INTRODUCTION :
The automated toll gates are the application of both the concepts of road pricing and intelligent transport system.Earlier motorists used to wait at a toll booth or a plaza to pay a machine or a collector for using a particular toll road.But it is not so in the case of a automated toll gate.Here the motorists need not stop or even reduce the speed of their vehicle.The whole process is completely automated.Road pricing is a type of tax sought by revenue starved governments because in most cases it is virtually impossible to create a market for roadway services.It is a type of public-private cost recovery partnership.
INTELLIGENT TRANSPORT SYSTEM :
Intelligent transport system is a broad range of diverse technologies applied to transportation to make systems safer, more efficient, more reliable and more environmental friendly without necessarily having to physically alter existing infrastructure. The technologies involved in Intelligent transport system are
Sensor and Control technology
Communications and computer informatics.
Intelligent transport system makes it possible to implement a number of government regulations and processes like toll collections, customs immigration & clearance and transport safety compliance.
ELECTRONIC TOLL COLLECTION :
Automated toll gates (or) Electronic toll collection (ETC), an adaptation of aircraft "identification friend or foe" technology, aims to eliminate the delay on toll roads. It is a technological implementation of a road pricing concept. It determines whether the cars passing are enrolled in the program, alerts enforcers for those that are not, and debits electronically the accounts of registered cars without their stopping, or even opening a window.
