Name: HPMS_PassingSight

Display Field: EventID

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: The Idaho Transportation Department's (ITD) Roads and Highways Road Network Linear Referencing System (LRS) HPMS passing sight event polyline feature class identifies the proportion of each sample section where adequate sight distance exists for safe vehicle passing in the inventory direction. This measure reflects geometric and topographic roadway characteristics that affect driver visibility and passing opportunity.Values represent the percentage of total section length that meets or exceeds FHWA-defined minimum passing sight-distance criteria for the prevailing design speed. The dataset is used in safety evaluations, highway investment modeling, and roadway performance analyses. It is updated annually as part of ITD’s Highway Performance Monitoring System (HPMS) submittal to the Federal Highway Administration (FHWA).
