Validation Approaches

Validation is essential to ensure the model 's predictive power. Common validation techniques include:

  • Comparing simulated lane distribution curves with field data from corridors that already have some AV presence (np., Waymo in Fenix, Cruise in San Francisco).
  • Using controlled experiments where a small AV fleet executes pre- defined lane- change Patterns while arounding human drivers are monitored.
  • Cross- validating against tell simulation platforms to ensure that observed lane utilization trends are nott artifacts of a single modeling paradigm.
