sweptpath
Swept path refers to the envelope traced by the outermost points of a vehicle as it follows a prescribed maneuver along a reference path. In road and traffic engineering, swept-path analysis is used to determine whether a roadway, intersection, or other facility provides sufficient space for a vehicle to complete a turn or maneuver without conflicts with curbs, medians, or other obstacles. The concept applies to a range of vehicle types, from passenger cars to buses, trucks, and emergency vehicles.
A swept path study begins by selecting a vehicle type and size and defining a reference path,
Swept-path analysis is used in designing intersections, roundabouts, driveways, parking layouts, loading docks, and service vehicle
As a planning tool, sweept-path analysis assumes standard vehicle configurations and steady-state maneuvers in a plane.
