Systems and methods are provided for classifying one or more images of video data captured by a camera in a vehicle. The classification involves a detection of a traffic control device, such as a U-Turn sign, in image data. The classification further involves querying a database with a location of the vehicle from which the traffic control device was observed. In some embodiments, the database contains entries for various types of traffic control devices from a family of traffic control devices, where each type of traffic control device in the family has a similar visual appearance. The database query may therefore help disambiguate the visually perceived traffic control device at a particular location. Embodiments may be incorporated into navigation or driver safety systems.
