4.5 CEN TC278 – Interoperable Public Transport Fare Management System Architecture (IFMSA) 4.5.1 Description of the Standard CEN TC278 provides the basis for the development of a multi-operator/multi-modal interoperable Public Transport Fare Management System (IFM). The IFM system provides a reference functional architecture for electronic fare payment systems and identifies requirements that are relevant to ensure interoperability between the entities in the system. The IFM system addresses all the functions involved in the fare management process including: • Management of application(s) • Management of products • Security management • Customer management • Inspection/enforcement • Reporting and monitoring When completed, this standard will comprise several parts; currently only Part 1 is available in draft format. Part 1 describes the following main elements: • Identification of the different functional entities in relation to the overall fare management system • Definition of a generic model of IFM system describing the logical and functional architecture and the interfaces within the system and with other IFM systems • Use cases describing the interactions and data flows between the entities • Definition of the security requirements 4.5.2 Applicability to UTFS Effort Although IFM provides a well-defined model for the management of an interoperable transit fare collection system, it is an incomplete draft as of today. In its current form, IFM is a high level document and does not include the level of detail that APTA is looking for and therefore is not applicable to APTA’s scope of work. On a higher level, this document is useful in defining the components and entities involved in an electronic fare payment system as illustrated in Exhibit 4.5-1. Page 46
