Abstract

Systems and methods to determine posted speed limits for vehicles and modify a centralized database of posted speed limits may manage the centralized database, receive, from a fleet of vehicles, requests to modify speed limits associated with roads, and modify the centralized database in accordance with the received requests for modification. Individual vehicles may compare a posted speed limit for a particular road as identified based on road-side image information with a previously stored speed limit from the centralized database for the same road in order to detect a discrepancy and transmit a request for a modification.
