The human loss in traffic crashes is tragic. More than six million motor vehicle collisions occur on the Nation’s highways every year, causing approximately 5.2 million injuries and more than 41,000 fatalities, and costing more than $150 billion per year. Approximately three-quarters of these collisions could be prevented if the driver’s attention had not been diverted moments before collision....

To address the issue of safely accessing and securing wheeled mobility devices in motor vehicles, more information characterizing current-production devices was needed. In a recent effort, frame characteristics of wheeled mobility devices were defined and a database developed for recording characteristics relevant to access and securement. A representative number of devices have been surveyed t...

Crash prediction models have been very popular in highway safety analyses. However, in highway safety research, the prediction of outcomes is seldom, if ever, the only research objective when estimating crash prediction models. Only very few existing methods can be used to efficiently predict motor vehicle crashes. Thus, there is a need to examine new methods for better predicting motor vehicle...

Millions of U.S. workers are at risk for a work-related motor vehicle crash. Fatality data show that across all industries, motor vehicle crashes are consistently the leading cause of work-related fatalities. Of 43,025 work-related fatalities reported by BLS between 2003 and 2010, 10,202 were the result of single- or multiple-vehicle crashes of workers driving or riding in a vehicle on a public...

Abstract To investigate the cavitation and hydrodynamic characteristics of supercavitating projectiles in shear flow, Mixture multiphase Schnerr-Sauer models are employed to simulate underwater projectiles. The inflow average velocity is 600 m/s, rates range from 0 7500 s −1 . In uniform supercavity enveloping vertically symmetrical. drag dominated by pressure drag, lift coefficient 0. However,...

in recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. the core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

Erratum After publication of the original article [1], the corresponding author (DF Murgatroyd) noticed that her name was inadvertently duplicated at the beginning and end of the author list. Similarly, the affiliation of this author (John Walsh Centre for Rehabilitation Research, The University of Sydney) had been duplicated as affiliations 1 and 5. The original article has been updated to cor...

It has been referred in document issued by the State Council recently that China will promote the block system gradually in the future, no more enclosed residential compounds will be built in principle, and existing residential and corporate will open up step by step as well. The proposal of open area quickly aroused a heated discussion in the whole society. In addition to the most basic securi...

OBJECTIVE We explored drivers' mobile device use and its associated risk of a safety-critical event (SCE) in specific driving contexts. Our premise was that the SCE risk associated with mobile device use increases when the driving task becomes demanding. METHODS Data from naturalistic driving studies involving commercial motor vehicle drivers and light vehicle drivers were partitioned into su...
