DCSign: GIS Inventory and Analysis of Traffic Signs
Track: Public Works
Authors: James Graham, John Hudler

With an over 1 million traffic signs to manage and no GIS inventory, Washington DC had a huge problem on its hands. We had no idea where the signs were, what was old and in need of replacement, or if existing signs conflicted with each other or with existing regulations. DDOT was even the subject of several local news articles which highlighted our 'conflicting signage'. This presentation shows how we built our inventory with an LRS approach, using MAVRIC and ESRI's Roads and Highways.
