Information and Communication Architecture of the Passenger Information System on the Railway Network of the Republic of Croatia

Abstract

HŽ Infrastructure Ltd is a company in charge of management, maintenance, and building of railway infrastructure which is obliged to provide the user with all relevant information on the departure and arrival of trains and possible delays. There are currently 545 official places (stops and stations) on the Republic of Croatia’s railway network. To implementing modern communication solutions in the function of informing passengers, it is essential to make a systematic analysis of the technical-technological ecosystem to connect all the elements and deliver information to passengers. In this paper, an analysis of the current state of telecommunication infrastructure and equipment of all official places on the Republic of Croatia’s railway network is made. Based on the analyzed data, the central system’s functions, the passenger information system’s conceptual architecture, and the way the system communicates with the vehicle are defined. The technical-technological requirements that end users must obtain accurate and real-time information can be implemented according to the phased introduction and upgrade of the system, which is visible in the passenger information system’s proposed conceptual architecture in this paper.KeywordsInforming passengersTelecommunication infrastructureInternet of ThingsSensor networks
