1 Scope
This part of ISO/TS 21219 specifies the TPEG application: Traffic Event Compact (TEC). The TEC application
has been specifically designed to support information about traffic events (e.g. road
works, traffic jams). A specific form of traffic events are local hazard warnings which, being safety-related messages, are sent with high priority to warn a driver
that may encounter dangerous situations (e.g. black-ice, accident beyond curves, obstacles
on road, etc.) unexpectedly.
Generally, the Traffic Event Compact 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).
