Road Vehicles Identification and Positioning System

Abstract

Radio frequency identification (RFID) is untouched automatic identification technologies in which information can be transmitted by radio frequency. In this study, an RFID system which can determine the position and place of any desired vehicle is designed and developed. Microprocessor transmitter devices, on which the vehicle information is loaded, are placed on the vehicles. Receiver circuits are located at certain points in order to receive the RF signals sent by these transmitter devices. The communication of all the points with each other is maintained by connecting the receiver circuits via the internet. The functionality of the system is tested by performing receiver-transmitter experiments based on the various speeds and locations of the vehicles. According to the results obtained in the experiments, it is seen that the system designed in the study could be used in place of the GPS system for determining the place and position of vehicles, since it is more economical when compared to the GPS system.

Decision Support System for Robust Urban Transport Management

“…Therefore it is needed to solve a path generation problem, by finding the best destination point and the shortest route connecting with that vertex the current position v p which can be estimated based on the timetable or using a vehicle positioning system [16]. This route is calculated using the modified Dijkstra algorithm that excludes forbidden paths during the search by assigning infinite distances to vertices reachable by such a path.…”
