Singledriver

Singledriver is a term used in various domains to describe a driver operating a vehicle or system without additional operators. There is no single, universally accepted definition, and its meaning depends on context.

In transportation planning and policy, singledriver commonly refers to a single-occupant trip or to the practice of driving a vehicle with only one person aboard. The term is used in analyses of traffic congestion, vehicle emissions, and land-use planning. In this sense, singledriver rates (often called single-occupant vehicle rates) are contrasted with carpool or ride-sharing modes and can influence measures of transportation efficiency and policy targets.

In mobility services and autonomous systems, singledriver can describe a vehicle operated by one human driver, as opposed to fleets with multiple drivers or fully autonomous operation. The term may appear in studies of solo driving behavior, trip generation, and the design of service models that rely on a single operator per vehicle.

In information technology and hardware contexts, singledriver is not a standard technical term. When encountered, it is typically a coined or project-specific label for a driver component intended to be the sole controller of a device or subsystem. There is no agreed-upon formal definition within mainstream computing literature.

Etymology: the term combines "single" and "driver," indicating one operator or controller. Because usage varies, clarification is usually required when the term is encountered in a document.
