INTERACTIVE AUTONOMY

Socially compatible driving

Game-theoretic and interaction-aware autonomous-vehicle decisions for mixed traffic, including cooperative, competitive, and uncertain human behavior.

  • Interactive lane changing and gap negotiation
  • Bounded-rational and cognitive-hierarchy driver models
  • Social value orientation and cumulative prospect theory

BEHAVIOR PREDICTION

Human behavior and motion prediction

Methods for estimating driver intent, preferences, and future motion so autonomous vehicles can anticipate the effects of their actions on surrounding road users.

  • Driver heterogeneity and behavior modeling
  • Context-aware trajectory and maneuver prediction
  • Prediction-informed motion planning
