Intelligent transport systems — Data exchange involving roadside modules communication — Part 2: Centre to field device communications using Simple Network Management Protocol (SNMP)

This document specifies a mechanism for exchanging data and messages in the following cases:

a) exchange between a traffic management centre and ITS roadside equipment for traffic management;

b) exchange between ITS roadside equipment used for traffic management.

This document is not applicable to:

— communication between traffic management centres and in-vehicle units;

— communication between ITS roadside equipment and in-vehicle units;

— in-vehicle communication;

— in-cabinet communication;

— motion video transmission from a camera or recorded media.

This document is suitable for use when both of the following conditions apply:

1) The data to be exchanged can be defined as one or more elements that can be retrieved or stored – SNMP can support a wide variety of devices and has adopted the concept of a management information base (MIB), which identifies the configuration, control and monitoring parameters for ITS roadside equipment. This standardized approach is commonly used for network management applications for devices such as routers, switches, bridges and firewalls. It is also used in many regions to control devices such as dynamic message signs.

2) Guaranteed, de
