Abstract The objective of this research is to characterize large truck safety levels in Texas on the basis of driver, vehicle, cargo, and carrier traits while controlling for the effects of crash and operating environment conditions. Data to support this investi...

While a core dump carries a large amount of information, it barely serves as informative debugging aids in locating software faults because it carries information that indicates only a partial chronology of how program reached a crash site. Recently, this situation has been significantly improved. With the emergence of hardwareassisted processor tracing, software developers and security analyst...

Crash reporting systems are useful tools that allow users to report system failures, subsequently contacting the appropriate support group for resolution. As a software system grows and becomes more versatile, the number of crashes increases. A large software company receives typically thousands of crashes a day, which make it difficult for software engineers to address these reports in a timel...

INTRODUCTION In spite of recent advances in traffic surveillance technology and ever-growing concern over traffic safety, there have been very few research efforts establishing links between real-time traffic flow parameters and crash occurrence. This study aims at identifying patterns in the freeway loop detector data that potentially precede traffic crashes. METHOD The proposed solution ess...

Crash-only component has PWR switch: stop=crash clean shutdown loss of power kernel panic cure transient failure Only one way to go down only one way to come up: start = recover Each component must has a PWR switch uniform behavior Crash-only system = assembly of crash-only components; system PWR switch implemented in terms of components' switches PWR switch is external, does not invoke compone...

Abstract The sudden impact during a collision of an automobile may cost the life passengers. Several researchers are working to design materials and structures which can absorb impact-energy before passing it One such solution is crash-box-structure placed primarily on frontal side, in-between bumper main part automobile. crash-box-structure’s ability energy influenced by its deformation-proper...

Millions of cars on the road today have Event Data Recorders (EDRs). A small percentage of cars currently have EDR data downloaded, typically hours or days after a motor vehicle crash (MVC). However, real time use of EDR data at the crash scene has the potential to save lives by providing additional quantitative information to emergency medical services (EMS) personnel in order to enhance the d...

The Challenger crash was a highly visible event whose underlying cause was not publicly revealed until much later. Methodologically, the event has appealing features. It was an exogenous occurrence. There was no leakage that induced run-up or run-down in the pre-event period. Our basic analysis provides a test of market efficiency. How quickly and accurately did the stock market process the imp...

Evaluations of crash protection safety features require measures for quantifying impact severity. Velocity change (delta-V) is the major descriptor of collision severity used in most real-world crash databases. One of the limitations of delta-V is that it does not account for the time over which the crash pulse occurs (delta-t). Late model GM vehicles equipped with event data recorders capture ...

Currently, mainly aggregated statistics are used for bicycle crash risk calculations. Thus, the understanding of spatial patterns at local scale levels remains vague. Using an agent-based flow model and a bicycle crash database covering 10 continuous years of observation allows us to calculate and map the crash risk on various spatial scales for the city of Salzburg (Austria). In doing so, we d...
