ISO 15638-11:2014

Overview

ISO 15638-11:2014 - "Intelligent transport systems - Framework for cooperative telematics applications for regulated vehicles (TARV) - Part 11: Driver work records" defines how Driver Work Records (DWR) are specified, exchanged and accessed within a TARV environment. The standard describes the high-level service definition a service provider must offer, the means to realize that service, and the required application data, naming, content and quality that an In-Vehicle System (IVS) must deliver. ISO 15638-11 provides a framework enabling regulators to require, or optionally support, electronic DWR services without prescribing exact instantiation details or acceptable value ranges.

Key technical topics and requirements

• Service definition: High-level description of the DWR application service (what the service must provide, not the low-level instantiation).
• Data content and naming: Specifications for DWR file structure, metadata and minimum content requirements required to support regulatory use.
• Access methods: Defined approaches for authorized access to driver work record data from IVS and back-office systems.
• Quality of service (QoS): Requirements and metrics for data quality and service performance expected from IVS and service providers.
• Test and approval provisions: Test requirements, independent testing guidance and approval of IVSs and service providers to ensure compliance.
• Information security & access control: Provisions for secure handling, access policies, and auditing of DWR data.
• Software engineering & auditing: Expectations for development quality systems, monitoring stations, and audit processes for regulated services.
• Protocol and data module references: Informative annexes include ASN.1 modules for data concepts and guidance on independent protocol testing.

Practical applications and users

ISO 15638-11 is intended for:

• Regulators and approval authorities defining electronic driver record requirements and enforcement procedures.
• Service providers delivering telematics or DWR services to jurisdictions.
• IVS and telematics equipment manufacturers implementing DWR data exchange, QoS and security features.
• Fleet operators, auditors and enforcement agencies who consume or verify driver work records for compliance, fatigue management, duty time tracking, and auditing. Practical deployments include electronic on-board records, integration with digital tachographs, fatigue-management systems, and back-office compliance reporting.

Related standards

• ISO 15638 series (Parts 1–19) - TARV framework, architecture and regulated applications (e.g., Parts 1, 2 (CALM), 3, 5, 9, 10).
• References to CALM and other ITS standards are used where applicable.
• Annexes in ISO 15638-11 provide ASN.1 modules and independent testing guidance to support implementation and interoperability.
