• WreckWatch: Automatic Traffic Accident Detection and Notification with Smartphones
  • Abstract
    • Introduction
    • Challenges associated with automatically detecting car accidents
      • Challenge 1: detecting accident forces without electronic control unit interaction
      • Challenge 2: providing situational awareness and communication with victims to first responders
      • Challenge 3: preventing false positives
    • Solution approach
      • The WreckWatch client/server architecture
      • The WreckWatch formal accident detection model
      • Using acceleration events to detect collisions
      • Using acoustic events to detect accidents
      • Providing situational awareness to first responders
      • Potential advantages of smartphone-based accident detection systems
      • Potential disadvantages of smartphone-based accident detection systems
    • Empirical results
      • Experiment 1: evaluating the possibility of false positive acceleration values
      • Experiment 2: evaluating the possibility of acoustic false positives
      • Experiment 3: evaluating accident reconstruction capabilities
      • Experiment 4: evaluating false positives & negatives with crash data
