5. A traffic sign determination method comprising:
-
detecting a first traffic regulation sign by performing an image recognition process on an image of an area in front of a vehicle picked up by an imaging section provided on the vehicle; using a position of the vehicle to acquire a road link, including a second traffic regulation sign at the position of the vehicle, from a map data storage section storing map data that includes road link information related to roads constituting a map; when a current first traffic regulation sign is detected on a current road link, determining whether or not the current first traffic regulation sign detected on the current road link agrees with a current second traffic regulation sign acquired on the current road link; and when the current first traffic regulation sign does not agree with the current second traffic regulation sign, selecting the current first traffic regulation sign as the current traffic regulation sign to be notified to an occupant of the vehicle, until the position of the vehicle passes an end point of the current road link.
