Abstract: The article presents the concept of using RFID technology in the process of locating public transport vehicles. Subsequent sections describe the types and capabilities of modern RFID systems, provide an analysis of available transponders, and discuss the placement of long-range readers and antennas within the localization system. The final part of the article presents the results of tests on the latest devices that can be used for vehicle localization.1. INTRODUCTION
Nowadays, vehicle localization aims to improve the transport process through automatic guidance to a destination, route optimization, identification of the vehicle’s location, and many other parameters related to the current conditions of vehicle movement. From a passenger’s point of view, information about the location of public transport vehicles is particularly important when planning and choosing a means of transport. Telematic systems providing such information are already being implemented and most often offer real-time information on the waiting time for a selected means of transport. No less important is the role that public transport localization systems play in documenting transport tasks commissioned to transport companies by municipal transport authorities.
Linking the scheduled and actual times of vehicles at designated stops can be an element of evaluating both the driver and the efficiency of a given company.
Since the 1990s, the most popular vehicle localization system has been the American GPS system. Despite its original military purpose, it was made available to civilian services with a certain disturbance (Selective Availability), which increased measurement inaccuracy. On May 1, 2000, it was turned off, which increased the system’s accuracy from 100 m to 20 m. The system was used despite the initially high price of receivers and the low performance of processors calculating the position. The development of technology, the removal of interference, and the drop in prices have led to mass production of receivers in recent years and their widespread use. Designers of telematic systems supporting travelers in cities are therefore eager to use this technology, counting on high efficiency with low expenditure on device infrastructure. (…)
