Evaluation Work Zone Accident MRT Risk Factors by Index Condition Model

Abstract

The risk assessment of the construction of the Mass Rapid Transit Authority of Thailand (MRT) is seen as essential, accompanies by working in the construction of the Mass Rapid Transit may cause a high number of accidents. However, there are many parties involved, so it is difficult to prevent construction accidents, leading to the social and environmental impacts in the work zone areas. This research was thus conducted to study accident risk factors related to the construction of the Mass Rapid Transit of Thailand. The identification of accident risk factors was carried out using four sample groups – project engineers, site engineers, safety officers and foremen. To create a decision-making model of the risk assessment, work zone accidents reports provide decision of risk assessment related MRT work zone constructions in the future. The result of the risk assessment in work zone areas of the Mass Rapid Transit Authority of Thailand using the Index Condition Model (MIC), the MIC shows that four risk factors involved work zones accidents are the most important - human factors, task factors, working environment factors and operation factors. Implementation of this overall risk assessment by the index condition model can be updated the present data.
