　　Since we have to maintain the traffic accident scene while Traffic Accident occurs or the police officer takes a lot of time dealing with the traffic accident, the traffic flow is certainly being influenced by accidents.

　　The Traffic Accident Appraisal Committee ( TAAC ) is composed of experts of three fields: experts on law, vehicle engineering and traffic engineering. Members of TAAC will have quarrels on the conclusions of accident authentication due to different comprehension to the laws quoted and the insufficient evidences. To the perspective on the commissioners of TAAC, the identical criterions on priorities of the factors on accident authentication is necessary. It can not only reduce the quarrels of the commissioners but also speed up the investigates. And more over, it can assist commissioners to conclude the cause of the accident. Since the predict model can determine the cause of accidents fast and accurate , saving litigants’ valuable time, it is obviously a classic issue for us to dig into.

　　To the perspectives above, the study on building the predict model and determining the weight of vehicle accident authentication effective factors is necessary. Taking analysis the priorities of vehicle accident authentication effective factors as this study’s main idea, through the 273 sample data collected from TAAC of Taipei country which conform with the definition of two vehicles accident at intersection, listing the 18 variables that may effect the judgments on the cause of accident authentication by literature review. Using discriminant analysis to conduct 12 variables that effect the accident authentication. Using the information above, designing an AHP questionnaire that contains three aspects and eleven criteria. By the subjective opinions of commissions from different TAAC of Taiwan filled in the questionnaire, we can analysis the weights and the priority of each criteria and get to know the importance of effective variables of two vehicle accident authentication at intersection.
