교통사고 유형별 발생 유무별 영향요인 판별 및 분류모형 구축에 관한 연구

Abstract

Damages such as casualty and social cost are continuously increasing due to traffic accidents. Accurate analysis on traffic accident-concerned problems should be preceded to secure reduction of traffic accidents. Discriminant and Classification Model of Influence Factors based on Typology(death, serious injury, minor injury, injury) and whether or not traffic accidents happen is constructed using Quantification theory Ⅱ and Logistic Regression Analysis. Based on this, institutional improvements are deducted as follows. First, valid Discriminant and Classification Model of Influence Factors based on Typology and whether or not traffic accidents happen is constructed by Quantification theory Ⅱ and Logistic Regression Analysis. Second, as a result of Discriminant Model by Quantification theory Ⅱ, correlation ratio of death, serious injury, minor injury and injury is 0.99954. This Discriminant Model compatibly explains dividing factors of external variables. Third, as a result of construction of Classification Model by Logistic Regression Analysis, -2LL is 2.5~12.3% more valid after Model construction than before Model construction. The significance level of Model and Improvement is also significant. Forth, reduction measures which should be enforced in priority and in complement are suggested.
