A Traffic Sign Recognition (TSR) device which acquires traffic sign information on a traffic sign positioned on a road through a camera, receives road information from a navigation terminal configured to create and display a driving path of a vehicle and outputs a speed limit of the driving path of the vehicle, comprising:

  • an electronic control unit configured to provide a speed limit updated from the navigation terminal, if the acquired traffic sign information does not provide speed limit information but a road attribute contained in the road information is changed or the acquired traffic sign information is indication information indicating a changing of a speed limit, based on the acquired traffic sign information acquired through the camera and the road information being received from the navigation terminal while the vehicle travels along the driving path,wherein the electronic control unitrecognizes the speed limit of the acquired traffic sign information when the vehicle travels on an expressway, anddecides the speed limit updated from the navigation terminal as the speed limit of a driving road, when the vehicle is traveling at a higher speed by a predetermined speed or more than the speed limit within a preset reference distance or traveling at a higher speed by a preset reference speed or more than the speed limit of the acquired traffic sign information.
