1. A method for visual indication of direction of travel of a bidirectional autonomous vehicle, comprising:

  • receiving data representing a trajectory of the bidirectional autonomous vehicle in an environment;

    causing the bidirectional autonomous vehicle to navigate in a first direction of travel that corresponds to the trajectory, wherein a first end of the bidirectional autonomous vehicle is facing the first direction of travel;

    selecting data representing a first directional light pattern, wherein the first directional light pattern is configured to indicate the first direction of travel of the bidirectional autonomous vehicle;

    selecting a light emitter of the bidirectional autonomous vehicle to emit light into the environment;

    causing, using the data representing the first directional light pattern, the light emitter to emit the light to visually convey the first direction of travel of the bidirectional autonomous vehicle;

    detecting that the bidirectional autonomous vehicle is switching from navigating in the first direction of travel to a second direction of travel, wherein a second end of the bidirectional autonomous vehicle is facing the second direction of travel;

    selecting data representing a second directional light pattern, wherein the second directional light pattern is configured to indicate the second direction of travel of the bidirectional autonomous vehicle; and

    causing, using the data representing the second directional light pattern, the light emitter to emit the light to visually convey the second direction of travel of the bidirectional autonomous vehicle,wherein the second directional light pattern and the first directional light pattern are substantially symmetric about an axis of the bidirectional autonomous vehicle.
