many studies have been conducted focusing on the effects of friction coefficient or texture depth on the highway accident risk. however, combined effects of these parameters have not been still addressed. in this research the interaction between friction coefficient, texture depth and accident rate in 30 freeway sections were examined. the accident data were gathered and an apparatus was design...

To begin a zero accident campaign for industry, the first thing is to estimate the industrial accident rate and the zero accident time systematically. This paper considers the social and technical change of the business environment after beginning the zero accident campaign through quantitative time series analysis methods. These methods include sum of squared errors (SSE), regression analysis ...

background: there is a high prevalence of  occupational injuries due to accidents in construction industries which affect human health. therefore, the exploration and analysis of contributing factors of such accidents can lead to their prevention and the reduction of their consequences. this study was conducted with the aim to identify factors related to occupational injuries and the severity o...

Traffic accident data are often heterogeneous, which can cause certain relationships to remain hidden. Therefore, traffic accident analysis is often performed on a small subset of traffic accidents or several models are built for various traffic accident types. In this paper, we examine the effectiveness of a clustering technique, i.e. latent class clustering, for identifying homogenous traffic...

Accident models play a critical role in accident investigation and analysis. Most traditional models are based on an underlying chain of events. These models, however, have serious limitations when used for complex, socio-technical systems. Previously, Leveson proposed a new accident model (STAMP) based on system theory where the basic concept is not an event but a constraint. This paper shows ...

FOREWORD Safety analysis reports (SARs) represent the most comprehensive compilation of specific information relevant to the safety of a nuclear power plant (NPP). They serve as the basis for assessment of the overall NPP safety status, as well as for modifications and improvements of plant hardware, procedures and operation. For the regulatory body the SAR is the essential document for the lic...
