Background: Every year many people are killed or injured in road accidents. The first step in planning to reduce accidents is to identify the causes of accidents. This study aimed to investigate and identify the causes and factors affecting the incidence and the severity of road accidents as a major issue in Ilam Province, Iran. Materials and Methods: This research is a descriptive study with an analytical approach. Descriptive and inferential statistics indices were used for statistical analysis. A researcher-made questionnaire as fieldwork was used to investigate the factors affecting accidents. Friedman test was used in the analytical study of the data obtained from the questionnaires. The study population included all drivers of the public suburban fleet, including taxis, minibusses, and buses on the Ilam Province. Out of 190 drivers, a sample size of 127 was selected using a Cochran formula. Results: From the drivers’ point of view, the main causes of public fleet accidents on the roads of Ilam Province are the quality and technical issues of the roads. Interviewees believed that dangerous turns, low width, poor road quality, and inadequate traffic signs are the main causes of accidents. After that, human factors are in the second place, including high speed and overturning, left-sway, and unmanageable rush, emphasizing the two factors of high speed and overtaking. The technical and qualitative factors of the vessels are in third place. Finally, the environmental and natural factors are in fourth place. Conclusion: Because the drivers consider the quality and technical issues of the roads as the main causes of traffic accidents in the transportation axes of Ilam Province, it is necessary to review and repair these transportation axes.

“…These techniques have traditionally focused more on single hazards while ignoring the dynamic interactions between hazards originating from escalator equipment, passengers, the surrounding environment, and maintenance in the escalator accidents. However, according to Heinrich’s Law [ 20 ], casualty accidents are not the result of an isolated hazard, but the result of a series of hazards [ 21 , 22 ]. In MRT escalator system, accidents are much more likely to be caused by multiple hazards, rather than a single hazard [ 2 ].…”

Escalator accidents not only happen frequently but also have cascading effects. The purpose of this study is to block the formation of cascading accident networks by identifying and preventing critical hazards. A modified five-step task-driven method (FTDM) is proposed to break down passenger-related cascading escalator accidents. Three complex network parameters in complex network theory are utilized to identify critical and non-critical Risk Passenger Behavior (RPB) hazards and Other Hazards related with Risk Passenger Behavior (OH-RPB) in accident chains. A total of 327 accidents that occurred in the Beijing metro rail transit (MRT) stations were used for case studies. The results are consistent in critical and non-critical RPB and OH-RPB and prove that through combination of FTDM accident investigation model and complex network analysis method, critical and non-critical RPB and OH-RPB in a complicated cascading hazards network can be identified. Prevention of critical RPB can block the formation of cascading accident networks. The method not only can be used by safety manager to make the corresponding preventive measures according to the results in daily management but also the findings can guide the allocation of limited preventive resources to critical hazards rather than non-critical hazards. Moreover, the defects of management plan and product design can be re-examined according to the research results.
