Overview
ISO 14815:2005 - Road transport and traffic telematics - Automatic vehicle and equipment identification - System specifications - provides a generic system specification for Automatic Vehicle Identification (AVI) and Automatic Equipment Identification (AEI) in the road transport domain. The standard defines a framework for nominal interoperability (particularly over a DSRC link), allowing system specifiers to select performance classes and operating conditions while ensuring compatible identification between On‑Board Equipment (OBE) and Fixed Equipment (FE).
Key Topics and Requirements
- Scope and core components
- Defines core elements required for AVI/AEI: a communication link (e.g., DSRC), a reference architecture, common data structures, and operating/environmental parameter classes.
- Architecture and operation
- Supports both stand‑alone AVI/AEI systems and AVI/AEI as a function within other RTTT/TICS systems.
- Describes physical architecture and transaction semantics (e.g., successful AVI/AEI transaction, shadowing concepts).
- Data structures and encoding
- Recommends use of ASN.1 Packed Encoding Rules (PER) for data structure elements to maximize interoperability.
- Performance classes and categories
- Provides classes and categories to specify environmental and operational requirements (e.g., “ruggedized” vs. “standard”), enabling trade‑offs between cost and performance.
- Air interface and operating parameters
- Addresses air‑interface aspects and detailed operational parameters that influence successful read transactions.
- Test, compliance and certification
- Specifies test requirements and classification procedures for components; suppliers must declare classification for each physically separated component to claim compliance.
- Non‑technical considerations
- Discusses privacy and anonymity topics in the context of related documents (not handled directly in this standard).
- Safety, environmental and marking
- Includes normative annexes on environmental test parameters, safety, marking of equipment, and compliance procedures.
Applications
- Designing interoperable vehicle/equipment identification systems for tolling, access control, fleet management, enforcement, and traffic data collection.
- Specifying requirements for DSRC‑based identification deployments where cross‑border or multi‑operator nominal interoperability is required.
- Defining component classification and test plans for manufacturers and integrators of OBE and FE.
Who should use this standard
- ITS/RTTT system specifiers and architects
- Transportation authorities and tolling agencies
- OBE and FE manufacturers and integrators
- Test labs, accredited independent testing bodies, and certification organizations
- Consultants and system integrators working on DSRC and vehicle identification systems
