A toll bar is a physical barrier or gate erected across a road or passageway, typically at a designated point of entry or exit, to regulate and collect fees from vehicles or individuals using the road or passageway. It is an infrastructure used for toll collection purposes.
The primary function of a toll bar is to control and monitor the movement of vehicles entering or leaving a specific area or facility. It ensures that the appropriate toll charges or fees are collected before allowing passage. Toll bars are commonly found on highways, bridges, tunnels, and other important transportation routes where there is a need for revenue generation and traffic management.
Typically, toll bars consist of a sturdy, horizontal beam that can be raised or lowered to open or close the road or passageway. They are often automated and operated by toll booth operators or electronic systems that detect and process toll payments electronically, such as through electronic tags or cameras.
The fees collected at toll bars may vary depending on factors such as vehicle type, distance traveled, or the duration of road use. They are commonly used to finance the construction, maintenance, and operation of the infrastructure they regulate, ensuring safe and efficient transportation systems for users.
The word "toll bar" has its roots in the Old English language. The term "toll" comes from the Old English word "tol", meaning a tax or duty. It can be traced back to the Germanic word "tullam", which has the same meaning.
The word "bar" is derived from the Old English word "bearu", which meant a barrier or fence. This word later evolved to "barre", which referred to an obstruction or blockage.
The combination of "toll" and "bar" formed the term "toll bar", which originally referred to a physical barrier or gate placed across a road or passage. At these toll bars, toll collectors would collect fees or taxes from anyone using the road. Over time, the term "toll bar" has come to be associated with the toll booths or collection points themselves.
