Overview
ISO/TS 25114:2010 - Intelligent transport systems - Probe data reporting management (PDRM) - defines a common framework and concrete message definitions for managing probe data reporting from vehicles to land-based centres. The Technical Specification standardizes how a probe processing centre issues PDRM instructions to probe vehicles to optimize reporting, improve airtime efficiency and enable interoperable probe vehicle systems. The document specifies a reference architecture, a basic data framework, and XML notations for PDRM instructions and message structures.
Key Topics and Requirements
- Reference architecture for probe vehicle systems and probe data that incorporates PDRM and aligns with ISO 22837.
- PDRM message types and structures, including messages that:
- contain one or more PDRM instructions,
- start/stop all probe reporting,
- start/stop reporting of specific probe data elements,
- convey criteria for reporting particular probe elements.
- Instruction types explicitly defined:
- Data capture instruction,
- Threshold instruction (with elements such as Threshold and ThresholdDirection),
- Delta instruction (with DeltaValue, DeltaDirection, TimeDiff).
- PDRM common data elements and instruction-specific elements (e.g., PDRStartTime, PDRStopTime, Region, Heading, VehicleType, Reporting frequency).
- Basic data framework and rules for using PDRM instructions; required conditions for instructions and XML representation (ASN.1 and XML notation references).
- Emphasis on communication efficiency (reducing airtime usage) and secure, non-identifying probe messages (no vehicle/occupant identifiers in probe messages).
Applications and Who Uses It
- System developers and architects designing probe vehicle systems, onboard data collection, and land-based probe processing centres.
- ITS integrators and telematics providers implementing efficient probe reporting and management.
- Vehicle manufacturers specifying onboard reporting behaviour compatible with wide-area probe data systems.
- Transport agencies and operators using probe data for traffic monitoring, travel-time estimation, and traffic management while controlling data collection costs.
- Developers creating PDRM-compliant message encoders/decoders (XML/ASN.1 implementations) and middleware for probe data exchange.
Related Standards
- ISO 22837:2009 - Vehicle probe data for wide area communications (reference architecture compatibility).
- ISO 14817 - Central Data Registry and Data Dictionaries (data definitions).
- ISO/IEC 8824-1 - ASN.1 notation (encoding reference).
- ISO 1000 - SI units (unit conventions).
ISO/TS 25114:2010 is useful where standardized, efficient, and interoperable probe data reporting is needed across multiple vehicle types, manufacturers, and ITS service providers.
