Summary:This paper presents results of a research on the possibility to collect anonymous data regarding the level of service in public transport and indoor localization/route guidance. Wireless technology (Wi-Fi) is employed to detect and trace mobile devices carried by travelers. A study on the wireless propagation in different environments, such as metro stations and trains has been performed, in order to determine a theoretical model and an optimal placement of sensors. The solution can also serve as back-up system for locating vehicles on their path. Due to the complexity and extension of the subject, the paper has been divided in two parts. The first part of the paper presents the overall solution proposed, a study on the state of art, conditions, and models regarding Wi-Fi signals propagation, accompanied by a set of experimental tests. The second part of the paper is focusing on a deeper research on the conditions of propagation, including the analysis of latency and influence of people from the platforms on the signals' propagation. Also, the overall architecture of the proposed system and a new model for indoor propagation in underground metro stations are provided.
