Intelligent transport systems - Roadside modules SNMP data interface - Part 7: Support features

PUBLISH DATE 2022
ISO/TS 20684-7:2022

Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS (C-ITS) environments, etc.

Field devices often need to exchange information with other external entities (managers). Field devices can be quite complex, necessitating the standardization of many data concepts for exchange. As such, the ISOΒ 20684 series is divided into several individual parts.

This document specifies user needs, requirements, and design elements that are normatively used by other parts of the ISOΒ 20684 series. Specifically, it defines:

  • an internal field device clock,
  • a mechanism for grouping object values together to provide for more efficient transfer of data, and
  • formal requirements for the SNMP target and target parameters as defined in IETF RFC 3413.

NOTE 1: There are similarities between certain portions of NTCIP 1103 and NTCIP 1201 and this document.

NOTE 2: ISO 20684-1 provides additional details about how the ISOΒ 20684 series relates to the overall ITS architecture.
