ISO/TS 26048-1:2025

Overview

ISO/TS 26048-1:2025 - "Intelligent transport systems - Field device Simple Network Management Protocol (SNMP) data interface - Part 1: Global objects" defines the global data model and normative content for managing ITS field devices using an SNMP-based interface. The technical specification introduces the ISO 26048 series, provides common objects and definitions referenced by later parts, and establishes functional requirements for a management interface in an SNMPv3 environment. It does not prescribe management-station logic, lower-layer transport protocols, or internal device design.

Key topics and technical requirements

• SNMP/SNMPv3 environment: Assumes an SNMPv3-based interface (security and management features) and defines terminology, MIB format conventions and access patterns.
• Global objects and MIBs: Specifies global Management Information Base (MIB) structure, ASN.1 usage and MIB filenames/maintenance practices for consistent device data exchange.
• Security & access control: Functional requirements for authentication, user access control, and monitoring of failed access attempts aligned with SNMPv3 security features.
• Device management features: Definitions and requirements for features such as clock management (UTC/local/daylight saving), commands, actions, controllers, and conditional triggers.
• Monitoring & logging: Requirements for monitoring device components (power, enclosure, environment), event logging, user-defined snapshots, and series of snapshots for diagnostics and auditing.
• Notifications and triggers: Models for triggers (scheduled, day-plan, condition-based), notification channels and a notification factory to configure and deliver alerts.
• Conformance and constraints: Table design and access constraints, conformance patterns and expectations for implementers to ensure interoperability.
• Efficiency and scalability: Design considerations for efficient data exchange and handling of complex device configurations.

Applications and who uses it

ISO/TS 26048-1:2025 is intended for:

• Traffic authorities and ITS operators who need standardized management of traffic signals, dynamic message signs, weather stations, traffic sensors and roadside connected equipment.
• Field device manufacturers implementing SNMP MIBs to expose configuration, status and control interfaces.
• System integrators and network managers building management systems, NMS tools or cloud platforms that monitor and control ITS field devices.
• Software developers and OEMs creating management station software, telemetry collectors or event/notification services.

Practical applications include remote configuration, alarm/notification handling, preventive maintenance, device health monitoring, firmware/update orchestration (future parts) and secure operational control.

Related standards

• ISO 15784-2 (assumed SNMPv3 environment reference)
• NTCIP 1103 and NTCIP 1201 (source concepts; ISO/TS 26048-1 updates design to improve security and interoperability)
