DD ENV 12313-2-1998 PDF

Full title and description

STB DD ENV 12313-2:1998 — Traffic and traveller information (TTI). TTI messages via traffic message coding — Event and information codes for Radio Data System — Traffic Message Channel (RDS‑TMC). This part defines the Events and supplementary information lists used to encode traffic and travel messages (ALERT‑C / RDS‑TMC message content) for distribution via radio data systems.

Abstract

This document provides the standardized list and descriptions of traffic event types, supplementary information fields and forecast/event qualifiers appropriate for encoding TTI (Traffic and Traveller Information) messages to be carried in the RDS‑TMC channel using the ALERT‑C coding approach. It is intended to be used together with the coding protocol (Part 1) that defines message structure and transmission.

General information

• Status: Superseded / replaced (national adoption as DD ENV; later revised by EN/ISO editions).
• Publication date: 1998 (national publication dates vary — examples include 15 January 1998 and April 1998).
• Publisher: Originally an ENV issued under CEN; published/adopted nationally (example: BSI as DD ENV).
• ICS / categories: 35.240.60 (Intelligent transport systems / IT applications in transport).
• Edition / version: DD ENV 12313-2:1998 (nationally adopted version of ENV 12313‑2:1997).
• Number of pages: Varies by national publication and format — commonly reported in the range ~50–62 pages (examples: 50, 58, 62 pages listed in different catalogues/editions).

Scope

The scope covers the definition and description of event codes, supplementary information codes and forecast/event qualifiers for use when encoding traffic and traveller information messages to be transmitted over the Radio Data System Traffic Message Channel (RDS‑TMC). It provides the canonical Events List and related code-sets intended for interoperable distribution of traffic messages between traffic data providers, broadcasters, navigation system vendors and end-user systems. The part is to be used in combination with the coding protocol (Part 1) that defines message syntax and transmission.

Key topics and requirements

• Standardized Events List for traffic incidents, roadworks, obstructions, weather-related effects, and other transport-related events.
• Supplementary information codes to qualify events (severity, direction, lanes affected, duration/expected end time, speed reduction, etc.).
• Forecast / planned-event codes for scheduled works or predictable disruptions.
• Designed for use with ALERT‑C encoding and RDS‑TMC message carrying mechanisms; requires Part 1 for protocol/message structure.
• Intended to enable interoperable TTI distribution across broadcasters, road authorities and navigation service providers.

Typical use and users

Used by national and regional road authorities, traffic information service providers, radio broadcasters implementing RDS‑TMC, navigation system manufacturers and ITS (Intelligent Transport Systems) integrators to encode and exchange standardized traffic and travel messages for in‑vehicle or receiver‑based navigation and travel information services.

Related standards

Related and follow-up standards include ENV 12313‑1 (coding protocol / message structure for RDS‑TMC), EN/ISO 14819‑2 (subsequent editions that revised and superseded ENV 12313‑2), and EN 50067 (RDS specification for VHF/FM broadcasting). Later consolidated revisions appear under EN ISO 14819‑2 (2003) and ISO 14819‑2 (2013) editions.

FAQ

Q: What is this standard?

A: It is the DD ENV 12313-2:1998 specification defining the event and information code lists used to encode traffic and traveller information messages for transmission via the Radio Data System Traffic Message Channel (RDS‑TMC).

Q: What does it cover?

A: It lists and describes the traffic event types, supplementary information items and forecast/qualifier codes used when encoding TTI messages (ALERT‑C) for RDS‑TMC delivery; it does not itself define the message protocol syntax (see Part 1 for that).

Q: Who typically uses it?

A: Road and traffic authorities, traffic data suppliers, radio broadcasters using RDS‑TMC, ITS integrators and navigation system manufacturers that consume or produce TTI messages. These stakeholders use the code lists to ensure messages are interoperable across systems and borders.

Q: Is it current or superseded?

A: Superseded — DD ENV 12313‑2:1998 was later incorporated into and revised by subsequent EN/ISO publications (EN/ISO 14819‑2 editions, including a 2003 revision and later ISO 14819‑2 updates). Implementers are normally directed to the latest EN/ISO 14819‑2 edition for current code lists and clarifications.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ENV 12313 series (Part 1 covers the coding protocol/message structure for RDS‑TMC). The two parts are intended to be used together for full implementation of ALERT‑C encoded TTI messages.

Q: What are the key keywords?

A: TTI, RDS‑TMC, ALERT‑C, event codes, supplementary information, traffic messages, intelligent transport systems.
