1. Definitions

Alarm code id

Identity of an alarm

The examples in this document are defined according to the following format: Ayyyy, where yyyy is a unique number.

Command code id

Identity of a command

The examples in this document are defined according to the following format: Myyyy where yyyy is a unique number.

External alarm code id

Manufacturer specific alarm code and alarm description. Includes manufacturer, model, internal alarm code och additional alarm description.

External NTS alarm code id

Alarm code in order to identify alarm type during communication with NTS

DATEX II

European standard for message exchange between traffic systems (www.datex2.eu)

Functional position

Provides command options for a site. For instance, “start” or “stop” It is meant to be used for the entire site and not for an individual component. It can be implemented using a command and can be read from the site using the aggregated status message.

Functional state

Not used

ITS site

Road side equipment. Covers both field level and local level

JSON

JavaScript Object Notation

Local road side equipment

See ITS site

Maneuver

Provides command options for one or many individual components. For instance, “start” or “stop”. It can be implemented using a command and can be read from the site using a corresponding status message.

Designed to be used with NTS.

NTS

National Traffic management system at the Swedish Transport Administration

NTS object

Used for objects in NTS

All control and supervision related functions in NTS consist of NTS objects.

An NTS object can represent one or many components.

External NTS id

Identitiy for an NTS object used in communication between NTS and other systems

The format is 5 integers and is unique for the site. It is defined in cooperation with representatives from NTS.

NTS-Object type

A NTS object type is a classification of NTS objects. Determines among other things which functional positions that are possible for the NTS object.

Component

A component can have one or more statuses that may change depending on changes of circumstance of the component or control of the component from external source. Communication with the component is made using exchange of signals, e.g. commands, statuses and alarms.

A component can represent physical equipment or abstract concepts E.g. a camera, a control flow algorithm or a group of signs.

A component is identified using Component ID. Please note that a component is not necessarily the same thing as an NTS object.

Component type

A component type is a classification of components that controls the properties of all the components of the same component type. The component type determines how the component is presented in supervision system, how it is grouped and which functional positions, alarm codes, commands and statuses that exists for that component type.

Component id

Identifies a component.

Parameter

Used for modification of technical or autonomous traffic parameters of the equipment. Can be implemented using commands and statuses.

RSMP

Road Side Message Protocol

RSMP Nordic

Organization for maintaining and develop the RSMP protocol. Collaboration between a group of Nordic road authorities.

Site

See ITS site

Site id

Site identity. Used in order to refer to a “logical” identity of a site.

Supervision system

Control and supervision system for regional and/or national level

SXL

Signal exchange list. Defines which messages types (signals) which is possible to send to a specific equipment or component. E.g. alarms, statuses and commands

Status code id

Identitiy for a status

The examples in this document are defined according to the following format: Syyyy where yyyy is a unique number.

TCP/IP

Transfer Control Protocol/Internet Protocol

W3C

World Wide Web Consortium

XML

eXtensible Markup Language
