Create and monitor Road Inventory remotely and frequently
Use the power of Nexar’s dash cam network& AI for better management of road assets


What is 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.
Improve asset planning & design
With fresh visual data from your roads, you can better monitor & plan changes to your roadway inventory.
