What is CityStream Road Inventory?


With CityStream Road Inventory you can detect, monitor, and map traffic signs & signals. Nexar automatically detects traffic signs using Artificial Intelligence in our dash cams and application. Recent images of these detections are then aggregated, localized and mapped so you can remotely monitor them.
