Motorist complaints via an experimental website can help identify road hazards proactively. This internet-based method, when combined with crash data, aids in detecting new safety issues before accidents occur.

Area of Science:

  • Transportation Engineering
  • Public Safety

Background:

  • Highway agencies traditionally rely on crash statistics to identify hazardous road locations.
  • The crash-based method is reactive, identifying problems only after sufficient incidents occur.
  • A proactive approach is needed to detect road hazards before crashes happen.

Purpose of the Study:

  • To investigate the quality of safety information from motorist reports.
  • To evaluate the effectiveness of using motorist reports for hazard identification.
  • To explore the potential of an internet-based system for proactive road safety.

Main Methods:

  • Collected motorist reports on road hazards using an experimental internet website.
  • Analyzed the correlation between reported hazards and actual crash data.

  • Compared the data yield of the internet-based method to traditional crash data.

    • Main Results:

    • Intersections identified by motorists showed a higher incidence of crashes.
    • Safety information from the website was comparable to 2-3 months of crash data.
    • Motorist reports provided valuable, timely safety insights.

    Conclusions:

    • Internet-based motorist reports offer a proactive complement to traditional crash-based methods.
    • Combining internet reports with crash statistics can improve the detection of emerging road hazards.
    • This approach is particularly useful in areas with limited historical crash data.
