Full title and description

St ISO TR 17424-2015 — Intelligent transport systems — Cooperative systems — State of the art of Local Dynamic Maps concepts. A Technical Report that surveys architectures, implementations and standardization activity related to Local Dynamic Maps (LDMs) for cooperative ITS and derives requirements, gap analysis and recommendations for further standardization and deployments.

Abstract

This technical report (ISO/TR 17424:2015) reviews the state of the art for Local Dynamic Maps (LDMs) used in cooperative intelligent transport systems (C‑ITS). It summarises high‑level LDM architectures from major projects and implementations, compares them with the ITS‑Station architecture, identifies functional, technical and legal requirements for a global LDM concept, performs a gap analysis against existing specifications, and makes recommendations for standards development organizations and decision bodies. The report is informative and does not mandate any single commercial implementation.

Scope

ISO/TR 17424:2015 scopes a broad survey of Local Dynamic Map concepts for cooperative ITS. It examines existing LDM implementations and research projects, outlines required LDM elements (storage, management, synchronization, security, APIs and privacy/policy functions), analyses compatibility with the ITS‑Station reference architecture, and highlights gaps where further specification or harmonization is needed. The report is intended to inform standards work and stakeholders rather than to define mandatory technical specifications.

Key topics and requirements

• Definition and role of the Local Dynamic Map (LDM) as an ITS‑Station subsystem.
• Four‑layer LDM concept: static map data, supplementary static content, temporary/dynamic conditions, and highly dynamic moving‑object data.
• Data elements, message types and protocols used as inputs/outputs (e.g., CAM/DENM, traffic broadcasts, centre feeds).
• Architectural models and example implementations from major R&D projects and vendors.
• Synchronization mechanisms for distributed LDMs (vehicle‑to‑vehicle, roadside, central systems).
• Geo‑location and time referencing considerations for map objects and events.
• Security, data integrity, access control and privacy/policy management for LDM content.
• APIs and service access points (SAPs) for application access and broker/arbiter functions.
• Gap analysis and recommendations for future standardization and interoperability work.

Typical use and users

Used as a reference and state‑of‑the‑art summary by ITS architects, automotive OEMs and Tier‑1 suppliers, telematics and map‑data providers, roadside infrastructure and traffic management authorities, C‑ITS application developers, researchers and standards bodies. It informs design choices for LDM implementations, interoperability planning, and standards development activities.

Related standards

Documents and deliverables commonly referenced with or following on from ISO/TR 17424:2015 include the ISO/TS and ISO/TR series for cooperative ITS (for example the ISO/TR 17427 series and ISO/TS 17429), the formal Local Dynamic Map standard ISO 18750 (published as an LDM specification after this TR), the ITS‑Station architecture (ISO 21217), regional ITS message/profile standards (ETSI/CEN message standards such as CAM/DENM and related ETSI TS work), data exchange frameworks (e.g., DATEX/DATEX II), and industry message sets such as SAE J2735. ISO/TR 17424 is an informative survey; formal normative LDM definitions and data object models were developed subsequently in ISO 18750 and related deliverables.

FAQ

Q: What is this standard?

A: ISO/TR 17424:2015 is a Technical Report that surveys the state of the art of Local Dynamic Maps (LDMs) in cooperative intelligent transport systems, summarising architectures, implementations and standardization activity and providing a gap analysis and recommendations.

Q: What does it cover?

A: It covers LDM concepts and architectures, the four‑layer logical LDM model, required LDM elements (storage, management, security, policy, APIs), data sources and protocols, geo‑referencing/time referencing issues, synchronization of distributed LDMs, and a gap analysis against existing standards.

Q: Who typically uses it?

A: ITS system designers, vehicle OEMs and suppliers, map and data providers, roadside infrastructure operators, traffic authorities, C‑ITS application developers, researchers and standards organizations use the report for guidance and to plan interoperability and standards work.

Q: Is it current or superseded?

A: ISO/TR 17424:2015 remains a published Technical Report that documented state‑of‑the‑art knowledge in 2015. Subsequent normative work on Local Dynamic Maps resulted in ISO 18750 (Local Dynamic Map), which provides formal specifications for LDM data objects and interfaces; ISO 18750 was published after this TR (initially in 2018 and later revised). Users implementing LDMs should consult ISO 18750 and later revisions for normative requirements while using ISO/TR 17424 as historical and contextual background.

Q: Is it part of a series?

A: It is part of the cooperative ITS family of ISO technical reports and specifications produced by ISO/TC 204. It is referenced alongside related TRs and TSs (for example the ISO/TR 17427 series, ISO/TS work on ITS facilities and ITS‑Station architectures) and complements later LDM standardisation (ISO 18750).

Q: What are the key keywords?

A: Local Dynamic Map, LDM, cooperative systems, ITS, ITS‑Station, V2X, synchronization, geo‑referencing, dynamic map layers, data integrity, APIs.
