Abstract

This invention pertains to the use of RFID (Radio Frequency ID) technology in Vehicle'"'"'s Number plates that can be issued by the Motor vehicle administration of the respective state governments. This RFID'"'"'s will be communicating with the Intelligent Traffic signaling system to efficiently handle traffic.

The same RFID'"'"'s can also be used to store the owners information along with critical medical information like blood group, primary physician'"'"'s name and contact. This life saving information can be used to help the Police and Paramedics to save the life in trouble with no delay.

The active radio frequency signals transmitted from the above RFID'"'"'s can be used to switch the traffic signals ON/OFF to get the life in trouble to hospital on time.

Claims

1. A method by which the traffic is regulated more efficiently by utilizing the unused signal time in any traffic signal. An electronic device fitted in the traffic signal will read and analyze the data from the special RFID (Radio Frequency ID) enabled “

Number Plates” and

switches the signal utilizing the unused signal time.

The intelligent electronic device in the traffic signal will cut short the time slice, if it finds there is no vehicles to utilize the time slice;

switching will happen immediately to utilize this unused time slice. This method of switching will allocate more time for high traffic and less time for the low traffic directions. No need for any clock based signal pattern change.

Based on the type and the count of these RFID'"'"'s the traffic signals will alter its switching time to clear up traffic and maintain clear and smooth traffic flow.

5. The method of claim 1, wherein said the intelligent processor realizes that there is no vehicles to utilizes the time slice

8. The method of claim 1, wherein said traffic signal processor communicates with the tag'"'"'s (Number Plates) RFID.

9. The method of claim 1, wherein said traffic signal processor counts and analyses the tag RFID'"'"'s including the priority data

2. A method by which the vehicles are tracked by the traffic signals using RFID enabled tags.

6. The method of claim 2, wherein the processor calculates the demand for the under utilized time.

3. A method by which the deadly traffic violations like “

Running red Light”

can be controlled by recording the violated vehicles and can be ticketed

7. The method of claim 3, wherein the intelligent processor allocates the unused time to the high traffic direction.

4. A method by which RFID readers fitted to the Law enforcement vehicles can easily get the information about the vehicles even in the absence of satellite communication and wireless technology.

10. A system comprising:

Each direction of traffic signal has a separate transponder to read vehicle'"'"'s RFID'"'"'s which will feed the data to the intelligent processor. The processor will analyze the data and switches the system locally.

11. An algorithm can be defined for the switching mechanism with in the same traffic signal or can be synchronized with the other traffic signals. This algorithm evaluate the count and the priority level of the tags (Number Plates) to justify the switching needs.
