| Description | |||
| Abstract: Represents "Roads," which are linear features positioned along the center of the Traveled Way between two at-grade intersections. (It is always a single line representation, even when a divided street is present, such as with a median) | |||
| Purpose: Used for alternate street naming methodologies, and for alternate cartographic display of street centerlines as a single line, which is helpful for mapping at smaller scales, i.e. 1:30,000+. According to the City's GIS Data Quality Standards, Roads are of the highest priority feature type upon which thematic/administrative area boundaries are to be defined; they are used in topological constructs of features. | |||
| Supplemental Information: Roads are not used for linear referencing or for street routing analysis; the City uses Carriageways for those purposes. Notes: Must only touch other Roads at their endpoints (nodes) unless the intersection is a bridge or tunnel. May be split to accommodate attribute changes (such as street name or address range). Generally follow the center of the median along divided roads. This may not always be the exact center of the traveled way, but it presents a neat appearance. Do not model traversability. Intersections of Road features will sometimes lie inside a median. Provide edges for many polygon feature classes. Relate to one or more Carriageways. Feature level metadata is provided in the EditBy and EditDate fields. Every feature in the GIS layer tracks who edited it, and when it was last edited.
