Case Study: Los Angeles County Department of Public Works achieves faster, automated inventory of 30,000 traffic signs with Mapillary

Los Angeles County Department of Public Works - Customer Case Study

The Los Angeles County Department of Public Works used Mapillary to rapidly inventory 30,000 traffic signs across unincorporated county roads. Inspectors faced the challenge of routinely capturing and refreshing sign data over a large network and relied on simple equipment—iPhones and action cameras mounted on vehicle windscreens—for data collection.

Mapillary’s solution lets inspectors upload captured imagery, view it in ArcGIS, and automatically extract traffic sign locations and attributes which are provisioned as GIS-ready shapefiles. By automating extraction and integration, Mapillary enabled fast refreshes and a complete inventory of ~30,000 signs, significantly reducing manual effort and accelerating asset management.
