These assets include specialized lighting systems that are not associated with standard roadway streetlights or traffic signal infrastructure.Non-TS Alpha lighting assets consist of various facility-based lighting types, including but not limited to:Highway Bridge Lighting (HBRLITE) Highway Tunnel Lighting (HTUNNEL) Illuminated Signs (HILLSGN) Parking Lot Lighting (HPKLOT) Pedestrian Overcrossing Lighting (HPEDOV) Pedestrian Tunnel Lighting (HPEDTUNL) Soffit Lighting (HSOFFIT) Park Lighting (HPARK)These assets are grouped and managed using an Alpha classification system, where each asset is categorized by a standardized TYPE code representing its functional lighting application. Additionally, assets are associated with PCA (Project/Program/Circuit Area) groupings, which organize lighting systems into maintainable units for operational and maintenance purposes. Unlike conventional streetlight datasets, Non-TS Alpha assets often represent facility-based or system-based lighting installations (e.g., tunnels, bridges, freeway structures, pedestrian infrastructure), rather than individual pole-mounted lights.Field Definitions / Attribute Overview:This dataset contains key attribute fields describing our Non-TS Street Light assets.

Description: This dataset represents the locations and attributes of pavement marking assets maintained by the Los Angeles County Department of Public Works (DPW), Operational Services Division (OSD). Pavement markings include surface-applied roadway features such as symbols, legends, stop bars, crosswalks, text markings, and other traffic control devices that convey regulatory, warning, or guidance information to roadway users.Each asset record represents a single marking type, defined by a standardized marking code (MARKCODE), and may include a quantity of that marking within the defined asset extent. For example, an asset may represent multiple instances of the same marking type (e.g., multiple stop bars or symbols) grouped within a single record.Marking locations are defined using linear referencing along roadway segments, incorporating street names, cross streets, and directional distance measurements to establish the spatial extent of each asset.Attributes are structured to align with DPW asset management standards and include references to Caltrans Standard Plans, MUTCD classifications, and material and reflectivity properties. The dataset supports asset inventory tracking, maintenance planning, and integration with the County’s Asset Management System (Trimble Unity Maintain / Cityworks).Field Definitions / Attribute Overview:This dataset contains key attribute fields describing each pavement marking asset.

Description: This dataset represents the locations and attributes of Department of Public Works (DPW) pavement striping assets maintained by the Operational Services Division (OSD) within Los Angeles County jurisdiction. Pavement striping assets include roadway centerlines, lane lines, edge lines, bike lanes, and associated striping configurations used to regulate traffic flow, delineate lanes, and enhance roadway safety.Striping assets in this dataset represent the complete set of roadway striping elements for a given segment of roadway, rather than individual lines. Each asset captures the full striping configuration across the roadway cross-section, including centerlines, lane lines, edge lines, bike lanes, and associated features, as defined by the STRIPECODE.Striping assets are spatially segmented based on changes in roadway geometry and striping configuration. In particular, assets are split at locations where there is a change in the direction of the roadway centerline, such as curves, intersections, or transitions between roadway segments. This ensures that each striping asset represents a consistent and uniform configuration along its length.Within each segment, all striping elements are grouped together into a single asset record, allowing the STRIPECODE and its associated component fields to fully describe the roadway striping layout for that section.This segmentation approach aligns with DPW striping standards, where roadway striping is managed and maintained as a system of coordinated elements rather than as individual independent featuresThis layer was developed to support asset management, field maintenance operations, striping inventory tracking, and integration with the County’s Asset Management System (Trimble Unity Maintain / Cityworks).Field Definitions / Attribute Overview:This dataset contains key attribute fields describing each Pavement Striping Asset.
