Claim 14:
15. 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;
receiving, using wireless communications, shared scenario-specific operational control management data associated with the distinct vehicle operational scenario from an external shared scenario-specific operational control management system;
operating a scenario-specific operational control evaluation module instance using a previously generated policy of a machine learning algorithm and operational experience data, 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,
operating the scenario-specific operational control evaluation module instance using the previously generated policy and the operational experience data 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, wherein:
the shared scenario-specific operational control management data includes the operational experience data,
the operational experience data is generated by a second autonomous vehicle in response to traversing a correlated vehicle operational scenario,
the operational experience data is transmitted, via the wireless communications, from the second autonomous vehicle to the external shared scenario-specific operational control management system, and
identifying the policy for the scenario-specific operational control evaluation model includes solving the scenario-specific operational control evaluation model using the operational experience data;

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.
