This article describes how a geographic information system (GIS) which uses routing software and turn-restriction information was created for use by the Public Works Solid Waste Management Administration (DPW- SWMA) in Washington, D.C., as well as the D.C. Department of Transportation (DDOT). The system contains data on more than 20,000 intersections and close to 1100 miles of street and alleys in the area. The data is used for applications such as snowplow mapping, street sweeping, and garbage truck routing. The article describes how the application was created and the turn restrictions recorded for each intersection. The system is also used in combination with a program that finds the quickest or shortest route to provide support for emergency routing.
