Using Visualization Tool to Determine Roundabout Conflicts


Using Visualization Tool to Determine Roundabout Conflicts: Surrogate Safety Assessment Model (SSAM)
North Carolina DOT


In Summary

  • SSAM is a technique combining micro-simulation models and automated conflict analysis to assess the safety.
  • SSAM is a visual tool to support:
    • Identification conflict points, conflict types, conflict severity, and conflict zones
    • Analysis in terms of safety surrogate measures
    • Assessment alternatives
  • SSAM is an excellent tool to improve public involvement in terms of access management for driveways, alternatives, etc.
