OBJECTIVE Direction of injury force inferred from pelvic radiographs may be used in trauma care to predict associated injuries and guide intervention. Our objective was to compare injury direction determined from anteroposterior (AP) pelvic radiographs with injury forces determined from crash site investigation. MATERIALS AND METHODS We studied all 28 subjects from the Crash Injury Research E...

1 This paper provides a comprehensive analysis of roundabout crash patterns. First, an improved 2 method was used to calculate crash type percentages for Wisconsin roundabouts. Second, the 3 crash type patterns were compared between roundabout types and between at-fault driver 4 residency types. It was found that the entering-circulating crash was the severest at single-lane 5 roundabouts while...

This research involves the development of a tool that can be used to assess the changes in traffic safety tendencies that result from changes in traffic flow. The tool uses data from single inductive loop detectors, converting 30-second observations of volume and occupancy for multiple freeway lanes into traffic flow regimes. Each regime has a specific pattern of crash types, which were determi...

Conspicuous cyclic changes in population density characterize many populations of small northern rodents. The extreme crashes in individual number are expected to reduce the amount of genetic variation within a population during the crash phases of the population cycle. By long-term monitoring of a bank vole (Myodes glareolus) population, we show that despite the substantial and repetitive cras...

This study investigates financial contagion among seven international stock markets around the October 19, 1987 crash. Building on a recent advance in vector autoregression analysis by [Swanson, N., Granger, C.W.J., 1997. Impulse response functions based on a causal approach to residual orthogonalization in vector autoregression. Journal of the American Statistical Association 92, 357–367], dat...

traffic events account for about 1,200,000 deaths and more than 50 million injuries annually across the world. research shows that male drivers make up the majority of those who sustain injuries in car accidents. the present research aims to compare psychological factors affecting driving-related crashes of male and female drivers. accordingly, the sample data is collected from 208 crash-involv...

In traffic safety literature, crash frequency variables are analyzed using univariate count models or multivariate count models. In this study, we propose an alternative approach to modeling multiple crash frequency dependent variables. Instead of modeling the frequency of crashes we propose to analyze the proportion of crashes by vehicle type. A flexible mixed multinomial logit fractional spli...

Research has noted a ‘pronounced pattern of increase with increasing remoteness' of death rates in road crashes [1]. However, crash characteristics by remoteness are not commonly or consistently reported, with definitions of rural and urban often relying on proxy representations such as prevailing speed limit. The current paper seeks to evaluate the efficacy of the Accessibility / Remoteness In...

A firm is called to have stock price crash risk if the firm has a tendency to experience a sudden drop in its stock price. In this study, the relation between the firm-level of business strategy and future stock price crash risk Is examined, as well as the effect of stock overvaluation on the relationship between business strategy and crash risk investigated. Using the strategy index and crash ...
