ABSTRACT : ABSTRACT AUTOMATIC TOLL TAX SYSTEM Automatic toll tax project is designed, using Atmel 89c51 microcontroller & discrete components. Heart of the project is an IR transmitter and receiver modules, these strong powerful modules transmits 38khz strong IR beam, has a range of more than 15 feet are sufficiently enough for our project. I have designed this project as a simple implementation of the toll collection process automatically in a model form. This should not be considered as a real toll collection system which require much more considerations, tests and huge amount of money, before they are actually put into use .
: However this project gives enough guidelines for the actual development of the toll collection system. For the sake of simplicity , we have to make coin box exactly same as used in PCO coin box machine fixed on railway station or else where. We have to make two coin size holes one for one rupee, and other for five rupee coin. You have to fix up coin sensors on these holes, one sensor should be fixed for five rupee coin and one sensor for one rupee coin.

OPERATION : OPERATION When light vehicle is detected, one rupee sensor led will glow also the device will speak out " please enter one rupee" in three languages. if the coin is inserted, it will stop asking for the coin and gate will open. when the vehicle crosses other side of the gate the gate will close. also the count value on the lcd will be updated . operation is similar for heavy vehicle where the device is going to ask for "five rupee coin" the project will maintain the complete details of all the vehicles crossing that way.. so no vehicle can cross without paying.

ADVANTAGES: ADVANTAGES Fuel Saving. Reduced waiting time. Reduced traffic drain on highways tolls.
APPLICATIONS: APPLICATIONS By using more advanced technologies with ATT, it can directly connected to the server. Through this we can reduce man work and can be operated fastly.
LIMITATIONS: LIMITATIONS The only limitation of ATT is that is unable to detect whether the vehicle is light or heavy. To overcome this limitation we have to make separate lane for light vehicles as well as for heavy vehicles.
