder width, number of lanes, and annual average daily traffic (AADT) per lane (a surrogate measure for vehicle flow density).

Available in PDF, EPUB and Kindle. Book excerpt: Expectancy relates to a driver's readiness to respond to situations, events, and information in predictable and successful ways. This report describes the concept of driver expectancy in the context of the driving task, and provides examples of expectancy and expectancy violations. It includes a procedure for identifying general and specific expectancy violations to enable engineers to develop remedial treatments to deal with expectancy problems.

Download or read book Prediction of the Expected Safety Performance of Rural Two lane Highways written by Douglas W. Harwood and published by . This book was released on 2000 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an algorithm for predicting the safety performance of a rural two-lane highway. The accident prediction algorithm consists of base models and accident modification factors for both roadway segments and at-grade intersections on rural two-lane highways. The base models provide an estimate of the safety performance of a roadway or intersection for a set of assumed nominal or base conditions. The accident modification factors adjust the base model predictions to account for the effects on safety for roadway segments of lane width, shoulder width, shoulder type, horizontal curves, grades, driveway density, two-way left-turn lanes, passing lanes, roadside design and the effects on safety for at-grade intersections of skew angle, traffic control, exclusive left- and right-turn lanes, sight distance, and driveways. The accident prediction algorithm is intended for application by highway agencies to estimate the safety performance of an existing or proposed roadway. The algorithm can be used to compare the anticipated safety performance of two or more geometric alternatives for a proposed highway improvement. The accident prediction algorithm includes a calibration procedure that can be used to adapt the predicted results to the safety conditions encountered by any particular highway agency on rural two-lane highways. The algorithm also includes an Empirical Bayes procedure that can be applied to utilize the safety predictions provided by the algorithm together with actual site-specific accident history data.
