Overview
ISO/TR 24856:2025 - Intelligent transport systems - Mobility integration - Role model of the human-centric predictive risk information provisioning service - defines a conceptual role model and operational framework for providing predictive safety risk information to road users. The Technical Report focuses primarily on non-enforcement applications (with enforcement services out of scope), adopting a human‑centric approach that considers all road users - including vulnerable road users (VRUs) and automated vehicles (AVs). It builds on ISO/TR 4445 and emphasizes digital platforms (clouds), ITS stations, and service‑provider transactions to deliver risk information ahead of a mobility entity’s position.
Key topics
- Role model architecture: baseline components and role relationships for service providers, ITS stations and mobility users (see sections on baseline, smart city sensor data, 3D HD point‑cloud maps, digital infrastructure and communications).
- Human‑centric safety provisioning: principles for predicting risks by understanding traffic environment and human behaviours to provide timely, actionable warnings.
- Data and platform elements: aggregation of sensor data (smart city sensors, high‑definition mapping), cloud/digital platforms, APIs and communication channels to transmit predictive risk information.
- Application layer & functional models: options for service roles, transaction flows and potential certification of service providers to ensure trust and interoperability.
- Gap and overlap analysis: comparison with existing time‑critical safety standards, identifying that predictive provisioning fills a different (earlier) part of the safety timeline.
- Use cases: examples such as work zones, merging traffic, tail‑end crashes, blind intersections and obscured crossing pedestrians.
- AI and automated driving relevance: potential integration with AI processing in AVs for large‑scale, fast data processing and decision support.
Practical applications
- Early warning services to reduce incidents by informing drivers, cyclists, pedestrians and AVs of emerging downstream risks.
- Smart city integrations that combine sensor networks, 3D HD maps and digital platforms to deliver predictive traffic and incident advisories.
- Mobility service providers and navigation vendors embedding predictive alerts into routing and driver assistance.
- Support for authorities and traffic managers to deploy non‑enforcement safety enhancements (with potential future linkage to enforcement frameworks).
Who should use this standard
- ITS architects, service providers and integrators
- Smart city and municipal traffic agencies
- Mobility and fleet operators, map and sensor vendors
- Automated driving system developers and AI/AV integrators
- Telecom and cloud platform providers involved in ITS data exchange
Related standards
- ISO/TR 4445 (role model for ITS service applications)
- ISO/TS 24315 series (enforcement‑focused ITS services)
- Relevant communications and security standards referenced in the gap analysis (e.g., ISO 21217, ETSI/IEEE ITS specifications)
