Autonomous vehicle operational management may include traversing, by an autonomous vehicle, a vehicle transportation network. Traversing the vehicle transportation network may include generating an autonomous vehicle operational control environment for operating scenario-specific operational control evaluation module instances. A scenario-specific operational control evaluation module instance maybe an instance of a respective scenario-specific operational control evaluation module. A scenario-specific operational control evaluation module may model a respective distinct vehicle operational scenario. A scenario-specific operational control evaluation module instance may generate a respective candidate vehicle control action responsive to the respective corresponding distinct vehicle operational scenario. Traversing the vehicle transportation network may include operating a scenario-specific operational control evaluation module instance, receiving a first candidate vehicle control action from the first scenario-specific operational control evaluation module instance, and traversing a portion of the vehicle transportation network based on the first candidate vehicle control action.
