RFID based Vehicular Positioning System for Safe Driving Under Adverse Weather Conditions

The radio frequency identification (RFID) technology for sensing has generated interest in the smart roads sector. Adverse weather conditions are often the cause of road accidents and signal interference, necessitating the development of RFID technology as precise road markers. This paper demonstrates a novel use of RFID technology along with global positioning system (GPS) location data as precise electronic road markers. A log periodic bowtie antenna design with broad bandwidth was fabricated upon an FR-4 substrate and implemented within concrete grooves in an asphalt road. In this framework study, the measurements between the tag and interrogator setup were carried out during snow or ice, sunny, and rainy situations. The results received by the interrogator from the tag demonstrate that the design is less susceptible to signal interference, possessing a quick tag response with a good signal strength. The proposed RFID marking technology can be used to enhance road safety and enable autonomous driving under all weather conditions.
