Abstract
A transport service system automatically associates road sign information with road segments based on image data including a representation of the road sign. The transport service system receives image data from one or more camera systems. Based on the image data, the transport service system determines a distance score and an orientation score for one or more candidate road segments. The transport service system additionally determines whether the image data is anomalous. Based on the determined distance and orientation scores, the transport service system generates a composite score and a confidence score for each candidate road segment. The confidence score is adjusted based on whether the image data is anomalous. Based on the generated scores, the transport service system identifies a most likely candidate road segment for association with the road sign.
