ISO 13184-3:2017

Overview

ISO 13184-3:2017 - "Intelligent transport systems (ITS) - Guidance protocol via personal ITS station for advisory safety systems - Part 3: Road guidance protocol (RGP) conformance test specification" - defines conformance tests for supplier self-assessment of a Personal ITS Station (P-ITS-S) implementation. The document specifies test cases based on the use cases in ISO/TR 13184‑1 and the requirements in ISO 13184‑2, focusing on application‑level message exchange (Data eXchange Message, DXM) for safety warning and parking guide services between:

• Vehicle ITS Station (V-ITS-S) (in-vehicle),
• Personal ITS Station (P-ITS-S) (nomadic device or pedestrian device), and
• Roadside ITS Station (R-ITS-S) (roadside infrastructure).

The primary purpose is to help P-ITS-S system providers build and verify their systems against standardized conformance test cases so implementations meet expected functional requirements.

Key Topics and Requirements

• Conformance test principles and clustering - test case structure, pass/fail criteria, and clustering of tests for efficient assessment.
• Test case structure - includes configuration, preamble (setup state), execution steps, and postamble (tear-down and results).
• DXM application‑level compliance - verifying correct message formats, triggers and behaviors for safety warning and parking guide services.
• Functional scenarios covered - multiple clusters addressing real-world road situations, such as:
  • Crossroads with traffic signals (signal violations, pedestrians, congestion),
  • Crossroads without signals,
  • Parking guidance (entry, on‑demand search),
  • Risky environment alarms (oncoming vehicles, curves, severe weather, temporary occupations, emergency vehicles).
• Self-conformance assessment - enables suppliers to perform final-stage functional verification before deployment.

Applications and Who Uses It

• P-ITS-S system providers and app developers - to design, implement and validate personal ITS devices (nomadic/handheld) and in-vehicle companion apps.
• Vehicle OEMs and Tier‑1 suppliers - integrating P-ITS-S features with V-ITS-S and verifying interoperability.
• Roadside equipment manufacturers and ITS integrators - to ensure R-ITS-S interoperability with personal stations.
• Test laboratories and QA teams - to structure formal conformance tests and produce certification evidence.
• Transport authorities and regulators - to reference standardized test methodology when assessing safety advisory services.

Related Standards

• ISO/TR 13184‑1 (use-case definition)
• ISO 13184‑2 (requirements for guidance protocol)
  These parts together support standardized RGP deployment and interoperability across ITS ecosystems.
