Hierarchical Railway Traffic Model for Information Systems G.I.Daian, M.M.Santa, T.S.Letia Department of Automation, Technical University of Cluj-Napoca, (UTCN) Cluj-Napoca, Romania Ghita.Daian@infofer.ro Maria.Santa@aut.utcluj.ro Tiberiu.Letia@aut.utcluj.ro Abstract— The European Commission adopted a roadmap for the next decade to build a competitive transport system that will increase mobility, remove major barriers in key areas and fuel growth and employment. Passenger Information system is a component of rail system that can grow the quality of services on railway market. One of the major problems of these systems are the prediction of arriving train time to intermediary or final station. This paper proposes a solution for railway network modeled with a development of UML components. The component behavior is modeled by Delay Time Petri Net (DTPN). These models detail the railway network into stations and further represent the resources and the time spent on each resource to calculate the remaining travel duration. Every delay in railway network involves an update of the planned routes with new arrival time estimation. Keywords—componen model; railway traffic information, train traffic model, Petri net I. INTRODUCTION Railway passenger information systems are electronic information system whose primary purpose is the provision of real-time information relating to a train service and its adherence to a prescribed schedule both video and audio. Also they may offer the additionally information about the nature and causes of disruptions. Nowadays, the quality of railway transportation services depends on information systems. Both the passengers and freight transport can become more competitive in the market of transport services if offers an efficient information system. In this article the railway information system refers to passenger information system. Passenger information systems could provide only predictive information for trains that have begun their service. They do not extend these predictions to not started trains. It may be used both within the stations for displaying the information and remotely usually with a web browser or mobile device. The European Railway Traffic Management system (ERTMS) permits trains on service running to communicate through mobile communication standard GSM-R their current positions. This information will be completed with the published service timetable and the prediction time of how services will run in the next few minutes to hours. The information provided by real-time passenger information systems, bus services or the weather conditions can be used in other systems like passenger journey systems that manage the passenger’s journey requirements, and uses the information supplied to provide personalized journey experience. It is worth noting that there must be an actual value as individuals are willing to pay for systems that give access to real time data relating to their journey. These informations may be accessed via any electronic media, including: telephone, touch screen kiosks for self- service in customer office, web browsers, and smart phones or can be displayed on screens or led displays inside stations. At a station or stop the information provided by a railway information system refers to time predictions about the trains arrive, how closely they are running to timetable and possible general advice on current travel disruptions that may be useful to the passenger in understanding the implications for their travel plans. Others channels like mobile device, web, or info-kiosk will normally be set up to mimic the view from a station or stop or it may be linked to journey planners. Using such systems a passenger may plan the journey to take into account current circumstances such as cancelled services or excessive delays. II. RELATED WORKS Passenger information is one of the most important elements of modern transport systems. It can reduce the involvement of passengers in search of information, saving them time and increasing convenience. Traditional ways of informing passengers with timetables on paper are slowly replaced by solutions more convenient and efficient. Good passenger information system is one that using several media and provides quick and easy access to information in all places where such information might be needed in traveling. These requirements can be achieved by extending the passenger information to all locations where the passenger might get, from train, rail stations or e-media like web or mobile devices with access to internet, quickly presented independent of the location and edited in real time. In these systems, informations like the position on the route are collected from trains via GSM-R. The arrival delays
