1. A method for updating a remote geographic database at specified times, the method comprising:
- receiving sensor data indicative of a road furniture item;
determining a geographic position associated with the road furniture item;
delaying based on a first comparison of a current time to a predetermined time;
performing a second comparison of the geographic position and the data indicative of the road furniture item to a local database; and
sending an update to the remote geographic database in response to the first comparison and the second comparison.

Abstract
A road furniture item or another type of road object is detected by at least one sensor. An associated geographic position associated with the road furniture item or road object is determined. After a predetermined time is reached, the geographic position is compared to a local database. A remote database is updated after the predetermined time is reached and according to the comparison with the local database. In some examples, the data indicative of the road furniture item or the road object is deleted based on a confidence level in the local database.

11. An apparatus for sending updates to a remote database at predetermined times, the apparatus comprising:
-
a sensor configured to receive sensor data indicative of a road object; a position detector configured to determine a geographic position associated with the road object; and a controller configured to determine when a predetermined time has elapsed since the sensor data was received, compare the geographic position of the road object to a local database, and generate an update message for the remote database in response to the predetermined time elapsing. - View Dependent Claims (12, 13, 14)

15. A method for geographic database updates, the method comprising:
-
receiving sensor data indicative of a road furniture item; determining a geographic position associated with the road furniture item; identifying a confidence value in a local database; comparing the confidence value to a confidence threshold; and discarding the sensor data indicative of the road furniture item in response to the confidence value exceeding the confidence threshold. - View Dependent Claims (16, 17, 18, 19)
