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).

Book excerpt: Principal findings of this study were that geometrics alone account for only a small portion of the variance in accidents and that no relationship could be established between fatalities and the geometrics studied. The geometrics studied include several types of interchanges, paved shoulders, sight distance, delineators, surface types, and other variables. Mathematical models were developed which can provide estimates of the average number of accidents on a particular type of highway or interchange, using the appropriate variables.

This book was released on 2016-09-12 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are approximately 4,000 fatalities in crashes involving trucks and buses in the United States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these crashes might have involved fatigued drivers. The stresses associated with their particular jobs (irregular schedules, etc.) and the lifestyle that many truck and bus drivers lead, puts them at substantial risk for insufficient sleep and for developing short- and long-term health problems. Commercial Motor Vehicle Driver Fatigue, Long-Term Health and Highway Safety assesses the state of knowledge about the relationship of such factors as hours of driving, hours on duty, and periods of rest to the fatigue experienced by truck and bus drivers while driving and the implications for the safe operation of their vehicles. This report evaluates the relationship of these factors to drivers' health over the longer term, and identifies improvements in data and research methods that can lead to better understanding in both areas.

This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: In March 1988, an international workshop on intersections without traffic signals was held at the Ruhr-University in Bochum, Germany. The proceedings of this workshop were published by Springer 1). The workshop was performed in a very harmonious atmosphere, which stimulated the experts from different countries to communicate and exchange their ideas and experiences. The presentations and the written contributions documented the present state of technical solutions for design and engineering of unsi gnalized intersections both regarding scientific research and practical applications. Moreover, numerous unsolved problems were identified. Thus, the 1988 workshop stimulated new developments in the field of unsignalized inter sections in several countries. In the meantime, these investigations have lead to a remarkable progress. For example in Germany a new guideline for unsignalized cross intersections and T-junctions has been finished and is going to be introduced in 1991. New results on roundabout capacity have been worked out as well. Many particularly important developments were made in foreign countries. Especially in the United States, an increasing interest in this subject can be observed. In the annual meetings of the TRB, this item received great attention. Many research institutes in North America have concentrated their activities on that point. A new TRB-circular concerning unsignalized intersections is going to be published. It will contain a new procedure for four-way-stop-control intersections, which seems to be a special feature of North American traffic engineering. However, new results from the US for two-way-stop control intersections are available as well.
