- Two early software systems AVRIS (2000) and SIJPRIS (2009) have implemented a nationwide IT database schema that corresponded to the early version of Transmodel conceptual model. Technically, the AVRIS system was a desktop application and SIJPRIS was a distributed information system developed by the Slovenian Roads Agency (public transport authority in Slovenia, part of Ministry of Transport at that time) primarily for the management of the public inter-urban (long distance) bus transport. The system supported public transport authority tasks (management and registration of public transport infrastructure including stop place model and scheduled services model) and concessioners’ tasks (timetables proposals, periodical reporting about financial figures, number of passengers transported) stipulated by the law. Data exchange within SIJPRIS was implemented through a web service, using XML documents formatted according to own XML schema called TransportXML.org.
- Since 2017 a national integrated public passenger transportation system (IJPP, http://ijpp.si ) is in operation. It integrates all public transportation operators in Slovenia, including the national railways, to provide a unified ticketing & fare collection system. With 37 bus and one national railway operator, the IJPP deploys more than 1500 automated fare collection and validation terminals. By using unified ticketing users can travel across the country, regardless of the transportation provider. Ticket validations are performed with contactless cards.
The backoffice system consist of the three modules:
- public transport infrastructure (infrastructure points and links, stop places, zones, interchanges etc.)
- timetables (timing information and a tool for creation of timetables)
- management analytics and reporting (set of tools, which enable different public transport data views (i.e. temporal data, financial figures, number of passengers transported, number of kilometers driven (per PTO, per vehicle etc.), number of fares sold, etc.) taking into account linked passenger validations on terminals).
The IJPP system was built on the experiences from the previous AVRIS and SIJPRIS systems. It adopted the Transmodel-like conceptual database model (see Figure 1). However, the model does not yet consistently separate infrastructure, timing and service pattern layers as suggested in Transmodel.
Components of the IJPP system (Figure 2) are: IJPP database and the three PT systems (PT journey planner, national PT timetables, national PT infrastructure (daljinar).
- Based on the IJPP, a national journey planner was developed, which integrates all public transport in Slovenia (urban, inter-urban and rural travel, long distance travel): http://www.jpp.si
