Systèmes intelligents de transport — Informations sur le trafic et le tourisme via le groupe expert du protocole de transport, génération 2 (TPEG2) — Partie 15: Événement trafic compact (TPEG2-TEC)

This document specifies the "traffic event compact" (TEC) TPEG application. The TEC application has been specifically designed to support information about traffic events (e.g. road works, traffic jams). A specific form of traffic event is local hazard warnings which, being safety-related messages, are sent with high priority to warn a driver of unexpected dangerous situations (e.g. black-ice, accident beyond curves, obstacles on road, etc.).

Generally, the TEC application is designed to allow receivers to:

—    

ensure travel safety for the driver;

—    

enable the calculation of alternative routes;

—    

avoid delays (e.g. traffic jams);

—    

warn the driver of obstructions on route; and

—    

provide the driver with information on infrastructural problems (e.g. closed petrol stations, non-functioning emergency telephones).
