1. A method of determining a speed limit, the method comprising;

  • receiving a first probability distribution from a camera based speed limit assistant (SLA) system, wherein the first probability distribution includes probabilities that an image processed by the camera based SLA corresponds to a discrete set of speed limits;

    receiving a second probability distribution from a global positioning system (GPS), wherein the second probability distribution includes probabilities that a coordinate processed by the GPS corresponds to the discrete set of speed limits; and

    determining a final speed limit from the discrete list of speed limits based on the first and second probability distributions.
