| Abstract: Contains features representing Bridges, Traffic Cabinets, Crosswalks, Street Lanes, Loop Detectors, Parking Meter Poles, Pavement Markings, Pavement Stripes, Pedestrian Signals, Railroad Crossings, School Zones, Sidewalks, Traffic Signals, Traffic Signal Poles, Sign Mounts, Signs, Speed Humps, and Speed Limits. | |||
| Purpose: Transporation Assets were collected for use in supporting Public Works' Asset Management System and processes. With a GIS-based Asset Management System (AMS), these assets are used for spatial analyses and geographic visualization, supporting work coordination, asset replacement/planning, asset inventorying, and over-all management of Public Works assets. | |||
| Supplemental Information: From 2004 - 2007, Public Works' was engaged in the implementation of an Asset Management System (AMS). As part of the AMS implementation, Public Works' consultant captured imagery of the City's right-of-way (ROW) by deploying a GPS/camera equipped van which drove and took pictures throughout the City of Richmond ROW. The resulting imagery enabled stereo measurement software to be used to locate asset objects visible in those 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. Linear assets/information, i.e. lanes, sidewalks, pavement stripes, are linearly referenced (LRS) from Carriageway features, each of which serve as individual route features (percent along). Point assets do not use LRS, but they do have reference to Carriageway features and include a) intersection ahead and behind (IntersectionID), and b) route ahead and behind (StreetNameID), and c) distance ahead and behind (distance to intersections). These are provided to assist in potential uses of textual references for locating assets. Transportation Assets are tightly coupled to the Carriageways in the Centerlines dataset, in ways that permit queries and anlaysis of Public Works' assets by street name, section and address ranges. Point assets may also carry the IntersetionID of an Intersection feature that it is associate with, thereby enabling asset inventory reporting and analyses by City intersections. Some Transportation Assets have a "Condition" field that is populated with good, fair, poor, which were interpreted from the vendor, to be used for planning work responses. 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.
