This study developed a new algorithm for automatic collision notification systems using Japanese police accident data. The TOYOTA-Nihon University algorithm accurately predicts injury severity to improve emergency response for traffic accident victims.

Area of Science:

  • Traffic Safety
  • Emergency Medicine
  • Algorithm Development

Background:

  • Existing serious-injury prediction algorithms often rely on limited datasets like the US National Automotive Sampling System/Crashworthiness Data System.
  • There is a need for advanced automatic collision notification systems that can accurately assess injury severity in real-time.
  • Improving the rescue of injured vehicle occupants is a critical aspect of traffic accident management.

Purpose of the Study:

  • To construct and validate a novel algorithm for an advanced automatic collision notification system.
  • To utilize comprehensive Japanese national traffic accident data for algorithm development.
  • To enhance the prediction of injury severity for traffic accident victims.

Main Methods:

  • Development of an algorithm using a sample of Japanese police accident data, incorporating factors like pseudo delta-V, impact location, seatbelt use, and occupant age.

  • Validation of the algorithm using receiver operating characteristic analysis on the remaining police data.
  • In-depth investigation of accident injuries in collaboration with emergency care institutes for further validation.
  • Main Results:

    • A simple and practical algorithm, the TOYOTA-Nihon University algorithm, was successfully constructed for onboard vehicle installation.
    • The algorithm demonstrated comparable utility to existing systems like the US URGENCY algorithm.
    • Under-triage analysis showed the algorithm could achieve an under-triage rate below 10% with a threshold of 8.3%.

    Conclusions:

    • The TOYOTA-Nihon University algorithm is a validated tool for advanced automatic collision notification systems.
    • The algorithm effectively utilizes comprehensive police data to predict injury severity, aiding in timely rescue operations.
    • This system has the potential to significantly reduce under-triage rates and improve patient outcomes in traffic accidents.
