flatland.envs.step_utils.action_preprocessing.preprocess_action_when_waiting(action, state)[source]#

Set action to DO_NOTHING if in waiting state

flatland.envs.step_utils.action_preprocessing.preprocess_moving_action(action, rail, position, direction)[source]#

LEFT/RIGHT is converted to FORWARD if left/right is not available and train is moving FORWARD is converted to STOP_MOVING if leading to dead end?

Preprocesses actions to handle different situations of usage of action based on context

  • DO_NOTHING is converted to FORWARD if train is moving
