 "description": "<DIV STYLE=\"text-align:Left;\"><DIV><P><SPAN>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.<\/SPAN><\/P><P><SPAN>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.<\/SPAN><\/P><P><SPAN>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.<\/SPAN><\/P><P><SPAN>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\u2019s Asset Management System (Trimble Unity Maintain / Cityworks).<\/SPAN><\/P><P><SPAN STYLE=\"font-weight:bold;\">Field Definitions / Attribute Overview:<\/SPAN><\/P><P><SPAN>This dataset contains key attribute fields describing each pavement marking asset.
