Research On The Analyzing Method Of Traffic Accident Causation

In recent years, with the fast development of our transportation, the number of traffic accidents and the number of deaths keeps increasing, which brings huge economic loss to the country and the people. Research on traffic accident causation also rest on traditional statistical method phases, in despite for ages. Cognizance the accident efficient amse are used for accident treatment, but ignore the accident causation research, which causes the accident data using insufficient.The text first discusses academic research of the traffic accident causation. According to the analysis and research of the accident happening mechanism, to find out the theory and way of prevention of road accident and prevent the happening of road accident.Based on the theoretic research of reason of road accident, we use twostep clustering analysis technology to research the current road accidents, we raise out the data requirement of twostep clustering analysis technology. We filter out couple of causing reasons, and finally confirm the accident -prone locations, also give out the main reason of traffic accident.The text raises fault tree analysis to analyse road accident. According the the analysis of the traffic accident, we set up fault tree model of freeway accident, give out the way of qualitative analysis and quantitative analysis, also we give out solve of minimum cut sets and construction importance. By doing so, we can understand what infaust elements will cause the accident, and also the important degree of the infaust elements, thus ,according to the above information to lauch the prevention work of traffic accident.
