Leveraging RFID for Road Safety Sign Detection to Enhance Efficiency and Notify Drivers

With exponentially growing pollution along with unfavorable natural conditions like snow and fog, the menace of road accidents has increased because most people will not be able to clearly view the safety board signs. Furthermore, it generally gets collected in most western countries which enhances the hindrance of these essential signs. The proposed solution makes use of Radio Frequency Identification (RFID) technology with the help of IoT to forward real-time warning messages to the drivers. In this system, an RFID reader is attached inside a vehicle and passive RFID tags are mounted on road safety signboards. If a vehicle falls in the range of the tag, it permits its reader to transmit the message alert of the tag towards the reader that then shows the warning to the driver. Hence, the system reduces the risk of accidents in harsh environments. The system has multi-lingual audio alerts, which it transmits through speakers and gives visual notice through a display screen; the multilingual audio output can be exploited to break the language barrier between various regions. The use of solar panel makes the system more energy efficient. This enhances road safety significantly and uses traditional signboards on roads along with RFID technology. Use of modules such as GPS and GSM modules allows for real updating of a vehicle's location in the cloud and, therefore, enhanced warnings and prevention of accidents. Besides this improvement in road safety, this solution also ensures environmental sustainability possibly by reducing emissions because of accidents and wastage of resources. The data collected through this system has been useful in studying the pattern of traffic and thereby adding towards more efficient and environmentally benign transportation systems. Quick and accurate notification to the driver aids in developing intelligent vehicle networks to make roads safer and sustainably used.
