Road are the access to the outside world or store around the corner. It takes farm produce to market and children to school. They are the conduit of life's activities; therefore they must be maintained and free from geographical obstacles. Thus, for the maintenance of these roads, tolls are made to collect taxes.

A toll road, also known as a turnpike or toll way, is a public or private roadway for which a fee (or toll) is assessed for passage. It is a form of road pricing typically implemented to help recuperate the cost of road construction and maintenance, which (on public roads) amounts to a form of taxation.

The tolls have existed since antiquity, collecting the fees from the passengers on foot, wagon or horseback.  But, due to the rise of automobiles their prominence increased rapidly, charging automobiles exclusively depending on their type, weight or number of axels.

The tolls are collected at points known as toll booths, toll houses, toll plazas, stations, bars, or gates. To cut costs and minimize time delay many tolls today are collected by some form of automatic or electronic toll collection equipment which communicates electronically with a toll payer's transponder. This automated toll paying system includes highly advanced automated toll plaza instrument which includes:

• Toll Traffic Lights: Toll traffic lights are of different dimension form 200nm to 300nm, installed before the exit barrier on the pole. It consists of Red and Green traffic signal lights that give the information to wait and go to the motorists.

• Overhead Lane Signs:  The lane control sign are an assembly of a Red Cross and a Green Arrow to inform the motorists whether that particular lane is open or closed and therefore the motorists can decide well in advance to divert on other lane. These signals as the name suggest, are mounted on the toll plaza on each lane, so that the motorist can view lane control signs from quite a far distance.

• User fare Display: The User Fare Display (UFD) is located in the toll lane in a position where it is readily visible to and readable by the users from the pay point. The Display has the primary purpose of informing the user of the vehicle, classification entered by the toll collector and the toll to be paid. It however also conveys ETC balance information & low balance warnings, public relations and seasonal messages depending on what should and what should not be displayed by the Concessionaire.

• Fog Light: Fog Light is located on the bull nose (crash barrier) in the position where it is readily visible to the user of the toll road.

• Manual Barrier: In order to prevent traffic to flow in the closed lane, Manual barrier are used at the Entry for each toll plaza lane. There are also used at the reversal lanes of the toll plaza.

Conclusion:  The automated toll plaza equipment plays an important role by helping people in controlling and guiding the means of transportation. These are highly advanced; and easy to manage and have changed the demography of Indian roads by making it technologically advanced and hi-tech.
