Claim 0:
1. A method for use in traversing a vehicle transportation network, the method comprising:
traversing, by an autonomous vehicle, a vehicle transportation network, wherein traversing the vehicle transportation network includes:
identifying 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;
communicating, via wireless communications, shared scenario-specific operational control management data associated with the distinct vehicle operational scenario with an external shared scenario-specific operational control management system, wherein the external shared scenario-specific operational control management system is configured to communicate, via the wireless communications, the shared scenario-specific operational control management data to a second autonomous vehicle responsive to the second autonomous vehicle detecting a vehicle operational scenario that corresponds with the distinct vehicle operational scenario;
operating 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;

receiving, as a candidate vehicle control action, an action from the policy for the scenario-specific operational control evaluation model; and
traversing a portion of the vehicle transportation network based on the candidate vehicle control action, wherein the shared scenario-specific operational control management data includes the policy.
