Abstract
Systems and methods are disclosed and include receiving, using an electronic control module of a vehicle, image data from a camera system. The method includes identifying, using the electronic control module, a traffic sign based on the image data and information from a training database. The method includes determining, using the electronic control module, whether the traffic sign is correct based on a matching of the traffic sign and an entry of at least one of (i) a traffic rules database, (ii) a traffic customs database, (iii) a map information database, and (iv) a global positioning system (GPS) information database. The method includes identifying, in response to determining that the traffic sign is correct, a vehicle action from a vehicle action database corresponding to the traffic sign. The method includes outputting, in response to validating the vehicle action, a signal to a vehicle control module corresponding to the vehicle action.
