HPMS Present Serviceability Rating (PSR)

The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) HPMS PSR event polyline feature class represents a numerical rating of pavement ride quality and surface condition based on field observation. The Present Serviceability Rating (PSR) scale ranges from 0.0 (very poor) to 5.0 (excellent) and reflects the ability of the pavement to serve the traveling public comfortably and safely. PSR is primarily used for unpaved or local road segments where automated roughness measurements (such as International Roughness Index (IRI)) are not available. Values are determined through visual inspection or windshield surveys using standardized rating criteria. This dataset supports HPMS performance reporting, trend analysis, and maintenance prioritization, and is updated annually as part of ITD’s Highway Performance Monitoring System (HPMS) submittal to the Federal Highway Administration (FHWA). This layer is an export from Roads and Highways that represents only the active records within the LRS. These are current “working” records.

Metadata爱达荷州交通运输部（Idaho Transportation Department, ITD）的公路与道路路网线性参考系统（Linear Referencing System, LRS）下的公路性能监测系统（Highway Performance Monitoring System, HPMS）PSR事件折线要素类，是基于野外观测得到的路面行驶质量与表面状况的数值评级成果。当前服务性评级（Present Serviceability Rating, PSR）的取值范围为0.0（极差）至5.0（极佳），该评级可反映路面为出行公众提供舒适、安全通行服务的能力。PSR主要应用于未铺设路面或地方道路路段，这类场景通常无法获取自动化粗糙度测量数据（如国际粗糙度指数（International Roughness Index, IRI））。其评级数值通过遵循标准化评级准则的目视巡检或车载挡风玻璃视角巡检确定。本数据集可支撑HPMS绩效报告编制、趋势分析以及养护优先级排序工作，且作为ITD向美国联邦公路管理局（Federal Highway Administration, FHWA）提交的HPMS子项，每年更新一次。此图层为公路与道路管理系统（Roads and Highways）的导出产物，仅包含线性参考系统（LRS）内的有效记录，即当前的“在用”工作记录。如需获取静态已发布数据，请参阅存储于以下地址的记录：https://www.fhwa.dot.gov/policyinformation/hpms.cfm。本内容项为HPMS权威要素类的子图层。元数据
