Описание (английский):

This document, based on ISO/TS 19468, specifies a platform-specific method for implementing data exchange among centres based on simple object access protocol (SOAP), supporting the EN 16157 series (DATEX II) for Push/Pull data delivery and service request/feedback collaborative intelligent transport system (ITS) services. This document defines the message rules and procedures for communication between transport information and control systems using XML (Profile B). This document clarifies how to package end-application messages and relevant data. The payload data definition used in specific end-applications and the exact structure of the content payload delivered in the messages are beyond the scope of this document. Rules and procedures for exchanging data-packets in lower communication layers are also out of the scope of this document. These functionalities can be implemented using generic protocols defined in the industry standards. However, this document does define how to use these protocols.

Overview

ISO/TS 14827-4:2022 specifies a platform-specific approach for exchanging transport information between centres using XML (Profile B) and SOAP web services. Based on the model-driven framework of ISO/TS 19468, it defines how to package and transport DATEX II (EN 16157) XML messages for Push/Pull data delivery and collaborative ITS services (CIS). The document focuses on message rules, WSDL/XSD bindings and SOAP-based Platform-Specific Models (PSMs) for patterns such as Snapshot Pull, Snapshot Push, Simple Push and Stateful Push. Payload content structure and lower-layer communications are explicitly out of scope.

Key topics and technical requirements

Message packaging and SOAP mapping: Defines WSDL operations and XML Schema (XSD) structures (e.g., MessageContainer) to map platform-independent models (PIMs) into SOAP-based PSMs.
Exchange patterns supported: Snapshot Pull, Snapshot Push, Simple Push, Stateful Push and collaborative ITS services (Simple CIS / Stateful CIS).
Model-driven approach: Uses ISO/TS 19468 PIM-to-PSM mapping rules to convert UML-defined functional exchange profiles (FEP + EP) into SOAP WSDL methods and data types.
Web service options: Static discovery (no UDDI); service descriptions published (ISO standards site). Security/encryption approaches are negotiated between supplier and client.
Security considerations: Recommends using established WS-Security mechanisms (XMLDSG, XMLENC, SAML, XACML) but leaves specific profiling (algorithms, tokens, policies) to implementers.
Conformance: No formal conformance tests; compliance achieved when exchange data follow the messaging rules in the specification.
Annexes: Includes schema and WSDL examples and an informative profile for "Snapshot Pull with simple http server".

Applications and who should use it

Traffic management centres and control systems implementing interoperable data exchange across regions or organizations.
ITS system integrators and software vendors building SOAP-based interfaces to support DATEX II XML payloads.
Municipalities and transport authorities coordinating real-time traffic information, variable message signs (VMS) and collaborative ITS services.
Consultants and solution architects mapping PIM-level designs to platform-specific SOAP/WSDL deployments. Practical uses include standardized push/pull of traffic events, congestion data, service requests and multi-actor orchestration for traffic management.
