Claim 7:
8. An autonomous vehicle comprising:
a non-transitory computer readable medium including instructions for traversing a vehicle transportation network;
a trajectory controller configured to operate the autonomous vehicle;
a wireless communication link; and
a processor configured to execute the instructions stored on the non-transitory computer readable medium to:
identify a distinct vehicle operational scenario, wherein traversing the vehicle transportation network includes traversing a portion of the vehicle transportation network that includes the distinct vehicle operational scenario, and wherein to identify the distinct vehicle operational scenario comprises to identify the distinct vehicle operational scenario in accordance with operational environment data representing an operational environment for the autonomous vehicle;
communicate, using the wireless communication link, shared scenario-specific operational control management data associated with the distinct vehicle operational scenario with an external shared scenario-specific operational control management system;
operate a scenario-specific operational control evaluation module instance using a previously generated policy of a machine learning algorithm,
wherein the scenario-specific operational control evaluation module instance includes an instance of a scenario-specific operational control evaluation model of the distinct vehicle operational scenario, and
wherein operating the scenario-specific operational control evaluation module instance using the previously generated policy includes identifying a policy determined by solving the scenario-specific operational control evaluation model by evaluating possible combinations of elements that define the scenario-specific operational control evaluation model;

receive, as a candidate vehicle control action, an action from the policy for the scenario-specific operational control evaluation model; and
output the candidate vehicle control action to the trajectory controller as a vehicle control action such that the trajectory controller controls the autonomous vehicle to traverse a portion of the vehicle transportation network in accordance with the vehicle control action, wherein the shared scenario-specific operational control management data includes the policy.
