Claim 18:
19. A method for use in traversing a vehicle transportation network, the method comprising:
traversing the vehicle transportation network, by an autonomous vehicle, wherein traversing the vehicle transportation network includes:
operating a scenario-specific operational control evaluation module instance, wherein the scenario-specific operational control evaluation module instance includes an instance of a scenario-specific operational control evaluation model of a distinct vehicle operational scenario, and wherein operating the scenario-specific operational control evaluation module instance includes identifying a multi-objective policy for the scenario-specific operational control evaluation model, wherein the multi-objective policy includes a topological graph that shows a relationship between at least two objectives;
receiving, from the multi-objective policy for the scenario-specific operational control evaluation module instance, candidate vehicle control actions associated with each of the at least two objectives;
determining a probability of success of each of the at least two objectives based on a competence measure that is incorporated into a partially observable Markov decision process (POMDP) state transition to obtain a restricted number of available actions;
selecting a vehicle control action from the restricted number of available actions based on a buffer value, wherein the selected vehicle control action is one of the candidate vehicle control actions; and
traversing a portion of the vehicle transportation network by performing the selected vehicle control action.
