| Abstract |
In this paper, we propose a prediction model for traffic accident injury grade using machine learning algorithm. We used machine learning models such as Decision Tree, Support Vector Machine, and Logistic Regression to predict injury grade. And to improve performance, Principal Component Analysis(PCA) or Linear Discriminant Analysis(LDA) was applied to each machine learning model. The data used in this study are based on NASS-CDS data that collects traffic accident investigation data and medical records of accident victims. According to the results, the proposed method is expected to be used in the automatic traffic accident notification system because of its reliable accuracy. |
