Positioning estimation in public transport systems by leaky coaxial cables

In recent years, indoor positioning has become more and more important for industrial and commercial usage. Advanced approaches using leaky coaxial cables (LCX) not only for radio coverage have been developed. This paper deals with the application of LCXs for indoor localization in a public transport test scenario, run by the Fraunhofer Institute for Transportation and Infrastructure Systems IVI Dresden. In this scenario different systems were tested in a real-vehicle environment and compared to each other. In addition those results are contrasted with a synthetic indoor-test carried out in a corridor of the University of Applied Sciences Dresden, in the following referred to as "academic" scenario. Furthermore, the positioning accuracy, which could be achieved by using standard LCXs and two reference systems are demonstrated.
