ISO 24097-1:2017

Overview

ISO 24097-1:2017 - Intelligent transport systems (ITS) - Using web services (machine‑machine delivery) for ITS service delivery - Part 1: Realization of interoperable web services - defines a Service Oriented Architecture (SOA) for creating interoperable web services in the ITS domain. The standard prescribes a metadata‑driven approach so service behaviour is described at a higher abstraction level (WSDL, WS‑Policy), enabling auto‑generation of both service requester and service provider components. It covers the typical web service scenario: service provider, service requester, and a registry (publication/discovery via UDDI and endpoint references).

Keywords: ISO 24097-1:2017, Intelligent Transport Systems, ITS web services, SOA, interoperable web services, machine-to-machine.

Key Topics and Requirements

• Service Oriented Architecture (SOA): Foundation for interoperable ITS web services across heterogeneous systems.
• Metadata‑driven service description: Use of WSDL for interface description and WS‑Policy for operational requirements so tools can auto‑generate client/provider code.
• Service description layer: Rules for WSDL usage (including WSDL 2.0 evolution, versioning and multiple WSDLs), policy description, and addressing (EPR).
• Quality of Service (QoS) layer: Requirements and recommendations for reliable messaging, security, and transaction support.
• Messaging layer: XML/SOAP message structure, SOAP 1.2 considerations, and transmission optimizations (e.g., MTOM references).
• Service publication/discovery: Use of UDDI for registry interactions, service registration stacks and discovery workflows.
• Conformance and notation: Definitions of terms, conformance criteria, and normative annexes (WSDL evolution and syntax).

Practical Applications and Who Uses It

Practical applications include:

• Cross‑agency traffic management integration
• Route guidance and traveler information services
• Freight and logistics system coordination
• ITS-to-non‑ITS integrations (e.g., homeland security, environmental monitoring, commercial services)

Primary users:

• ITS system architects and integrators
• Software developers implementing ITS web services
• Transport authorities and agencies procuring interoperable ITS solutions
• Vendors building compliant ITS service platforms and registries

Benefits: accelerates deployment, improves interoperability across heterogeneous platforms, enables reuse and automation of service components, and simplifies integration with non‑ITS systems.

Related Standards

• W3C recommendations (WSDL 2.0, SOAP)
• WS‑Policy (OASIS/W3C)
• UDDI specifications for service registries
• ISO/TR 24097‑2 (example‑based companion guidance)

ISO 24097-1:2017 provides the architectural and metadata rules to ensure ITS web services are interoperable, discoverable, and secure-essential for scalable, machine‑to‑machine transport service ecosystems.
