Abstract
A navigation system provides a position of the vehicle on a segment of a roadway and identifies a change in speed limit relative to the current segment of the roadway. A traffic sign recognition system determines a speed limit information presentation zone of the current segment of the roadway after determining that a speed limit of the approaching segment of the roadway is lower than a speed limit of the current segment of the roadway and/or a current speed of the vehicle. Thereafter, the traffic sign recognition system assesses the position of the vehicle relative to the speed limit information presentation zone. In response to determining that the vehicle is within the speed limit information presentation location, the traffic sign recognition system displays a visual representation of a speed limit sign designating the speed limit of the approaching segment of the roadway.
