Abstract
System, methods, and other embodiments described herein relate to avoiding deadlocks between vehicles through adjusted maneuvering. In one embodiment, a method includes predicting vehicle trajectories using a model generated from sensor data and information communicated to a subject vehicle. The method also includes estimating, by the subject vehicle, deadlock parameters using the vehicle trajectories. The method also includes, in response to the deadlock parameters satisfying a threshold, avoiding a deadlock by communicating a maneuver message (MM) that suggests a maneuver for nearby vehicles according to vehicle parameters or by executing a motion adjustment initiated by the subject vehicle that reduce conditions for traffic conflicts according to the deadlock parameters.
