Integrated transport information, management and control (ISO TC 204 WG 9)¶
Domain of interest¶
The purpose of WG9 is to reduce the risks undertaken by infrastructure owners and operators (IOOs) by promoting interoperability between centres as well as centres and roadside equipment. This includes standardizing transport management and control information and protocols for traffic management.
WG9 activities include standardization of:
- data exchanges between transport management centres,
- data exchanges between centres and roadside equipment,
- data exchanges between roadside equipment
Roadside equipment includes signal control devices, information boards and sensors installed along roads
Field device Simple Network Management Protocol (SNMP) data interface¶
Overview ¶
The ISO 26048 series defines data that can be used to manage field devices, including device configuration, control and monitoring. Field devices can be quite complex, necessitating the standardization of many data concepts for exchange. As such, the ISO 26048 series is divided into several individual parts.
The scope of the ISO 26048 series does not define the logic used by the management station, the underlying protocols used to exchange the defined data elements, or internal design of the field device. However, the ISO 26048 series does define functional requirements on the interface and assumes an interface based on an SNMPv3 environment as specified by ISO 15784-2.
ISO/TS 26048-1:2025 Intelligent transport systems — Field device Simple Network Management Protocol (SNMP) data interface — Part 1: Global objects
Status: Approved
Abstract: This document (ISO/TS 26048-1) introduces the ISO 26048 series, provides content that is normatively referenced in subsequent parts, and defines data that is applicable to the management of a wide range of field devices.
Description:
⚠️ NOTE Many of the concepts defined in this document were derived from NTCIP 1103 and NTCIP 1201, however, the design has been updated to better address security concerns. It is expected that future versions of NTCIP will migrate to the design defined in this document.

ISO/AWI TS 26048-3 Intelligent transport systems — Field device SNMP data interface — Part 3: Variable and dynamic message signs
Status: Edition 1 (under development)
Abstract: This document identifies basic user needs for the management of light-emitting diode (LED) matrix Variable and dynamic message signs(VDMSs) and traces these needs to interoperable designs. This includes the ability to identify the device, its capabilities, and its status.
Description:
Variable and dynamic message signs(VDMSs) are installed in areas where traffic managers identify a frequent need to convey information to the travelling public, such as upstream from interchanges to alert the public to downstream congestion in time for them to alter their routes. This allows traffic managers to improve the efficiency, safety, and quality of traveller journeys. In order to manage the operation of a VDMS and the messages displayed, information exchange between the management systems and the VDMS is needed.
