4 This work investigates the properties of crash reports collected from Ubuntu Linux users. Understanding crash reports is important to better store, categorize, prioritize, parse, triage, assign bugs to, and potentially synthesize them. Understanding what is in a crash report, and how the metadata and stack traces in crash reports vary will help solve, debug, and prevent the causes of crashes....

More researchers started using real-time traffic surveillance data, collected from loop/radar detectors (LDs), for proactive crash risk assessment. However, there is a lack of prior studies that investigated the link between real-time traffic data and crash risk of reduced visibility related (VR) crashes. Two issues that have not explicitly been addressed in prior studies are; (1) the possibili...

OBJECTIVE This study aims to quantify and describe the burden of fatal pedestrian crashes among persons using wheelchairs in the USA from 2006 to 2012. DESIGN The occurrence of fatal pedestrian crashes among pedestrians using wheelchairs was assessed using two-source capture-recapture. Descriptive analysis of fatal crashes was conducted using customary approaches. SETTING Two registries wer...

22 n 1997 North Carolina was one of the first two states in the nation to adopt a Graduated Driver Licensing system (GDL) to reduce motor vehicle crashes among young novice drivers. This policy was driven heavily by scientific research. At that time, motor vehicle crashes were the leading cause of death among teenagers. The adoption of GDL led to a sharp decline in teenage driver crashes and a ...

This work analyzes patterns and factors in workzone crashes. In response to actual and suspected deficiencies in the quality of workzone crash reporting from standard police crash reports, an enhanced crash report form and procedure was developed and applied by police agencies in a small sample of workzones in Illinois. Analysis of 110 workzone crashes revealed differences between what the poli...

A brief historical perspective is first given concerning financial crashes, from the 17th till the 20th century. In modern times, it seems that log periodic oscillations are found before crashes in several financial indices. The same is found in sand pile avalanches on Sierpinski gaskets. A discussion pertains to the after shock period with illustrations from the DAX index. The factual financia...

The experiences in many countries document that alcohol is involved in a substantial fraction of traffic crashes, and particularly crashes involving fatalities. In the USA a national surveillance system is now in place which provides information on all traffic crashes involving one or more fatal events. Data from this Fatal Accident Reporting System for the years 1977 through 1981 have been ana...

This article explores an interplay between process crash failures and concurrency. Namely, it aims at answering the question, “Is possible to cope with more when some number of crashes occur before predefined contention point happened?”. These are named λ-constrained crashes, where λ is (known by processes). Hence, this considers two types crashes: classical (which can any time consequently cal...

OBJECTIVE This analysis tested whether comprehensive community interventions that focus on reducing alcohol availability and increasing substance abuse treatment can reduce alcohol related fatal traffic crashes. INTERVENTION Five of 14 communities awarded Fighting Back grants by The Robert Wood Johnson Foundation to reduce substance abuse and related problems attempted to reduce availability ...

Highway work zones constitute a major safety concern for government agencies, legislatures, the highway industry, and the traveling public. Each year, hundreds of people lose their lives and many more are injured due to vehicle crashes in work zones on the national highway system. Over the years, temporary traffic control (TCC) measures have been developed to improve the safety in work zones. T...
