Overview
ISO/TR 22625:2025 - Intelligent transport systems - Mobility integration - Physical and functional view provides a common physical and functional architecture for integrated mobility services (MaaS and MOD). Building on the role and responsibility models in ISO/TR 4447 and ISO/TR 7878 and the vocabulary in ISO/TS 14812, this Technical Report maps enterprise roles (Mobility Service User, Mobility Service Provider, Transport Service Provider) to the physical systems, devices and functional objects that enable interoperable, publicly available transport services. The document aims to support a worldwide, convergent concept for multimodal, integrated mobility.
Key topics and technical emphasis
- Physical view: identification of physical objects (central systems, personal equipment, on‑board equipment) and their information exchanges within an ITS architecture.
- Functional view: abstract functional objects and their logical interactions; allocation of functions to physical objects.
- Four core use cases:
- MSU requests, books, uses and pays for a mobility service (end-user interactions).
- MSP manages and provides mobility services (service orchestration, product definition).
- TSP manages and provides transport services (vehicle and service operations).
- TIO manages transport infrastructure (infrastructure provisioning and operation).
- Enterprise relationships: agreements and expectations between enterprise objects; definitions of commercial rule, pricing rule, mobility service product, and transport service product.
- External systems: data security, positioning, communications, data management, payment service providers (PSP) and electronic fee/fare collection systems.
- Focus on interoperability, multimodal integration, and mapping existing implementations to a common model.
Practical applications - who should use it
ISO/TR 22625:2025 is intended for:
- Transport authorities and regulators designing policy and interoperability requirements for MaaS/MOD.
- Mobility service providers (MSP) and transport service providers (TSP) planning system architecture, interfaces and service products.
- ITS architects, system integrators and software developers implementing central systems, mobile apps, on‑board equipment and back‑end services.
- Payment providers, tolling and fare management vendors integrating with mobility platforms.
Use cases include architectural mapping of existing systems, defining interfaces for multimodal trip planning, fare/payment integration, and aligning deployments with a world‑wide integrated mobility concept.
