| Description | |||
| Abstract: Represents unit of pavement, as assigned to carriageway features. Pavement Carriageways were interpreted from VDOT's pavement sections inventory of the City of Richmond. Typically, VDOT's pavement section definitions can span multiple blocks, while carriageways are hightly segmented; the pavement section will frequently be repeating for each unique carriageway feature, so the PavementID is not a unique record. | |||
| Purpose: Created to support Public Works' Pavement Management and GIS mapping. Pavement Carriageways are subsequently dissolved to create Pavement Sections. | |||
| Supplemental Information: The table named, "tran_pavement_event" is the GIS event table that is the source were the City maintains the translation of VDOT's pavement sections to our carriageways. Pavement sections are stored in an event table because VDOT pavement sections will sometimes terminate "along" an existing carriageway feature, such as 100 feet from an intersection in a mid-block location. The transportation model (carriageways) is not to be highly segmented to support pavement management so event tables and dynamic segmentation is used to create this feature class. After Pavement Carriageways are created via dynamic segmentation, they are dissolved by the PavementID field to create the tran_PavementSection feature class, which is easier to work with for GIS mapping and in Cartegraph software; it then represents each VDOT pavement section as a unique record/feature representation. The original VDOT pavement sections inventory always modeled streets as single lines, as a single table record. As discussed in the Carriageways metadata, the City models divided roads as double lines, if the street is physically divided, i.e. median. Therefore, Public Works' pavement management engineers have interatively gone through the exercise, with the support of GIS staff, to create new records in their pavement inventory for the "other-side-of-the-street," when divided carriageways were present. City pavement engineers treat divided streets as separate pavement entities. This feature class is considered to be a work in progress, as none of the City's pavement engineers has actually completed the process of translating VDOT pavement sections against carriageways. PavementCarriageways are subtyped for arterial, collector, and local street types.
