Relatively recent research has illustrated the potential that tobit regression has in studying factors that affect vehicle accident rates (accidents per distance traveled) on specific roadway segments. Tobit regression has been used because accident rates on specific roadway segments are continuous data that are left-censored at zero (they are censored because accidents may not be observed on a...

in this work, the time series modeling was used to predict the tazareh coal mine risks. for this purpose, initially, a monthly analysis of the risk constituents including frequency index and incidence severity index was performed. next, a monthly time series diagram related to each one of these indices was for a nine year period of time from 2005 to 2013. after extrusion of the trend, seasonali...

This project proposes an accident cost estimation model in the aviation industry in Nigeria. The model takes into consideration the probability of accidents and the cost of the potential consequences. Potential consequences of accidents are classified as human severity, property damage, and economic implications. The three classes of accidents identified in this study were fatal, serious, and m...

PURPOSE To review major radiation accidents that have occurred over a 50 year period. To identify common factors, since feedback may prevent recurrence. METHODS Accidents are classified according to the difficulties involved in their management and to the delay between their occurrence and their recognition. RESULTS The rate of severe accidents increases with time, especially those involvin...

Road traffic accidents (RTAs) are a major public health concern, resulting in an estimated 1.2 million deaths and 50 million injuries worldwide each year. In the developing world, RTAs are among the leading cause of death and injury; Ethiopia in particular experiences the highest rate of such accidents. Thus, methods to reduce accident severity are of great interest to traffic agencies and the ...
