ISO 15638-24:2021

Overview

ISO 15638-24:2021 - part of the ISO 15638 TARV series - defines a framework for safety information provisioning to regulated commercial freight vehicles. Building on the TARV architecture (ISO 15638-1 and ISO 15638-21), Part 24 standardizes an unregulated service architecture for delivering safety advisory information (non-enforcement, and optionally regulated application services where jurisdictions require them). The goal is safer road transport of heavy freight by providing timely traffic, incident and safety advice to drivers/operators via in-vehicle systems, on-board communication units, and V2X paths that may include roadside sensors.

Key topics and technical requirements

• Framework and architecture: Adopts the ISO 15638 basic TARV architecture for interactions between in-vehicle systems, on-board communication units and application service providers (ASP).
• Service types: Defines unregulated application services using generic vehicle data, and services that combine vehicle data with additional application-specific inputs (including roadside sensors).
• Concept of operations: Goals, policies, stakeholder interactions and operational roles (prime service provider, application service provider, driver/operator roles).
• Sequence of operations: Includes commands and transactions (e.g., GET TARV LDT, CREATE and GET core data) and common sequences for information provisioning.
• Quality of service & testing: Requirements for QoS, test procedures and performance monitoring to ensure reliable safety information delivery.
• Security and data governance: Information security, data access control policies, approval criteria for in-vehicle systems (IVSs), service providers and roadside sensors.
• Data quality & naming: Standards for data content, quality, naming and software engineering quality systems.
• Compliance and conformance: Conformance clauses and guidance on audits, approval and intellectual property declarations.

Practical applications

• Real-time delivery of traffic status, incidents and advisory messages to heavy goods vehicle drivers to improve reaction time and maneuvering safety.
• Fleet safety management systems that provide remote safety advisories without enforcement actions.
• Integration of roadside sensor feeds and V2X communications to enrich vehicle-specific safety advice.
• Use in transport operator control centers, telematics service providers, and ITS deployments to reduce accidents and improve operational safety.

Who should use this standard

• Telematics and ITS application service providers (ASPs)
• Fleet operators and vehicle OEMs integrating in-vehicle systems (IVS)
• Road authorities and jurisdictions designing non-enforcement safety services
• Roadside sensor manufacturers and V2X solution vendors
• Safety management organizations and system integrators
