Book Synopsis Traffic and Geometric Characteristics Affecting the Involvement of Large Trucks in Accidents by : Nicholas J. Garber
Download or read book Traffic and Geometric Characteristics Affecting the Involvement of Large Trucks in Accidents written by Nicholas J. Garber and published by . This book was released on 1989 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent trends indicate that vehicle miles traveled for large trucks is increasing at a higher rate than for other vehicles. The resulting competition between large trucks and other vehicles for highway space can be expected to result in more multi-vehicle collisions involving large trucks. The likelihood of these collisions causing severe injuries to vehicle occupants will also increase with the trend towards the use of smaller automobiles and heavier and larger trucks. In order to develop countermeasures that will alleviate this problem, it is first necessary to identify the characteristics of large-truck accidents and the role of traffic and geometric variables in such accidents ents. The major factors associated with large-truck accidents including the effect of highway facility type and highway geometry are investigated. Changes in large-truck accidents for periods before and after 1982 are evaluated by a comparison of pre- and post-1982 accident involvement rates. Factors that might have affected large-truck travel and accident rates include the Surface Transportation Assistance Act of 1982 (STAA), the improvement of the nation's economy, and deregulation of the trucking industry. The results indicate that fatal crashes involving large trucks have been increasing in contrast to all other vehicles, for which the fatality rates are constant for the same period. Driver-related factors are associated with 75 percent of all accidents involving trucks, and driver error is associated with SO percent of all fatal truck accidents. A significant correlation is also observed between driver error and highway alignment in accidents involving trucks. The risk of a fatality in a multi-vehicle accident involving a truck and another vehicle is found LO be highest on two-way undivided facilities. On divided, limited access facilities, this risk is reduced by 50 percent. An unexpected increase in tractor trailer accident involvement rates for non-STAA primary routes is observed and is attributed to incompatibilities between large-truck characteristics and the non-STAA highway environment. This interim report presents the results of the first part of a study, which also involves the development of models relating accident occurrence with geometric and traffic characteristics. The development of these models is now in progress. These models and the information given in this interim report will facilitate the formulation of countermeasures that will reduce accidents involving large trucks in Virginia.

Book excerpt: Recent trends indicate that vehicle miles traveled for large trucks is increasing at a higher rate than for other vehicles.

In order to develop countermeasures that will alleviate this problem, it is first necessary to identify the characteristics of large-truck accidents and the role of traffic and geometric variables in such accidents. This study investigated the major factors associated with large truck accidents including the effect of highway facility type and highway geometry, and the development of mathematical models relating the factors with accident rates and probability of occurrence. This first volume documents the methodology of the study, the results of a statistical analysis of large-trucks historical accident data, the results of a fault tree analysis. This second volume gives a detailed description of the development of the regression and logistic models.

Book Synopsis Accident and Traffic Operations Implications of Large Trucks by : Margaret Forsythe
Download or read book Accident and Traffic Operations Implications of Large Trucks written by Margaret Forsythe and published by . This book was released on 1978 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall safety and traffic operations implications of larger trucks are not clear-cut. While several techniques permit the evaluation of the impact of larger trucks on transportation costs and highway costs: (1) accident frequency and severity as a function of vehicle size of weight, and (2) data relating truck size and weight, to highway geometry and traffic operations, at a national level are virtually nonexistent. Prior to the development of a work plan for the collection of empirical truck-related data at a series of sties across the United States, a review of existing literature was performed. The material has been organized into three major subcategories. 1: Truck exposure characteristics (registration and mileage), 2: Truck accident characteristics, 3: Truck traffic operations characteristics. Although accident data is available for interstate motor carriers, there is no national accident data, truck exposure data, or truck performance data (speed, delay, acceleration noise and other such traffic stream behavior measures) that have been collected utilizing both a common truck subpopulation classification scheme and roadway typology utilizing urban/rural, interstate/primary/secondary, descriptors.

Download or read book Analysis and Modeling of Relationships Between Accidents and the Geometric and Traffic Characteristics of the Interstate System written by Julie Anna Fee and published by . This book was released on 1969 with total page 108 pages. Available in PDF, EPUB and Kindle. 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.
