RFID based Infrastructure to Vehicle Communication System for Road Sign Identification

Abstract

This paper produces an efficient, low-cost solution for communication between Infrastructure and vehicles by exploiting the passive UHF RFID features to deploy a scalable platform that overcomes the limitation of current technology GPS, WIFI and camera used in intelligent transportation system (ITS). The limitations are GPS inaccuracy, camera failure in bad weather, WIFI extra time handshake, and high deployment cost. The suggested system provides fast communication in real time that's required in warning message transmission between Infrastructure and vehicles, like speed limit warning and curve warning that the driver always misses or ignores. The proposed system contains a UHF RFID reader with a built-in antenna installed in the front pamper of the car connected to a microcontroller Arduino UNO by serial interface and a passive RFID tag deployed inside the road surface in the same line of the intended warning signal and this tag store the road information related to the warning signal. When the go over the RFID tag, it will retrieve its information, and a warning message will display on an LCD screen. This paper simulates all possible weather conditions and tries the system under four communication environments: water, dust, asphalt and free Air and compares the result accordingly.
