Intersections and busy roadways have numerous signs in various directions making inventorying them complicated.
All signs decay eventually, it is only through vigilant monitoring that road managers can effectively identify and phase out those signs.
Especially in urban areas, signage can be extremely dense. This makes it challenging to identify obstructions and to correctly label all images.
Overgrowth can significantly affect driver visibility. Without continuous monitoring, road managers have the difficult task of continuously monitoring all signs without a systematic process to ensure quality.
Many of the signs on the road are in excellent condition. Wasting time manually categorizing only reduces available resources for repairing more damaged signs.
Some signs have moved beyond their useful life and pose significant safety hazards. It is imperative that a full inventory uncover these problems and give road managers the tools needed to remedy the situation.
