One example includes an autonomous vehicle control system. The system includes an operational plan controller to maintain operational plans that each correspond to a predetermined set of behavioral characteristics of an associated autonomous vehicle based on situational awareness data provided from on-board sensors of the autonomous vehicle and mission control data provided from a user interface. The system also includes a decision-making algorithm to select one of the operational plans for operational behavior of the autonomous vehicle based on the situational awareness data and the mission control data at a given time and to provide an intent decision based on the situational awareness data and the selected one of the operational plans. The system further includes an execution engine to provide control outputs to operational components of the autonomous vehicle for navigation and control based on the selected one of the operational plans and in response to the intent decision.
