TITAN/2 Deliverable 3.2: SPECIFICATION OF ENHANCEMENTS OF TRANSMODEL V.4.1.1

Executive Summary

This deliverable comprises the preliminary results of the enhancement and harmonisation process for the reference data model for public transport, Transmodel, within the first contract of the TITAN/2 project.

In the first chapter, a short introduction about the objectives and the planned enhancement and harmonisation process is given.

The second chapter is the main part of this deliverable. It comprises four proposals for enhancements. The presentation of the proposals is derived from internal reports of TITAN/1 and TITAN/2. In this presentation the results of a first harmonisation step (discussion in the Data Model Management Group (DMMG) and principle decision on integration into Transmodel) are incorporated. Some not (yet) agreed parts of the proposals are also presented to keep the integrated whole of the proposals, but these are marked as parts still to be discussed.

The first proposal is dedicated to the Real-Time Control extensions to the Transmodel. It has taken into account the methods used by the urban transportation networks in Germany, in France, in Greece and in Italy. This proposal contains the main parts of the proposal presented by the Extension Group 1 (TITAN/1) in the internal report "Extensions to Real-Time Control".

The second proposal contains the agreed parts of the proposal presented by the Extension Group 2 (TITAN/2) in the internal report "EG2: Multi-Modal Operation - Proposals for Data Model Extensions". Main objective of this proposal is to enrich the existing Transmodel structures with view to the needs of a multi-modal public transport environment, including the transport modes most commonly used in urban and regional public transport in Europe.

The network model part of Transmodel is the focus of the third proposal. It contains the agreed parts of the proposal presented by the Data Model Management Group in the internal report (TITAN/2) "Data Model Management Group - Extensions of the Network Model". This proposal, created by a special TRUST-task force, describes a proposal to extend and enrich the existing network model, as defined in the current Transmodel version, to cover the complexity of various different network descriptions and the coherence between these different layers.

The last proposal is dedicated to the version management in Transmodel. This proposal is still in work, so in this deliverable only a draft of the two proposed approaches is given. The first approach is very elaborated. It is based on common approaches and generic concepts. The second approach is only a short draft. This approach is a more context-specific solution with the objective to integrate as much as possible from the existing Transmodel, and is more closely related to the concepts used for version management in practical implementations, for instance in the TITAN pilot sites. Both approaches are not contradictionary, in fact they have many similarities.

The last chapter contains a short conclusion and summarizes the next steps of the enhancement and harmonisation process for the reference data model for public transport, Transmodel, within the second contract of the TITAN/2 project.

The appendix comprises the data dictionary entries of the four proposals.
