1. A method comprising:

  • receiving trajectory data representing a trajectory of a driverless, autonomous vehicle in an environment external to the autonomous vehicle;

    sensing an object in the environment;

    determining object data comprising a position of the object, an object type of the object, and an object classification of the object;

    determining one or more predicted locations of the object in the environment based on the object data;

    determining a predicted collision location based on the trajectory data and the one or more predicted locations of the object in the environment;

    determining a first threshold location in the environment between the object and the predicted collision location;

    determining a second threshold location in the environment between the object and the predicted collision location, the second threshold location being closer to the collision location than the first threshold location;

    sensing an updated position of the object in the environment;

    implementing a first safety action using a safety system in response to the updated position corresponding to the first threshold location; and

    implementing a second safety action using the safety system in response to the updated position corresponding to the second threshold location.
