OBJECTIVES The objective of the current study was to quantify the effects of the strength of US state graduated driver licensing laws and specific licensing components on the rate of teenage driver fatal crash involvements per 100,000 teenagers during 1996-2007. The strengths of state laws were rated good, fair, marginal, or poor based on a system developed previously by the Insurance Institute...

Overall comparisons of crash rates based on mileage indicate that truck crash rates are lower than car crash rates, but that truck crashes are more severe. In 1978 the overall U.S. crash rate for cars was estimated at 8.2 accidents per million vehicle-miles of travel; for large trucks (including combinations) the rate was 4.7 per million vehicle-miles, and for combination trucks (e.g., tractor-...

This paper presents a driver performance map of braking and steering in response to three driving scenarios that lead to rear-end crashes. This map encompasses low risk, conflict, near-crash, and crash imminent driving states that correspond to advisory warning, crash imminent warning, and crash mitigation functionalities for intelligent vehicle rear-end crash countermeasures. Specifically, thi...

This paper examines the relationship between the stock crash risk of REITs and different types of institutional investors. First, when we classify REIT institutional investors by their legal type, we find that the ownership of pension funds (bank trusts) is negatively (positively) related to REIT crash risk. In addition, the trading of investment companies, including mutual funds, has become po...

This paper examines NASS/CDS 1995 to 2001 in order to evaluate rollover crash severity metrics and to recommend additional data elements to assist in determining rollover severity. For belted occupants and unbelted ejected occupants in single vehicle crashes, the number of roof impacts is an appropriate severity indicator. For ejected occupants, the ejection risk generally increases with the nu...

to determine whether teenagers and young adults with attention deficit hyperactivity disorder (adhd) have more motor vehicle citations and crashes and are more careless drivers than their normal peers. in fact, studies have found that teenagers and adults with attention deficit disorder are nearly twice as likely as the general population to have had their licenses suspended. people with adhd h...

When a software system crashes, crash information from user's machine is sent to the developers of the system for repair. For software systems with a large client base (such as Eclipse, Web browsers, etc.), the number of reports that are submitted every day can be quite high. Managing these reports is known to be a tedious and a time consuming task. Fortunately, not all crashes are caused by ne...

Over recent years, researchers have used full-scale motorcycle crash tests in the field of road safety research to simulate different types of crash technique and scenario. This study focuses on the development of laboratory-based motorcycle crash tests. A moveable barrier, designated as a ‘trolley’ in this study, is designed, developed and implemented in a laboratory-based motorcycle crash tes...
