Overview
SIST-TS ISO/TS 15007-2:2018 provides comprehensive guidelines for the measurement and analysis of driver visual behaviour in relation to Transport Information and Control Systems (TICS) in road vehicles. Developed by SIST in alignment with the ISO framework, this technical specification details recommended equipment and procedural best practices for both real-world (on-road) and simulated driving environments. The aim is to enable systematic evaluation of TICS impacts on driver attention, supporting safer interface design and technology integration by ensuring the collection of reliable, valid visual behaviour metrics.
Key Topics
- Evaluation Trial Planning: Guidance on designing assessment studies, including selection of representative driver samples based on age, gender, visual ability, and driving experience.
- Equipment Guidelines: Recommendations for specifying, installing, and validating eye-tracking and related data acquisition systems, covering head-mounted and remote setups.
- Data Capture and Synchronization: Procedures for recording driver gaze, road scenes, and in-cabin actions, emphasizing the importance of synchronized data streams for robust analysis.
- Data Reduction and Analysis: Step-by-step processes for manual and automated reduction of raw data into meaningful metrics, such as glance number, duration, and distribution across areas of interest.
- Interpretation of Metrics: Standard definitions and example interpretations for visual demand metrics (e.g., glance frequency, total glance time, mean glance duration, eyes-off-road time).
- Quality Assurance: Strategies for calibration, validation, and management of data quality issues and artefacts (e.g., calibration drift, data dropouts, tracking errors).
Applications
SIST-TS ISO/TS 15007-2:2018 finds application in domains such as:
- Human Factors Research: Facilitates ergonomic evaluations of vehicle interfaces, supporting regulatory and usability studies.
- Automotive Engineering: Assists manufacturers and designers in quantifying the distraction risk posed by in-vehicle displays, infotainment systems, or advanced driver assistance features.
- Regulatory Compliance: Supports authorities and standardization bodies seeking harmonized, evidence-based approaches for assessing TICS safety and driver workload.
- Simulator Studies: Provides structured methodologies for evaluating driver visual behaviour in controlled experimental settings, crucial for testing new interfaces or automated functions.
- Road Safety Assessment: Enables the development and validation of countermeasures to minimize driver distraction and optimize information delivery.
- Product Development: Informs best practices in the specification, placement, and operation of user interfaces and control displays to enhance usability and safety.
Related Standards
For a more holistic approach to the evaluation of driver visual behaviour and TICS, consider these complementary standards:
- ISO 15007-1: Road vehicles – Measurement of driver visual behaviour with respect to transport information and control systems – Part 1: Definitions and parameters. Establishes key terminology and measurement fundamentals referenced extensively in Part 2.
- ISO 26262: Road vehicles – Functional safety. Addresses broader vehicle system safety, where human-machine interaction is a key element.
- ISO 9241-210: Ergonomics of human-system interaction – Human-centred design for interactive systems. Provides principles applicable to automotive interface assessment.
