The DiMo‑OMP project, titled “Digitalized Mobility – the Open Mobility Platform,” set out to create a fully integrated service chain for travel planning, booking, and execution that delivers consistent and transparent mobility information to users. The platform is intended for use in the Karlsruhe region, where the company INIT GmbH will handle booking and ticketing through the MOBILEvario product, which connects mobility providers via open interfaces. The overarching goal is to enable seamless interaction between public transport operators, private mobility services, and end‑users by providing a common, formally specified interface layer.
The technical work of the project is organized into several work packages. In the first phase, FIT led the development of a process and supporting tools for the formal specification of interfaces (AP 1.1). INIT contributed by analysing requirements, reviewing the process and tools, evaluating their suitability, and participating in milestone reporting. The second work package (AP 1.2) focused on tools for documenting formally specified interfaces, with a similar contribution from INIT in requirement analysis, review, and evaluation. The third package (AP 1.3) addressed tools for implementation, testing, and free certification of formally specified interfaces. Here, INIT performed reviews of the tool implementation, evaluated the tools, and tested them for usability and functionality. Across all three packages, the emphasis was on ensuring that the tools met the VDV (German railway association) requirements, drawing on INIT’s extensive experience with large, complex IT systems in the public transport sector.
Subsequent work packages expanded the platform’s scope. AP 2.1 created cooperation scenarios for the Open Mobility Platform, while AP 2.2 extended the role model to accommodate new stakeholders. AP 2.3 defined and documented user requirements. In the third phase, AP 3.1 specified the platform’s modules, AP 3.2 defined interfaces to external systems, and AP 3.3 specified internal interfaces between modules. The specification of external interfaces (AP 3.2) involved setting goals, outlining methodology, and producing results that align with the platform’s integration strategy; INIT’s participation ensured that the specifications reflected real‑world booking and ticketing needs. AP 4.1 demonstrated the tool‑supported development process for interfaces, and AP 4.2 showcased the fully functional OMP. Finally, AP 5.1 produced standardization proposals and documentation to support broader adoption.
Performance metrics were not explicitly reported in the available excerpts; however, the tools were evaluated for usability and functional coverage, and the platform’s design was validated through demonstrations that confirmed its ability to support formal interface specification, documentation, implementation, testing, and certification. The project’s scientific prospects include advancing formal methods in mobility service integration, while its economic prospects hinge on the platform’s potential to streamline booking and ticketing processes for operators and to enhance user experience through consistent information.
Collaboration among partners was central to the project’s success. FIT led the technical work packages, while INIT GmbH provided domain expertise, particularly in booking and ticketing systems, and contributed to requirement analysis, reviews, evaluations, and testing. The project also involved the VDV and other German initiatives, ensuring that the platform met national standards for public transport. The initiative was funded through a German federal program focused on transport and digital infrastructure, and it spanned multiple years, culminating in a final report that outlines the platform’s architecture, tools, and demonstration results. The report also discusses the platform’s potential for standardization, documentation, and future research and development, positioning DiMo‑OMP as a foundational component for open mobility services in Germany.
