HPMS Faulting

The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) HPMS faulting event polyline feature class represents the difference in elevation between adjacent concrete slabs at transverse joints on rigid pavements. Faulting occurs when one slab edge settles or rises relative to the next, typically due to load transfer inefficiency or erosion beneath the pavement. This measurement helps assess ride quality, structural condition, and pavement serviceability. Data is collected through field measurements or automated pavement condition surveys and is reported as the average fault height per slab joint in inches. Faulting data is used by engineers, pavement managers, and analysts to evaluate performance trends, identify maintenance needs, and model the progression of joint distress. It is maintained as part of ITD’s Highway Performance Monitoring System (HPMS) submittal process to the Federal Highway Administration (FHWA) and updated annually from the pavement condition inventory. 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《道路与公路》道路网络线性参考系统（Linear Referencing System, LRS）公路性能监测系统（Highway Performance Monitoring System, HPMS）错台事件折线要素类，表征了刚性路面横向接缝处相邻混凝土板之间的高程差。当一块板的边缘相对于另一块板沉降或抬升时便会产生错台，这通常源于传荷效率低下或路面下方侵蚀。该测量指标有助于评估行驶质量、结构状况与路面使用性能。 数据通过现场测量或自动化路面状况调查采集，以每个板缝的平均错台高度（单位：英寸）进行报告。错台数据可供工程师、路面管理者与分析师用于评估性能趋势、识别养护需求以及对接缝病害的发展过程进行建模。 该数据集作为ITD向美国联邦公路管理局（Federal Highway Administration, FHWA）报送的公路性能监测系统（HPMS）流程的一部分进行维护，并每年根据路面状况清单进行更新。本图层为《道路与公路》的导出数据，仅包含线性参考系统（LRS）中的有效记录，即当前的“工作”记录。如需获取静态发布数据，请参阅存储于以下网址的记录：https://www.fhwa.dot.gov/policyinformation/hpms.cfm。本内容项为公路性能监测系统（HPMS）权威要素图层的子图层。元数据（Metadata）
