Name: Mater Street Map Roundabouts

Display Field: Rtype

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This point feature layer represents roundabout locations extracted from the Master Street Map (MSM) maintained and managed by the Ada County Highway District (ACHD) in Ada County, Idaho. Each feature corresponds to an individual roundabout and include attributes such as roundabout type, street names and RAB type. Roundabouts serve as alternative intersection control devices designed to improve traffic flow, reduce conflict points, and enhance safety compared to traditional signalized or stop-controlled intersections. The dataset is intended to support transportation planning, traffic operations, safety analysis, intersection management, capital improvement programming, and public-facing mapping applications across the ACHD road network. Data was compiled and is maintained by the Ada County Highway District.
