Provided are an apparatus and a method for providing position information
and gathering information using Radio Frequency Identification (RFID).
The apparatus includes: a plurality of RFID tags, driven by a radio
frequency transmitted from an RFID reader installed in the vehicle, for
providing stored tag information in order to provide current position
information to the vehicle; a plurality of sensor nodes for sensing the
time point when the RFID tags are driven and transmitting the sensed
information through a sensor network; and an information gathering server
for gathering and processing the information sensed by the sensor nodes,
where at least two RFID tags and one sensor node are configured in
groups, and the groups are installed at predetermined intervals on each
lane of a road.
