The New York City Department of Transportation (NYCDOT) has implemented a $1.7 million combined system of computer-aided drafting and design (CADD) and geographic information systems (GIS) to meet departmental needs. NYCDOT builds and manages 10,459 km (6,500 mi) of roads that weave through the city's five boroughs, along with signs, signals, and other appurtenances. Drafting and design has been re-engineered with CADD, creating "intelligent" drawings that carry dimension and location information and can be manipulated to produce accurately scaled graphic representations. CADD is also useful in document management, where previously prepared drawings can be scanned and stored electronically. GIS mapping is allowing other city agencies to share base maps with NYCDOT. New GIS applications in development include bridge mapping and inspection, pothole tracking, incident analysis, and parking-meter analysis. NYCDOT is uncovering new uses for the CADD/GIS package every day.
