Driver Interaction at Intersections: A Hybrid Dynamic Game Based Model

A new concept for modeling the behavior and the interaction between drivers at intersections is presented. For this purpose a hybrid dynamic game is introduced using the concepts of game theory. The proposed hybrid game is used to model the interactive behavior in a junction scenario. The presented hybrid approach divides the modeling of motion into individual maneuvers. With this partition of motion, the decision process can be reduced to a simple maneuver selection that takes into account the motion of the vehicle without the need for solving complex coupled differential equations. In order to make computation of a solution feasible we propose a rule based adaption mechanism. Simulation is used to show the applicability of the developed hybrid dynamic game approach.
