Systems and methods for traffic sign detection

A system for enhancing map data of a road network, the system comprising:

• at least one data storage operable to store telematics data originating from a plurality of telematics devices installed in a plurality of vehicles;
• and
• at least one processor in communication with the at least one data storage, the at least one processor operable to:
• receive telematics data originating from a plurality of telematics devices installed in a plurality of vehicles;
• receive the map data wherein the map data comprising a plurality of road edges,
• determine a point of interest associated with at least one road edge of the plurality of road edges, wherein the determination of the point of interest is based on a vehicle movement metric derived from the telematics data of the plurality of vehicles traversing the at least one road edge;
• determine a sequence of one or more images associated with the determined point of interest wherein the sequence of one or more images is captured by an image capture device positioned at a vehicle traversing the determined point of interest;
• and
• analyze at least one image from the sequence of one or more images using a machine learning model to detect a traffic sign therein for using the detected traffic sign to enhance the map data.
