Title:

GIS STREETS Traffic Preventative Maintenance Districts

Description:

Abstract:

This layer identifies the preventative maintenance district boundaries for the Traffic Division of the City of Philadelphia Streets Department. Preventative maintenance is necessary for traffic signals and is performed while the equipment is still working, so that it does not break down unexpectedly.DATA DEVELOPMENT:Boundary Polygon Data was constructed by Streets GIS staff under the direction of the Traffic Engineering Divison and created using the most current composite layer in ArcGIS Desktop. (See update dates in summary)KEY ATTRIBUTE FIELDS:PM_DIST: Unique identifierSUB_DIST: Referenced subdistrict numberCOORDINATE SYSTEM:Lambert Conformal Conic, NAD83, PA South Stateplane coordinates, US Foot.THEMATIC MAPPING:Use the PM_DIST field for thematic mapping and labeling.

Purpose:

This layer was developed to aid the Traffic Division in planning, organizing, and maintaining traffic flow within the City of Philadelphia. Examples include: the maintenance and placing of stop signs and signals and monitoring street travel direction. This polygon layer has an accompanying arc layer. Certain arcs in the arc layer contain data signifying information relating it to the polygon layer. It can tell you if both sides of the arc belong to one of the bounding polygons. All the arcs, including those with no boundary info, have naming attributes for labeling the polygon borders. Contact the Streets GIS unit for public consumption of the corresponding arc layer.
