| Description | |||
| Abstract: Represents Pavement Striping. Pavement lines are used to denote the edge of travel lanes and to denote individual travel lanes. 1) Begin/End Striping: At the beginning/ending of each road, an initialization point will be measured in the center of the road. All pavement Striping features for the right and left sides of the road are attributed to the initialization coordinates. 2) Attribute Change: At locations where the pavement Striping begins, ends, or attribute information for the pavement Striping changes a point will be measured to denote the change location. If pavement striping change points occur at the same location for the left and right side of road only one set of coordinates will be used to denote the change. 3) Centerline Striping: Centerline pavement stripings are attributed to the right side of the road. 4) No Striping Present within Segment: If no pavement Striping is present on a road segment, no pavement Striping measurement will be recorded. Types of Pavement Striping include dashed and solid. The cumulative number of Striping features that occur at each change location is captured. | |||
| Purpose: To support the use of a GIS-based Asset Management System (AMS). Pavement Striping is used for spatial analyses and geographic visualization, supporting work coordination, asset replacement/planning, asset inventorying, mapping, and over-all management of these assets. Pavement Striping was provided with a "Condition" attribute (interpreted by the vendor's evaluation from the imagery) to be used for planning work responses. (Excellent, Good, Fair, Poor) | |||
| Supplemental Information: From 2004 - 2007, Public Works' was engaged in the implementation of an AMS. As part of the AMS implementation, Public Works' consultant captured imagery of the City's right-of-way by driving a GPS/camera equipped van throughout the City of Richmond, from which stereo measurement software was used to locate asset objects visible in the images. This type of terrestrial photogrammetry enabled technicians to interpret assets from the imagery and convert those assets into geographic coordinates. The majority of the asset types were collected in this fashion, and the inventory of both point and linear assets along the designated Carriageways were attributed and delivered to the City in GIS format. Pavement Striping is linearly referenced (LRS) from Carriageway features (each of which serve as individual route features (percent along)), and then converted into a feature class. Transportation Assets are tightly coupled to the Carriageways in the Centerlines dataset. This close relationshiop permits queries and anlaysis of Public Works' assets by street name, section and address ranges. 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.
