The method may include obtaining first sensor data associated with a road sign. The first sensor data may comprise at least one of one or more first positive observations of a road sign or one or more first negative observations of the road sign. The method may further include obtaining second sensor data for the road sign, for example, based on the first sensor data. The second sensor data may comprise cumulative historic road sign observation data for time duration. The method may include determining a sign confidence ratio based on the first sensor data and the second sensor data. The method may include updating the map data based on the sign confidence ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for updating map data in a map database","description":"A method, a system, and a computer program product may be provided for updating map data in a map database to indicate presence of a road sign.
