Work Zones

With CityStream Road Work Zones you can detect, monitor, and map all road work zones in your area of interest. Nexar automatically detects barricade elements in work zones using Artificial Intelligence. Recent images of these barricade elements are then aggregated, localized and mapped into CityStream Road Work Zones so you can remotely manage them and be WZDx ready.

Road Asset Inventory

Nexar detects road inventory - traffic signs and other furniture - localizes and places it on a map, giving you a fresh understanding of inventory instead of a once-a-year drive through. You can access the underlying images to see for yourself. Nexar also “sees” change, notifying you when road inventory changed, so you can see whether there is a safety or maintenance issue you need to tend to and act upon, Identify damaged, missing, or other changes in road signs, remotely.

Nexar’s CityStream provides road inventory service for monitoring traffic signs & signals

Virtual Camera
