Area of Science:

  • Road safety
  • Transportation engineering
  • Data science

Background:

  • Rising road traffic accidents (RTAs) in Korea pose significant economic and safety risks.
  • Accurate classification of RTA severity is vital for developing effective prevention strategies.

Purpose of the Study:

  • To identify key factors influencing road traffic accident severity.
  • To build and compare classification models for RTA severity using data-mining techniques.

Main Methods:

  • Utilized three data-mining techniques: neural network, logistic regression, and decision tree.
  • Applied these methods to select influential factors and develop accident severity classification models.
  • Compared the classification accuracy of the different models.

Main Results:

  • No significant difference in classification accuracy was observed among the neural network, logistic regression, and decision tree models.
  • The study identified the protective device as the most significant factor influencing accident severity.

Conclusions:

  • Data-mining techniques provide effective tools for analyzing RTA severity factors.
  • Focusing on the use of protective devices is critical for mitigating the severity of road traffic accidents in Korea.
