About the project JSDV

Project JSDV – unified PT data system (2011-2013)

The main partner – Centrum dopravního výzkumu, v.v.i. (Transport research centre)
The co-partner – Chaps, spol. s r.o. (EU best multimodal journey planner provider, awarded in 2012)

The project is financed by Technology Agency of the Czech Republic and the state budget.

Brief project introduction

The current situation in the Czech Republic regarding information systems in public transport operating with real-time data is based on proprietary and non-compatible solutions. So the possibility of sharing important information among the systems is very limited; even in the case when vehicles cross the borders of different regions having the connection in the other region (so called foreign vehicles). Regarding the on-going technological progress and the increasing number of implemented systems the project for unified PT data system (JSDV) has been called.

The scope of the project is a conceptually built-up telematic system with a standardized interface that enables the integration of data in real time for the benefit of carrier/system organizing several carriers (Integrated transport system (IDS)) or operator/manager of the road/rail. The project has designed and pilot operated “the Central system with PT real time data (CISReal) that should be operable in national scale. The title of the system comes from already operating system (CIS JŘ) that is the complex database of static/planned journey schedules. The basics of CISReal is to share real time operational data with the possibility to integrate the systems already running (but not in a standardized manner) and support official implementation of the guidelines for setting up the terms and conditions for new unified standard (how to provide the data) and the duty to share specific data with the central system (CISReal). The system is designed in a unique way that respects the already implemented and operated aspects of the Czech Republic (existing national predispositions) and also the basic specification and elements of EN 12896 TRANSMODEL and CEN TS 15531 SIRI (European interoperability). So, besides the pilot implementation the standard for existing systems of the carriers to share real-time data with the central system has been worked out as a national standard. This is the corner stone of possible future step-by-step implementation of CISReal into nationwide system.

The proposed solution takes into account the import of dynamic data from connected periphery systems that are to be paired with static data of CIS JŘ. The interconnection of the two kinds of data (real and planned) is made in a modular database of complex PT information (with the possibility to add functional services) with standardized interface for data sharing with third parties. The central system is to connect to adjacent systems to get the data from but also to share the data with all the participating systems.

The pilot operation is starting since June 2013, see the operation at.

The results of the projects are listed below:

  • Data format and content.
  • Communication data protocols.
  • Unified terminology.
  • Unified numbering.
  • Set-up of the architecture for data sharing.
  • Database of historical data creation for later analysis and better planning of public transport organization in national scale.

In the final version the system is ready for data sharing with foreign systems on the basis of SIRI specification.

The result enables the investors of information systems (organizers, carriers, transport operators) to:

  • Connect to Central system with PT real time data (CISReal).
  • Use the central system to get real time data about the movement of “foreign vehicles” on the monitored territory.
  • Share easily the information with external carriers.
  • Follow, in the future, the possibility of assuring the connections in national scale among the modes of transport.

The result enables the travellers to:

  • Search the journey in real-time on the single place (server) in national scale.
  • Use of smart mobile phones to look-up the connections.
  • Search alternative connections in the case of the delay.
  • Plan the journey within the journey (on-trip planning).
  • React effectively on unusual conditions on the route.
