Radio Freequency Identification Technology

The system is based in positioning a processor in the vicinity of the traffic signal controlled intersection. The processor is configured to store adaptable cycle times for the traffic signal. A Radio-frequency Identification (RFID) reader is mounted in the vicinity of the traffic signal, which communicates with the processor and interrogates the RFID tags on each RFID-tagged vehicle at the roadway intersection. The RFID reader in combination with the processor counts the number of RFID-tagged vehicles present in each traffic flow direction at the roadway intersection.Congestion problem is increased in a dramatically way due to increased population and travel means. The associated consequences for this problem made it extremely bothering. Since the expansion of the traffic network is no longer a socially attainable solution, the existing control systems have to be used in a more intelligent way, in order to increase the traffic throughput and decrease total travel times. Intelligent transportation systems ITS had been developed to overcome the congestion problem, undertake to identify the real number of cars present in the street, but there is some limitation arises (existing of blind spots, counting the car more than one and such problems). So the necessity for smarter ITS technology based on an elegant way to identify the real number of cars is emerged via using RFID technology, Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. RFID technology does not require contact or line of sight for communication. The system is based in positioning a processor in the vicinity of the traffic signal controlled intersection. The processor is configured to store adaptable cycle times for the traffic signal. A Radio-frequency Identification (RFID) reader is mounted in the vicinity of the traffic signal, which communicates with the processor and interrogates the RFID tags on each RFID-tagged vehicle at the roadway intersection. The RFID reader in combination with the processor counts the number of RFID-tagged vehicles present in each traffic flow direction at the roadway intersection. The processor may be configured to interact with the other traffic signal processors at other intersections so that the traffic signal operation can be coordinated. This innovation enables tracking a vehicle in the absence of GPS or a cell phone, risky traffic violations like running a red light can be detected and the owner identified and other applications may be developed
