ISO/TR 22086-1:2019 PDF

Overview

ISO/TR 22086-1:2019 - Intelligent transport systems (ITS) - Network based precise positioning infrastructure for land transportation - Part 1: General information and use case definitions - provides a framework for delivering lane‑level GNSS positioning and integrity monitoring to land-transport users with low‑cost nomadic devices. The technical report defines a reference architecture for the NETPPI‑LT (network‑based precise positioning infrastructure for land transportation), outlines real‑time service guidelines (GNSS corrections and integrity), and specifies practical use‑case clusters to support ITS services that demand sub‑meter accuracy.

Key topics and requirements

• Reference architecture: Roles and data flows for key NETPPI‑LT components - reference stations, control stations, monitoring stations, base stations, and nomadic devices.
• GNSS corrections and integrity: Guidelines for generating and distributing carrier‑phase correction data and integrity information to nomadic devices over wireless links.
• Service delivery: Real‑time positioning service concepts using GNSS carrier‑phase measurements aided by wireless broadcast/communication channels (e.g., LTE/5G, WAVE, DSRC, DAB/DMB).
• Performance expectations: Framework targets lane‑level (sub‑meter) positioning and high confidence levels (document notes requirements such as ≥95% confidence for certain applications).
• Operational considerations: Recommendations for reference station siting (clear sky view, sensor monitoring), control station processing (low latency, anomaly detection), and system monitoring/feedback.
• Use‑case definitions: Clustered examples for application scenarios, including safe driving, intersection approach and clearance, and public transportation safety, to guide implementation and testing.

Applications and who uses it

ISO/TR 22086-1 is intended for organizations designing, deploying, or operating ITS services that require reliable lane‑level positioning:

• Automotive OEMs and ADAS/autonomous‑vehicle teams integrating positioning and integrity services.
• GNSS service providers and network operators (cellular, broadcast) delivering correction/ integrity data.
• ITS infrastructure engineers, traffic management authorities, and city planners implementing NETPPI‑LT components.
• Suppliers of nomadic devices, positioning modules, and safety‑critical ITS applications.
• Standards bodies and researchers aligning interfaces and functional requirements (see Part 2 for device functional requirements and data interfaces).

Related standards

• ISO/TR 22086 series - Part 2 (under development at the time) addresses functional requirements and data interfaces for nomadic devices and infrastructure.
• The report complements GNSS service recommendations from RTCM and industry GNSS/ITS interoperability guidelines.
