This study describes four statistical models—Poisson; Negative Binomial; Zero-Inflated Poisson; and Zero-Inflated Negative Binomial—which were devised in order to examine traffic accidents and estimate the best probability estimating model in terms of future risk assessment at interurban road sections. The study was conducted on four sets of fixed-length sections of the road network: 500, 750, ...

The research objective of this work was to describe typical accident scenarios for pedestrian accidents. The accident analysis forms a component of work by the AEB Test Group which aims to develop test procedures for assessing Autonomous Emergency Braking (AEB) systems. This technology is penetrating the vehicle market and is designed to offer protection against the occurrence and severity of c...

Determination of attentional status is important because working performance and an unexpected accident is highly related with the attention. The autonomic nervous and the central nervous systems can reflect the changes in person’s attentional status. Reduced number of suitable pysiological parameters among autonomic and central nervous systems related signal parameters will be critical in opti...

This work analyses blunt abdominal trauma produced by driver-handlebar collision, in low speed two-wheel accidents. A simplified dynamic model is introduced, whose parameters have been estimated on the basis of cadaver tests. This model allows calculating the peak impact force and the abdominal penetration depth; therefore the likelihood of occurrence of serious injuries can be estimated for di...

The ESA-funded SEVESEO project aims at developing a decision-making tool that integrates environmental parameters derived from satellite imagery with pollutant transport models in order to support the risk management at Seveso-II industries. The development of the SEVESEO Information System (SEVESEO IS) implies the integration of contaminant transport models that aim at determining the environm...

Sight distance obviously affects safety. Although this statement is universally accepted, the relationship between sight distance and safety has not yet been successfully quantified. One reason for this is the obvious strong correlation between sight distance and alignment. Where roads have no vertical or horizontal alignment change, the available stopping sight distance (SSD) is not limited by...

The Integrated Safety Assessment Model (ISAM) is being developed by the FAA to provide a baseline risk assessment for the National Airspace System. The model consists of a set of event trees, each describing a set of possible event sequences occurring following an initiating event, such as an engine failure. Probabilities associated with the initiating events and end events of the trees are typ...

Aviation is one of the critical modes of our national transportation system. As such it is essential that new technologies be continually developed to ensure that a safe mode of transportation becomes even safer in the future. Data analyses in aviation improve safety. Analyzed air crash details plays very important role to avoid further unforeseen accidents. Air crash details of data’s are clas...

Traumatic brain injuries (TBIs) are a major health and socioeconomic problem throughout the world, with an estimated 10 million deaths and instances of hospitalization annually. Numerical methods such as finite element (FE) methods can be used to study head injuries and optimize the protection, which can lead to a decrease in the number of injuries. The FE head models were initially evaluated f...
