- Abstract
In view of urban public traffic safety, the accident tree analysis(ATA) theory was applied to construct an accident tree model which taken the children fall accident in the escalator area as the top event. According to the accident tree model, the Boolean algebraic function expressions of the accident tree and the success tree were obtained, the minimum cut set and the minimum path set were also determined, and the ranking of structural importance of the basic events was obtained. According to the similar events’ probability of relevant literatures, the basic events’ probability were initially assigned, the ranking of probability importance and critical importance of each basic event structure were also obtained. Through the risk assessment and analysis of the results of the three important rankings, it was shown that children climbing the handrails, no supervision, inadequate adult supervision, no pre-fall prevention devices, post-fall prevention devices were the important factors affecting the children fall accident.
