  • generating a light signal having light structures;

    emitting the light signal onto the roadway;

    receiving reflected radiation of the light signal off at least the roadway;

    generating a light pattern as a function of the received reflected radiation;

    evaluating the light pattern;

    during the evaluating, detecting pattern characteristics of the light pattern that correspond to at least some of the light structures of the light signal;

    analyzing a geometry of the detected pattern characteristics; and

    inferring a surface of the roadway based at least on the analyzing.
