An advanced security system integrated with RFID based automated toll collection system

In the developing countries many crimes are happening at the highways and bridges. In this paper we have introduced a security feature which can resist the occurrence of those crimes. However, this system is based on RFID (Radio Frequency Identification) technology which replaces the traditional manual tolling system. In the existing automated tolling system RFID reader only detects the RFID card to deduct the toll amount according to the vehicle types. In our integrated system if the authority wants to block a certain type of vehicle or a specific vehicle, it can be done at the toll booth area. For this, a simple code text is sent to the system using GSM module and then the vehicle is blocked by not lifting the barrier even after deduction of the toll amount from the vehicle owner's prepaid based account. In addition, this can also be done to block all the vehicles at the toll booth area in the bridges in case of emergency.
