Abstract

A method and system is disclosed for detecting one or more wrong way drivers using one or more active or passive Radio Frequency Identification (RFID) tags installed in vehicles. If two or more RFID tags are detected in reverse order by two or more RFID readers, the method and system determines that a vehicle is travelling in a wrong direction and activates an alert.

Method and System for Detecting Wrong Way Drivers Using Radio Frequency Identification (RFID)

Disclosed is a method and system for detecting one or more wrong way drivers using one or more active or passive Radio Frequency Identification (RFID) tags installed in vehicles. If two or more RFID tags are detected in reverse order by two or more RFID readers, the method and system determines that a vehicle is travelling in a wrong direction and activates an alert.

FIG. 1 illustrates a process for detecting the one or more wrong way drivers using the one or more RFID tags in accordance with an embodiment of the method and system disclosed herein.

Figure 1

In accordance with FIG. 1, the method and system utilizes three or more active RFID readers in each lane of a road, spaced a certain distance apart (e.g. 30 feet apart) and powered by an energy source. The energy source can be, but need not be limited to, a solar power source. The three or more active RFID readers include a Central Processing Unit (CPU) such as a microprocessor to perform local computing. Further, the method and system includes two or more passive or active RFID tags in all vehicles, mounted at least in the front and rear of the underside of the vehicle with appropriate RFID numbers (e.g. xxxxxxxx-F for the front tag and xxxxxxxxx-R for the rear tag).

The method and system enables an active RFID reader on the road to read the closest RFID tag of a vehicle first in order to check the number. For example, if the first RFID tag read is -F and the -R RFID tag of the vehicle is read next, then the method and system determines that the vehicle is travelling in the correct direction.

If the first RFID tag of the vehicle read is -R and one of the next tags is -F, the method and system logs the information using a CPU. If a second set of RFID readers down the road also detects the two passive or active RFID tags of the vehicle in reverse
