Safety risk study on road transportation of hazardous chemicals is a reliable basis for the government to formulate transportation planning and preparing emergent schemes, but also is an important reference for safety risk managers to carry out dangerous chemicals safety risk managers. Based on the analysis of the transport safety risk of dangerous chemicals at home and abroad, this paper studi...

road managers, such as the ministry of roads and municipals, are in charge of the construction and maintenance of roads. in cases where the defect of the road or failure to observe the safety rules is effective in a car accident, the road managers may be considered as the liable of the harm. their liability is based on civil liability rules and approved special acts. we analyze the civil liabil...

Road construction projects are very expensive, unpredictable and highly influenced by unpredictable factors, like weather, type of soil, environmental issues, and other factors. This has led to difficulties in developing accurate construction plans and modelling the construction operation using a traditional simulation system. In this context, the aim of this research is to create a knowledge d...

Given the current number of road accidents, the aim of many road safety analysts is to identify the main factors that contribute to crash severity. To pinpoint those factors, this paper shows an application that applies some of the methods most commonly used to build decision trees (DTs), which have not been applied to the road safety field before. An analysis of accidents on rural highways in ...

Well maintained road network is an essential requirement for the safety and consistency of vehicles moving on that road and the wellbeing of people in those vehicles. On the other hand, guaranteeing an adequate maintenance by road managers can be achieved via having sufficient and accurate information concerning road infrastructure quality that can be as well utilized concurrently by the widesp...

OBJECTIVES To assess professional status (PS) differences in the risk of road crash involvement (RCI) (irrespective of crash severity), and to examine the underlying mechanism by evaluating the role of exposure to road risk (ERR). METHOD A total of 15,271 subjects selected from the French GAZEL cohort were studied. A proportional hazard model for recurrent events was used to calculate the rel...

The World Bank USA Lead Highway Engineer Henry Godfrey Rupiny Kerali This paper describes the development of a stochastic model for the strategic assessment of road maintenance funding and policy decisions. The algorithms used for simulating pavement deterioration utilise Markov processes, resulting in a transition probability matrix that defines defect progression as opposed to the more famili...
